Dwc and clearex

hey i've been running dwc system 6 weeks into budding and have been using clearex from botanicare for flushing i use it the way it suggest to run for 15-60 mins or untill ppm stops rising but i was curious to know if u can run the resivour for 24 hours or will this harm the plant any help from someone has used botanicare or knolawdge with them is appreciated thank you

I use FloraKleen for flushing my DWC system. It's basicaly the same thing different name brand.The directions on the back of my bottle say to flush for one to two hours between nutrient changes. For final flush before harvest flush for 48 hours. Concentrate for both types of flushes are the same. 24 hour flush shouldn't be an issue before harvest.

i use the whole botanicare line and also dwc 5gal buckets and i run clearex for two days what i do is when go to flush i have spare buckets so i fill one with plain water and i rise roots with just water kinda just dip up and down to clean off some nute buildup then put put in bucket with clearx and flush for to days works fine for me
