Your still like really not getting it, and way over exagerrating the numbers (he only vegges his clones 2 1/2 weeks). Assume in your 2000w room you harvest every 2 weeks... You cant be vegging your clones in that setup because you maintain constant 12-12... This is a "flower room" So you veg your clones to a respectable size (1' usually) in your "clone chamber" then put them into your rotation. This way your comparing the GE ratings of the 2 setups and not the Whole Garden GE rating (read your own post you quoted)
"The secondary additions to the GE formula would be for the "Whole Garden GE Rating" which must include time spent in cloning and in veg. Figure it out the same way, with days spent under cloning lights, hours per day, and add those totals to the watt usage before dividing. This will give you a much lower rating than the standard Bloom GE Rating, but is more accurate for SCROG gardens, and anyone who is involved with extra vegetation time."
Considering both setups would have the same clone chamber its effect on there individual Whole Garden GE rating would be the same either way so its easier to just compare the GE rating.
Your trying to compare one setups Whole Garden GE rating to anothers GE rating though.... And I underlined that portion because it says about 1 is a good benchmark for regular GE and this setup reaches 0.92 But it says your Whole Garden GE rating will be much lower (how much is much lower) in that case 0.62 could be not so bad.... I'm not even going to go into the fact that you could run that clone chamber for about 1/2 of the power cost of the cooling system your not having to run with LEDs.
Either way that guys setup was hardly as efficient as it could be and he still got a decent result, and I don't want to argue anymore in this girls thread lol. LEDs should be arriving in about 3 days I just germed a couple Fem Super Skunks from G13 and will get my little experiment going. Its no question that LEDs will be the lighting of the future whether its 2 or 5 years from now (suprised if its longer) But theres no reason why people shouldn't experiment with the newer technologies in different configurations to see if the time could in fact be now.
