When someone asks a question like how many cannabis plants can I fit under the LED grow light in a 4x4 grow tent? Everyone expects a simple and straightforward answer.

Some say 4 to 6 plants, and some say less than 6. Well, grow tent space doesn’t work like that. The question is, whom to believe?

You don’t need to believe anyone when setting up a 4x4 grow tent space or any other tent. After reading this article, you’ll be able to understand that size doesn’t matter.

All matter is training and techniques that affect the tent space.

Sadly, it’s hard to say how many cannabis plants can fit in a 4x4 grow tent size.

Let’s assume the cannabis plant needs one to six square feet. We don’t think that will give confidence to home-growers to prepare their space for cultivating.

Before 4x4 grow tent setup, every home-grower should be able to know how much they’ll be able to fit in this size. At least they should know where they are about to invest their money.

That’s why we’d recommend home-growers to stop thinking about the size of the grow tent and focus on the training and techniques for better understanding.

And don’t worry about the training either, we are here to guide you about everything you should know.

In this article, we’ll be covering different training techniques that can affect the grow tent space. Plus, we’ll also see how many cannabis pots sufficiently fit in your 4x4 grow tent.

How Training Techniques Affect Grow Tent Space?

Different techniques can be performed to maximize the result for a 4x4 grow tent ventilation setup. These techniques will indeed affect your grow tent space.

It doesn’t only affect the space of 4x4 grow tents but all types of grow tents.

There are several different techniques that can affect your 4x4 grow tent space, but here we’re covering only the important ones.

These are the following techniques that we’re going to learn:

1. Sea of Green (SOG)

2. Low-stress Training (LST)

3. Screen of Green (ScrOG)

4. Topping.

Sea of Green (SOG):

Remember, we’re discussing these techniques only for cannabis. You can apply these techniques to other plants if they are a similar growth structure as cannabis.

But first, focus on a 4x4 grow tent for cannabis. How can you make space for more space for cannabis inside a 4x4 grow tent kit?

You can go with the SOG approach; Sea of Green is a technique of growing miniature plants of Cannabis rather than growing the bigger ones.

The main advantage of this technique is when you harvest small cannabis plants close to each other and don’t have much space to spread wider. As a result, your cannabis will take less time to reap.

The Sea of Green approach/technique refers to the “Sea” of numerous cannabis plants, placing them in the harvesting phase while they are still small.

With the SOG technique, you’ll get the exact yield as you would get from the larger plants. So, what do you think about how much you can grow cannabis in a 4x4 grow tent with this technique? Try it and for yourself and share your feedback with us.

Since there are many benefits of using SOG technique but still has some negative aspects:

A quick review of some Pros and Cons.

Pros

● A quick way to harvest

● Substantial yield

● You can grow different strains at once

● Easy to get yourself trained

Cons

● Plants need more caring than the usual ones and consume a lot of time.

● Not a good technique for limited plants

● If humidity and air circulation are not good, there’s a chance of mold and mildew.

● Some plants may grow in an irregular manner, leading to a big problem if you’re working with lots of plants.

Low-stress Training (LST)

Here’s another good technique to make more space inside your 4x4 grow tent. Before explaining how to perform the LST technique for a 4x4 grow tent, you must know what exactly Low-stress training is?

When cannabis plants get older, their leaves become thick and look like a Christmas tree (pyramid type). The cannabis plant becomes outspread from the top and slender from the bottom.

As a result, it increases light penetration to the base of the plant. That’s where Low-stress training comes in to save the day!

Low-Stress Training is a technique that most growers used to manipulate the size and shape of the cannabis plant. It’s a centuries-old technique use to cultivate and prune the plant to grow up into a 2D shape.

Nowadays, this technique is mainly used by indoor weed/cannabis growers to maximize their yield. However, outdoor growers can also use this technique to harvest weed in their gardens. 4x4 tent growers may take benefits from this technique.

Low-Stress Training works like bonsai. Perhaps the shape of cannabis looks like bonsai after performing LST on the plant.

You can do this in your 4x4 grow tent by softly bending the stem and tie them in place.

As a result, the plant will quickly change its shape, and there will be more space available to grow more cannabis plants in your 4 by 4 grow tent.

Remember, we’re only covering the topic of 4x4 grow tents space; you can also use all these techniques in other grow tents.

Screen of Green (ScrOG)

The purpose of Screen of Green is to take the cannabis plant taller rather than wider. It’s a highly recommended technique for a 4x4 grow tent to make it more usable.

The aim of this technique is to bring the upper branches low and lower stem to up. All is done by the help of a screen place on the top of the plants so they can grow horizontally during the vegetative phase.

Topping

This is the easiest technique among all. Topping is one of the best techniques to utilize your cultivation space. If you’re using this technique in a 4x4 grow tent, you’re in real business.

But the question is how topping works?

It’s simple!

All you have to do is remove the main shoot of a growing tip, which will secure two more shoots at the same place. One pinch will make two tops, and two pinches will make four, and so on.

Isn’t it that easy?

This technique works wonders for small capacities like 4x4 grow tent ventilation.

Strain Selection Also Matters

Cannabis cultivation is more of an art than science, says Graham Farrar. Choosing the right strain for growing has always been challenging for cannabis growers. Especially for those who are cultivating in 4x4 grow tent complete kits or any size of grow tents.

You should choose the suitable strain for the right season. Perhaps, you should choose carefully. There are three and most cultivated categories available;

1. Indica

2. Sativa

3. Hybrid

Most of the growers don’t even know which strain they are cultivating. So before starting cultivating, make sure you choose the right strain for the right season. It impacts your final product.

How Many Pots Adequately Fit in Your 4x4 Grow Tent?

Well, it depends on the growing technique that you’re using. If you are using the technique of ScrOG for a 4x4 grow tent, you won’t be able to place many pots inside your tent.

If you’re using Sea of Green for a 4x4 grow tent, there’s a greater chance of adding 10 to 13 (medium size) pots inside the tent.

Sea of Green and Topping techniques are the only suitable for 4 by 4 grow tent space.

Take Grow Tent Height into Consideration

Considering the height of the tent should be the first step before cultivating. Sometimes, home gardeners face the issue of tent height. It depends on the type of cultivating you’re going to do in your grow tent.

You have to look for other issues like grow light. The ideal height of a tent should be 5 feet tall, considering the 400W grow light. If you have enough budget to bear, you can go for the 7 feet and install heavy-duty lights and bigger exhaust and circulation fans.

How Many Plants Can You Fit in a 4x4 Grow Tent?

As we mentioned above, it doesn’t matter how many plants you can fit in a 4x4 grow tent. All that matters is which training technique you use in your 4x4 grow tent.

Usually, the best 4x4 grow tents offer you to grow four to six plants randomly.

But if you’re following the training like ScrOG and Topping, you’ll probably add more plants in your 4x4 grow tent space.

Which size would be ideal for a regular grow tent?

Before purchasing the grow tent for your plants, always remember the following list, then decide which kind of tent you want for your plants:

Size of the Plant:

The number of plants you want to grow will determine the size of the grow tent. If you’re thinking about small cultivation for 6 to 10 plants, you should go for a 4x4 grow tent.

Make sure to add some space for yourself for better maneuvering.

Location:

You have to make sure how much space at the house/room you need to work with. This will give you an idea of how you should buy a grow tent for your room.
