Wonderful enzyme concentration for gardening , but for “clogging” sensitive growing like a lot of hydro growing, may not be a good option. For me ( coco) works awesome and ultra cheap!

Keeping this one upstairs bro

Yeah man if everything seems to be going good u really should t have to mess with it just look in ur buckets and see if there's a bunch of grime/buildup, and if.its not bad I think you could get away with just topping off as long as your plants tell you it's ok... And if you want to get alot of the somution out of your bucket/Rez just DNT top it off for a coukem days and keep an eye on it, and like I was saying as long as there's not a layer of grime on the I side the next time u top it off it will be damn close to a Rez swap if u just let em drink most of what's in there. Some people may disagree with what I'm saying I'm just sharing what has workd for me I use a recirculating system, but I'm in the middle of a dirt run rn cuz a bet I have going with a couple friends. But I still had to have a couple hydro plants going cu it just ddnt feel right so I made a couple 5gal buckets with airstones and top fed till the roots were established now they are just riding out, I'm in week 8-of flower ish... And I think I've swapped out the entire. BUcket maybe 2 times? As long as ur plants are happy, u should be happy too!?
