i have 18 GDP plants going right now. It's been about a month and they started from clones. They are currently under a 600 watt light for about another 3 weeks or so then putting in a 1000 watt for flowering. check them out =P
no on the c02, and they are about ready to be transfered into 5 gallon buckets in 1 or 2 days, i will have updated pics when that happens. Oh and btw, these pics are about a week ago so new ones coming soon!
