5x5 per 1650?
Why LEDs?

Nice I have my lights over 4x4 it's hard to get over 2 lb per 4x4 but in a 5x5 3-4 sounds reasonable

Please, do grace the forum, with a full detailed description of "full spectrum"....

I have enough heat as it is in the middle of the summer. The last thing I need is an inefficient HPS dumping even more into my grow area. I’ll take 2.4+ PPFD per watt, more vertical leeway, significantly lower temps, significantly less electrical usage, and long term cost savings over blasting an HPS any day. In the end, who really gives a shit? We’re all cannabis enthusiasts who aspire to produce great meds. As long as they are frosty, tasty, and potent, the rest is all just dick-swinging, bro-scientifical semantics. HPS lights have utility and can produce great product for sure, but it’d have to be the dead of winter in the far north for it to make any practical sense for me...

Personally cant stand LEDs, had a Viparspectra R900 (bullshit blurple) for ages, only thing it did well was vegging! Built a couple of COB based lights and these did pretty well but after two runs I just couldnt get anywhere near what my HPS can pull.
Over all in my experience I have found LEDs fairly useless, the R900 pulled 420w from the wall with both switches on and my room was always hot, up to 34 degrees Celsius! Put my HPS back in (new bulb obviously), smell is back up through the roof, trichome count is exploding again, light penetration is better! Cant claim its genetics either as every plant grown under these methods came from the same mothers (been running the same genetics for 2 years now)
With my 400w hps and 8 inch extractor running Canna Pro Coco and Canna Coco nutes with some plant magic bloom boost thrown in, I sit at a steady 22-25 degrees Celsius! My yields are also back up to 12+ oz a harvest!
I'm not saying LEDs cant rival HID, just I cant seem to adapt my growing to using them and never saw the benefits or results!

do you live in another universe? one in which the laws of physics dont apply to your grow?

570 wall watts, 2.2 lb.
260 watts.
330 watts.
And I don't even try to max my yields.

18oz @345W left, 20oz @400W right in 7-8 weeks. One plant per light, so not the most efficient way to grow. But 1.4-1.5gpw is entirely possible with LED.
4lb from a DE HPS? I want to see it.

I notice a lot of numbers get casually thrown around online that I have NEVER SEEN actually achieved in person and I've seen a lot of grows, both personal and commercial.
Funny how the claim is 3 a light but everyone is always happy with 2-2.5 from a DE.
Another thing I notice is that new people love to bash on LED while assuming that growing conditions remain constant. They do not; to get the best from LED, you need to run the room warmer to compensate for having less IR from the lighting. Nutrient requirements change, too.
The biggest difference I've seen from the switch is better density and quality. These are harder to quantify but well worth the upgrade.
@DuBR I hear you about wanting to get objective info on LED lighting. High performance full spectrum- that is, white- lighting can be found from HLG, Timber and other vendors here on RIU. Best flowering is seen under lights from 2700K-3500K, at least 80 CRI. They do veg very well also. These lights are far better than nearly anything I've seen from commercial sources and especially from places like eBay or Amazon.
It's important to run the room in the mid 80s for best results under LED. Be sure to get the correct light pressure and PAR values when setting up the space.
Few people understand that pusher props are different than standard types, even fewer know why. Kudos to your dad for filling you in! Jets are better for specific applications but turboprops are still very popular, and for good reason.
Best of luck brother, hit me up with any questions you might have.

So now its 1 -1.5 a light instead of 3 or 4? Or did you just assume DE would be that much increase over your SE a decade ago? Last time you grew?
I use primarily enhanced white. Yes, beefed up with chloro peaks. Including 730nm & 470nm, not limited to 630 + 660 as well.

That's no where near the quality the OP put up. Thats fucking weak sauce. Switch to the bar 8 or get the fuck off the boards.
If you are really harvesting after 7 weeks, you need to be kicked in the nuts. Facts.

No they don't. Not normally.

Be sure to get the correct light pressure and PAR values when setting up the space. ---TTYstick, what is light pressure?
What par values would you reccomend with LED? Tempratures?
