Best 4×4 Grow Tent Yield: A Detailed Guide

When you think to set up a 4×4 grow tent some common questions come to your mind and make you loaded, for instance, how many plants can a 4×4 grow tent yield? Or how much wattage a 4×4 grow tent needed? And so on. Here we will try to provide all the necessary answers to your asking step by step.

A 4×4 grow tent normally yield anything between 1lb to 2lb (16-30oz). Yet, there are some other factors that influence plants’ yield such as, the growing style (SOG, ScrOG, Flux, and Bush), the height limit, the number of plants, the environment, etc.

The 4 x 4 indoor grow tent is the most popular size grow tent. It’s a perfect match for both new growers and experienced growers who are looking to harvest 6+ medium to large plants every 3 months.

A 4×4 grow tent fits 600 to 1200 watt grow lights (or equivalent) and suitable to anywhere of your home which makes it easy to hide away for a secluded growth.

Some Essentials for Grow Tent

  • The canopy for your garden
  • Grow lights (their size and the distance are above your plants)
  • Ventilation equipment (carbon filter, intake/exhaust fans, clip fans)
  • Accessories and tools (reservoirs, pumps, soil, nutrients, shears, etc)

Once you have your required growing space you’re ready to start looking for a grow tent. But, there is a good relationship between the grow space area size and the yield, you must regard those factors before setup a 4×4 grow tent.

Tent size is always one of the many limiting factors that may affect your after-effect. But you can get an estimation of yield out of a 4×4 space by putting some conditions on the rest of the variables.

Necessary Attributes for a 4×4 Grow Tent Yield

There are some aspects of a 4×4 or any size grow tent which determine your plant’s success-

  • The growing style (ScrOG, SOG, Bush, Mesh, or Flux) can fit up to 15 plants
  • The light type (HID, Fluorescent or LED), light watt range from 600 to 1000 (or equivalent)
  • The strain

Different Light Types for 4×4 Grow Tent

In this section, we will discuss the impact of lights only to make your knowledge clearer on different types of lights wattage in 4×4 grow tent yield.

To bring out the maximum yield in 1m2 area 400w-600w is enough. So, a 4×4 grow tent requires 800w-1200w. You can use a single 1000w or a couple of 600w lights.

I know many growers suggest a single 600w light at a close height could be enough. But merely a 600w light is not enough unless you’re growing in a 3×4 or smaller tent. You need at least two of them or one 1000w light.

The increasing number of lights also provides adequate heats that are required for your plants. It may be helpful for you to check out the guide on watt requirements for grow room for further information.

Besides the power of light, the light types also have an impact on grow tent yield. As you know, there are basically three types of lights.

  1. HID light
  2. Fluorescent light
  3. LED light

Yield habitually is different under different types of lights though the power is the same.
Let’s see what the yield of a 4×4 grow tent if light types become different.

 HID (High-Intensity Discharge) Light in 4×4 Grow Tent

HID lights are 3 types- MH (Metal Halide), HPS (High-Pressure Sodium), CMH (Ceramic Metal Halide).

To add reflectors or hoods, you can get the most out of the light energy. But heat is a severe problem that comes with HIDs. Please install heat removal tactics if you have decided to use them on your 4×4 tent.

Now, let’s have a look at yields.

Get Maximum Yield

If you can properly utilize HID light’s heat and energy, you must grow 1 gram of buds for 1 watt. Therefore, it’s possible to get a fresh, high quality yield of 2.2 lbs. just from a 4×4 area.

Yet, there are some conditions to have such a high amount of yields using HID lights.

To most growers, it’s common to use one particular light throughout the entire growth period of plants. We advise you to use MH lights at vegetative stages and then put on HPS lights when the flowering period comes to get maximum outcome.

Fluorescent Light in 4×4 grow tent

Fluorescent lights are commonly 2 types- CFL and T5. Cannabis growers prefer fluorescent lights for low key indoor yield.
If you are a newbie and you are in confusion with fluorescent types in 4×4 tent, our advice to use CFL lights because T5 lights are preferable to use in a bigger atmosphere.

Get Maximum Yield

It’s expected to grow 0.25 grams of buds for 1watt under fluorescent lights. So, with a 1000w fluorescent light, you can yield around 0.5 lbs. in 4×4 tent.

LED Light in 4×4 Grow Tent

Many growers prefer to use LEDs because it’s a cost-efficient alternative of HPS lights. LEDs are cooler than all other kinds of lights, and setting them up is also easier.

Moreover, they have a good penetration rate.

Due to producing more resinous buds, many growers trust in a combined LED + HPS lighting system.

We can’t completely insist that the method is super effective, but growers have a great experience with following it.

Get Maximum Yield

Comparing to HPSs, LEDs get slightly less yield for each watt. The most common yield for LED lights is 0.5 grams for 1watt of power.

It means, if you use an 800w light in 4×4 grow space, the total yield would be from 1.1 to 1.5 lbs.

For the low budget grower, it’s advisable to use LEDs. Don’s come to be as costly as HPS lights because they include heat management costs too.

Different Grow Methods in a 4×4 Grow Tent

In this section, we will discuss how many plants you can grow in a 4×4 space? And, what growing style you are going to follow to get the maximum yield? Here we will mention different styles of yield like ScrOG, SOG, Bush, Mesh, etc.

Actually, your plant’s training and strain determine the number of plants and the style of yield.

Now, it’s a crucial question of how many plants you should grow in a 4×4 grow tent for a better outcome? Well, except for some special cases, here is the best plant density for maximum growth in a 4×4 tent.

Plants To Grow Per Square Meter

  • The range of growing plants for SOG is 4-16 per m2
  • The range of growing plants for Pruning is 1 per m2
  • The range of growing plants with low stress training is 4 per m2
  • The range of growing plants for ScrOG is 1 per m2

Now, we will discuss about the best type of growing style, which gives you the maximum yield. To the majority of the growers, ScrOG is the best kind of method in a 4×4 tent to yield. Following this method, you can expect 1.5 to 2 lbs dry.

It also facilitates you to grow 2 plants in a 4×4 space. However, if you try SOG, you can room 15 to 20 plants and the yield would be around 1 to 1.5 lbs.

Different Strains for 4×4 Yields

When your plants fail to live up the quality, you want to consume. You should choose the right genes. Here some high yielding cannabis strains are mentioned in the following.

Big Bud 

Big buds can produce an enormous amount of buds. It gives you up to 1 lb. Yield per plant in a 4×4 space. That’s why it’s the most notorious kind of strain while it comes to yield.
Sensi seeds are currently the best seeds that belong to big bud genes.

Blue Dream

Blue Dream is another versatile strain that grows pretty well. This gene is a cross gene strain of haze and blueberry. But its origin is still unknown.

The growth rate of Blue Dream is a bit slow. It turns into high yielding Sativa dominant plant within 60 days. Yet, if you desire to get dense round nuggets of cannabis, you should pick this strain.

However, you can grow the blue dream, both indoor and outdoor. But, outdoor grown will give you comparatively better yield. A 4×4 space usually grows 1.5 to 2 lbs.

Northern Light

Northern light is short in size and a single cola growing strain. Hence, you can grow this strain well in SOG or Bush/Mesh style and still expect a good quantity of yield.

In a 4×4 grow area, 1000w grow room yield would be 1.5lbs.

Northern light is great for beginners as well as professionals to grow indoor. It’s likely to grow on both soil and hydro system within 40 to 50 days. 

White Widow

You might have seen thick resin cannabis with a solid bud structure, the most possibility that was a white widow.

White Widow is a pretty familiar strain to boost your indoor grows. Due to the quickest flowering time (10 weeks), you can do more frequent cultivation of White Widow than other strains.

Around 1 to 2 lbs. of dry yield from a 4×4 space you can expect within a lifespan of 55-60 days. Apart from its hefty yield, pleasant aesthetics have made the White Widow most popular.

There are some more strains also available besides the aforementioned four strains which are widely familiar for high growth and yield. For example, Super Silver Haze, Sour Diesel, L.S.D, Skunk #1 and so on.

Measurement The Yields

Before getting farther information about yields in a 4×4 grow tent, it’s more important to know about the right way of measurement of yields.

When buds are collected from the plants, they normally become wet for inside water. They are called wet yield. We know that wet yield weight isn’t measurable. To drying up wet yield, we can get the actual weight of weeds.

To dry wet yield, we need a controlled dark and dry place. Now, keep the wet weed under 64°C temperature. And continue the process for 10 to 15 days. Then, we will finally get dry weed. Depending on the strain, dry weed weights are about 20-25% of its wet weight.

Some Useful Suggestion to Maximize your Yields

Do you want to maximize your harvest by trying hard? If you are eager, here are some crucial tips for you from us.

If you are looking to maximize yield, don’t grow on soil. Because many growers fail to get more yield as they grow on soil instead of growing hydroponically.

There are mostly two reasons:

  1. In soil, it is tough to control the number of nutrients that plants receive
  2. To maintain pH and TDS is pretty high with soil

Try ScrOG for Yield

If you grow in the ScrOG method, the growing rate likely to increase 10-20%.

The process of implement will top your plant leaves and place a screen on 12-15’’ above. When plants grow above 4” tie them up with the screen. Eventually, you will see a beautiful blanket of the plant on the top.

You’ll earn these perks besides a boost in yield while the process will be done.

No wasted light

Distribution of lights should ensure at the same height of plants.

Don’t allow soft or fluffy buds

There are so many pieces of advice also available regarding grains, light, ventilation, temperature, etc. Yet, here we only listed those tips which are related to the surface you are growing on.

The FAQs About 4×4 Grow Tent Yield

Q. How can one 2 pounds in 4×4 grow tent?
