Thanks Bonbon for your advice. Nonetheless, I'm still determined to go aeroponics instead of rockwool. Now you must be thinking, "this guy cannot get it right with Rockwool, how can he expect to succed with areo?" The reason is not that I cannot suceed with rockwool, but that I cannot succeed with a handwatering system. I am certain rockwool would not be a problem if I used it properly in an flood or drip system. As you said, the instability cause by handwatering leaves too much to chance. Since I have to invest in a new system anyhow, I might as well go with the best that is out there. So I go aero.

After sprouting, I used a weak nutes solution for the seedlings as recommended by the manufacturer (4-6-7 @ 1 tsp./gal. of water), kept seedlings at around 1- 2 inches from floros lamps, 24 hours /day except on sunny days when they were moved to the window sill. I fed and watered the plants by hand, flushing the rockwool with nutes solution at least once per week and watering as needed with just plain water between feedings. At two weeks old and Rating: 5
