If you are using just clean Ph adjusted water it will take about 14 days to do a proper flush.

You don't need to over water them to do a proper flush, drowning your plant will not help to flush them any faster. The plant need to uptake the water too so you can clean out the inside of the plant as well and not just the soil.

Using a commercial flushing product is always a bonus and can speed up the flushing process by a week.
Zandor Reviewed by Zandor on . A question for flushing... Okay, they've been getting clear water for well over a week now, they're a couple days over 8 weeks, and I expect them to go at least 1 more week if not a bit longer..I watered them the other day and want to put them in the tub to run lotsa water through them, the soil isn't completely dry..I've had problems with overwatering before but are they going to care this late? I know as long as before harvest it's not damp it shouldn't be too bad, but are the plants gonna get pissed at me for Rating: 5
