Another group out of the hot box and this one I left a few days too long, now I have juvenile foliage to protect from temperature fluctuation, must be frost free and not too much variation and temperature spikes.
This is one of the issues with hot pipe/boxes, callus can form pretty quickly (7-10 days in my system) but it does wake the stocks and scions up very quickly, if they stayed dormant it would be easier to handle them for the next two months.
In the foreground some juglans sigilata, 2 on j.nigra and 2 on some larger repurposed j.regia as an experiment, no difference in callusing.
