Conclusion? Plants that have small hairs on the leaves (like cannabis) CAN hold water which can concentrate sun and cause burn spots and even spark a fire if the plant material is dry. Suck on that.
don't water your plants in the hot sun, they'll catch on fire!

complete and utter fail.

Im being serious while you make yourself look like a douche. Controlled expirements were conducted which proved that water droplets can burn plant matter. Its right there in plain english, why do you keep arguing? Ok so it didnt happen to you, that doesnt mean its impossible.

"...These experiments found that water droplets on a smooth surface, such as maple or ginkgo leaves, cannot cause leaf burn. However in contrast the team found that floating fern leaves, which have small wax hairs, are susceptible to leaf burn. This is because the hairs can hold the water droplets in focus above the leaf's surface, acting as a magnifying glass. The latter not only partly confirms the widely held belief of gardeners, but also opens an analogous issue of sunburn on hairy human skin after bathing.
"In sunshine water drops residing on smooth hairless plant leaves are unlikely to damage the leaf tissue", summarised Horvath and co-authors. "However water drops held by plant hairs can indeed cause sunburn and the same phenomenon can occur when water droplets are held above human skin by body hair."..."

Lmao that is just wayyy too funny kaender. I would rather go with my personal experiment. It showed TRUE results.

It's the uv rays from the sun that burns shit not the outside air temp. The uv gets over 12 here and we have trade showers all the time. I have seen it rain while the sun was shining and the plants have NEVER burned. The uv index in phoenix got up to 11 today and it got to 12 here. It rained for about 30 min earlier now the sun is beating down on my plants. They aren't burning.
