Your thoughts?

i have a 24x24x48 tent I purchased, I want to grow 4 autos, I have two 300w mars led lights ocean forest soil fox farm nutrients and air pots.

What kind of yield could I expect?
More light?
Less light?

I can tell you that a single auto grown under good conditions will fill that tent. The combined Mars fixture should do a good job lighting that space but you're going to be severely height limited with that tent.

Yeah man use it for cloning, a four-by-four will work better for 4 Autos
-good luck
