chasv77answered grow question 5 years ago I agree with RealMed..............
I run 1 gal of nutes/water through my 3 gal fabric pots, every time. Regardless of Veg or Flower state.
The small runoff helps reduce nute, salts, other mineral deposits from accumulating in the bottom of the pot.
FYI, I run a 3/1 mixture of qual soil and seedling soil, which really helps with soil compaction during grow, and makes the drain easy.
Using these inside a 2x2x5 grow cabinet, at 78 degress and nice circulation, I wind up having to water every 3-4 days.
I find it hard to over-water if you use the 2 knuckle approach in the soil. Cool to touch, but not damp.
