Type of Plants

Every plant is unique in its structure, stem, characteristics and leaves. In a given tent size, the plants will grow spontaneously if they receive proper ventilation and circulation of air.

It’s recommended not to overcrowd the tent with plants as the environment might lack proper light exposure. Keep in mind the plants will mature and at that stage, this tent has to fulfill all the necessary factors to allow the plants to grow naturally.


Plants have many requirements and light exposure is one of them. While talking about lights, the height gets involved.

The yield of a 5ft height tent and a 4ft height tent is not the same. Though this factor is not as crucial as the vital factors we are explaining here but to let the gardeners know.

Well, let’s not forget about the light exposure. Regardless of the plant’s growth stage, the plants need 30 watts for 1 square foot in a grow tent.

For a 2×2 ft grow tent, the required light is 120 to 140 watts. However, plants can’t absorb only 60% of produced light. Now, if you calculate,

Required light power = (130 x 100)/60 = 216.7 watts

If you round up this number, your tent needs 220 watts. Don’t enlight the garden with an unnecessary number of lights because it will cause burning issues for the leaves. The leaves will lose color and die.

Strategy Of Cultivation

When you plant regularly, the tents for each stage need to be separated. Why should you do this budget-consuming step?

Well, this might be budget-consuming for you at first but this step is about saving your crops. In the end, you will earn way more than invested money.

How is this going to happen? I will explain in detail. Hop in!

As a continuous harvester, the cycles of a plant’s growth hampers the number of plants. The small plants in continuous harvesting will result in more plants in your tent. So, I am asking you to have more than 1 tent in the garden.

However, it depends on the intention that how many plants you are planning to grow. If you are planning to grow a few plants and let them grow wide in your garden, you can avoid this strategy.

Train the Plants

How about receiving the best yield from the plants? If you are ready for it, let me tell you.

When the gardener is planting more plants in the tent, it increases the plant density. Don’t think if you have fewer plants in the garden, your garden will provide the best yield.

Decide the style you want to acquire for gardening. There are ScrOG, Bush, SOG, Mesh, or Low-stress training.

To get maximum yield, maximum yield per plant, ScrOG style will provide you with the best. In the case of receiving a maximum yield per kWH, you can choose SOG because of the vast canopy production.

What is ScrOG?

Answer: This is a method to grow plants a screen above the medium by bringing the upper branches downward and lower branches upward.

What is SOG?

Answer: SOG is a method that is used to force the flowering stage of marijuana growth when the plants are young. If harvesting plants earlier is necessary, you can try this method.

What is Low-stress training?

Answer:  Low-stressing training means modifying the branches of the plant and receive the best yield.

How to Use ScrOG Method

If you allow the ScrOG method, this will increase the rate of crops by 10 to 20 percent. 


  • Place the screen at 12”-15” and top the leave
  • You have to tie plants with that screen when the plants have grown 4”

What are the advantages?

  • No fluffy buds
  • No light went in vein 

2×2 Yield For Different Strains

Choosing the best yielding strain is a crucial part. The strain ensures the quality and possibility of receiving the maximum production.

If you can choose the right strain, you will observe a massive change by yourself in yielding. To understand this fact better, let me give you an example –

Strain A turns into mature plants within 20 days and strain B matures within 15 days. Clearly, strain B is more preferable to strain A.

For the variation of each plant, their cycle is unique from each other. When you select the seeds, choose the highest yield rate strain to have the best experience.

How to Measure Yield?

You might not know how to measure the yield appropriately. Let me tell you about this quick method.

When you are collecting buds, they have to go through a drying process which allows the grower to receive only 25 to 30 percent weight.


If you are a beginner, consider the space where you want to set up the tent. The number of plants you want to grow in the tent is another matter of fact.

When you have space to place the grow tent, purchase a grow tent that is 1 or 2 ft smaller. Leave the space for
