Definitely not.
Depends on if you are skilled enough to use CO2 effectively.
For a nOOb, you will more likely hit about 0.3 g/watt/month if you are lucky.
Am I having deja vu or did you post this Q in another thread?
1Gram/Watt-Wet lol.
Even if you had the perfect environment, with a perfect feeding schedule/portion, etc... it would still be at least a bit dependent on the strain. As most people here know, sativa strains will likely not yield as much as a heavy indica yielder. Thus, I don't think you can get 1g/watt no matter what in some cases. I wouldn't be too worried about that, though. Plus, if you had, say, 5000 watts running in your grow room... do you actually think you'd be able to yield 5000 grams wet unless you had plenty of plants? Correct me if I'm wrong, though...
You can get 0.5g/watt/per month in flower room; thus, on an 8-week strain, you can get 1g/watt/cycle.
5-1000W HPS creating 11.5 Lbs of wet product, Then dry thats about 3-4Lbs. Yeah I think thats possible. I've never done anything close to that scale but my 246W CFL's created atleast 10 O's of wet down to about 2.5 O's Dry
I yielded 114 Oz bone dry weight 44.5 plants under 5 * 600W HPS with no CO2, just Advanced Nutrients products during the first week of February 2007. Temperature was not an Issue because it was the middle of winter. Half the room was G-13, just under half was Chronic with 4 Sensi Star. I have pics. The room has/had never been so rammed with plants. The G15 were over 5' tall in their pots. The Chronic and Stars ranged between 18 and 24 inches.
It is possible to exceed 1gram per watt:
114 ounce = 3 231.845 636 25 gram
5 * 600 = 3000W
Difference 231.85g or 108% efficient in terms of 1g per W
i dont think its the wattage so much as things like if your in hydro, what kind of light, plant, nuts, etc.
hydro means more energy to plants for bud, so itd get more per watt
Umm- the metric's meaningless if it's not expressed as g/w/m
To illustrate - if a car is going 100 miles an hour, it's barrelling down the highway.
If the same car is going 100 miles a month- yer pushing it.
>1 g/w/m is not as hard as it sounds- ya just gotta be efficient ( and aware of diminishing returns in lighting investment per sq foot)
well im kinda getting mixed messages here fellas is it possible the strain says 350g - 1000g does that mean as long as your not a total idiot the least you will yield is 350g a sq meter
No, it means that is the yield that an efficient and experienced grower can yield in a SOG setup.
1000g per square meter is a bit of a fantasy though, lol! You'd have to be running CO2 dialed in TIGHT to even consider that a possibility.
Just FYI... only n00bs ask the 'how much am I gonna get off this plant' question... :D
Stinky - Rhizome ,
When you guys are figuring G.P.W you use the no. of months as a divisor ?
I've never seen it done before , When Latewood figured yields in his "All You Need 3 part" thread he didn't / by no. of mos. ?
I get 1362 g. from 2000 watts = .681 G.P.W :)
I figure it out your way It's almost disheartening .
1362 g. from 2000 watts = .681 / 4 mos. = .17 G.PW :(

Crispi, you're putting on a quite a bit of WOOD by growing large trees (but they are SO beautiful!!!!).
The 'month' part is just as important as the g or w.
Maximum efficiency is from rooted clones in SOG. In that setup, the BULK of the energy that the little plant puts into its short life is in bud production... I'd actually like to see some of your numbers for g/w/m TOTAL DRY PLANT WEIGHT, buds, roots, stalks, leaves, and all, not simply dry buds... you'll see where your electricity is going.
Good point Stinky .
"Wood" isn't an exag. either, 1.5 inches in diameter w/ bark like a tree last grow.
When this grows done and chopped down and hanging I'll hang 1 from a fishing scale just for kicks . :D
Peace Sis .

i think i remember at OG, that BOG(my hero) got a lb off one 400w hps in soil. but we all know he wasnt your average grower.i wish i could get my hands on any of his strains.
XC- metric doesn't apply cleanly to your room- you veg in the same space, right?
1g/w/m is the standard for flower room time only- designed to allow comparisons between multi-room grows. Formula doesn't include veg time- assumes that plants of whatever size are moved into flower and immediately or almost immediately flipped.
If you take off all that veg time, your #'s look better.
Also, you're in an artificial situation that reduces plant #'s- if you'd done , say , 30, veged the same amount of time, and then flowered, your weight yeild would have been a LOT higher. ( Your room would also have been crazy crowded)
Recap- 1g/w/m standard doesn't apply to the style of grow that you're involved in- You have VERY GOOD REASONS to do it the way you do, but your style isn't appropriate for a commercial production room.
