i wouldnt even put peroxide in your water, just put root hormone on the stems to seal it before going in the cloner. also keep your airstones in it. cleaning the ez-clone machine is just by adding a cup of bleach after you fill it up full with water and let it run for about 30 minutes, after it ran put your neoprene collars in there and give em some dunking then rinse all of it out well. i kept my temps kinda stable by keeping my single t5 up high and a fan blowing on the res, plus its seperate from my flower/veg chambers, plus my room temp is 72degrees. also you dont need to worry about humidity dome. my rooms rh is 20-30% the cloner keeps the moisture to the roots so the leaves never get a chance to transpire all its water out. oh and thanks rusty, i knew there is always appreciation for plant porn.
