When you take 2' off the top of the room for lights and vents and 1.5' off the bottom for pots, suddenly that 9' is down to 5.5' - so that's the max height of any plant. I can actually have 12 plants in veg and 12 in flower cuz I'm growing for my sis too and there's a provision for that in the law. So I'll have 12 plants and just need to decide what will be the most efficient to way to farm them.

I started my plants in a 2'x2'x4' growbox with a whole bunch of the small cfl's. When I added a 125W cfl, they really loved it. The 125W was reasonable enough - $40 - and the plants liked it, but you get any bigger than 125W and they start wanting over $100 for the bulbs and that's just not cost effective compared to HID's.

Need to do research...
PharmaCan Reviewed by PharmaCan on . When am I using too many watts? Using too many watts for a grow is one of the indicators that can get the police on your case. I was just wondering how many Watts a typical household uses in an hour/day. How many Watts of power before you are obviously doing something out of the norm. If anyone knows of an ways to produce Electricity without leaving a sign, post some Ideas. I thought about a Hydrogen Generator, they exist, and can be converted from existing Internal Combustion Engine, but Hydrogen Rating: 5
