Because you now looking at it like a mathematician. 1000ppfd at the corners and how much in the middle? Then how high do you hang it? Remember the high the more light wasted to light bleed missing the plants. It's no better than the 600w ones that can be kept closer. All that extra wattage is going towards wasted light not being used by the plants because you need to hang it high so you don't cook em. Try a gavita 1700e and see if you can put it 6" away because that essentially what you would be doing. Mathematically you are correct but practically its a waste.
I'd need a taller ceiling that beast.

Way too much for me. my lil 2x4 makes more than enough. That light can supply my whole block.8' should be plenty
Im planning to get 2 for a 5x10 area lol i better get good sunglassesWay too much for me. my lil 2x4 makes more than enough. That light can supply my whole block.
I think what you need is this; Like long strips, tacked to the top, and just widen out that grow space with the DE units.I'll figure it out , I did last harvest using my 16 bulb 5-5 fixtures at this point I'm NOT giving up on my DE I'm buying new hotilux bulbs and gonna kick ass as I try to always do , with success comes $ so being successful is the the key . I'm done on this subject , got bigger fish to fry . I getting ready to have to deal with state compliance , zoning , banned substances, I have no time to argue apples and oranges . I honestly came on here to help someone who really needs it to remind myself why I love what I do , and still have love for the plant . Thanks for your input .

Have a link to those charts?
I really think par and ppfd only tells part of the story of what's going on. As Aquaman suggest, there's more at play here there not showing everything. It's not only output, (that's a big part) but light (color) temperature is key. Ratio of light frequency.3x3 vs 5x5 for led
better get co2Im planning to get 2 for a 5x10 area lol i better get good sunglasses
For the gavita - scroll aways downHave a link to those charts?
better get co2
What do you figure it will produce yearly?Got two 20lb tanks just need the controller. Going to be a sealed room.

Light color is largely behind plant response, internodes, and various other signaling pathways. ie. chemical messengers.
That's where the LM301H standout from the pack above and beyond the rest of the field. There specifically constructed for this very specific horticultural purpose in mind. I've got some of both setups, so I can see the difference.
Not debate so much as just highlighting some of the key factors that often are overlooked.What are we debating here?
6lbs every 4 months roughly. 7-8 if i go hydroWhat do you figure it will produce yearly?
Yes definitely agree. Thats why adjustable spectrum leds for the win.Best lights =
just adding that ppfd doesn't tell the whole story. The spectrum and behavior of plants under each different color of light is going to be vastly different. Especially when it comes to internodes, and ripening length, weight, and flower complexity.
Lower (color) temps tend to perform better later in the grow, whereas higher (color) temps speed earlier growth, and there's a crossover that occurs dependent on developmental stage in question. So when looking at your light prospects; you might want to take these considerations into account, (not just watts, and ppfd) there's a major difference in how the plants respond to these different spectrums.
These ratio's are key to optimizing plant growth, independent of intensity and ppfd.
With that light and co2 I think you have to go hydro. Soil ain't gonna cut it.6lbs every 4 months roughly. 7-8 if i go hydro
Im optimistic
I'd like to inspect what your speaking of specifically. If it's the color of the full spectrums; I'll agree, but if it's simply adding a bunch of red diodes, I would be leery.Yes definitely agree. Thats why adjustable spectrum leds for the win.
Output better fir yeild, spectrum for quality
