Won't they be severely stunted just leaving them in the sun during really hot days?
large plants have more leaves. The more vegetation you have the more evaporation you get. The more evaporation you get the cooler the plants will be. That's why small plants don't do so well in the heat but larger ones do just fine.
That is exactly why I thought I may need it. The climate where i would be growing is very similar to that and so is the terrain. I'd be growing in max sun,no shade at all.
I think the 30% is a good idea for those consecutive 105+ degree days. Hail is also another huge reason I will be using shade cloth over greenhouse plastic.
If you live in a desert environment 10% to 15% humidity plants seem to just survive at 100*F and above with the shade cloth they thrive as others have described in high heat.
I live in a very deserty area like that, have done shade cloth and just straight outside.. the ones without shade cloth always grew quicker and yielded denser nugs.. Just my experience though. They were all in a minimum of 300 gallon holes
I grew in the red dirt of the Kimberly desert North Western Australia.
