You can get some garden netting and place it on top of the grow rocks and don't fill the water level that high. Lower you overfill drain a bit and you will not have the problem.
Zandor Reviewed by Zandor on . My BALLS Foat!!!!! HELP ME GOD!! :D :confused: This is a troubling time in my household!! I've just tested my Ebb/Flow table with CLAY HYDRO BALLS...and most unexpectedly ...they float. Have I purchased the wrong BALLS??? This means that when the table is flooded ,the balls will rise and sink thereafter ... Does this not disrupt the roots...? Will the plant not become unfooted and topple? Do your BALLS float? Rating: 5
