I have a 1000W light over 9 buckets covering a 4ft x 4ft area. It also has a control bucket and they are all interconnected with 1/2" pvc pipe. I then have a smaller pond pump in the control bucket pumping nutes to the farthest bucket, basically constantly moving the "water" down there. Then I have a little aquarium air bubbler with a 4" stone for air bubbles.

My question is: With the water constantly moving, pretty evenly through all the buckets with the pump, are air bubbles still necessary? They seem to clog up about half way through the flowering period anyway. I'm wondering if anyone ever has gone without the air bubbles and what kind of differences one might see between using air bubbles and just running a pump and circulating all buckets.
