i have 5 inch net pots, in them i have a 2 inch rockwool cube surrounded by hydro rocks (the cube is hidden)

i have a 12 inch bubble stone and sprayers inside the tank.

the sprayers are constantly misting the roots/rocks. the roots are starting to come out the bottom of the netpot.

is this ok? or do i have to spray at certain times/interval?

You are OK, actually bettter than OK.

In a DRIP DWC, you can actually DROWN a plant, by over watering it. That is why the dRIP has to be on a TIMER. But with your system, you are allowing or adding ample oxygen to the water, and you should expect a most rapid growth. You can run the MISTERS 24/7. I use a similar system, with an underwater pump, that has an irigation hub (small container) that holdS and mixes air with the nutirent enriched water. Trade-marked as BUBBLEPONICS.

thanks. i was just a little worried about the rockwool getting too wet, although it's surrounded by about 1 inch of rocks.

i think the stone also helps keep alge low because the water is constantly being circulated, the roots go white water rafting ;)

Don't worry about the RockWool getting wet. The RockWool was used just to get the seedlings/cuttings to root. The roots are growing around and through the GroRocks. The GroRocks allow the roots to get oxygen ... so the roots won't rot.

Heat is the #1 reason people run the pump on a timer.

Theoretically aeroponics will provide enough o2 to the roots, that they should not need a "drying out" time, like as is required with soil or ebb and flow hydroponics.

However, it seems that the problem isn't the lack of o2, but the fact that when roots are soaked consistently, they tend to mat together. When the roots are fluffy and spread out, they grow many tiny little white hairs that are very effective at absorbing water, nutes and o2. When they become matted, you will see less of these fine root hairs and the plants will not grow as fast.

So, the #2 reason would be to allow the roots time to dry out, not to provide o2 in and of itself, but to allow the roots to "fluff up" again(which they will not do if being sprayed constantly).

I used a hydrofarm drip system for a while and i never turned it off. I dont claim to be any kind of expert but i never lost a plant to drowning.
