What size LED light for 3x3 grow tent?

What you really need to keep in mind is that most weed plants, especially larger ones, need at least 2 x 2 feet of space, if not more, so a 3 x 3 grow tent is going to fit 1 plant comfortably.

The most important factors to consider when choosing a cannabis grow light for a 3x3 foot grow space are the light intensity and uniform coverage area of the lights.If you pick the wrong grow light your plants won’t grow to their full potential. All the options I mention below meet or exceed those requirements.
