I thank you for your words of encouragement, but I could have easily achieved that with only 400watts of HPS I had 2 of these blackstar lights in a 5ft x 4ft area and I think that is adequate, like I said, I'm truly sorry to burst anyone's bubble but my feeding schedule was spot on and plants were all healthy with no over or under watering, all the ph was perfect every time, the temp were at a constant 25C, the light were at 9 to 12 inches from the canopy. Yes the smoke is good but I don't think any better than my past grows . My whole point is that I would rather replace my hps bulb every 6 months and get more grams per watt, it's simple arithmetic. How many bulbs could I buy for the cost of these LED's. It's all about efficiency and the amount of produce for electricity used, we live and learn everyday and at least I have now learned not to listen or take notice of all the hype
