So, are all plants grown outdoor and in green houses stressed the whole time they are growing, which causing them to smell? Even the 15lb harvested lush green plants that were growing 6" a day in their stretch?
Do you mean it's wind that causes the smell? Because I feel wind isn't stress and a necessity for all plants to have a breeze of some sort daily. I've seen and grown outdoor plants 100% healthy, 10lb plants (which an unhealthy plant will never achieve this in your wildest dreams) and she smelled awesome.
Which brings me to indoor growing (because it was mentioned that outdoor isn't the proper environment, even though mj has adapted and been growing for millions of years probably).
Do you grow one single strain each grow? Dial in the environment for that particular plant perfectly, which causes it not to smell?
If not, and you're growing multiple strains, some from different regions of the planet, how would using one particular environmental setting for all the different strains in a single grow room keep all of the plants 'happy" to avoid them smelling?
I assume, or I know for fact, that different strains like different climate and nutrition, and environmental aspects. So if using a singular control for all plants, it would lead one strain or pheno to be not as happy as it should be, causing a smell?
I'm intrigued. I mean, I've had some strains, or rather when I'm using a low amount of watts, that hadn't had a stench that could be smelled easily. Though, my grow is not big now, you can smell it at the bottom of my 100' long driveway.
Have you grown really stinky strains? Diesel in particular? If you've grown diesel and it didn't smell, I'd be certainly worried and possibly attribute that to a negative factor in the grow causing terpenes to go stale.
Terpenes are the wonderful smell we get from plants. All plants have terpenes (or at least most do).
Terpenes can't be tamed. Though, a rose bush will smell more when the wind blows (but that doesn't mean the plant is not happy, it just means the wind is carrying the terpenes smell into your nostrils.) After a rainy day also. Make it rain, right? I've read a lot of your stuff and respect you fully, some of your flowers are fantastic looking also! But I wouldn't attribute a plant that isn't happy to a smelly plant. That I just can't buy. Terpenes my friend, terps!
I do think I've figured out mostly what is going on with a lesser smelling plant. Wind. Fans blowing. I'd reckon a some terps get rustled around causing some more smell. But wind is our friend in growing, it's a natural thing and plants love a good breeze.

These gals stank. Like lime slurpee candy's and fuel 
I think they're happy, they seem happy at least, I didn't even burn the tippy tip of the leaves tips heh, damn near perfect grow (first grow with these cuts and no info on them before I got them btw), they seem to be loving life so far but the terps are farting up a storm

Well you're not alone, the majority clearly think/feel I'm nuts and yet I have proven it over and over and others have applied my methods and gotten the same results and posted it here in this forum,,,,, it is what it is

There are Watts, and there are Watts.
1 gpw is a standard that someone using an HPS bulb can attain when everything is tuned in. That includes proper nutrition, watering, pest control, humidity management, etc.
It's worth remembering that only part of those Watts get converted to light, though; using a lower efficiency light such as incandescent bulbs or an early generation LED technology such as in Mars Hydro, or a higher efficiency light such as Cree CXB3590, will make it easier or tougher to get to 1gpw. Many growers report getting in excess of 1.5 gpw using COBs. For example, in my first indoor run ever, I pulled 21 oz. In a 4x4 with 588W of Vero 29s, and that was after tossing 2-3 oz due to powdery mildew. That was 1.01 gpw (~1.13 total) for a virtual novice.
A caveat to my yield report: i used a scrog. I have the feeling that using a SOG or scrog methodology may be necessary in order to optimize one's yield to the point that 1 gpw is relatively straightforward to attain.

You just can't compare grows.
I like the mpg analogy.
One driver is trying to get to the destination as fast as possible. The next is trying to get there with using the least amount of fuel/least amount of cost. The next is trying to get there with their car in the best possible condition. The next has cars arriving at the destination quite often and wants to maximize their delivery times. Then you have the factor of what cars and engines are being used by each person. What octane fuel they are each using. What type of tires are being used. How aerodynamic are the bodies of the cars being used. What roads/routes are being taken by each driver.
So yeah gpw isn't something to go by. At times it can be used but mostly just to tell someone they aren't doing shit right and that they should be getting more yeild.

Exactly! Shit, if I throw 49 newly rooted cuts with a 6 day veg time into a 4x4 tray and flower for 64 days, for a total of 70 days, I could crush a gpw. That is the only factor I use for a gpw, is total grow time, anything else is really irrelevant. If someone veg 1 plant for 4 months and flowers for 10 weeks and gets 2.2lb from 1000w flowering bulb and used 1000w for the veg (because that would be a huge freaking plant and would totally need it most of the time).. That is not 1gpw imo. Thats a waste of electric, but some people want to lower their plant count. And in place they end up paying damn near the cost of electric as they would get in yield, pretty pointless on a medium /large scale since every 1000w running 12hrs a day in cali costs about 150-200$a month.
Imo, gpw is only useful if all parameters of each grow is the same. I could grow some stupid bunk strain that yield 3gpw, but no one wants doo doo buds. If a dank strain yields good, which is rare, thats another story.
For example, I have 38 plants vegged for about 7 days that I put into flower. Basically I used no electric for veg (200w for the whole veg time) and then put them into flower under 1000w hps. I HOPE they get 2.2lb. But who knows. I haven't grown the strains before and I'm also in rockwool which I've never grown in, but if they were a strain I were familiar with and a medium I were familiar with, 70 days total to get x amount of pounds would give me an idea if I had grown better than the previous grow if the conditions were the same.
What I mean is, it's basically a personal calculation to see if you've bettered yourself, it works for any style of growing, 1 plant per light or a 100 per light , all the parameters have to be the same for it to mean anything, including, veg time, strain, nutes, lighting, flower time, and plant count. Otherwise it's useless info for comparison. If you grow plants under 1000w that you vegged for 30 days and get 1gpw, but you also grew 36 plants with no veg time and got 1gpw, well the faster grow is much better obviously because you saved 4 weeks of time, nutes and electric.

14 day veg, 12 plants ( new strains to me) - should be 1-1.5lb, maybe 2..most likely not 2 though.
7 day veg, 38 plants (28 plants are a strain I grew 1 plant of before, the other 10 are new) - should be 2lb+
Totally different grow methods, medium, strains, time. So gpw here means nothing at all except maybe a reason I should grow my plants a certain way because it yields more in a shorter period of time. But when you grow sea of green, it's a risk because of plant count. So it's really up to the grower to decide what they want to do. Sea of green will always yield the most in the shortest period of time for the cheapest cost, hands down, no way around it, period. You can not argue this unless you don't know what you're talking about.

Some folks do legal grows.
Some of those folks live in places where plant count is limited, such as DC where folks are limited to 3 or 6 flowering plants depending on whether there is more than one adult in the residence.
So in order to optimize yield it's best to veg long and scrog 'em big.

If someone is growing strictly for themselves they may not want a large yield, they may want to grow several different varieties in relatively small quantities, to stay within possession limits and keep it on the legal tip, for one reason. Additionally, some lucky fucks have a very low cost per kw so they don't give a shit how much electricity costs, they will barely notice unless they are running more than ten thousand watts or something. All which goes to support the main point that @Anon Emaus and @AlphaPhase made; It can help you learn about your own grow, and teaches you very little in comparison with other grows/growers. (unless you run it like a science experiment among a group of growers with another group as a control, good luck with that) Let's face it, most of us are a bunch of untrained stoners making guesses, past a certain point. The best among us do research and develop skills. And the very best don't let it go to their heads.

Yeah, I touched base on why someone would grow a single large plant per light, it's just not really economical in California because our electric rates are .36cents a kwh, so to veg for 90 days and flower for 70 days, you're looking at 1200$ plus in electric for one plant. If I had to do this I wouldn't even grow indoor, I'd just use the wonderful sun and not worry about yield because it would be a hell of a lot more in the end then a year of indoor growing would accomplish if growing single plants indoor, and it would be mostly free
in California most people try to figure out a way to optimize yield by using the least amount of electric as to be energy conscious, they have us by the balls. Luckily in my County, there is no plant count, the rules go by square footage.
hate to say it but you have no idea what you talking about. veg isnt the issue gpw should only be counted on flower cycle veg time is the kicker that shouldnt be calculated. using more plants to cut down on veg is better than vegging for 3 week or a month or 2 months thats just retarded unless you are playing the number game.
what you do is you fill up a canopy in a certain sqft area lets say 4x4 and put it under 1k light make it 16 plants and 2-3 day veg time and flip to flower. now you have a 4x4 area that will produce 2lbs. area is what really matters in yield. light just has to be a certain lumen weather you use 600 1000k or leds or whatever. a 1k hps should cover aprox 4X5 area if you use a certain hood and check with light meter. in that 4x4 doesnt matter 1 plant 4 plants 9 plants or 16 it will yield what ever can fit in a 4x4 but most people waste time on vegging instead of going more plant numbers. its all about canopy effieciency and light effieciency. then everything else is strain and dialing it in.
if you veg for 6 months and train that shit you better put that shit under at least 4k and cover a 64sqft area or more and will still yield what a 8x8 area would yeild which if done right should be 7-9 lbs if you only used 1k light you are gonna get shit buds except where the light is the best which is the most retarded setup
this is just an example cause i have no way of know what a 6 month veg on one plant will become in size and height cause i wouldnt waste that much time and electricity

Can also be done with 600 clones under a 600 hps guaranteed gram per watt lol,
Never got a gram per watt of bud good quality bud ,I do get a lb per plant of good dense buds,round about 28g of good quality hash and around 12 gram of bho that I use for e cig liquids,I can pretty much say that what my room will throw me every grow ,I think a room can be maxed out give or take a oz.But not 1200gram from the 2 plants,dry cured bud ,896 gram,give or take a oz

Like many have said... GPW is a fairly meaningless figure in reality. It can help an individual measure his own progress over time, but cannot really be used to compare to others' grows because it only considers flower wattage. A much better gauge of a grow's efficiency is Grams per Kilowatt Hour because this can account for veg time/light size too.
Yield should be calculated against the total kilowatt hours used throughout the whole grow cycle for a much more interesting measurement. For example;
Veg
50W x 18hrs = 0.9KWh per day
0.9KWh x 30days = 27KWh Veg
Flower LED
100W x 11hrs = 1.1KWh per day
1.1KWh x 70days = 77KWh
Flower HPS
150W x 11hrs = 1.65KWh per day
1.65KWh x 30days = 49.5KWh
Total
Total Power Use = 153.5KWh
Total Yield = 140g
140g/153.5KWh = 0.91g/KWh
*In this example I actually added 150W HPS halfway through flowering to give the plants a boost, so that is why the HPS only ran for 30 days in flower*

What concerns me is not grams per watt but maximum yield i can pull from a 3x3 area. Ive done the led, hps, cfl, mh. The best performance came from mh/hps hands down. The cfl came in second while the led came in dead last. Im sure other people will get different results but i am speaking from my experience which is limited to my own strains, types of lights, grow room, nutes, medium, basically the way i like to grow. I probably could have changed one thing and had a different outcome but im sticking to my own experiment and what works for me.
yes this Its really more of how much can you get from a certain area and just hanging lights to cover said area with enough lumen. everything else is how dense your canopy is and strain and if you have any other problems
