Kushash is correct. You shoukd be worrying about much more basic things.
basic grams per watts

Hey i dont let anyone stop me either but many struggle to dry bud and that really fucked up the system too. Peeps with wetter boveda style early jarring, it all just made gpw complicated except for a few who understood better
Man there are so many variables like strain, temp, air flow, what soil you use and the nutes, the ph and ppm, pulse just you being in the garden maintaining the plants with topping, LST, HST, defoliation.
So I wouldn't even start guessing how much you would get with grams/watts untill you've done a grow or two

5 pound atleast, roughly 1 gpw and thats an ok grow, 2 gpw, 3 gpw, if you got the greenthumb

I had right about 1gpw on my first grow, growing one plant. I’m only on my second grow now, have more plants this time and yes half the veg. And I’ll give everything a fair shot, but I really don’t know if I like the idea of the more plants/less veg/smaller buds type of growing. I also just really like the way a tent looks filled with one plant.
And unless we are talking the same strain and growing medium, I don’t care to compare numbers with anybody else, pointless. Might show they have more money to buy expensive equipment, doesn’t mean crap about growing skills

GPW is more of a large scale clone growers thing. Growing small plant numbers from seed in a tent is hit or miss.
You are working with a small plant count, and unknown phenos. Its more of a balance of your space, how much stretch, flower time etc.
Out of 12 reg seeds, i usually keep 2 that are growing similar after showing sex, then flip to flower and see what happens.
Got .5 gpw last time, hoping next is better.

Trying to cram 2000w into a 4x8 is definitely pretty hardcore. There's going to be a limit to how many grams per square foot you can fit in there that's going to bottleneck you at some point as well. Your plants need canopy space to absorb more light. You can't just dump an unlimited number of watts into a plant and get it to produce more. It'll just bleach out instead. And man is 2000w gonna get hot. Cool tubes will probably not be optional. My first grow was in a 4x4 with a 400w HPS and the adjoining room got pretty toasty. One of the big reasons that people choose LED over HPS is that heat is electricity that didn't get turned into light, and LED's waste a lot less electricity on heat than HPS bulbs do. Not to mention that there are only certain colors of light that the plants can use (PAR) and LED's produce only those colors while HPS/MH produce just one broad spectrum.
Also, if noise is any concern to you, remember these exhaust fans get loud but also getting a bigger exhaust fan and using a speed controller to turn it down can move the same amount of air with less noise.

Depends on strain, many breeders and seedbanks share their g/m2 numbers.

I run straight hps for veg and flower ....my room is larger but I am using 8x8 of it now and heres me lighting
1000w ....400w...400w...400w...150w
I would consider a few things before buying two 1000s ....will you more than likely be upgrading from the closest space after this grow ?
If not I would run 3 pc 400w spaced equally with at least 500cfm exhaust and a fan blowing length wise under lamps ...
But if you plan to upgrade your room to a bigger size then I would consider buying more lights instead of the 2nd 1000w ....maybe 1000w and 2 400s or 3 pc 600w that way when you upgrade you can cover more area ...
Just a thought but good luck with your grow !

Your half right!
Your getting there! Read the following..
I say the GPW thing is really useless.
Look at it this way.
Growing method is the real key. SOG kills gpw!
Taking different light strengths and different size grow area's, including different growing styles.
You can produce as much as 4.35 grams per watt. This was done in a 2x2 ebb. It ran 4 inch Rockwool cubes and had 35 plants in it.
High yield strain and each yielded an average of 32 gr. 250 watt HID, plants flipped at 8 inch's.
Now up to a 4x4 and 64 plants in soil and 1 gallon pots (Plant Warrior pots)
600w HID
Same flip size, same yield average.
3.4 gpw
Grams per watt is basically meaningless...
Yes sir's! It took several dial in's to do this.....It can be done.
You should see what a rotating garden can do!

Now I am seriously impressed. I really want to see some pics of that run please. And other than SoG, what factors do you believe were most responsible for hitting that level? What strain was that BTW? Details my friend because I want to replicate those results, or even close.

A agree that GPW is useless as a metric. Just changing from HPS to LED causes the numbers to be apples and oranges.
Something along the grams per square meter per year. I would even say that veg area should be counted if separate. Now that's a metric that would allow grows to be compared regardless of style, strain, lighting, veg time and such. Then one could factor in the cost to produce the grams.

2.4 pounds in a 2x2 with a 250 hps? I find this hard to believe.
