some seedlings sizing up

some seedlings sizing up, siberian peaches and manchurian apricots have been taking off in large plug trays. i'll post a nursery tour later in the month, some of the wild flowers are still small and look like an empty tray. how much to grow, who knows I'm just trying a bit of everything with the seedlings. my flow is to start seeds in april, and trasplant into trays or even pots through may and june, while I pot up or plant left over stock. and about right now I've just about finished both in time for softwood to start, then the greenhouse is all about timed mist and hardening off.
