Kdspecial - Yes I water manually. :thumbsup:

The hydroton acts as a protective layer on the bottom to stop roots from completly reaching the bottom and laying in a usually oversaturated area, and the top stops direct light on the rockwool, stopping evaporation and mold growth.

The rockwool holds a insane amount of water, and uses capilary action, so it will suck up water or air. This keeps the rockwool a perfect mix of air and water, while having the small rockwool cubes, there is a lot of space where air is stored between each cube. As of right now, it takes the plants a long time to use up all the water, so I am only watering once avery week or so. I expect to water every day when the plants mature. When they show sex I plan to transplant in to a very large bucket, add an air stone on the bottom, and grow 1 or 2(if i get 2 girls) huge scrogers.

Turtle420 - Yes the pots have holes in the bottom, when I water manually, i completly saturate the rockwool and allow the excess to drain away. :dance:

This style is very similar to a soil grow, just you must be more careful about having the rockwool dry out, and feeding is much stricter since rockwool is inert and everything the plant needs, you must add.
