Up to 90, no lower than 77 - My clone box is 100 at the base, and the air is a little under 80, 100% success not counting the two I've inadvertently killed (dome was too small on one, so it rotted from the outside in, and the other one got too much air)

I've got a clone in the box after 2 weeks in flower, and its going well, still strong (been a week) So she'll survive. The warmer the bottom is, the more and faster roots will grow and expand, I know your using a hydro system, but for those using soil, this stands true as well, but please remember, the hotter your seedling medium, the faster it will dry out, I water my cuttlings and seedlings 4x per day (just a few drops, just keep it moist). I've seen bases as high as 120 in hydro, mine is the hottest in soil I've ever seen, but it works for me

:thumbsup: Keep it up Joe!
low_rdr Reviewed by low_rdr on . Tips for tuning an ultrasonic atomizer type cloner The build is a typical Rubbermaid bin type setup with a clear dome. I've been adjusting and tweaking since not last Thursday but the one before. my first clones where done in the jiffy tray kit. They turned out good but I thought it took to long to get roots showing. (maybe that was just me) I have tried the standard garden center variate rooting gel and the powder in this new setup. I thought the powder worked better despite what my hydro store guy said. But now I think it was just to damp on Rating: 5
