Well Im glad I can step in and offer some input since that is exactly my Ebb setup I am currently running. I am using 15 3 gallon pot system with a 32 gal res. These are my first successful batch of Kushberry clones I took off the previous run. My setup is going from 1 gallon pots filled with coco during veg under Badboy T5 flourescents, then transplanting the 1 gallon coco into the 3 gallon buckets filled with hydroton. Pics are shitty .off my camera fone but Im into week three with just rediculous results. Using Cutting Edge Solutions 3 part with additives. So far I have had no issues with clogging or coco breaking completley apart in the hydroton. When I raise up the plant bucket from the flood bucket there is minimal coco particles floating, not even enough to make it back through the bucket hole. Ill keep some more pics posted later. This is my first hydro setup and I am loving it! Will never go back to the drain to waste setup!
