P.S. I decide when to flower based on size in the veg room. I want my indicas to finish around 48 inches so that means when they reach half that size, 20-24 inches, at 20/4 it is time to flower them. Keeping a perpetual grow going is challenging for even experienced growers. I have discovered that timing the movement of pots from the nursery (dome closet) to the veg room then the flower room is the most challenging. BigSteve.
