Well i would rather 2600 watts of HPS lighting over the sun anyday. Maybe if cloudy days didn't exist then sure the sun is better but its not as '' reliable'' in the sense that your not always going to have perfect lighting conditions with the sun. I know in Hawaii its usually sunny but im sure you get some cloudy days too. There's only so much light a plant can make use of and if you have adequate wattage for your area your HPS should do you just as good as the sun. The main advantage of the sun in that its full spectrum. The sun also emits UV rays which some claim do nothing to a plant but research shows it increases potency and resin production. Pretty much what im trying to say is the sun is a better light source than an HPS bulb but if you have adequate wattage for your grow area its not going to make much of a difference. I would rather have full control of my environment and never worry about overcast weather.
The sun in better but you can't control it... so in my opinion HPS is better.
Glad Barney had an answer for you....still strange....was the cotton inside the seal or was their no seal and the cotton in its place? Also forgot to ask you if both seed pack seeds look similar?
I agree to some degree about the sun......but i live in the "sun belt" on the southeast side. The furthest most point south in the US: It is approximately 19 degrees north of the equator. So the sun is powerful more on this island than the others. This also does what you say to the ganja....plus increases the pod or "calyx" size conciderably!
But of course there is a downside when freaky weather near the end of the cycle can cause plants to rot. But inside is not free of troubles. Depending on where you are.....you can run into power outages, light leaks, fried bulbs, ac malfunction, bugs, infra red detection, fires, flood, outside sweltering heat and humidity. No one is free from all theae things....even with a back-up generator! Parts fail! What if you are running at night.....you go to turn on your light and it fries, you don't have a back up bulb and its a holiday weekend and no stored open....you see what i mean?
2600 watts is not much light.....your room can't be much bigger than an 8 x 12. Most you will get from a 5' plant with this set up is 4-6 oz per plant if you know what your doing. Where a 5' plant in this set up can yield 8-12oz. I know these aren't huge numbers by Cali standards....but they only have one season where i can do it all year long. You can put plants out every two weeks, so potentally can harvest 24 crops a year if you are really working it. The smoke is also much more potent than some of the better stuff i've tried from Cali. I mean Hawaiian weed is legendary for a reason!
