What Size Led Light For 4X8 Grow Tent

What size LED light for 4×8 grow tent?

Comments received on August 14, 20200 The technique of determining the size of your LED light is essentially a two-step procedure. First, you must determine the amount of the grow area available, and then you must determine the canopy dimension. People frequently inquire as to how many watts are required for a 4 x 8 grow tent. Keep your eyes peeled for the solution, which will be revealed below! During the FLOWERING STAGET time period You will require an LED light with an output of at least 50W per square foot of growing space in order to achieve a positive yield throughout the flowering season.

This results in a square foot grow space of (4ft x 8ft) = 32 square feet.

The LEDcannabis grow lightbulb size for your 4 x 8 grow tent must be at least 1600W, or you can use a mix of numerous LED grow lights totalling 1600W in order to meet the requirements.

In layman’s terms, if you need 1600W during the blossoming stage, you will require (1600 x 2)W = 800W during the vegetative period.

So, how do you decide which LED grow light to purchase?

Thoughts of the Final Hour

It’s quite normal to feel a little disoriented when faced with the plethora of enticing options available on the market. And believe us when we say that it occurred to us in our early days as well! A team of researchers spent many days conducting thorough study to discover the ideal led light for a 48 grow tent. As for lighting up your expanding tent, maybe you will choose the “smarter” option this time. Take your time, read the reviews, and compare the goods you’re interested in. Here’s to a successful harvest season for you!

LED lights for 8×4 grow tent

There are a variety of alternatives. There are too many possibilities to cover them all. Two HLG550s ($750 each) would probably be the most secure and reasonably cost option, with the possibility of adding some extra illumination when you add CO2. A few individuals have praised the Growers Choice ROI light that Anthem mentioned above; my local grow store has these, and they have received positive feedback from others. The issue I have is that if I’m going to spend $1000 on an unknown brand, why not simply purchase the Fluence Spydr 2p or 2i for $250-$450 more and save money in the process?

Either of these lights, as well as many other large bar-style lights, would be excellent choices for CO2.

If you don’t want to spend the money on Fluence but can spare $800-$1000 per light, the decision between HLG and a bar-style Fluence clone like the ROI becomes more difficult.

In order to spend even less, the alternatives become more limited, since most cheaper lights either cannot be used with CO2 or would need the purchase of several lights, which would result in a cost similar to or larger than the higher-end lights.

Please feel free to elaborate on your requirements; myself and the other members of this forum would be pleased to attempt to assist you.

Which LED lights for 4×8 Flowering Tent?

  1. Date of joining: September 3, 2017 Messages:24 Likes Received:2 Hello, I was wondering what you would recommend for LED grow light setups when it comes to cannabis cultivation. I was planning on purchasing two Advanced Platinum LED P1200 lights, however the reviews state that they are not suitable for tents due to their weight. I was also considering if it would be excessive to purchase two given the space available in a 4×8 tent. When it comes to LED lights, which ones do you recommend for a 4×8 tent with an unlimited budget? The reviews I’ve read on the Platinum LED lights indicate that they have a high failure rate. If I had an unlimited budget, I would invest in a cob setup. Is there a specific amount of money you’d want to spend on a led? We can provide a recommendation. The fact that something costs more does not imply that it will perform better.

I built up a 4 x 8 grow room for a customer using those lights about 6 months ago, and I can tell without a doubt that vertical lighting with Kind lights produces gorgeous plants with amazing resin production if you want to grow the greatest plants possible under LED lighting. Oh, and the greatest part is that they truly stand by their lights with their whole hearts and minds. If you have an issue, they will take care of it immediately and without hesitation! They manufacture lights that are vertical or above the head! In passing, I’d like to mention I have never been a fan of anything LED or COB
  • For me, it has always been and will continue to be HID lighting. And that’s just because HID continues to grow the greatest bud in my opinion. Yeah, I’ve tested well over two hundred various LED(s) and COB(s), and none of them can match the results I obtain with HID and inexpensive $8.00 1K sylvania lights watt for watt. For the avoidance of doubt, I have nothing against anyone using whatever they choose
  • I simply prefer HID lighting since it works so well for me

I like it, however there are nicer leds on the market now that are less expensive. To blossom with platinums throughout the full 4×8 space, the optimum plan would be four platinum p600s placed side by side. I have a p900, which isn’t too hefty for a tent to carry. The gorilla tents have a capacity of p1200. In addition, I grow in a 4×8 that has been divided in half.

You may make them more evenly distributed and spaced further apart. A p1200 is identical to two p600s that have been taped together. In the same way that a p900 is made up of two p450s. Having said that, I’ve been using platinums in my floral area for the past two years without incident.

Using decent potency, I’ve been able to achieve up to about.8 grams per watt, however technology in led grow lights has advanced really rapidly.

The qb 260 kits that I provided you with are exactly what I purchased to replace my platinums.

I feel awful for criticizing them because they did provide me with some excellent cannabis, but times have changed. I wouldn’t spend the money on them right now. This is a 270 watt qb260 operating next to a 515 watt platinum p900 in a close proximity.

I would suggest a couple of clips on 6 “There are fans for each light to assist cool them and circulate exhaust fan air, as well as a huge exhaust fan configuration. 8 is a possibility “. These creatures are capable of producing the illumination of a 1000 watt high-pressure sodium lamp individually. They create some heat and do not have ventilated hoods to help cool them down. I’ve definitely had issues keeping my QB260s cool while they’re running at full throttle. Because they produce so much light, it is inevitable that some heat will be generated.

1200 or 1800 watts for a 4X8 grow tent?

You are currently using an out-of-date web browser. It is possible that this or other websites will not show correctly. You need either upgrade your browser or switch to another one. Okay, so I’m getting ready to start my first indoor grow. I’ve already visited three local hydroponics stores, visited a million websites, and read Cervante’s bible from cover to cover. I know, I’m a typical rookie, but bear with me. I’ll start with a simple veg and flower tent (4x8x6.5 tall, $189 plus shipping and tax) to see how things go.

  • Growing in the dark is no longer an option with the 100 percent reflective Mylar Hydroponics Grow Tent, Non Toxic Hydro Dark Room Box from Amazon.com “The GYO1011: Patio, Lawn, and Garden Hut is 96 inches by 48 inches by 78 inches.
  • I’m completely baffled.
  • Question 1: Should I use two 600-watt MH/HPS lights or three 600-watt MH/HPS lights for a 32-square-foot area?
  • I have some money put aside for my setup and am willing to add a third 600 watt power supply if absolutely necessary.
  • Question 2: Will I require air conditioning if I use two or three 600-watt bulbs in a mylar grow tent?
  • What do you think is the best course of action?
  • Question 3: I’m trying to decide between soil and hydro.

Please accept my heartfelt appreciation in advance.

Do you mean 4×8 if you’re talking about 8 feet tall?

If this is the case, two lights should be plenty, especially at 600 watts.

If you are going to use three lights, you may wish to use 400 watt bulbs.

The reading material is extensive, but if you put in the effort, you will save yourself a great deal of trouble.

Reading the lumens and other such material is actually overkill for me at this point.

I’m curious as to what the temperature is in the basement.

Because if it’s too cold, you should opt for an air-cooled light housing.

I decided on the Hydro gro because of the ease with which the nutrients could be mixed and the lack of mess.

Depending on how you set it up, I believe there is significantly less mess.

I’m not sure how many lumens are produced by each plant, though.

I believe that the plant will thrive with only CFLs, and therefore, any HID bulb will, in my opinion, be a complete waste of time.

I wish I had first.

Great luck to you!

My basement is pretty much 55 degrees (winter low) to 75 degrees (summer high) (summer high).

We have -10 degree days here in CO and 100 degree days, too.

I think one thing I want to do is to set up a $20 remote thermometer down there and keep track of the temp.

So the formula looks like this: 250W HID = 2′ X 2′ area (200W min) (200W min) 400W HID = 3′ X 3′ area (450W min) (450W min) 600W HID = 3.5′ X 3.5′ area (612.5W min) (612.5W min) 1kW HID = 4′ X 4′ area (800W min) (800W min) So according to my calculations of your 4′ X 8′ area, you will need 1600 watts.

  • you could do that in a few combinations I’m sure.
  • Some lamps give more lumens than others.
  • But 2500 lumens is bare minimum per plant and I am sure you will stay way clear of that.
  • Would love to see what you decide to do when you got it all set up.

beware of high humidity though while lights off. You can get 30 plants easy and makes no dif. soil or hydro for lighting. 2 600 watterswd. be all ya need for that foot print especially since ya can hold them closer to the plants 1000 wd need to be set high up

Another point that I only lately realized was important. On Mondays, I also run 1K’s without the use of active air conditioning. As long as the mover is in place, you can pretty much let them grow into the lamp; but, when I install a blower on a 1K that does not have a mover, I have to keep around 16″ away. Not because of the heat (since the housing is cool), but because of the intense light wash. The intensity is concentrated in a single location. If you have a ceiling height of 7 feet, you’re good.

  • He would tell you the same thing he would tell me.
  • Isn’t it true that if I receive an extra 2 oz by having three 600W bulbs, it will more than pay for itself?
  • I’m now working on building a clone room and a mother room in my basement, which is located beneath my stairs.

Will there be a drop in yield?


1k provides 31 watts per square foot of space. According to what I’ve read, movers boost efficiency by 40%. (I’m not sure whether that’s a reasonable expectation, but that’s what they say.) You get 43w sq/ft by multiplying 31w by 1.40. I’d just hang another 1000 on the wall. 1k provides 31 watts per square foot of space. According to what I’ve read, movers boost efficiency by 40%.

versus one who is moving?

Curiosity got the better of me.

Lumens are a bunch of nonsense, and they don’t signify anything. A 4×4 area is covered by 600 watts. It is entirely up to you whether or not you can deal with the heat buildup inside the tent.

How Many LED Watts Are Required Per Square Foot of Grow Space?

*This article was last updated in May 2018. Are you a newcomer to the world of LED cultivation? If this is the case, the charts below will assist you in determining how much energy (measured in watts) your plants require to blossom. Disclaimer: Wattage is a legacy of the days of high-intensity discharge (HID) lamps (MH and HPS). The coverage area of a fixture or the utility of an LED grow light should not be determined by the wattage of the fixture or the LED grow light. Using wattage as a simple technique of estimating the optimal fixture size for your grow should be limited to the most basic of situations.

PPFD (and spectrum) are essential components of a good grow when used in conjunction with the appropriate spectrum for your plant type and development phase.

The term “wattage” in this article refers to the amount of electricity that is pulled from the wall, not to the amount of electricity that is drawn from the LEDs, which is normally the product of the maximum LED wattage multiplied by the number of LEDs specified by the manufacturer.

The LED grow light, on the other hand, may only consume 500 watts when connected to the wall.

Grow variables

It is critical to note that the amount of actual watts that you will use for your grow will vary based on the following factors:

  • Plants that require a lot of light, such as tomatoes, peppers, and other vegetables
  • Plants that require little light, such as herbs and leafy greens (such as basil lettuce)
  • There is a significant difference in the quantity of light required by seedlings, vegetative, and blooming plants.

Watts per square foot

For flowering, the average LED grow light consumes approximately 32 watts to cover 1 square foot. This is in stark contrast to a conventional HID lamp, which consumes 40 watts per square foot (assuming a 5′ x 5′ space or a coverage area of 25 square feet). The use of a HID in a 4′ x 4′ area will increase the power coverage to 62.5 watts per square foot (psf). (The energy savings that growers may expect from employing LED grow lights instead of high-intensity discharge lights is around 38 percent.) This energy savings figure solely includes the savings that farmers realize as a result of utilizing LED lighting fixtures.

For example, depending on the size of the setup and the temperature of the surrounding environment, less ventilation and air conditioning may be employed, or it may be altogether avoided.

More energy-efficient LED grow lights will consume fewer watts to produce the same amount of light that a less energy-efficient LED grow light would provide.

As a result, as previously said, wattage is not the most accurate tool for determining how strong of a grow light you require for a specific coverage area under consideration.

LED Wattage Chart Explanation

The wattages indicated below are based on the assumption that you are blooming your plants. If you’re growing vegetables, you might want to consider reducing your wattage by 50% because vegging plants only require roughly half the amount of light that flowering plants do. As is always the case, following the manufacturer’s advice is the best course of action.

Using the charts

The following columns will be included in each of the charts:

  • Plants to be cultivated in a certain area The area covered by a certain number of plants in terms of square footage
  • The recommended LED wattage is based on the quantity of plants being grown in the given space.

Wattage charts

For blooming, assume a wattage of around 32 watts per square foot (real LED wattage). Smaller yields may be associated with lower wattage, whereas bigger yields may be associated with higher wattage.

Related:What is the difference between PAR, PPF, DLI, and Efficacy? It is important to understand the light factors that affect your indoor plants. See what else you should think about before choosing an LED grow light in this article. Please keep in mind that the growing of some plants may or may not be permitted in your individual region or nation, depending on the laws in place. LED Grow Lights Depot does not advocate or condone any unlawful conduct, and we urge each person / user to become familiar with the applicable laws in their own region or nation before engaging in it.

Choose the Right LED Grow Light Based on Your Grow Tent Size ?

For the first time, you’re learning how to put up a grow tent. Making the conversion from high-intensity discharge to LED grow lights? In either case, it’s critical to select the appropriate LED grow light for your tent size. LED lights provide a significant benefit for both you and your plants when you choose to utilize them. In fact, LEDs are the only lights that are capable of supplying plants with the precise light spectrum they require during the whole growth cycle. These lights, in addition to providing the finest quality of illumination, consume the least amount of energy to operate properly.

The full benefits of LED grow lights, on the other hand, are not available if the fixture you pick is not appropriate for your grow tent.

Step 1: Establish Whether Your Grow Tent is for Veg, Flowering, or Full Cycle Growing

Do you have a vision for how you want your grow operation to be set up? Do you intend to move plants between a specialized veg tent and a blooming tent during the growing season? Alternatively, do you want to keep your crop in the same enclosure during its whole harvest cycle? This is an essential question for a few of reasons. First and foremost, the response informs you of the sort of LED light you require. If your plants will be growing in this tent for the rest of their life, you may wish to invest in a variable spectrumLED that lets you to modify the light spectrum between each phase of growth and development.

Second, plants in the vegetative phase require approximately half the amount of light intensity that they require during the blooming phase. This information is useful for the third and fourth phases.

Step 2: Decide How Many Plants You Plan to Grow In Grow Tent

It is not only about the size of the tent that you should consider when selecting the appropriate lighting for your grow tent. It’s also about the size of the canopy and how well it occupies the available area. Plan on providing at least one square foot of space for each plant if you aren’t sure how many you will be cultivating. Allow adequate room for your crops to spread out and become wide and bushy. When the plant begins to blossom, you will be in a great position to harvest large quantities of fruit.

Every LED grow light should include easy-to-find specifications on its product page, just like any other electronic device.

Step 3: Estimate How Much Wattage You Need for Your Square Footage

We’ve included this step since it’s one of many considerations to examine, but it’s not a hard-and-fast rule, and it should be treated as such. We’ll start by sharing a common rule of thumb, and then we’ll explain why you should use caution while using it. According to conventional wisdom, you should aim for 32-50 watts per square foot of growing space. If your grow place is a specialized veg tent, you’ll need something closer to 25 watts. Using this example, if you’re dealing with an area of three by three feet, you’d potentially require an LED light with a power demand of somewhere in the range of 225 watts (vegetative) and 450 watts (hi-intensity) (flowering).

  • The difficulty is that watts don’t tell you anything about the quality or intensity of light produced by a fixture, only its quantity.
  • Top-tier LED lights are incredibly energy-efficient and can generate an equal spread of high-intensity light while using only a little amount of electricity.
  • This lamp, on the other hand, has a PPFD rating of 800 and covers a coverage area of 3′ x 3′.
  • We’ll go over it in more detail in Step 4.

Step 4: Compare PPFD Levels of LED Grow Lights

You may obtain more in-depth information about PPFD measurements by visiting this page. In the meanwhile, we’ll try to make things as simple as possible. The photosynthetically active radiation (PAR) transmission factor (PPFD) informs you how much photosynthetically active radiation (PAR) really reaches the canopy from a certain hanging distance. Here, we’re talking about the amount of useable light that makes its way from the bulb to the foliage. Follow these steps to grow plants that are healthy and flavorful:

  • Seedings and clones require 200-400 PPFD
  • Vegetation requires 400-600 PPFD
  • Budding and blooming require 600-900 PPFD
  • And fruiting requires 900-1000 PPFD.

Understandably, it is necessary to select whether you want to commit your grow tent to a certain stage or to the complete cycle before you begin.

When reviewing the characteristics of an LED grow light, be certain that the light can deliver the following benefits:

  • The PPFD level required by your plants
  • It should have a broad enough covering area to guarantee that the entire canopy receives sufficient quality light.

It is also crucial to note that the PPFD of your lights is dependent on the height at which they are suspended. The quality of the light declines as one moves further away from the bulb. It is possible to measure the quantity of PAR that is available at a certain distance from the fixture using a PPFD measurement. When you look at the PPFD specifications, make a note of the distance at which the measurement was obtained. For example, the 200-watt SolarXtreme 250 has a 500 PPFD at 18″ and weighs only 18 pounds.

When deciding on the best LED grow light for your tent size, remember to take into account more than simply square footage when making your decision.

Don’t be fooled by low-cost lighting options.

To note the fact that having some assistance while erecting a tent for the first time is quite beneficial.
