best humidity for rooting clones?

this is why you always take more cuts than you need.. once they root you can toss the ones not needed
I have found multiple sources, most of whom make the equipment in question that say no domes. This applies to bubble/spray cloners, not rockwool however.
Essentially, if you are spraying the stalks and it is long enough the cutting will get enough water to survive at normal humidity levels.
Just built a spray cloner so I guess we will see how that works, I will be running it without a dome for the first run.

personally I must suck from all the people with 100% success rates. I can also only kill worms, not raise them. Anyhow once I built a bubble cloner, used no dome, got roots, but upon transplant it was Chopin's funeral march. I agree they're something to it since the top of plant doesnt need extra humidity, but I'm back to what I find simpler since since I suck at both methods it doesn't matter which I work on improving.

Is the plant it come from still in flower, and for how long?

I just stick them in 100% coco out of direct light with a dome at first with the vents slightly cracked. I take the dome off after a few days and the clones never wilt. Roots in a week to ten days. If there is any sign of wilting early on which rarely happens I just mist the inside of the dome not the clones.

I've had a clone in my bubble cloner since Feb 11/12th, 7 others were taken that all rooted with 14 days, the ones I kept have been potted long enough to have revegged but that one just won't root, 
it's now become a point of determination I will get a root lol, it still looks viable wtf?

next time find a healthy mother
prepare a solution of ph 5.5, soak your rockwool in 1 hour to rinse it
throw the water, rinse the cubes with the shower and prepare another solution of 0.6mS of nutrient at ph 5.8.
put your plugs in. check the ph/ec 30 minutes later. you want around 0.5mS(+ec of your tap) and around ph 5.8
now your plugs are ready.
prepare the cuttings you will take on the plant. cut the big leaves at 3/4 and the small ones at 1/2
then cut your clones, insert them fast in the plugs. if you let air go in they will wilt. you must shake each plug by hand before putting the cutting inside, its the secret
if not, they remain too wet= problems
once your plugs trays are ready put them in the dome around 25degree C.
very diffuse lighting, around 50micromoles. let the vents gently open.
if your method is dialed in, you will want to water every 2/3 days. when you water, just pour a small layer of solution in a tray, ph 5.8 ec 0.5
immerse the plug trays in the solution a few seconds. they will suck water without getting too wet
there is no magical method, only you can dial your process depending on your temps/RH.. configuration ..

in this case it's the first time I've have taken a clone this way. I started from seeds, topped and cloned tops which was a miserable failure at 10%rH outside the dome only 1/5 survived. Then I sexed them (edit: the original bottoms), left them in flower 4 weeks to make sure no herms becuase I already had 2 full on herms out of 6, and then revegged for I guess 4 weeks. Once I saw reveg growth I waited for what seemed big enough to cut for cloning. So technically they were all in veg. This weakest one had a thin stem but it's semi-hard wood.

how much how often do you water the coco?

oh it's so difficult! But thank for the details, I hear and I obey. 50 micromoles, what's that in light bulb world? I got a 20W LED bulb I think it's true 20, 25cm above with a white pillow case in between. Does that sound about right? Shit, maybe I should ph down. I tried before a drop of Super Thrive it has vit b in it and it seemed to help but also water seems a little slimey and so I guessed it seemed to help mold too.

I don't water it for days. I squeeze the coco out pretty good so it's just good and damp before using. You don't want it soaking wet. It will stay damp enough under the dome for a few days. Then after that I just use a pump sprayer and spray enough to make sure it's still good and damp. No runoff. Not that wet. How often and how much you spray is going to depend on the environment. Temperature, humidity, etc... which all affect how fast the coco will lose moisture to evaporation. The clone doesn't have any roots at first so any moisture loss in the coco isn't going to be from the clone but from environmental factors.
Many people having issues is due to keeping the rockwool, rapid rooters, soil, or coco too wet when starting clones. Damp is better than wet unless you're using some form of water cloning system.
Should see roots within 10 days if not sooner if the moisture level and other factors are dialed in. Low lighting conditions and a heat mat help as well. I use the top of the T5 in my veg tent. Works great for a few clones.

do you have a cheap luxmeter ? 50 micromoles equal around 3700-4000 lux. it's not much
if your plants are sick i suggest to put the light farther

Thanks. I probably have to start some more so I'll try some of these ideas. The little girl I want most and that's hurting the most is not improving but is hanging in there where in the past I would see things go downhill faster with either too much or not enough humidity. Tho I don't mind it taking longer it does look like success will be a race where she has to make good roots before mold overtakes her.
The white fuzz looks like a mold feeding off dead leaves. Most of the dead leaves were from buds that formed before the reveg. I bet it's even slower because the cuttings are hardish wood.

Saw 20W led bulb listed as 1250 lumen. 1 Lux is defined 1 lumen per square meter. If bulb is .3 m away, lux is 1250/4x3.14x.3x.3 = 1160. The pillow case probably filters 90%, so I'm only 110 lux. If I'm right, I need maybe 3 bulbs and no pillow case. Sounds like too much light?

or alternatively that's one bulb, 1250/4x3.14x(ysquared) = 4000. gives y, one bulb 16 cm away. I guess maybe.

white fuzz on leaves = botrytis
everytime i got it in cloners my plugs were too wet or/and the rh was too high in the dome

the best is to find a luxmeter. it cost 40dols maxi and then you will be able to dial your light distance
plants are very sensitive to excessive light when they are small/rooting
