Well, the cooler thing seems like it isn't working out all that well(Dad says it might "cost a fortune" to run it, though hope isn't all lost) so I'm thinking about turning the greenhouse into a lowland hothouse. The thing is, during the hottest part of summer it could get 110F-ish in there. Keeping it humid wouldn't really be a problem though.
Does anyone here have any advice? I'm worried it may be TOO hot even for more extreme lowlanders.
It would be great to hear from some members with more experience growing lowlanders.
