How To Start Seeds Inside A Grow Tent

How to Start Seeds Indoors Under Lights

Growing plants from seed is an excellent approach to increase the diversity of plants in your organic garden. The process of starting plants from seeds may take a little time and work, but it is one of the most rewarding gardening efforts you will ever do, and it is also one of the most effective methods to stretch your gardening budget. In order to successfully start seeds, make sure the container you choose is at least one or two inches deep and includes drainage holes. The potting media should be quick draining while yet being able to retain water.

You can start with the seeds and grow them all the way through in a sterile potting mix.

Warm water should be used, and the soil mix should be given enough of time to absorb moisture.

After that, fill the container to the top of it, leaving at least 1/4 inch of room.

  1. This stage of the process occurs when the right circumstances for germination are present, which might be disrupted by a lack of moisture, temperature, air movement, or light.
  2. When you have the correct seed starting materials from Planet Natural, it’s simple to get started.
  3. Ensure that the moisture is distributed evenly for effective seed germination.
  4. Keep a close eye on the moisture level in your containers; you may need to water them every day or store them inside a transparent plastic bag to prevent the potting mix from drying out completely.
  5. It is possible to purchase seed-starting kits that include a clear plastic dome on top and a watering tray below.
  6. The Hydrofarm Hot House is an excellent way to get your plants up and running.
  7. It’s simple to use – simply add your own beginning mix!

They are simple to use, since they are small enough to fit beneath most standard-sized seed flats while gently warming the root zone by 10-20°F above ambient temperatures.

Seedlings, or small plants, are created when seeds sprout and become larger than their original size.

Seedlings need more light than full grown plants, ideally as much as 16-18 hours a day.

Plant lights that are reasonably priced may be bought at many garden supply stores for less than $100.

We’ve discovered that a window sill, or even a sun porch, does not give adequate light for the development of robust, healthy, compact seedlings in the greenhouse.

Once the seedlings have emerged, position the light so that it is as close to the plants as feasible.

We provide our starters with 12 hours of daylight every day.

Everything a plant requires to survive and thrive is contained within the seed itself.

Planting the seedlings into larger containers when they have grown sufficiently is recommended.

The first true leaves that a seedling produces are generally the second set of true leaves that the seedling produces.

Gently pull the seedling from its original container with a fork or a chopstick, retaining as much of the root system as possible.

Designed to create bigger, better flowers and healthy plant development, the AgroSun DaySpot is a 60 watt grow light kit.

Incorporate the seedling into its new environment.

Maintain a gentle watering regimen for the new transplants and place them back near the light source until you detect signs of fresh growth, which will indicate that the surgery was successful.

Transplanting into the Garden

If everything goes according to plan, your seedlings should be ready to be transplanted in 5 to 10 weeks after they are started. However, you should not simply chuck them outside. It is preferable to introduce children to the vast outdoors in little steps. Begin with a few short excursions lasting only a couple of hours throughout the hottest portion of the day. Then progressively increase the number of hours until they have adapted, or hardened off, and may be planted outside (seeHardening Off Isn’t That Difficult).

The germination of healthy seedlings is predictable and usually always ensures uniform planting, whereas direct seeding might result in poor germination and gaps in rows if growing circumstances are less than ideal.

Prepare to carefully remove the young seedlings from their pots, taking care not to damage the root ball as much as possible when you do so.

Water the transplant soon after it is made with a seaweed extract solution to “seat” it and prevent transplant shock.

Video Transcript

It rained nonstop all night last night, making everything muddy and disgustingly filthy. With a lot of above clouds and a potential of thunderstorms later in the day, it’s probably best if I set up a grow tent right now, but I’m not sure. Sooo. Putting the tent together didn’t take me a whole day, but time got away from me and I had other things to take care of while I was doing it. It’s the next day, it’s completed: let’s go over it again. Please recall that I discussed everything that will be putting into our raised garden beds in the last video.

  • An 8-foot-high indoor grow tent measuring 2 feet by 4 feet by 8 feet is what we have.
  • As a result, we needed to regulate two important variables: light and temperature.
  • Allow me to come over and just show you around.
  • up there and down here on the side of the building.
  • Let us take you on a tour of the interior.
  • In addition, as you can see, it’s extremely well-insulated, allowing us to regulate the temperature of our heat sources within the tent while our seedlings are developing in our trays beneath our grow light.
  • Another great thing about it is that we can tighten the cables in so that no light, outside air, or heat can get into our tent while we’re not using them.

Please see the description box below for a link to additional information about this tent, or you can click on the I symbol at the top of your screen to learn more about it.

First and foremost, let’s discuss about storage containers.

In this case, using separate containers with a single seedling in each container is preferable than filling a big container with potting mix and seeds from several distinct varieties.

Most of the time, these plastic sheets with these little containers are referred to as cell flats, which is a slang term for them.

You may also use small individual plastic pots to hold your ingredients.

Fiber pots can be used as an alternative to plastic containers if you don’t want to use plastic.

Seedlings grown in these fiber or paper pots that decompose in the soil are particularly well suited for growing cucumbers and squash, which are difficult to transfer into larger containers.

And what these domes are particularly adept at is enabling light to pass through while simultaneously preventing moisture from leaving.

Make a note of the fact that these domes will need to be removed after the seedlings have grown to the point where they can touch them.

And the reason I’m starting with organic pots is that if our seedlings begin to outgrow them, we can easily break those pots apart, pull the seedling out, and transplant it into a larger organic pot at a later time.

So that takes care of our containers; let’s go on to the next component that we’re going to need, which is lighting.

These days, there are certain kinds of lights that are offered as grow lights, like as the one we’re now utilizing inside our grow tent.

Maintaining a close proximity between light sources and plants is important when using artificial lighting.

Two inches is a good starting point, but you want to make sure that the lights are not more than four inches over the tops of your seedlings at all times.

Please don’t do it.

If you are able, I would recommend developing some sort of basic timer to be included into your system, or simply keeping track of how long your lights are left on.

And the source of that heat will be a heating pad.

If you’re beginning seeds inside, they’ll germinate more quickly and grow better roots if the potting mix is kept at a comfortable temperature.

It is the mortality of small seedlings caused by infections on the surface of their potting mix that is being discussed.

Just make sure that if you use a timer to control the lights above the seedlings, you don’t forget to unplug the heat mats from the outlet.

Most commercial seed starting mixes will now comprise vermiculite and peat, rather than actual soil, as the primary ingredients.

Because they’re going to be sterile, they’re going to be lightweight, and they’re not going to contain any weed seeds that you might get if you mixed in soil.

The soil mix that we’re going to use to start our seedlings comprises peat, hummus, peat moss, and pearlite, all of which are beneficial to them.

Something along the lines of this will suffice.

These are entertaining.

How to Germinate Cannabis Seeds (Quick & Easy)

The most recent update was made on January 18, 2022. The process of causing cannabis seeds to sprout is referred to as germination. This occurs naturally underground, but it is not a completely dependable process in a well-organized grow-op. With cannabis, it is typically preferable to germinate the seed before planting it to ensure that the plant will develop and, eventually, provide a successful harvest of the plant. Even with high-quality cannabis seeds, duds are a typical occurrence. Growing these young plants in a more regulated environment than dirt can assist to limit the number of seeds that do not sprout, therefore saving the grower from a certain degree of disappointment.

The 3 Common Methods to Germinate Cannabis Seeds

Heat, water, and air are the only elements that cannabis seeds require in order to germinate and thrive. For as long as the seeds are still viable, anything that offers such conditions will result in a sprout. Therefore, while keeping seeds in warm or humid areas, certain measures should be taken. Image courtesy of lovingimages on Pixabay. The following approaches are all tested and truealternatives to the direct sowing of the seeds. Growers, on the other hand, should pay attention to the color of their seeds before trying any germination, since immature seeds will not germinate successfully.

Seeds that are more developed in hue are deeper in color, nearly brown in appearance.

1. Paper Towel Method

Heat, water, and air are all that are required for cannabis seeds to germinate and flourish. For as long as the seeds are still viable, anything that provides such conditions will result in a sprout. Therefore, while keeping seeds in warm or humid areas, some measures should be observed. Pixabay picture courtesy of lovingimages The methods listed below have all been tried and tested as alternatives to direct seeding of the seeds in the ground. But farmers should pay attention to the color of their seeds before attempting to germinate them since immature seeds will not germinate.

Maturity is indicated by a deeper coloration, nearly browning, of the seeds.

2. Soaking Overnight

When it comes to revitalizing older, dried-out seeds, a thorough soak can do the trick if done correctly and in a timely manner. After placing the seeds in a glass of warm water and transferring them to a dark setting, the taproot should begin to peek through after about 24 hours. If this has not happened, the seeds should be relocated to a new location since too much water might cause them to drown. The maximum suggested duration for this is 24-36 hours, and it is only necessary for seeds that have been exposed to the elements for an extended length of time.

Because of the possibility of drowning, this procedure is significantly riskier than the paper towel method; yet, it has the ability to rejuvenate older seeds.

3. Peat Pellets

The idea is to utilize a piece of growth material, such as peat pellets, which are readily available, and to plant the seeds directly into the growing medium. Preparation: Soak the pellets in warm water for a few minutes, then poke a small hole into them, approximately a half-inch deep and just large enough for a single seed to nestle snuggly inside. They may be watered and kept warm in this location, and they can even begin to grow root. The entire pellet will be moved to the location where the germinated plant will be grown in the near future.

The seed is subjected to very little trauma in this environment, and the trauma of transplanting is rendered moot.

Seed Starting Reflective Growing Tent W/ Lights

In the past, I used to start my seeds in the sunroom, which was not a popular choice with my wife. As a result, I decided to relocate my business to the basement. The problem with the basement is that it is too chilly for seedlings to germinate. As a result, I had to improvise. When I was in my local hardware shop, I came upon a roll of reflective bubble tape, which gave me the inspiration for this story. I’ve seen these fancy grow tents that people use and thought they were fantastic, but the price tag on them is too expensive.

As a result, I decided to create my own.

Step 1: Stuff You Will Need

This list may be incomplete, but I will do my best to fill in the gaps. Roll up the bubble tape that has been foil-coated. PVC bits at random Shelving Unit Made of Plastic Thumb Screw (also known as a thumb screwdriver) Tactile Self-Tapping ScrewsL bracket Some machine nuts and bolts are included. Sunseeker Light Fixtures or other T5 bulb fixtures that are functionally identical. Velcro tabs are used to hold things together.

Step 2: The Shelf. and the PVC Frame

The foil is a little fragile and does not want to unroll into its original shape, so I decided to create a simple and inexpensive PVC frame to hold it in place. To build a box, all you need is 1/2′ PVC and three way joints. The measurements were chosen based on the size of my shelf, and I made sure to leave enough of space between the shelf and the lights. Each side is approximately 3″ in length. Menards provided me with this shelf. Take it out of the box and put it together.

Step 3: The Foil

I trimmed the foil into a rectangle so that it would fit around the frame’s perimeter. It shouldn’t be too tight, but it should be snug enough to preserve its shape and look good. In order to be able to wrap it around and use it as a door, I intentionally left one of the sides longer while I was cutting it. After that, I used foil tape to secure all of the joints together. Looking back, you could probably just fold the foil around the frame instead of cutting it, but I loved the precise corners it gave the finished product.

To create a lovely overhang lip and a snug fit on the lid, I trimmed the sheet a little larger than I required to begin with. I cut lines into the paper to create a false corner, which I taped in place using foil tape, as well. For a better understanding, go to the illustrations.

Step 4: The Lights

To hang the lights on the shelf pole, I cut a piece of PVC with a larger diameter and drilled a hole in it for the thumb screw to fit through. This holds the light in place while also allowing it to move up and down for as your plants grow in height. Using several short self-tapping screws, I attached the L bracket to the PVC tube, and then I fastened the hanging clip from the SunSeeker Lights to the L bracket. The hanging mechanism of most T5 lights is very similar. Then I attached the lights to the ceiling using clips and plugged them in.

Step 5: Finishing Touches

I attached some velcro tabs at one end of the bag so that I can simply unzip it and see the contents within. When the lights are turned on inside, the temperature rises to 24-25 degrees Celsius, which is about the ideal temperature for germination and developing seeds. As a result, no light is lost, and the soil will not dry up as quickly as it would have due to the enclosure. I intend to install a temperature switch that will activate a small computer fan that will ventilate the inside if the temperature rises too high, preventing my plants from being fried.

However, when the winter season draws to a close and the basement begins to warm, the situation may change.

Even though starting seeds indoors may appear to be a difficult task, this tutorial will walk you through the procedure step by step, including troubleshooting techniques to make it simple.

Why Start Seeds Indoors?

  • Get a start on the gardening season. Although starting seeds inside is necessary for northern gardeners who wish to produce warm-weather crops such as tomatoes, many plants flourish better when transplanted into the garden. Conserve your funds! Growing your own seedlings can be more cost effective than purchasing plants if you want to develop a large garden, especially if you utilize recycled containers and homemade seed starting mix. Plants that are in good health. Some garden centers have handled their plants in such a way that I’m sure I’m not the only one who has felt terrible for them. When you start seedlings from seed, you have the opportunity to provide them with lots of attention. Increase your access to a wider range of options. Why limit yourself to growing simply russet potatoes when you can also produce purple, yellow, and red potatoes? It is pointless to cultivate just red, tennis ball-shaped tomato plants when you can grow ones that are pink or purple or green-striped or yellow or orange or white or even turban-shaped or sausage-shaped? There are literally thousands of varieties to choose from! If you’re seeking for ideas on where to buy seeds, you can look at my preferred seed sources

1. Plan Your Plantings, Label and Keep Records

Decide what you want to produce and when you want to sow seeds inside, taking into consideration your last frost date. See ourPrintable Seed Starting Calendarfor a list of which plants to start indoors and which to direct seed in the garden. When seeds are labeled “direct sow,” it is typically advisable to put them directly in the garden. The varieties planted, the day they were planted, when they first appeared as seedlings, and other basic details are all recorded in a simple spreadsheet I maintain.

Make a note of your seedlings!

It’s remarkable how similar garden plants may appear when they’re at their smallest.

2. Choose the Right Seed Starting Soil Mix

Potting mix should be rather light, but it should still be able to contain enough water to keep seedlings well-watered. FoxFarm organic potting soil is the potting soil that I am now using.

Earthworm castings, bat guano, and seagoing fish and crab meal are among the ingredients in this composted forest humus, sandy loam, and sphagnum peat mix. If you want to manufacture your own potting mix for beginning seedlings inside, use one-third each of the following ingredients:

  • Potting mix should be rather light, but it should still be able to contain enough water to keep seedlings wet during the growing season. FoxFarm organic potting soil is the potting soil that I’m now using as a centerpiece in my garden. Earthworm castings, bat guano, and seagoing fish and crab meal are among the ingredients in this composted forest humus, sandy loam, sphagnum peat mixture. Using one-third of the following ingredients, you may prepare your own potting mix for indoor seed starting:

To prevent soil illnesses, heat your soil or compost to 180 degrees Fahrenheit (82 degrees Celsius) in an oven at a low temperature for 30 minutes and then allow it to cool. It is not necessary to pasteurize compost or soil if they are in good condition. Overheating the soil can be detrimental, so proceed with caution.

Can you use garden soil for starting seeds indoors?

It is not something I would suggest. Because plain soil does not drain well enough, seeds will rot and seedlings will be more prone to fungus issues in the future. You could potentially bring weed seeds or illnesses from your garden into the environment.

3. Choose the Right Seed Starting Containers

My seeds are started in old cell packs or other repurposed nursery pots for the most part. My friends know that I start seeds inside (sometimes I sell or trade my surplus plants), so they keep their pots for me. Repurposing old pots is my preferred method of growing plants since they are robust, have drainage holes, and fit nicely into the huge seedling trays. A lot of the concepts for handmade pots I’ve seen are either too little (like eggshells) or too fragile in my opinion (like newspapers).

  • No matter which option you pick, make sure your pots drain adequately and/or that you are careful not to overwater them.
  • When it comes to seedlings, deli containers are OK as long as you do not put them in standing water.
  • A lot of the time, I plant seedlings straight in the garden from 1 inch cells, but I also “pot up” seedlings indoors on occasion.
  • More information on this may be found in the blog article “How to Grow Tomatoes from Seed “.

4. Provide Plenty of Light

Keep in mind that while you are beginning seeds inside, your plants will need 16 to 18 hours of light every day. Turn off the grow lights at night so that they may get some sleep. (Growing plants require rest as well!) Plants thrive when the lights are maintained near to them, around 3-4 inches over the seedlings’ heads. Lighting your plants with LEDs or fluorescent lights allows you to retain light near to the plants while avoiding scorching the tender seedlings. I use a simple plugin timer to switch on and off our grow lights throughout the day.

As a result, they are tall and floppy.

You may get the seed rack plans from this website.

Do you need special plant lights to start seeds indoors?

Plant lights are fantastic if you want to make the expenditure, but they aren’t required in all situations. Initial experiments were conducted with “plant bulbs” in fluorescent shop lights, and I have recently switched over to LED grow lights.

Our first attempt employed LED shop lights, which worked well while the plants were little but resulted in some leaf yellowing as the plants became larger. Here is where you may get LED grow lights.

5. Keep Indoor Seeds and Seedlings at the Right Temperature

A little warmth will aid in the germination of your seedlings. I’ve placed seedling trays near the wood burner or on top of the refrigerator to provide easy access to them. Starting the heat at the same time is easy since you don’t have to move your trays all around the home. Check see the influence of soil temperature on sowed seeds for a more in-depth comparison of germination rates at a variety of different temperatures. Once seeds germinate, the majority of them thrive in temperatures ranging from 60 to 70 degrees Fahrenheit (15 to 21 degrees Celsius).

6. Cover Seed Trays to Improve Germination

When your seeds are germinating, a little warmth can assist. Several times, I’ve placed seedling trays near the wood burner or on the refrigerator’s top shelf. Because you don’t have to move your trays about the home, starting the heat from the beginning is convenient. Check out the influence of soil temperature on sowed seeds for a full comparison of germination rates at different temperatures. At 60-70 degrees Fahrenheit (15-21 degrees Celsius), most seeds germinate and thrive happily for a period of time.

7. Plant Seeds at the Right Depth

When planting seeds, use this rule of thumb: Plant seeds approximately three times as deep as the diameter of the seed. Although precise directions should be included on seed packs, this is a good general rule to follow. Some seeds require sunshine in order to germinate, thus they should be placed on the surface or only very gently covered when they are planted on the surface.

8. Provide Enough Water to Seedlings, but Not Too Much

While the moisture content of your indoor seed starting mix should be moist enough that it holds together when you squeeze a handful, it should not be so wet that water drains out when you compress it. Covering the pans with plastic wrap should be sufficient to keep them damp until the seedlings germinate. Once your seedlings have begun to develop, you should water them lightly every few days. (Warmrainwater is excellent if you have access to it.) I allow the soil to dry to a certain extent between waterings, but not totally.

Moss, fungal development, and seedlings that fall over dead due to a poor foundation (damping off) are all indicators of too much water being applied.

9. Provide Good Air Circulation and Movement

It’s possible that you’ve observed huge fans installed in commercial greenhouses. These fans circulate air, which helps to keep foliage dry and prevent fungal infections from developing. They also aid in the strengthening of the plant stems, which are necessary since the seedlings must maintain their erect position in the gentle breeze. If you have a limited number of seedlings, gently brushing the plants many times each day might help strengthen the stems.

A fan is significantly more convenient when dealing with a large number of seedlings (such as several dozen or more). In addition to the lights, we maintain a standing fan running on the same timer and have it oscillate across the seedling trays.

10. Feed and Care for the Young Seedlings

When it comes to providing nutrients to seedlings, foliar feeds such as liquid seaweed fertilizer are a favorite of mine. Compost tea and worm poo tea are two more excellent gentle feeding choices to consider. EM-1 Microbial Inoculantis is a bacterial inoculant that is introduced to water in order to introduce helpful bacteria to the soil. If seedlings get overcrowded, they should be transplanted to larger pots or moved to the garden. If you have more than one seedling in a container, you may either transplant them to individual containers or use a pair of scissors to snip off all except the healthiest seedlings at the base of the container.

11. Harden Off Seedlings Before You Plant Outdoors

Plants that have been started indoors must be allowed to gradually adapt to outside circumstances before being transplanted to the garden. This is referred to as “hardening off.” Place seedlings outside in a sheltered spot, out of direct sunlight, as soon as the time for transplanting is approaching. Start by spending a couple of hours outside each day, and gradually increase the amount of time you spend outside. They should be ready to plant in the garden within three to five days of being harvested.

Special Considerations for Starting Seeds Indoors

Seeds are subjected to a preliminary treatment. Some seeds, particularly wildflower seeds, require stratification (freezing before planting) before they may be planted. Scarification may be beneficial for seeds that have robust outer hulls (cutting or weakening the covering of the seed). Certain seeds should be soaked prior to planting. If you’re working with a plant that’s unfamiliar to you, double-check the precise planting guidelines. Most plants do better when they are young and can be transplanted.

Transplant shock is often less severe in most plants, especially when they are placed into the garden before their roots begin to loop around the sides of their pots.

Our Indoor Seed Starting Setup

Our basement was planned to be utilized as an apartment for aging parents, which is why I have a kitchenette between my root cellar and the door to the adjoining greenhouse, which is convenient for entertaining. Because we do not have any other housemates at the moment, this is my gardening space. I’ve got enough of water on hand, and my mess has been kept under control. Once the seeds have been planted in the planting pots by the sink, I put up seedling trays on my seed starting shelves to grow them into young plants.

Afterwards, they should be moved to a cold frame or other semi-protected location to harden off before being moved to the garden. If you have any special queries regarding beginning seeds, please do not hesitate to contact me and I will see if I can assist you.

How to Start Seeds – Germinating Seeds

Seeds may be started in a variety of methods, but using a seed-starting system, such as theGrowEase Seed Starting Kit, assures successful outcomes.

Keep it Simple

Growing plants from seed is an excellent method to get a head start on your gardening season early in the season. It is straightforward to cultivate plants from seed to harvest if you have access to enough lighting and basic equipment. Because each plant has its own set of seed-starting needs, it is best to start small by cultivating only a few different types of the same species. Seeds such as tomatoes and marigolds, for example, are very simple to grow from seed inside. Basil, zinnia, coleus, nasturtium, and cosmos are other excellent alternatives for first-time gardeners.

Marigolds blooming amongst the produce

Seven Steps, from Seed to Garden

  • When it comes to seed starting, the aim is to have your seedlings ready to transplant outside as soon as the weather conditions are right. Look at the seed packet to determine when to start the seeds inside
  • This should be indicated on the packet. Typically, it will read something along the lines of “Plant indoors six to eight weeks before last frost” or something similar. Some crops, such as beans and squash, are better started outside because of the weather. Because they germinate and develop swiftly, there is little advantage to growing them inside. Some flowers, such as poppies, flourish best when they are planted outside as well. “Direct sow” seeds are those that are labeled as such.

Find the right containers

  • As long as the container is at least 2-3 inches deep and has some drainage holes, you may start seeds in nearly any sort of container. If you want to do things yourself, you may consider growing seedlings in yogurt containers, milk cartons, or paper cups. I appreciate the ease of seed starting trays that are specifically designed for this purpose. It’s simple to fill the trays, and the watering mechanism guarantees that they remain consistently wet. I can also transfer them effortlessly.

Prepare the potting soil

  • Select potting soil that has been specifically designed for the growth of seedlings. You should not use soil from your garden or potting soil from your houseplants for this project. Begin with a fresh, sterile mix that will guarantee that your seedlings are healthy and disease-free. Before filling your pots, wet the planting mix in a pail or tub before placing it in the containers. When you make crumble, you want it to be moist but not soggy
  • Crumbly but not gloppy. Fill the pots with dirt and compact it tightly to prevent any gaps from forming. You should keep in mind that most seed mixes are deficient in nutrients, so you’ll need to feed your seedlings with liquid fertilizer for the first few weeks after they germinate, and then every few weeks until you transplant them into the garden.

Start Planting

  • In order to determine how deep you should plant your seeds, see the seed packaging. It is possible to sprinkle some of the smaller ones straight on top of the soil surface. Larger seeds will need to be buried for a longer period of time. I sow two seeds each cell as a precautionary measure (or pot). If both seeds germinate, I will clip one and allow the other to grow until it is fully mature. It’s a good idea to make a couple of divots in each pot to allow for the seeds to grow. Having placed a seed in each divot, you may now go back and cover the seeds with soil. Use a mister or a small watering can to wet the seeds once they have been placed. Cover the pots with plastic wrap or a plastic dome that fits over the seed-starting tray to help the seeds germinate more quickly. This will assist in keeping the seeds wet until they germinate. Remove the cover as soon as you notice the first symptoms of green growth.

Water, feed, repeat

  • In order to determine how deep you should plant your seeds, check the seed packets first. It is possible to sprinkle some of the smaller ones directly on top of the soil surface. Those with larger seeds will need to be buried for a longer period of time. I place two seeds in each cell as a precaution (or pot). Alternatively, if both seeds germinate, I clip one and let the other to continue to develop. For the sake of the seeds, it is beneficial to make a couple of divots in the bottom of each pot. Having placed a seed in each divot, you may now go back and cover the seeds with dirt. Use a mister or a small watering can to sprinkle the newly planted seeds before they take root. Using plastic wrap or a plastic dome that fits over the seed-starting tray will help to expedite germination and increase the likelihood of success. Prior to germinating, this helps to keep the seeds wet. Remove the lid as soon as you notice the first indications of green.

Light, light, light!

  • Seedlings require a great deal of light. If you’re growing in a window, make sure it has a south-facing orientation. Plants should be rotated in their pots on a regular basis to avoid them leaning into the light. Seedlings will become leggy and feeble if they do not receive enough sunlight. You should set your lights so that they are just a few inches over the tops of your seedlings, if you’re growing them under lights. Set the lights on a timer for 15 hours a day to save energy. Keep in mind that seedlings require darkness as well, in order for them to relax. Increase the intensity of the lights as the seedlings develop in height.

Move seedlings outdoors gradually

  1. It is not a good idea to transplant your seedlings immediately into the garden from their sheltered surroundings in your house. Given that you’ve been caring for these seedlings for several weeks, they require a cautious introduction to the vast outside. Hardening off is the term used to describe this phenomenon. Place the seedlings in a sheltered position outside (partly shaded, out of the wind) for a few hours each day, bringing them in at night. This should be done about a week before you want to plant them in the garden. Gradually expose them to more and more sunlight and wind over the course of a week or ten days, increasing their exposure time. A cold frame is an excellent location for hardening off plants.


There are a variety of elements that influence the germination of seeds. Check the seed packaging to ensure if all of the requirements for temperature and light were satisfied before planting the seeds. It is possible that the seeds rotted because the soil was too cold and too moist. Take one of the seeds out of the ground and inspect it. If the seed is bloated and squishy, it means the seed has perished and you will have to start from scratch. If the soil was too dry, the seeds may not have germinated or they may have dried up before their roots had a chance to establish themselves.

Try again, but this time be sure to use constant wetness.

My seedlings are spindly. What can I do?

When plants do not receive enough light, they become tall and lanky in appearance. Grow lights should be used to guarantee that they receive 15 hours of strong light every day on a consistent basis. Warm temperatures can also encourage the development of leggy growth. Reduce the temperature of the room and the amount of fertilizer you use to see whether you can get away with it. More information about this issue may be found in the article Growing Under Lights. According to ourGarden Lab: The seedlings on the right were started on a windowsill and allowed to flourish.

On the left, you can see seedlings that have been cultivated under lights.

The leaves on my tomatoes are starting to look purple along the veins and on the underside of the leaves. What’s happening?

A plant’s purple leaves are an indicator that it is not getting enough phosphorus from the soil. If you have been feeding your seedlings with half-strength fertilizer for the first three to four weeks of their lives, it may be time to switch to full-strength fertilizer. A minimum of 3 phosphorus should be present in the fertilizer analysis (the middle value on the fertilizer analysis).

My seedlings were growing well until all of a sudden they toppled over at the base. What happened?

It is most likely that a soil-borne fungus known as “damping off” is responsible for the death of immature seedlings whose stems have grown withered and have fallen over.

The presence of this fungus in the soil is difficult to eliminate, but it may be avoided by utilizing a sterile, soilless growth media and by ensuring adequate air circulation in the growing environment.

Mold is growing on the top of the soil surface. It doesn’t appear to be hurting my plants, but should I be concerned?

Answers to frequently asked questions about starting seeds indoors

A seed-starting kit, such as theGrowEase Seed Starter Kit, makes it simple to produce strong, healthy seedlings from the seeds you’ve planted. I’ve spoken with a plethora of gardeners who are adept at growing plants outside but are apprehensive about starting seeds from seed indoors. One of the most satisfying aspects of gardening for me is the process of beginning seeds. During the dark, chilly days of late winter and early spring, it allows me to get my hands in the dirt (or at the very least the seed-starting mix).

Here are some of the hundreds of questions I’ve received concerning seed starting, as well as my responses to them.

From a single package of seeds, you may grow a dozen or more plants.

Why start seeds indoors?

Gardeners start their own seeds for all sorts of reasons. For starters, by starting your own seeds, you will be able to grow kinds that are otherwise difficult to get. In your local garden center, you’ll likely find less than a dozen different types available as plants; but, hundreds of different varieties are accessible as seeds. Saving money is another advantage; a packet of seeds costs a few dollars and typically contains a dozen or more seeds — one plant, on the other hand, is sometimes more expensive than the entire packet.

What seeds are easiest to start indoors?

If you’re new to seed starting, start with simple, dependable seeds such as tomato, pepper, basil, zinnia, marigold, and cosmos, which are all easy to grow. All of them germinate and grow swiftly after they are planted. Once you’ve mastered them, you may go on to more difficult plants to learn how to grow. Sowing instructions are usually included with most seed packs.

When should I sow my seeds?

It is imperative that you start seeds indoors at the correct time of year. To do this, seedlings should be grown to the appropriate size for transplantation into the garden at the appropriate time. Sowing dates are determined by the following factors:

  • Last spring’s average frost date
  • If the plant favors cool or warm growth circumstances
  • How rapidly the seed germinates and develops
  • And how quickly the plant matures.

Planting times are usually included on seed packs, such as “sow seeds inside six weeks before your typical last frost date,” or similar language.

To determine your planting date, begin by establishing your average last spring frost date, marking it on a calendar, and then counting backwards in one-week increments from there. Create a planting calendar by starting at the date of your last frost and counting backwards.

How do I know my last frost date in spring?

Asking a neighbor who is an experienced gardener or asking employees at your local garden shop is the quickest and most efficient approach to find out. You may also visitThe Old Farmer’s Almanacwebsite or discover aMaster Gardenerprogram (part of your state’s Cooperative Extension). Given that the exact date of the last spring frost changes from season to season, the “average last spring frost date” is only a rough approximation, but it serves as a good starting point for planning. These seedlings, growing on a windowsill, are seeking for the sun despite their gloomy appearance.

Can I grow on a windowsill or do I need special grow lights?

Growing seedlings on a sunny windowsill is conceivable, but you’ll get far better results if you grow them in a fluorescent light system. This is due to the fact that the sunshine in early spring is not nearly as bright as the sunlight in summer, and the days are also shorter. Seedlings growing on a windowsill will strive towards the sunlight, resulting in long, brittle stems that bend in the direction of the sun. On the other hand, plants grown under the continuous, bright fluorescent lights of a light garden will develop sturdy stems that will adapt better to their new environment after they are transplanted into the garden.

Can I use garden soil to start seeds?

Garden soil has a low ability to drain, which is especially true when it is utilized in small seed-starting trays. It can also host disease organisms, which can cause harm or death to young seedlings if they are not protected. If you start seeds in a mix that has been specifically designed for beginning seeds inside, such as our exclusiveOrganic Seed Starting Mix, you’ll receive the greatest results. Seed-starting systems are created to promote the development of healthy seedlings.

What type of pot should I use?

Although you may start seeds in any container with drainage holes, seed-starting pots and trays that are specifically made for this purpose produce the best results. They allow you to start a large number of seeds in a little amount of area, and they allow for free drainage to prevent rot. Some individuals prefer biodegradable pots, while others prefer reusable trays or trays that can be washed. Self-watering, all-in-one seed-starting systems are simple to use and almost failsafe. Seed Starters are available for purchase.

How deeply do I plant the seeds?

The majority of seed packs specify how deep to put the seeds. As a general guideline, sow seeds two or three times as deep as they are broad, depending on the variety. Take care not to bury the seeds too far into the ground. A seed carries a finite amount of food that will be used to sustain the seed during germination. In the event that you plant it too deep, it will run out of food before it reaches the light and grows large enough to begin creating its own food.

Some seeds, such as sunflower seeds, require light to germinate; the seed packaging should specify this. These seeds should be sown on the surface of the planting mix. Self-watering seed starts eliminate the need for guessing when it comes to watering.

Which is better, watering from the top or from the bottom?

Lower soil moisture levels are normally better since they keep the soil surface drier, which aids in the prevention of disease issues. Top misting tiny seeds or seeds that have been surface-sown will help to improve germination by keeping the surface wet. Self-watering seed-starting systems, such as ourGrowEase Seed Starter Kit, rely on a wicking cloth to draw water from the bottom of the container, ensuring that plant roots receive a consistent supply of precisely the proper quantity of water.

As soon as you notice the first sprouts, remove the cover from the greenhouse.

When do I remove the greenhouse cover on my seed starter?

The greenhouse cover retains moisture, increasing the humidity and allowing for faster germination of seeds. Remove the cover as soon as you notice the first small sprout appear. This permits air to circulate around the seedlings, reducing the likelihood of disease outbreaks. Maintain a height of 4 to 6 inches above the seedlings.

How close should the grow lights be to the seedlings?

Make sure the lights are only a few inches over the tops of the seedlings in order to encourage robust, stocky development. We have adjustable lights built into our grow light stands that are simple to elevate as the seedlings develop. The use of a seed starting timer makes it simple to provide seedlings with the appropriate quantity of light.

Do I leave the lights on all the time?

The majority of seedlings develop best while the lights are on for around 14 to 16 hours every day. In order to prepare for active development when the lights are turned back on, they require a time of darkness (like they would in the natural world). This is made simple by the use of an automated timer. Seedlings should be thinned to one per cell.

Do I need to thin my seedlings?

After a few weeks of growth, it is possible that seeds may begin to crowd one another. It will be necessary to thin the seedlings after this has occurred. For most gardeners, this is the most difficult step in the seed-starting process. Selecting the strongest seedling and eliminating the weaker ones from the surrounding area. This provides more growing space for the remaining seedlings. Although you can try to separate seedlings and transplant them, you will almost always injure part of the roots, which will cause the growth to be stunted.

The “true leaves” of the plant are similar in appearance to the mature leaves of the plant.

When should I start fertilizing my seedlings

The initial set of leaf-like structures isn’t actually leaves at all, but rather the seed’s food storage structures, which are referred to as cotyledons (or seed leaves). The second and succeeding sets of leaves are real leaves, and they are similar in appearance to the leaves of a mature plant. Fertilize seedlings when they are an inch or two tall, or when they have their second set of true leaves, depending on their stage of development. It’s time to transplant – before the roots become too tangled together.

How do I know when it’s time to transplant into larger pots?

Tomatoes and other fast-growing plants may overrun their pots before they are ready to be transplanted into a permanent location in the garden. Remove one of the seedlings from its pot gently about a month after sowing, or when the seedlings are about 4″ tall, depending on when you started. If the roots are beginning to encroach on the surface of the pot, it is time to move them to a larger container or container. Don’t leave it too long, because root crowding will slow down the growth of the plant and make it difficult for the plant to recover after transplanting.

Our Pop Out Pots make excellent transplant containers. Prepare seedlings for planting in the garden by allowing them to become acclimated to the environment.

What is “hardening off” and how do I do it?

Simply said, hardening off is the process of acclimatizing plants to outside circumstances. Seedlings that have been raised inside have been spoiled rotten – you’ve been providing them with the perfect quantity of light, water, and nutrients. Outdoor settings are more difficult to deal with because of the shifting temperatures and light levels, as well as the more changeable soil moisture and the wind. Prepare the seedlings by hardening them off about a week before you want to transplant them into the garden.

Gradually expose them to more and more sunlight and wind over the course of a week or ten days, increasing their exposure time.

What Went Wrong?

Even the most seasoned seed starters have difficulties from time to time. Here are some signs and symptoms, as well as some potential reasons. The germination was poor. Despite the fact that the majority of popular vegetables and annual flowers sprout easy, some species of plants are infamously difficult to germinate. In many cases, this is clearly stated on the seed packaging (with the suggestion to sow extra seed). First and foremost, be certain that you have given them enough time to germinate.

  • Some seeds take up to two weeks to sprout, while others take as long as three weeks.
  • (The latter problem may be solved by using aHeat Mat.) If the soil was too dry, it’s possible that the seeds were unable to absorb enough moisture to germinate and grow.
  • A lack of germination can also be caused by seed that is past its expiration date or seed that has not been properly kept.
  • It’s likely that you’re experiencing the impacts of damping off if, after a few days, several of your seedlings droop over as if a little lumberjack had felled them at the soil line.
  • There is no treatment, and the seeds will not reseed themselves.
  • In order to ensure proper air circulation, let the soil surface to dry out somewhat between waterings and install a fan in the room.
  • It’s time to turn the volume down.

In the case of mold or algae, you’ll see fuzzy white growth and slimy green areas on the surface of the planting mix or the exterior of biodegradable containers.

To promote air circulation, allow the plant to dry out somewhat between waterings and use a modest fan in the room.

Seedlings that are “leggy” are frequently the result of insufficient light, both in terms of intensity and duration.

They should be kept on for around 14 to 16 hours every day.

Inadequate fertilization might result in plants that are pale and have weak stems.

It is possible that the plants require a nutritional boost if the seedling foliage is pale green, yellowish green, or has a purple hue to it.

Make use of a water-soluble fertilizer that has been diluted to half its original strength, and apply it once a week for the first few weeks.

After that, you may work your way up to applying full dosage on a weekly basis. (Make certain to adhere to the dilution rates specified on the label.) The most recent update was made on January 3, 2022.
