I had a friend who recently had problems with his home made bubble cloner,well not the cloner but with keeping the stems submerged.He started gettiing some slime on the stems.
After thoroughly cleaning the res and lowering the water level to let the bubbles mist them he had roots in 7 days.Using a very strong air pump makes plenty of splashing bubbles.
His res usually hovered between 65 and 70 but we never thought it needeed to be different from standard growing.
Higher humidity is a must i believe,misting inside the dome a couple times a day worked just fine.
Yeah, I have a huge air pump in there. Overkill actually, if there is such a thing. But either way, great bubble action.. So for now I lowered the water level. that seems to make the most sense of the two options and was planning to keep it like this unless someone came along and convinced me it was better to submerge them.
I dont have a humidity dome though(not yet). I was going to try and do it without one this time and see how it went. I know I have read that a lot of people dont use them. I keep a couple of soaked towels in there and I mist them pretty much every hour... but if this isn't good enough, then I suppose I will be building a dome of some sort for round two.
A couple of the cuttings have already died, but looking at the stem underneathe the neoprene cup I think it was due to my cutting them badly.. I think I shaved too much off of a few of them. Just another lesson in the books I suppose.
