I have a black 5 gallon bucket, form fitting lid w/6" net pot, air pump rated for 60 gal aquarium (2 output), two 6" airstones and hydroton. Everything that I need for a basic dwc "bubble bucket".
I am doing a test run...drilled two holes toward the very top of the bucket. I run the airline tubing through the holes and place airstones on each one. I've filled the bucket with water so that when the lid with the net pot is placed on the bucket it comes to about 3/8" from the water.
Here is what I've observed so far....the first three inches (top layers) of hydroton does not seem too moist. In fact, it seems pretty dry (not bone dry but barely moist). I am concerned that when I insert a seedling, the roots will not have enough moisture to grow. Should the top few inches of hydroton be moist/wet?
