Any good sites for strains And determining their highs?

Opinions appreciated

Google...

Sometimes I check stuff out on leafly.

but for a list of information on available commercial strains, i'd recommend checking out the seedfinder

en.seedfinder.eu

Yep. Seedfinder is probably the most comprehensive list.
