Weening rooted cuttings to ambient humidity

I made a couple of Salvia cuttings, by taking two-knotted stems, dipping the lower halves in indolebutyric rooting powder, then sticking them into coffee cups filled with moist potting soil. Then I put them into a tabletop greenhouse, with indirect light, at 100% humidity.
So far, so good. Two weeks have passed and one even sent out a root in MID AIR, sticking out as good inch. The cuttings made it and probably all rooted.
But the real problem is to ween them away from the (in the long run harmful) high humidity to ambient livingroom humidity. This is usually where things go wrong.
Does anyone have a good schedule for weening rooted cuttings away from the greenhouse and onto the windowsill?

i have no real expiriance with such thins but as far as i know they were supposed to be out of the tent at about two weeks...
the humidety needs to be high only untill roots start to form (to avoide moisture loss from the remaining leaves on the cutting) so about two or three days after rooting actualy starts i'm guessing it can handle a drop in the humidety and then three days later it should already be out of the tent...
the most common mistakes with clones are usualy over watering rather then drying out. at least that's what i've seen with cannabis growers

Has someone gotten you a clone yet? I hope you're doing well with the war over there

Can you host me next?
But back on subject. I try not to let them become dependent on high humidity from the get go. Weather i leave the lid to the chamber ajar or have no lid at all, i just try to keep the soil or rooting media moist.

Might I suggest LSD and glowsticks? For 12 hours they'll have not a clue you locked them in the basement 
But yes, I can see that sucking, i'm very fond of privacy myself. You're doing good work tho offering them shelter.

Hmm the humidity does give me a near 100% survival rate, but the weening is when the dying starts. If I can optimize the weening I'm probably looking at a survival rate of over 4/5.
Salvia roots great in moist potting soil btw, in fact it roots in humid air itself! How is your survival rate with your low-humidity regimen? How much foliage do you leave on the cutting?

I leave nothing but the two smallest leaves. I actually root in water normaly. Take like five or ten cuttings and place them in a jar of water. When roots strike on them all i take them and pot them up never using a humidity dome. In the summer months when i take cuttings its relatively high humidty naturaly.

Tried water cloning yet? The reason I ask is with it you don't have to use humidity. Since the cut is constantly bathed in water no domes or tents are needed. You can build one of these for about 50 bucks with hardware store parts.
Water cloning is pretty fast, this is one week later This is day 10 or 12 Different plant but there is no reason it shouldn't work

I allow my salvia cuttings to have good growth before I change the humidity for it. I do this perhaps a little ghetto but I take cuttings like this:
1. take the actual cutting, always be careful with using sterile knife and such 2. dip the cutting in rooting hormone 3. put it directly in ordinary potting soil (I use a dash of vermiculitte in it as well) 4. Put a jar over the cutting, if the cutting is 5 cm over the soil I use a glass that i 10-15cm tall 5. wait until cutting root and starts growing, make sure its moist and sometimes take of the jar and mist the cutting. 6. when the cutting is so big that it either gets crowdy with leaves in the jar or it reaches the top of the jar then I remove it. I try to avoid getting a stem that is bending. 7. The cutting will loose some leaves when moved to a lower humidity and turn black and brown in the edges this will be better in short time, misting is done twice a day if possible.
I usually has a 100% survival rate on my salvia cuttings and I have taken estimated around 100 cuttings this way.

maybe it's not the RH that's killing them though? maybe you're too paranoide of them drying out and you water them too much (a newly formed clone doesn't need much water, having almost no leaves and new roots that arn't capable of using all the water in the pot!) which suffcates the poor clones and they wilt away...
could you describe what happens in a failed clone... does it simply wilt? does it rot? does it dry out? does its leaves fall off?

Oh no, I learned that lesson early on! Leaves have to sag a bit before watering, and keep aerated soil at all times!
I clone without real leaves, I found this to work best.
I take a stem segment with two nodes. The bottom half + node gets dipped in an auxin hormone rooting powder and put into moist potting soil. The bottom half works, no prob with that.
The top half's node typically has two tiny shoots, leaves close to 1/2 inch at most.
Then it all goes into the contraption, with a moist towel to keep humidity high enough so they do not need watering.
When I take them out, the tip of the stem tends to rot its way downwards, even if you amputate well below it to prevent further rot. When this moves below the soil-line the roots are affected and thats usually the end of that. This is how I lose some clones. I still have a 1/2 success rate but I'd really love it to be 9/10, and judging from the eagerness with which it roots this ought to be achievable.

then if anything its high humidety that's the cause i would think  insted of drying out it keeps on rotting?
i've seen it happen with my pineapple sage but it would stop at an intersection (although the rest of the plant was doing fine...) it was like some branches would abort  i had a bad case of mites that ended up killing my poor sage...

It shouldn't work for salvia because they hate having their feet wet. Salvia likes dry, well draining soils, and sitting in water won't make them happy at all. Its a very finnicky plant.

I never used the rooting hormone by the way. Unless its just something you always have or whatever, you could save $$ by not using it. Anyways I would keep them out of the greenhouse for about 1/2 the day for a week after they were established and then just spray the hell out of them as many times as I could. Then gradually reduce the # of sprayings. Salvia's a tough plant if its healthy.

I recall reading a thread on here a long time back that had comparison pics of rooting clones via different methods.
Let me see if i can find it again.
Here is one. Not what i remembered, but maybe helpful?

To ween them (if the covering on your greenhouse is plastic) just poke a few holes in it to let air in. Then a few days later poke a few more. Keep doing this until the plants don't need the plastic anymore, but make sure you don't make the holes too big at first. After about 10 days or so you should be able to take the plastic off all the way. I use 1 or 2 gallon ziplock baggies to cover mine and they work pretty good. These cuttings were done that way and are about 3 weeks old.

BTW that rot that moves down the stem is bad news. Once it starts you might as well scrap the cutting. It gets into the cutting through the soil and I think about the only way to prevent it is to sterilize your potting soil before putting the cutting in there.

Ah, you're using tops!
I'm mostly making mid-stem cuttings like so:
[] oo [] [] [] oo []
where top and bottom are cut with scissors , the bottom node stuck in soil and the top one shoots to form the plant. This way one stem full of nodes yields many cuttings at once, and it does in fact work.

as far as i know all sage roots aggresivley  and i guess it's as close as i can get to sally.D... i have no idea how similar they really are but from what i know they're close...
it was good practice anyway (now i know not to put my sage outside since it will no doubt be consumed by mites in not time...)
