Been hot here too. My tent has been running around 86-88F. No issues, but like Carcass, using lots of water!My box has been running at 85-86f for the last week or so (heat wave) hasn't bothered the plants at all.
They drink a little more (and I don't blame them) but that's all that's changed.
I have no way to cool them down, so I'm glad they don't mind the heat.
As my mom used to say "This too shall pass"- there's a light at the end of this tunnel, but it's hard to see it right now...
Take care,HH
