Like HighHawyn said- temps are key- in hydro 65f is the target, and 75f is about the max. I use bleach in my setup but I don't go organic with it currently. If you use any bennies or organics you should not use bleach, but it really helps you to kiss with regular hydro ferts like dyna-gro and 6 drops bleach/gallon...
Make sure heat doesn't become an issue, I would just consider to make a pvc frame and use some shade cloth... Perhaps you could just surround them and camoflauge with other plants.
There are CHOKE flying over Kihei. Don't they fly outta there? I think so. My mom lives in Pukalani and I can sit and watch those fuckers zooming around all over the place down there.
i'm not complainin tho, there are goods and bads about each island and area 
that's why i love Hawaii and will never leave i don't even want travel outside of state for fear that i might die somewhere else and have my soul all fucked up in china and shit lol. braddah needs to be home. just ranting. on that green house thing, i am imagining a lanai like you said, i used to use the clear plastic roofing over a dog kennel and shaded sides. in your area, i don't think you have to worry about bud rot so you probably wont need as much ventilation as you think. shit dries out in like 2 days there and it never rains! well hardly ever, as you know. k, let me think some more lol, stonded 
I would love some that sun too!! Seem like I get a day or two of sun then rain or drizzle, the rot kicked my ass this winter. But on a good note I don't have to worry about my neighbors seeing my plants. This is the only place in Hawaii that I can afford to buy 3acers. I want a environment control green house dream on about 20 grand for what I want. Going out to my mother-in-laws 80th birthday and she can still smoke with the best of them so will be a good time, choke food. Alohawhat i wouldn't give to get the kind of sunshine you guys get cirE. my buds would be amazing, as it is, with all the rain we've had all winter, i was lucky to get what i did
. What kind of plants should I use though? The plants I have right now are small (cilantro and some chilis). Any certain kine from walmart or anything? I have been trying to decide for 3 weeks where to put these plants. I am completely out of space in my box. 4 plants and 3 clones... I already topped about 3 times because they are too big. I need to hurry lol. thanks guyscan, you just gotta watch out for wet/mould conditions, as the buds get more even light from scrog and they will all be phat instead of just the top cola, so the closer they are together, the more possibility of bud rot/mould conditions. i have a friend that always said if he could grow outdoors legitimately, he would use his DWC and grow the biggest plants he could, which i think could be big, because i have seen his indoor dwc and it rocks, so much quicker than soil. good luck.
