I read somewhere that so many people try to send illegal shit stashed in coffee that the dogs now sniff out coffee and they'll search through it. Probably a bad idea to transport it, just buy some there.
I think T8 tubes fill fit in T12 fixtures, won't they? You could replace the T12's with T8's and gain a little efficiency. How many plants have you got going?
Like Frank Sinatra said, the best revenge is success. Instead of fucking yourself up, start working out or do something else to improve yourself. That'll really piss her off. :-)
Looks like you've got some room in that cup, you could maybe throw some more soil in there. I'd wait a while before transplanting. What kind of light are you using? If it's a cfl get it about 2 inches from the top of the plant
