i say start as soon after the last frost as possib;e, good genetics, and getting that stem as firm and strong as possible go 4 high in n nutes and keep the pests away as well as possible, oh yeah do some amendments to the soil your going to put it in buy adding compost, bat guano live worms and worm castings your roots can go as far as possible at the first site of buds start using high in P and K but going easy at first and do some supercropping and then start using molasses, continue to ward of pests and no matter how much poundage you get always cure it properly
stay cool
Keep tokin
peace
