So I checked my water temps and it was 28.8 c degrees. I guess it's back to rock wool until I can find a way to control water temps
Just send it to me if you aren't using it lol.. Sorry you are having problems with it, I say keep trying and once you get aero cloning dialed in you won't mess with anything else.. BTW, what is your light setup with the cloner? I had problems in the past with too strong lighting for my clones, that's really the only time I have problems with it. I use two (2) 24 watt CFLs about 8-10" (I think) above my cuttings. Weak lighting encourages the plants to form roots rather than photosynthesize.
Its amazing - I have been using my aero cloner for well over a year, maybe 2, and I just rooted my clones on this round in only 7 days. My furnace is right next to my tent with the cloner in it (basement), and the heat from the furnace, coupled with me misting once a day improved the humidity to the point of cutting the rooting time in half! No joke - my normal wait time for clones in about 12-16 days. My point is - even folks who use the aero cloner can improve its use after long periods. Don't give up on that cloner!
