Nice...I have been meaning to give aero clonning a go for a while now since there have been some issues with soil born insects, or fungus, when useing perlite/vermiculite, or potting mix, or even rock wool. Aero just seems so easy and logical...no need for those expensive mediums either.
I suppose in a large tub in cooler area's a fish tank heater adjusted appropriately would be good. Or simply houseing ones areo clonning tub on a mothering box, or warm area would do...obviosuly with the appropriate lighting above clones.
One alternative approach I have seen is instead of useing a lid on a tub, one could use a thin sheet of styrofoam with holes in it which floats on the water. I guess because it floats, if the water level drops, so does the styrofoam meaning the clones always have their bases submerged.
I suppose also, one other benefit of aero is because of the water, humidity levels remain high meaning one doesn't need a humidity dome. Not that I have used humidity domes with conventional clonning...but do you recomend a humidity dome?
