The reason is that the area will awesomely receive light using 600w HID lamp often believed to produce almost similar lumen per watt with a high voltage lamp like 1000w. The lamp generates much lower heat output, which allows you to bring it near the plants; hence, it's one of the best lights.

The number of plants to use in a 4×4 grows tent will vary depending on the type of the plant, the number of plants available, the plant's recommended spacing, and the method of growing. If you are planning to grow indoor plants, you can consider one plant per sq. ft. But if you are planning to grow bigger plants, you can have or plan for less spacing.

One chief aspect that influences the number of the plant to fit in a 4×4 grow tent is the method of growing. Let's have a quick overview of the popular methods you can use to grow plants inside a 4×4 grow tent.

Methods of Growing in a 4×4 Grow Tent

Sea of Green

When you employ this method, you will have a spacing of 1 square feet plant. In this method, people appear to force plants into a flowering stage instead of waiting for them to flower naturally (in case they are flowering plants).

The flowing phase implies that you change the lighting conditions to 12/12, 12 hours of darkness, and 12 hours of light. Unlike other methods, this method focus on forcing your plants to get into the flowing phase just a few weeks after the vegetative phase.

The massive benefit of this method is that it introduces flowers early enough, which implies that you will harvest early. When the bud's canopy begins to develop, you must start trimming your plant to help it form buds. If you consider one plant on every sq. ft., you can have up to 16 plants in a 4×4 grow tent.

Screen of Green

This method requires you to plant 4 to 6 sq. ft. per plant. This is mostly referred to as the SCROG method, a broad space requirement compared to the sea-green method. The screen of green method deals with horizontal training, which means you'll have a horizontal screen just above your plants to help spread the tops.

The reason for spreading the plant this way is that it helps enhance the bud's growth on branches. They will try getting to the screen at around 8-12 inches in height during the growing phase. But immediately they get into the screen; you should push them manually to allow them to grow across your screen. This should be done systematically until you fill all the space.

Once you fill up to 50% of the space, you should force and change the plant into the flowering stage. You can do this by having 12 hours of darkness and 12 hours of light. Because this method requires up to 4 sq. ft. per plant, then a space of 4×4 grow tent can accommodate only four plants.

This method requires a spacing of 2 to 4 sq. ft. per plant. Indeed, it is one of the easiest growing methods that foster the better growth of flowing plants. In this approach, every plant demands around 2 to 4 sq. ft. and the aim, in this case, is cutting your desired plant at the right time. If you leave the plant to grow smoothly, you will find the plant's top growing somehow big. When this happens, you may split the top to develop more than one top, which implies several branches.

If you plant one plant, you will have two tops. If they are two, they will have four tops, and so on. The notion, in this case, is to grow plants in the shape of your preference. For example, it will develop crucial elements (flowers) at the top and enjoy maximum possible light if it's a Christmas tree. The good thing about this method is that it does not demand too much knowledge and time; it is just a simple pruning.

When topping, consider a single plant in a 2×4 sq. ft. This means you will have a minimum of 4 plants and a maximum of 8 plants in a 4×4 grow tent.

Low-stress Training

In this method, you require only two sq. ft. per plant. When topping, you often utilize much pressure on the plant, which is not ideal for growth. Therefore, the low-stress training method employs the notion that if the light is farther away from the plant, its intensity is lesser and vice versa.

When growing your flowing plants under a 4×4 grow tent using this method, you must utilize the wires and springs to help buds receive ideal lighting and make the plant spiral. Where enough light is available, you realize better growth, which leads to better or quality flowers.

Here, you require a spacing of 2 sq. ft. to grow only one plant. Therefore, the answer to how many plants in a 4×4 grow tent using this approach can be eight plants.


How many plants in a 4×4 grow tent should never be an issue. You only need to identify the proper method and plant depending on the recommendations in this article. Depending on your chosen method, a 4×4 grow tent should have something between 4-16 plants.
