I have a heater, an air stone and the pump on all the time in mine, I use a cap full of formulex and a cap full of root stim and never ph. I always get great results.
ive used formulex before with great results too formulex or ionic hydro grow works for me.
ive always ph ed though but not to add too much ph down so i generally take it to 5.8-6.0
good to know you dont have to ph though,do you ever get yelowing or any deficiencies doing it with no ph adjustments?
