Hi
My cuttings once rooted went into cups and last week moved some into 2.5Q grower pots and back into plastic bin with plenty of humidity. They look great and many leafing out. My question is low long do I leave in the bin before getting them ready to go outside? I know this is the tricky part and would hate to see them fail and concerned about mold if I leave in humid bin too long. Thanks for all the great help

Forgot the pictures of the plants. Thanks for the advice!

You could put the whole bin outside (assuming the temps are staying around the 50's or above) and place it in a shady spot sheltered from rain.  Leave the lid ajar and then slowly move the lid to allow in more air from the outdoors.  The idea is to transition them slowly from the humid conditions of the bin to drier conditions outside.  After that you can slowly transition into full sun.

I've got some I'm up potting and moving out now. They are considerably larger than yours. Last year I was moving them up as soon as the roots showed at the sides of the cups. had to be very careful of the fragile (white and juicy) young roots. I worried then because some of the roots were turning tan and seemed to be shriveling up. Due to space restrictions I had to leave them in longer this year and the root mass is much bigger, and, the roots are smaller (tan) and seem a lot tougher. The plants certainly seem healthy. So, I guess the shrinkage is part of the aging process, and, there are advantages to leaving them longer. See this thread.

You don't have to move them all up at once. Pick out he ones that have both roots and leaves and as Rewton said, move them into a shaded, but lighter spot. The keep an eye on them. If any start to wilt, move them back in. But some do appear to need more light than they are getting.

I am in the same situation, except when my cuttings showed roots, I uppotted them to 32oz plastic cups of 100% perlite.
Should I uppot them with a soil mix (70 mix/30 perlite) and back to the humidity dome?  Or do you think they can be uppoted to soil mix (70 mix/30 perlite)
and begun to be brought outside and acclimated?  Quite a few are showing lots of leafing out and lots of roots in the clear cup.  Thanks.

Bump for an opinion.  Anybody?

If you got roots there is not much need for humidity. I like to pot them up in pro mix and keep in the shade outside. If your cuttings have only leaves then humidity is required until roots form.hope that helps

As mentioned, look for a nearly root bound clear cup before setting them free.  They are very fragile to temp/humidity changes right now.

Thanks all and very helpful. I am trying a few different variations on potting techniques to see which yields best results.

To be honest with you, I have never used a "humidity chamber"', when my cuttings get some good roots on them, I pot them up in a 16 oz. clear plastic cup and put them in the shade. I live in the south, so I guess we have enough humidity anyway. This year ! I have had good luck with my cuttings... Hope everyone has good luck! : )

Thanks Brian and Frank.  I remembered reading that roots that were formed in perlite high humidity were different types of roots than those in other planting media (mix, dirt,..).  I didn't know if I needed to ease the plants into a soil-based mix and or a less humid environment.  I think I will let them mature a bit more, then right into a 70/30 mix.  In May, I will begin to ease them out of the humidity dome and into their life in pots on my deck.  Thanks again for the help.
