Def a great investment... Check my whole thread... Lots of useful information...just bought my first one,always made my own.herd nothing but good things.
also u can double up on the clones per collar too!
As long as your grow area is running at optimal temps... I don't see this being a problem... Tell your buddy to put some frozen water bottles in his reservoir... It works great and costs next to nothing... I had to do it a couple times... When I forgot to switch on my exhaust fans...once the summer comes (northern Cal) the thing does not work for shit do to the heat created by the pump and the surrounding air temp. We tried to adapt a homemade chiller to one of them but dude did not want to pony up the money for it so he suffered through it the entire summer.

We actually tried that with 4 one liter bottles of ice, did not work. But you'ere right about the grow room temp, get that under control and there should be no problem.
Add chlorine to your res every 3-4 days and I bet your cloning works again in hot temps.
Usually around 6 weeks... Sometimes earlier depending on what's happening in my flowering area...nugmaster
Nice shot of the all the soldiers lined up. How long will you let them veg before you flip 'em?
