Although it has its potential pitfalls, a lot of produce in our supermarkets is grown in rockwool. Lettuce and cucumber almost exclusively. Commercial growers with multimillion contracts don't use it because they are idiots.
If use good quality Rockwool like Grodan, condition it right (GENTLY ph it down) and get the irrigation right so the plants HAVE to go looking, its awesome.
I run aero now with no media at all and I do miss the insurance of the rock wools moisture retention. Now if a pump fails, my stuffs crispy in an hour if I don't get to it.
Even in NFT with just 3" cubes it could go hours between pump runs.
I may go back to hand watered R/W for mothers actually. Nice simple easy way to keep a plant. Cannazym for maintenance and its good.
Sturgeon general - thats a beauty right there
