With the right grower and strain combination..
They don't exist. Aluminum is an expensive commodity that isn't going down anytime soon. You could build one for about $150-200 easily enough though.
50w per square foot?

Most growers do not hit 1g/w with HPS. That is a fact. Hitting 1g/w with HPS is very tough and you must have the right strain (and probably run more than once to figure it out). You think 1g/w is common with HPS? It really is not. If you are hitting .75g/w with HPS you are doing VERY good and probably have your shit dialed in.

This is what I'm betting on. With my setup, 30W/ft² of CDM is doing pretty well, so I'm thinking it's a good benchmark for a COB fixture.

Finally someone deflated the high gram per watt hot air balloon claims - 1 gram per watt is very uncommon around these parts with those running 4k hps systems in organic soil with a desirable strain and those growers have been doing it for years and would consider themselves "professional"

Whats a desirable strain mean?

Wasen't hid sizing supposed to be something more like:
2x2 - 400w
3x3 - 600w
4x4 - 1000w
?
2x2 - 400w
3x3 - 600w
4x4 - 1000w
?

A 400w HPS really needs to be in about 6-8 sq ft to be happy, at least all mine did.
I've grown with a 400w hps at about 53w per sq ft and a 1k hps at about 62w per sq ft with excellent results but never over about .6-.7 gpw. I also never grow less than a handfull of strains and at that point in time was running about 30.
My new grow is on day 26 flower, a 2x2 cabinet with about 56w per sq ft of CXA3070. So far I think I could have ran them softer but we will see in another 40 days. :smoke:

no, I could cover 6x6 with 1000w, but it wasn't the kind of pot they grow today. Never know for sure if it is lights or just genetics, but yes nowadays, that is kind of the rule of thumb, and if you stick with that guide you won't be dissapointed. Anything after that is just trying to improve on what we all know already works. But still, part of the fun of growing is trying to improve. Especially when you always know you can just go back to hid if you want to.

Depends on who you ask, for hps the typical recommendations are:
2x2: 250-400w
3x3: 400-600w
4x4: 600w-1kw
With high quality LED's it's possible to drop the power displacement 10-50% of a HPS system. Depending on components chosen.
I don't see any point in exceeding 60w/ft^2 with any light source except CFL in my experience. 600w in 4 square foot doesn't produce any more/better than a 400w in the same space, IME.
many breeders now offer a variety of seeds, and even if you live in USA you can buy them. Some strains are sold as good for outdoors, and others are sold as good for indoors, and then it goes on from there, from how tall you want it to how stoned you want to get when you smoke it.
Like this strain I am growing now. It is a short indica and good for small closet growing, but it hates to be topped. The stone is so potent it is more like a narcotic than weed. So I'm looking for something with a little more sativa in it so I can at least enjoy the fruits of my labor before I get pinned to my chair, nod out and wake up hungry in a panic. So a desirable strain is a strain that grows the way you like to grow and gets you stoned the way you like to get stoned. Don't be fooled by the descriptions of the seed vendors.
yeah, what you said. It gets kind of personal because different people grow different strains and use different growing techniques. I was arguing with somebody about something until he showed me a picture of one of his plants, and all I could say was, "Well, that is different. Your plants don't look anything like my plants. They don't even look like the same species!" So what doesn't work for one may work just fine for another.

And nobody yet mentioned how difficult it would be to cool a 2x2 with a 400w...or how expensive I think is he better choice...as well as most 2x2 spaces aren't going to be any taller than 6 foot

Over a period of several years of monthly harvests, the best I ever got from a 600 HPS was 350g. Over the last year, the best I ever got from 600W of LED was 750g and the bud quality was much better. On top that COBs have improved a lot since then.
I recognize that people get much higher numbers with HPS than I did, but the point is they could improve GPW by 2X or more with COB. For those that live in hot climates with expensive electricity, that is great news.
