i actually had a question for you about the lighting. I was originally planning on using a 150 hps plus some supplemental cfl's for my grow, quite similar to your setup. however, if all goes well i should have 2-3 flowering plants instead of 1. Since you said you need MORE supplemental light for just one flowering plant, do you think it would be wise to upgrade to a 250 or even 400w for 2-3 plants? I'm trying to minimize electricity cost / ventilation needs so im trying to keep the HID light as small as possible.
