Not to out right contradict what carls saying, but DO NOT turn your lights on for an hour in the dark period, that stresses and confuses the plant and you usually end up with a hermie. That may not apply in this situation since lowryder is autoflowering and i know nothing about autoflowering plants, but id rather be safe then sorry.

As for berating you, man that looks great for a first grow! Much better then my first grow looked at that age.

Only thing i could suggest (as i know jack crap about hydro growing) is going with a little LSTing so you can get that plant to bend towards the back of that stealth pc box and thereby using your space to its maxium.

Oh yea, if possible mind giving us a shot of the computer case all closed up and stuff? Im toying around with the idea of buildling a stealth computer box to put some clones in or start seedlings in before i move'em over my rubber maid box.
