You get more trichomes but since they mature faster they don't get as big. You will see what size heads you have when you run them through bubble bags or dry sift screens.
I don't do that, I smoke flowers and only need one hit, haven't needed to make hash for years

that map has nothing to do with ozone depletion.


Ozone depletion is greater at higher latitudes, (toward the North and South Poles) and negligible at lower latitudes (between 30 degrees N and 30 degrees S).

However, cities at lower latitudes generally receive more sunlight because they are nearer the equator, so UV levels are higher even in the absence of ozone depletion.

That's a uv map. We don't get uvb in the U.S.. Hawaii maybe...

Living organisms at high elevations are generally exposed to more solar radiation and with it, more UV-B than organisms at low elevations. This is because at high elevations UV-B radiation travels through less atmosphere before it reaches the ground, and so it has fewer chances of encountering radiation-absorbing aerosols or chemical substances (such as ozone and sulfur dioxide) than it does at lower elevations.

I have no doubt of this, but a bit off topic here what's you're concentration levels of O2 and cO2 at that elevation ?
that i don't know for sure. there is a chart that shows how elevation and O2 affects horsepower in cars/trucks etc. i think it's like 3% drop per 1000 ft elevation.

everything definitely grows slower here. hence treeline is a fixed value at something like 11000 ft elevation.

This was a discussion in another thread... UVB is about 1-3% of natural sunlight depending on several variables such as elevation and location on the earth/time of year and weather conditions. But pretty much all of Earth receives a measurable amount of UVB.

P.S. UVA also causes sun burn.

The link clearly shows UV exposure increasing as irradiance levels also increased.

Also this NASA link about UVB explains how there are many variables to UV exposure. Locations further from the equator experience differing UV levels by season due to the incident angle of sunlight at different times of the year.
But most everybody on Earth is receiving some amount of UVB radiation. Enough to cause sunburn even in the far North regions.
