Recirculating “ebb and flow” in buckets - 55 gal drum res to 8 2 gal pots with hydroton. Three fills daily, 15 mins of flood a piece!
If it matters - Jack’s 321 on old recipe (3.6, 2.4, 1.2) using diluted sulfuric acid for PH down. Water is city tap but it runs 0 EC though ~7.5+ PH.
Thanks for any input!
