got company atm but i'll write something up at some point.
clones and plants are two different aproaches with DWC.
with clones, when there are no roots, you keep the water level at a certain point, beneath the net pot, and when your air pump is turned on, the bubbles will pop and splash out of the sufface, and as such cause a mist inside the tote and gently wet the rockwool. if the rockwool is too dry you can either raise the water level, or increase the bubbles, and as such if it's too wet (if you pinch the corners gently they shoudn't flood water out) you lower water or bubbles.
once they have rooted and the roots his the water, then the bubbles splashing do not become so important, as the water is aerated, so you then just let them go and it's all good.
so when they're really growing, lots of roots, so long as there is an airstone in the bucket you're going to be pretty ok.
there is also talk from a friend at the store who sais that you should keep lowering the water once they've rooted, as this encourages the roots to grow more and more in search of the body of water. i have not yet tried this but i guess it seems logical. for when i'm mroe adept though.
once you get your first clones rooted, it suddenly becomes very straight forward. very daunting to start with though i'll admit
