Hey Norcal, I cannot speak for everyone in Hawai'i, obviously, but I live on the Big Island, where we get tons of rain and constant high humidity ( 60%+), unless you live southern parts or in Kona. But, I would agree as far as alot of guys do grow a variation of "white widow" hybrids, but I have come across lots of strains from indoor growers (primarily indica dom), as well as outdoor growers ( i would say more sativa dom).
I personally run hybrids that tend to lean more on the sativa side, if I don't, my indica dom hybrids or strains that are meant for low RH just bud rot to shit. I personally cannot afford a dehumidifier that would properly do the job, electricity is expensive as shit here in the islands. Get ready for some hefty electric bills.
My favorite strains to grow so far in my climate are: Diesel (from a friend, old school strain), Grape god (tends to mold if I do not watch it and provide it proper aeration techniques), and NL #5. Lol, and I am growin a WWxBig Bud too.
