What could I expect to spend on a DIY grow box? Ideally I'd like to build something tall enough to grow up at least 12", with lots of room for LST. Also, I'd like to use the box for vegetables as well, so I'd need to buy a timer that's easily adjustable to whatever I'm using. I've got some broken speakers (about 24" high, and 12" wide, maybe a bit more) that I could empty out and use as a box, especially if I were to connect the two. So, if I have the "box" how much do you think it would cost to get the lights, timer, fans, and all that? $50? $100? Oh, and I'll be using CFLs
It depends where you live dude. Just check out prices online and add up yourself so that you know for sure.
