<span class="link_user">@Stoney_Stark</span>, honestly they work as needed. They truly are not anything special. The fabric inserts are hard to clean and time consuming. I miss the old hydrofarm round buckets that I use to have 20yrs ago for ebb n flow. I just buy new fabric inserts each run now. If you got the money there a good investment tho. It cost me 0 per run (24 pots)for new fabric. Saves me hours of cleaning the old one tho.i use clay pebbles and reuse them after a good peroxide and water rinse. Thanks for the comments, reach out any time
