So I'm gonna be starting a grow using a hlg qb135 in a 2x2x4 grow tent now my question could I scrog 2 plants and get 3 to 4 ozs per plant or would I need a 3x3?
You could pull that much or more in that space, but there are a lot of variables more important than space. Is your light strong enough for the space? Are you growing stains that are known to produce? Is your nutes/environment dialed in?
If it's your first grow just do your best and see what happens.
Not my first grow but my first grow since I've moved the nutes I'ma use are gh the light I have is perfect for the space I'ma do some topping and of course a scrog pretty much got everything dialed in down to the temps and I'm going some strains I had left over from my last grow some animal mints from seed junky genetics
