Decide what day you want to plant. IDK the light cycle in Hawaii, so don't know what would be the best day to plant. Look at an almanac, and get the sunrise/sunset time for your area. Remember, plants trigger 1 hour before sunrise,till one hour after sunset, so add 1 hour to the light schedule for that day, to the morning, and the evening. Set your light timer to match that, and leave them there for at least 2 weeks and then when you put them out, they shouldn't flower, unless the days are just too short in your area. If it's less than 18 hours(and it prollt is) drop em' down to 18 hours for a week or so first, then go down to your mark.
I have had plants flower on me more than once, and have used this method for the past 2 years and havn't had 1 flower early on me since.
