I have a WW plant that I'm about to harvest, the problem is that I had 10 seeds so I didn't clone the first female which is the one thats almost done, and now I've grown out all the other seeds and they were all male and I don't want to lose the strain. I've been reading all I can about...
if you have a 1 gallon pot you run 3 to 5 gallons of water through it and so on to flush out nutes and whatever else, unless you have some serious issues you shouldn't have to do it very often.
