I will post a picture, but my grow box is a stealth hydro system, an I've got 4 out of 6 spots used up.

An they are beginning to have leaves hitting other plants, it's just really crowded.
I forgot they double in size in flowering, thanks for reminding me.
I was thinking of ways to grow them, without overcrowding, or maybe ill just let them grow if it doesn't harm them.

I was looking at defoliating an if that may help but I have no idea where to start I know nothing about defoliating as this is my first grow...
