And I stand by everything exept the aeroponic thing.Zander was right about that...believe it or not.

Seedlings do better under flourecents until there big enough to handle that kind of light...

did you shake out your rockwool before you put seedlings in?
IMHO; start your light at 30" and move 6-8" closer every 2-3 days until you see plants perk up then keep them at that relative distance. they don,t need a lot of light at first so Fluoros are the best choice...right on top of them if you got fluoros, if not see above.
Zandor; I had a thought...you grow using drip; right? From the way you explained the nutrient buildup in the rockwool I realized that using drip would cause this buildup...that said...using bubblers, I have found that if you pre-soak in the same ph adjusted nute solution overnight.put the rockwool in hydroton and leave it alone; it get's fairly dry and everything stay's sweet in the res...but if you flush the rockwool thru the top it rinses the rockwool, your res ph goes apeshit!!! the rockwool becomes wet again and you experience nute buildup problems and moisture problems.
Thus, IMHO: Shake rockwool out (like shaking a paintbrush) to get rid of extra moisture, and do not flush rockwool after putting in grow medium...add all nutes/ph water by pumping it in or lifting whole top and pouring it staight in.
Does that sound right, yes. of course IMHO...latewood

I do know of lots of people who use Rockwool, Iâ??m just not one of them anymore. Your idea should work just fine, keep the light away from the Rockwool and alga should not be a problem. Rockwool is probably the #2 grow medium in the world. Just look around and you will see who uses it and how many problems they have too. There are more problem grows then there are success stories in the past 4 years with Rockwool on all the forums.

The only correct way to use Rockwool is to presoak it like you said.

Grow rocks can experience toxic salt build up yes. If you flush between vegetation and flower cycle you donâ??t have that problem. Grow rocks only hold water in very small, small amounts. That by itâ??s self helps to keep the nutrient build up down. Flushing for preventive measures is always a good practice and eliminates that problem.

Rockwool by design retains water and that can be a receipt for problems of over watering and a number of other nutrient imbalances.

If you get the system dialed in right Rockwool can grow fast too. Itâ??s just not my cup of tea thatâ??s all.

Hell Iâ??ll use Rockwool over Miracle Grow any day.

Zandor your a Dick!
You take this way to seriously.
This board is way more opinion then fact so lay off me for stating mine.
Another opinion...Go fuck yourself!!!
