SOG you need clones to do it, so you can flower the first batch of seeds chose and grow the best mother then clone it. you will need like 4-5 weeks maybe more to have sexually mature plants that can flower and clones need 3-4 weeks to have enough roots, probably more. dont focus on SOG focus on decent harvest in quickest time from start to end. you will need some experience to perfect a SOG system, and if it's for personal use you would not need it if you make good use of that lightdont really wanna veg this long thought about going sog with 10 C99 (reg so there wont be 10 females i bet)
