perhaps because they dont have enough roots to support the green leaves ...

did you check if they had roots... or did you just go by the calendar???

did you harden them off upon removing from the humidity chambers... or just remove them.. where did you put them after removal???

that the best i can do.. with the total dearth of info provided.....

ken

did you put them in direct sun?

Thanks for the responses. No I didn't put them in direct sun and I haven't checked their roots yet, but they have been in an enclosure. I took them out for a few hours and they wilted.

That suggests very little or no roots because as soon as you remove them from the enclosure all moisture is lost! and they have no roots to take any water in. You could try growing the cuttings in clear orchid pots so you can see the roots develop without having to disturbing them

i actually used pint water bottles... so i could see roots ...

used a sharp razor to cut drain holes on the bottom edge ..

you need to harden off plants before significantly changing any plant cuture variable ...

e.g. ....if you have cuttings in a humidity chamber ... for 3 days.. you crack the top open .. then for 3 days... you increase the opening.. then after a week or so.. you remove the top.. but leave them in there.. etc ...

if i actually saw your set up;. i might make suggestions ....

you cant just take the babe from the incubator and hope for the best ...

same with sun.. wind.. heat.. humidity ... etc ...

ken

this is the humidity chamber i used

when the time came.. i reversed the bag ... and manipulated how much air i allowed in ...

I pulled one plant out of the soil today and they have a lot of roots. I will try hardening them off slower.
