Wondering if anyone has recommendations on greenhouses. I'm going to be growing a small medical grow in Hawaii, just three to six mature plants, but I'd like to grow them rather large -- I'd also like to grow some vegetables in the greenhouse.

I'm interested in letting the best light possible in and something that can withstand the occasional Hawaiian storm. Does anyone have experience dealing with a good greenhouse company?

I have a Hall's Magnum greenhouse 10x 12. It allows me to grow 5-6 plants ( depending on strain.) I found that you run out of room pretty fast so get a size a little bigger than what you think you will need if you can afford it. I purchased a greenhouse one size up from what I was originally looking at am am very glad I went a little bigger.
Be sure to take into consideration how you will be regulating your temps. You don't want your exhaust fan running all day . Be aware of the odor leaving your exhaust vent and if any neighbors are near enough to notice. Consider using a filter or ona system.
It might cost quite a bit to have one shipped to the islands.
good luck
