Hi all, I transplanted my newly rooted cuttings into 16 oz cups about 3 weeks ago and have been keeping them in a clear storage bin in the house. I'm in zone 6b in NJ. I'm wondering if I should be placing the bin with the cuttings outside in the shade, the sun or just leave in the house . Today it is going to be reaching about 90 degrees in my area. 

If they're growing leaves then I would put them in full shade without the bin. After a week or so then put them where they'll receive some morning sun then slowly intro them to full sun.

do not put any plant in a bin in direct sun. You will cook them. 

it all depends on how much root you have right now in those cups. typically, before leaving outside, i make use they are in at least 1 gal container. the reason being 16 oz cup can dry up really quick in 90 temp and i don't want to water more than i have to. yeah.. don't leave them in bin outside. temp inside the bin will be very high.
