My cloner is on a reptile room timer...I got timer set on/off every 15 minutes...It cooled the rez by 10 degrees, and I think the roots should be OK receiving Oxy...for 15 minutes.
Actually, I think cutting the sprayers off will have a positive effect.

ugu...great ideas. I have thought of using rapid rooters in place of collars in my units...I use rapid rooters exclusively for germination/starting my seeds. With the exact method you described above. I place seed in R'R'r and spritz once to 2wice daily as needed...when sprout pops out, I place 2" under a cfl with a very small fan indirectly causing a breeze.

I even thought of disconnecting/removing the pump and putting 14" airbars in the bottom. I have had great success cloning straight into hydroton filled netpots...In fact, I clone 3 different ways, right now...trying to master all methods, and I "KNOW" that the clones dipped and placed directly into hydroton filled netpots will root...EVERYTIME!!! the only drawback and reason for my other methods are, that I find
it more versatile to root in peat/r'wool/rapid rooters. That way I can go Hydro or soil/less. With Netpots*, I prefer not to place them in dirt...although you could if you wanted to.

*for your info...You can root/veg (I think they make 1") in extremely small netpots and then put those netpots into larger netpots or ebb tray once roots show at outer edges of small netpot. lw:smokin:
