The girls have only been outside for a week now but we just had our first HOT spell. Yesterday, the summer solstice, we breached 100 degrees for a few hours... so I just stayed inside all day. The girls handled it surprisingly well. They still don't drink that much because a week ago they were in 2 gallon containers and the roots haven't filled in all that space yet, but they're working on it. Things are expected to be a bit more seasonal the next week or so.
