what size led light for 4×8 grow tent

The most asked question “how much led lights for a 4×8 grow tent is enough“? Actually Determining your light size is basically a two-steps process. First, you need to calculate the size of grow space and second, find out the canopy dimension.

People often ask us, how many Watts need for a 4×8 grow tent. Well, keep your eyes hooked below for the answer!

During the FLOWERING STAGE

To produce a favorable yield in the flowering period, you need a light with an output of at least 50W per square foot of growing space. Now your 4×8 tent is 4ft long and 8ft wide. Which gives you a square foot grow space of (4ft x 8ft) = 32. And then, multiply this figure by 50W: (32 x 50)W = 1600 W.

So, how much led grow light for a 4×8 tent need at flowering stage?

This means your 4×8 indoor tent requires an LED grow light size which is at least 1600W or, you can use combine multiple led lights which will be totaling to 1600W.

During the VEGETATION STAGE

In the vegetation period, you need only half of the power compared to the previous flowering stage. In simple words, if you needed 1600W in the flowering stage, then in the vegetation stage you will require: (1600 ÷ 2)W = 800W.

So, how much lights for at veg?

This implies in future vegetation periods, your grow tent will require an LED grow light size of at least 800W, or you may combine multiple lights which will total to 800W.
