Wow donnie youre doing it all wrong for an indoor grow. And when i say that i mean that you shouldnt just let them grow out straight up like that.

What you need to do on your next grow(too late now) is use a trimming technique such as fimming or just straight topping those plants. And if i were you i would also look to buy some seeds that are of the Idica variety.

That way you would have shorter bushier plants and no real need to change your setup. Although side lighting can be beneficial to almost any grow setup.
