Very nice setup.

Knock your PH down to 5.0 or 5.2 and it won't go up so fast.

When we first put clones in our drip with hydroton it does the same. We check it twice a day and bring it down. Seems when we only bring it down to 5.6 it rises back fast.

Don't worry about the acid it does not hurt anything. Not having it hurts.

We have used what comercial boys use sulfuric acid.That's right battery acid is what large hydro opps use for ph down.
LOC NAR on probation Reviewed by LOC NAR on probation on . pH keeps going up, up, up, and away.. should I be worried? Hey everyone, i've searched around the site and found many people say that ph goes up normally a lil faster during veg but i'm wondering if what i'm seeing is excessive. I've grown in soil and rockwool before but i just started a new grow using hydroton and a drip system in 1 gal buckets.. here's the setup: - (4) 4x4 trays fed off of (2) 20 gal reservoirs using a drain and recycle system. - (16) 1 gal pots per tray (1/sqft.) with clones in a rockwool plug in hydroton (1 tray has only 7 Rating: 5
