I started off using CFL's and after about three weeks I moved up to a 400 watt MH. When I switch over to Flower I will be using a 400 watt HPS! I also think next time I will use two plants in my Scrog. One Aurora Indica and one Papaya! I also ordered some Super Skunk last week end! I probably will grow her out side though, I'm running out of room!! LOLim waiting on my AI seeds to arrive in the mail, im doing HPS grow tho.probly gonna scrog also.
