Water rooting cuttings. Advice welcome

My other recent cutting rooting was done with bags for humidity. The leaves where very fragile and moving to open air stunted my figs and killed several pomegranates.
I upgraded to a dome setup and I have remarkable growth on the surviving pomes, I have not yet decided how to or when to transition them again.

I bought the tub with clear top just so I could enclose it but decided against it at the last minute as I think the humidy will stay high enough due to the walls and I was unsure about the added heat could cook them.
