ya its 101.5 in my back yard as we speak/ or should i say as i type / hehe /deep watering let it soak in /its why i use the old trench watering / hopefully it wont stick around like it did last summer

i just looked at the long range for the next 10 days. more of the same for the kc area

yeah i hope yesterday was the worst of it / my basil likes this heat me and my maters dont / hehehe

I am using evaporation cooling in my high tunnel. It is working great. I am sure it would work outside too. Yesterday it was 106 outside, at the start of the cycle it was 97 degrees in the high tunnel. By the end of the 2 minute cycle, it was back down to 91 degrees. I have 6 spinner sprinklers that run for 2 minutes and shut off for 10 minutes. They have been running from 11 am until 7 to 7:30 pm. They tomatoes are all blooming now and I am seeing lots of them taking!

I am surprised how well it is working.

Jay, years ago I read here about misting used outdoors in the Southwest desert to cool tomatoes, but I don't know details (I don't think we got many details) except that the growers (gardeners rather than market-gardeners) were happy with the results.

Are you spraying above the plants, in front of fans, or somewhere else?

Do the plants get damp?

Luckily we almost never have to worry here about temperatures preventing fruitset. Our overnight lows for the next few days were supposed to be in the 68-72 range -- which is unusual -- but this morning they've altered that to 68 two times and the rest of the nights much cooler.
