You gotta grow sativa. But if your looking for a more couchlock/pain killer healing kind of weed then you need indica. But indica does bad outdoors in HI. You need to grow some indoors if you need indica. Otherwise, grow some monster satvas outside!
Btw, atttiude seedbank is good for seeds, also, seed boutique has the best prices. Dr chronic seedbank is also good I hear. Just google any one of them, and youll get results. I would reccomend kc brains 33 as a grow for hawaii, its a big sativa, very mold resistant. Also arjan's haze #1, I heard its a huge sativa, and I am pretty sure its mold resistant too.
Or just look around the seedbanks, you might find a indica/sativa with decent mold resistance, you never know, just research around brah.
