Hi,

I was tempted into buying a mini-greenhouse thing which is basically
plastic feet and spacers, plastic coated metal poles and wire shelves,
and a plastic bag with a zip in it to go over the whole shooting
match.

Just very impressed at how it keeps everything hot and humid, and
wondering if it can get too hot in there.

It can certainly get too hot. I roasted several trays full of begonias
one year. That taught me to keep an eye on it and to take the plastic off
on warm days.
