cloning in coco ??

ran out of space in aeroponic propergator, and ran out of rockwool cubes so i got the small square pots and filled them with coco [slightly pre-fertilised] and stuck my cuttings in them then in to humidity dome, experimental rly although i rly need them to root otherwise ima have to buy them at 5 or 6 pound a pop
Wot kind of chances do you guys giv them if any?
How long do you think it will take?
And any tips [or insults] are welcome

In MY EXPERIENCE, coco works well, at least as well as peat pucks or rooting cubes, the only problem I had was blue green mold growing at the cut tip and around the base. I threw everything out, got new containers, and it still happened, my guess, its completely sterile, allowing the perfect breeding ground for fast growing bacteria, mold or fungus. My suggestion, if you were to use coco for clones, inoculate it with beneficial bacteria or use hygrozyme, something that would stave off bad pathogens long enough for the clones to take root. Rooting times depends on the health of the mother plant, its rate of growth, strain, and ambient conditions which should be very humid and warm for the first 3 days, while opening the humid-o-dome (you have one right?) for about 15-30 minutes 3 times a day for the first 3 days and then take it off altogether after that. I've had roots appear in 10 days, but, I would suggest buying a bag of rooting plugs, they are 25$ for 100, thats 25 cents a piece, totally worth it as I have like 90% success rate (it'd be 100% if it werent for this fastidious Blueberry Kush strain).
