80F is pretty warm- ability of H20 to hold o2 in solution is inverse to temperature.

Move the cloner to a cooler spot.

If this doesn't help, f#$% the root accelerator and start changing the water daily.
rhizome Reviewed by rhizome on . Cloning machine problems I have a power cloner and have used it successfully in the past BUT I'm having problems recently. The water temp is 80 degrees and I'm not getting any roots so I thought that it might be too hot. Is this too hot? I checked my pump and it's not overly hot so that's not the problem. Any suggestions? I've tried adding ice cubes a couple of times a day and that lowers it but not for long. Rating: 5
