Indoor vs Outdoor
I think indoor grow operations are just simulations of the outdoor conditions, just not as efficient.. I have seen a great deal of indoor operations... From the smallest of grow cabinets to full warehouses running 50,000W light systems... I used to grow indoors when I lived in California, always dreaming of growing outdoors here on the islands...
The only advantage I see to growing indoors is that you are in complete control of the conditions..
The disadvantages are many... but to me, the cost is the biggest problem... you have to offset that cost by growing more ganja... Indoor growers are more inclined to growing high yield crops, which most of us know are typically not as potent as some of the specialty crops, like Og Kush for example...
Scientific evidence shows that you can't replace the Sun's light spectrum, especially for the greater range needed during the flowering stage. People grow indoors because they don't have the same luxury we have here..
Another big issue is the taste of the final product when considering outdoor vs indoor... Most Cali dispensaries can tell you that in November & December, they sell way more outdoor grown bud (that's when most of the long season ganja hits the market) than indoor.... and the quality is worlds apart....... But the rest of the year they need to depend on indoor grown to keep the supply up....
