Great looking cab. I don't see why you couldn't make the same thing.
Stelthy is a great grower with a great cab - this is in no way a dig at him, just a pointer on what it takes to hit 1lb with a 600w. His first grow started 11/24 and ended 4/11 yielding 9.3oz total (post 1838 ). If I did my math correctly that is a 20 week grow. Second grow yielded him 17oz, started 7/20 ended 11/28 which should be a 19 week grow. Lets just look at the second grow:
I'll assume he flowered for 9 weeks which means that's a 10week veg. So that's 756 kWhs for just the 10 week veg at 18/6 (pretty sure I read that was his veg light - would be more extreme with 20/4). A nine week flower is 453 kWh. So instead of a single 19 week grow he could have had two grows, each with a 2week veg and 9week flower.
2week veg 9 week flower = 151.2 + 453.6 = 604.8kWh total
10week veg 9 week flower = 756 + 453.6 = 1209.6kWh total
Funny thing is that people are typically not impressed with an 8 oz grow with a 2 week veg even though it is the equivalent of a 1lb grow with a 10 week veg - same exact $/g...
Personally I should be yielding 12+oz a round so If I had vegged 10 weeks with my 6 plants and had not hit 1.5lbs I would be disappointed - I have a larger space than he does though, not sure how 1.5lbs would have fit in his cab - what he managed was a crazy yield for such a small area.
