Alan, they are in the fridge with others that need to be started. Right now, I got too many trees that I must sell off first.
Eddy my system does run for 24hrs inside my garage which is around 60 degrees inside. The water does get warm but not hot. The big EZcloners are the best IMHO. The more water mass the cooler the water will be. If folks are concerned about the pump heating up, then get yourself one of those AC multi-switch with built in timers. I have 3 of them. One is connected to my pump and one side is connected to my T5 lights. One plug stays on continuous--this is where the pump is connected. The other goes to my lights. The lights come on at 7Am and go off at 6PM. It pretty cool! The timer can be controlled in 15 minute intervals. All I have to do is set it and forget it! But I do add 1/4 cup of hydrogen Peroxide every 3 days.
I know EZ Cloners are expensive but if you have a prize cutting that you really need propagated, EZ Cloner works without a doubt. The best thing I like about it is no gnats!
