Hey Arthur plants are looking good! I know I'm kinda late to respond to something on the first page but I live in California as well and tried my best to find everclear but no luck. I've also heard iso isn't the safest for extractions. I've found this 200 proof ethanol on Amazon it worked great for me winterizing my BHO I made. Not sure what method you're gonna try but I'd say go for the ethanol instead.
Good luck with your grow I'm doing an outdoor grow as well and one of my plants hermied on me
I think it's gonna hit triple digits again soon.
