have a read..

Ur not going to get anywhere near what u get from a photo plant, but theres not the hastle. All u can do is watch them & let them tell u what they want & need & I think u will b surprised...

Keep them short and the branches spread out to maximize light absorption, because 150watts in that size box is not a lot to work with (maybe add a few CFL lights until you get that 400watt light in). I'd check out home depot and see if they have the Canna line of nutrients...some srotres carry em, some don't. But the internet is probably gonna be your best bet to finding quality nutrients, because unless you live in california with hydro grow shops on every street corner, chances are slim that you are gonna find good nutrients around town.
