is it necessary to flush soiless mixes? if so why and how often.

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!

I agree...good ferts make all the difference. Buy shitty products...expect shitty results.

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.

my metas smell pretty shitty but the results were anything but!
