Bummer, you live where the Helo's fly. Aloha
Get Legal and No problem as long as you are in compliance.
Pop up an open green house to cover your grow. Unless, you are like me..to many neighbors. So, force to do indoor.
What Island, Big Island?
What LED lighting to use....hmmm there are so many, good and bad. Could you give us more info on the size Tent, size of your grow you wish to do? Then we can give you some ideas on what may suite you and your grow.
I would recommend Area 51 LED grow lights.
As for wattage, how many watts your going to need all depends on how big your tent is.
So, how big is your grow tent, sir?
