I bought some cheapo plastic pots to put my cloth pots into..(Nevada High Sierra Summers are Brutally hot..Sunscreen in place will stop about 20-30% of the rays.)
I left one 5 gallon black fabric pot un-shielded..Really no difference.
I must water 3-4 times per day and like you..my pots are full up with roots..
August will be even hotter and I may get one of those personal mister things to hook up to the hose..
You can see in the background..the grass is already burned out..even with an automatic sprinkler (hard to get water down deep in clay soil:()
I only grew a few outside this yr for shits and giggles..HOWEVER..I see a ton of hash just waiting this fall..LOL
Been using Capt. Jack's Dead Bug Brew every week..so far, so good..many have tried..and many have died trying to chomp my ladies..LMAO
They are so chock full of pre-flowers..the harvest should be amazing..NOTHING LIKE THE SUN FOR FREE LIGHT!!;)
