i am growing in a 2' by 3' closet going to plant 2 seeds using 2 23 watt 100 watt equivalent bright white clfs going to use fox farm soil and have bonicare pure bloom pro pure grow pro and calmag. any tips would be great
HID in a 2x3 space can be difficult with heat but if you can do it great. If not 4x23w cfl will work decent. A small fan and Pick up some Safers End all or neem oil for mites if you want to prepare.
Ambient air makes such a difference. Genetics also make a difference on light usage. I have a newer digital ballast that can output 250w/275w/400w/430w and this would be the best bet for you but $200 + a bulb in canada. It can also accept mh or hps and runs cooler but $$$
I've used a 400w hps in a 2x3 closet, but you need an air cooled hood and ducting. For cfls in a space that size, you need a minimum of 300 actual watts to go through flowering.
