I'm doing six but in the beginning i had three.. after 30 days i addedd three more that way i harvest 3 plants every 30 days or so "depends on strain"...I'm doing blue cheese i harvest between 2-2.5oz every 30 days (getting better each time i think i could do 3-4 with some more experience) ..with one 250 watt MH in my veg closet(3x3x6H) and 250 watt hps with 6 42 watt cfl's on the side for side lighting in another closet,a 3x3x6H space for a total of 44,200 lumens...ussually I lst 2 of the plants and i let the other just grow on its own..I use bc nutes Grow,Bloom,Boost..Also i have access to Pot of Gold,Skunk # 1,and Northen Lights..But right now i like the Cheese..I veg them only for 2- 3 weeks and then right to the flower room... Sorry no pics i don't even own a digital camera lol what a loser i am..but i'll see if i can snag one from someone..I've been reading the pages of this thread for about 3 weeks now on and off and i would like to say hi to everyone and happy growing..peace!!
