I'm very new to this and was considering purchasing my first seeds from an online vendor. My only question is... what does auto-flowering mean? And, whilst I know it's not ideal, can a plant be successfully grown inside (during winter) using a heat-mat for warmth and basic fluorescent lighting... say... four tubes worth?
If you are going to veg with CFL's, I would highly recommend having around 250 equivalent watts for no more than 3 girls. And a 150W HPS would be perfect for flowering. Make sure your CFL's are at 6500k spectrum for veg, If you use CFL's during flower, use 2700k spectrum. In the future however, an upgrade of a 150w HPS would be highly beneficial. I run 22,000 lumens in a 2 1/2 X 2 1/2 X 4 and have just enough to keep proper vegetative growth. My next grow however, I will be switching to a 150W HPS for flowering. I ran CFL's through flowering on the test run, which is yielding low but still quality bud. A great flowering CFL you can get is a 60w 300w-eq puts out 3900 lumens and 3 or 4 of those will do the job along with some smaller 23w or 32w cfl's. But remember, lumens is nothing, spectrum is everything. Cheers mate,
