also, i have heard not to use the 3% peroxide because it has different chemicals in it where as the 35% is food grade and dosnt have those additives. anyone using the cheap 3% solution? just curious, way cheaper to buy the good stuff. quick question, my bubble cloner, recently, has been rotting the stems of my cuts so naturally i scrubbed out the rez, lid, air line , bought new neoprene collars and it still happened. so ive gone from 100% succes to less than 50% now. earlier this week i scrubbed it out again, bleached everything then hit it all with peroxide (35% straight out of the bottle , no diluting it), let that soak for a few hours then rinsed everything super well and now have it back in action with some gsc thinmint cuts aswell as some GG#4 and some ecsd and og. i used 3mls/gal for the solution and am using house and gardens roots excelorator and kln rooting formula. im hoping this works. if not ill start over from scratch. everything looks good so far, do u think i should use sm 90 or zone as well to be safe? also
