yes you do have to flush and the reason is to keep the roots nice and clean,how often is up to you i,d say every 2-3 weeks, keep it clean bro
I dunno'. I've never seen so many folks ready to flush so often. "IMO", it only serves to deprive the plants of a steady supply of nutrients. Not to say that cleaning of any build-up of saltz isn't good, but I fail to see an advantage to "flushing" the medium of all nutrients so often. In "my" environment, a good flushing will take 7-8 days to dryout enough to feed again. A week without a food source just doesn't sound healthy to me. Sorta' like "binge" eating, or anorexia, or bulimia.. I'll use flushing, "if" I find a problem that I think warrents it. Over fert, PH inbalance, ect. I've not had saltz buildup problems since switching from "lowend" ferts. Just my opinion.
^^Yup^^ what hicountry said! once you get you fert schedule right the only time to flush is the last 2 weeks and then thats not a real flush its just watering with plain water no ferts the last couple of weeks. listen to the man HE KNOWS IT!
to be honest guys. thats what i thought. i never understood what the fert. deprivation did? i guess the idea is that it washes the salts away, but do you get that build up with fox farms and earth juice?
i don't get any salt build-up from using Fox Farms in my hydro grows. and i agree with nob and hiC ... i use water only in my buckets the last 2 weeks or so. i change the water in my buckets every 2 weeks, which some may interpret as 'flushing'. i just call it good growing hygiene.
