ok im working with 2 24" florescent fixtures that can have 2 bulbs. there 40 watts each and the build are grow build. so thats a total of 80 watts. if i want to keep my plants small and harvest them every 3 months how many plants could i do?
Not sure, I've never seen anyone flower out a plant with that small of a light. If I had to guess I'd say one or 2 maybe, but only if they were trained. If you can't get a HID then check online for some larger sized CFLs, I've 200w cfls on ebay before.
