I didn't say hydro systems yield more than dirt, I said that they can, so long as the plants are supplied with the same amount of complex-nutrients that they would normally be receiving in soil. I've already stated the nutes she's running: Humboldt Master A & B, Ginormous, and CalMag. This is pretty basic. Master A & B are base bloom nutrients, Ginormous is a flower booster (like Advanced Big Bud), and we all know what CalMag is. She's not running humic or fulvic acid. She's not running any microbial or fungal products... She's not running any molasses or sweetener either... The point I'm making, is that if you're using base nutes in quality dirt, vs her hydro setup, it should be a pretty damn even comparison. The only main difference, is the grower.
And the 700ppm CO2 thing is not a whole lot. Sure it's double the atmospheric level, but weed can use up to 1500ppm... If you want the most from CO2, you run it at 1500, not 700. So if CO2 is supposed to make 30% difference on your yield (who knows if it actually does), then we can say her plants would have a 10-15% advantage at 700ppm, vs your house plants at 400ppm. Another thing you're forgetting Irish, is that temperature affects the metabolic rate of a plant. The higher the temp, (up until a certain point of course), the faster the growth. So realistically, if your plants aren't stressing in 95-100 degree DAILY temps because they now have LED, then they should be growing at a faster rate than plants grown in an 85 degree environment. I've had plenty of HID rooms at the 95 degree level (and sometimes over), when my CO2 had run out or I forgot to replace the tank, and my plants have always been just fine. The only times I ever had a problem were when the sprinklers would clog at the same time, or I forgot to top off the reservoir. Either that, or if the room ran at 100+ for more than 12 hours (one time it stayed over 110), I'd have problems.
Anyhow, 3' x 3' is about the same area as the 2, 126W lights above the system. Even though our systems are 2' x 4', the plants grow to a space of 3' x 5'. 2 lights cover 1 half of the tray, 2 lights over the other. So the 2, 126W occupy about 3' x 3' with their coverage area, meaning 28W per foot. As far as the extra light, 1 more was added in recently over a plant on the other end of the system from this plant. Light doesn't shoot out in all directions with these lights though, so there isn't a ton of overlap from one light to the next, meaning one half of the plant gets light from 1 unit, the other half gets light from another. Regardless, you'll see what I'm talking about soon enough when you do the comparison grow. And no harm done brotha lol. This is an energetic debate, and nothing for me to get upset over
