I get 99.9% success with this formula in a hydro cloner. Per gallon
5 ml cal/ mag
2 ml general hydroponics rapid start
2.5 ml dyna grow KLN
6 ml clear rez
PH 5.5 to 5.8 that's it
I cut my big leaves to lessen the weight of them and to keep from covering the tops of the other clones

so you dont spray the clone just the inside cover?

Yep. Just following DJMs method.
The leaves do get kinda wet... from humidity....not from being sprayed.

Hi XD,
I'm an old timer and have cloned for years, but I'm having some problems in my new location. I live in a cool humid place on Washington coast. Because of the humidity...when I take cuttings, I don't even need a dome.
But the problem is that because the cuttings can absorb moisture from the air...they don't bother growing roots.
What I do is to put the rockwool cube into a solo cup of coco and start feeding them lightly. In short, I treat them as if they had roots. The presence of nutes eventually kicks in and roots grow but I'm talking a month...
If you live in a really humid place...maybe this will help.

By day 3 to 7 what your humidity should be at. I thought that how they grow roots absorb moisture from the air thru their leaf to grow roots

XD,
I re-read your post and yes...the plants absorb moisture from the air. But what I'm suggesting is that if there's some mild nutrient present in the rockwool...that the plant will sense that and have a second motivation to grow roots. It seems to be working for me...but I do have one die occasionaly...

This paper has become my bible for cloning. Here's the executive summary:
- It doesn’t matter from where on the mother you take the cutting
- Leave 3-4 leaves
- Don’t cut the leaves
- Use 0.2% IBA gel
- Use a humidity dome for the first 5 days
"Vegetative propagation of cannabis by stem cuttings: effects of leaf number, cutting position, rooting hormone and leaf tip removal"

I expect there will be disagreement due to tried-and-true methodologies that are antithical to the conclusions in the paper, but take it up wth them. I'll go with science anyday.

9 days. I'm satisfied with progress.I've been running my coco grow DJM style.
Figured I might as well try his cloning method.

He does this in 10 days.

100% rooting.
DJM Coco Trees method.
- big cuts, over 6 inches long from healthy moms
- tips cut back 30%, 50% on large fans
- soak cuts in phd tap water over night to assure they are well hydrated
- soak 2 inch rockwool plugs in 350ppms worth of base nutes and a ph of 5.7 for 30 minutes
- flush sheets with a fresh solution of the same strength and ph
- shake about 20-30% of water out of plugs, do not squeeze them, but swing them like pitching a baseball
- dip in clonex and put in plug, not using the premade hole, but right off to the side of it (premade holes alow to much oxygen in)
- put 10 cuts per dome, never more, overcrowding is a nono with clones and will lead to rot, long root times and inconsistent temps and rh) I take big cuts, if you take small ones you can fit more, but you don't want them touching leaves
- put them under t5, kept 3 feet away, too much light slows rooting and stresses plants, they want defused lighting as they cant absorb bright light without roots
- keep temps IN the dome between 78-80...I use a temp gun to dial in the temps for the first day or two..the proximity to the light, the strength of light, heat in the room all play a factor in the temp in the dome, so one needs to dial that in until it sits at 80..in cold places get a heat mat with digital thermostat, put the sensor for the thermostat in an empty plug in the dome and set the mat to 76, that usually puts it around 80 in the dome..but again , many variable effect that
- I spray the inside of the dome only, never the plants, and keep the dome beaded until day 6 or 7 when I see roots...at that time I open vents slowly over the course of 3 days and by day 10 and are ready to transplant
- I never water plugs after the initial soak, you want them moist but not wet or dry
that's about it...the moisture level in the plug, presoak overnight, nutes in the soak water and keeping temps around 80 are the 4 crucial elements...dial those 4 in and you will never have issues with cloning again

I like sesame seeds on my sushi. 
And....rollin a few in mykos before slapping them into cups o coco.

Oh yeah.
For kicks..(consistency)...I made all the soaked cubes the same weight before inserting clones.

...or you could be developing OCD. lol I like the "breaded" cube thing with mycos. And you cover the clear cups with opaque ones...right? So you can peek at the roots. I'm gonna start doing that.

Lil bit? I was born with OCD. Prolly why I was slaying mainframes at 19.
I dig the clear cups for sure.
4 holes on bottom edges of all cups. I just melt at angle with lighter. Too brittle to cut.

How do you like that Vitagrow Antiwilt? I've used it in the past. It's from American Agriculture the oldest hydro shop in Portland Oregon. They've been in business since 1982. I also use VitaGrow nutrients and have for years. I can walk there from my house in ten or fifteen minutes. It's the only hydro shop I'll go to.

It's good stuff. I mix it up as a dip when taking cuttings.

Well I should have cut some air holes. I took them off for a few minutes a day, not enough fresh air as the bunch (had another) ended up with mold on them.I am trying cloning in some perlite and vermiculite with water in the bottom and a hole in the cup just below the end of the cutting.
Maybe a little less moisture this time. I am also trying a coco and perelite mix. I have a 7W or a 15W 5000k light on them rather than just diffused daylight. Two from my plant two weeks into flower, three from one in veg.

Update. Same results on second batch. I did need to dip each in mild nute solution a few days ago....the cubes were getting a bit dry.
