vince,
hardwood are much more simple. once the top comes up, you want start airing out some. even before you want to air out to possibly prevent mold issue. you leave the dome open 5-10 min at first, the slowly increase the time. at first, you know for sure that cup will have enough water, so if the leaves are drooping, it's due to lack of humidity around so you put the dome back on. later on when all the reserve water in the cup is almost all used up, you want to check and water just a little to perk up the leaves.
not sure how to work with root riot system since i haven't used them.
now with greenwood. thing is little different since the cuttings themselves can dry up, not just the leaves or branches. i assume that i can do the same as the hardwood, but when i did the saome with greenwood cutting, they all died. so i guess i can just simply cut down the airing time. but when do i know that the cutting are hardened enough for the outside? with hardwood, it's already hardened. no issue of cutting drying up.
