Down here it was over 120 days of over 100* last summer. With like 70 of em consecutive.
It was a badd mamma jamma... Only had a small indoor for a while then took a break for the year.
I am ready for it this year though. I only let my outdoor girls get morning/early afternoon sun, then mostly shady/patchy sun the rest of the day. On exceptionally hot or windy days, I'll take a gallon jug or so, fill it with water, and poke 4-5 holes in the. Ottom with a thumbtack. Then put a hole in the lid, and it'll slowly drip the soil all day--helpng to not let the evaporative processes wilt the girlies.
