Hello. Good Question. All your suggestions are good. I find it's best to have a plan before you start. When you buy seeds, get ones with a similar flowering time. Or say I'm going to flower for 70 days. The plants with a shorter flowering period will do just fine with a longer flowering time. I fined that the longer you flower a plant after the flowering date (with in reason) the more of a head buzz you get. Good Luck. Chuck.
