You can build a greenhouse with just a shade at the top, try to find something that leaves you with enough lumens to grow but kills the UV

Yes, either shade it or lose it. The UV is at max level between 10am-2am. Some cloudy days no shade is needed. I need a handheld UV meter for gauging .
I forget where you're suppose to check the plants temperature, but if its below 30, underside of leaf, it will be fine I'd assume, the bigger leaves that are near the top will provide shade for the under side
The temperature is 100° today, the plants hold up to the heat. I lost plants due to misdiagnosis, thinking UV damage was a sign of overwatering. Sativa is more sensitive to UV than afghan. Just have to keep things in balance and learn.
