Root exlercator??

For sure, if you are gonna do that maybe flush your lines more often with fresh water to prevent build up.

RE is a waste of time and cash now that they were made remove a certain hormone that made the roots huge, furry and they were as white as snow.

You won't see any difference if you don't use it. I threw my money away for years on that product. Once you pay the big money for the bottles, one has no choice but to see it work. A lot of nutes are like that.

Yeah i already bought it so i have to choice now it was either canna rhizotonic or H&G root gold
