alright heres the? who on here really gets 1grm per watt... if so please share what strain ,system used, how long veged, nutes, how long flower lights so fourth ......cuz ive benn doin it for a while and i just cant find the right combination oh ya indoor growers only....we know about outdoors...even if you dont get a gram per watt share what you get and how you achieve it...just trying to further my knowledge
...1 gram per watt...

g/w really should never be taken into consideration as it does not compare the total energy used during the grow but just the energy used at one point in time. I don't feel like typing out something particular for this thread so here is a comparison I posted on another thread:
"I yielded just over .4g/w I am going to argue g/w though. What people should take into consideration is grams per kilowatt hour (kWh). grams/kWh reflects the total amount of energy used compared to yield versus just the amount of watts run at a time compared to yield.
If you vegged for 6 months under a 1kW and then yielded 1000 grams that would be 1 g/w. This would be (30(days/month) x 6(months) x 18(hrs/day on)x 1kWh) for veg + 8(weeks) x 7(days a week) x 12(hrs a day) x 1kWh for flower = 3912 kWh
So you would have managed to get ~.25g/kWh
A three month veg that yielded 1000g would be .43g/kWh
A two month veg yielding 1000g would be .57g/kWh
A one month veg yielding 1000g would be .83g/kWh - I hear this is what you want to aim for but need to run high numbers to achieve this.
My first CFL grow I managed 151.6g from 6 small plants in 2.5months (2 week veg 8 week flower) using 290 kWh (120w veg for 2 weeks + 388w flower for 8 weeks. That is .52g/kWh"

Yes I am correct.
You want to know where you fit in? Calculate your grams per kilowatt hour the following way:
Multiply this and save the number:
(weeks of veg) x (watts used durring veg) x (hours per day your lights were on) x 7. Now divide this number by 1000
Now multiply this and save the number:
(weeks of flower) x (watts used durring flower) x (hours per day your lights were on) x 7. Now divide this number by 1000
Add both the top number and the bottom number. This is the total Kilowatt hours you used - these are what they charge you by on your electric bill.
Divide your yield in grams by that number. If it is higher than .5 you are doing well. If it is higher than .8 you are doing REALLY well (this is equivalent to a respectable 1g/1w grow when considering a good time frame)
How to achieve this? Put 16 plants in 1-3 gallon containers into a 4x4 tent. Veg under a 400 then 600w MH for 4 weeks at 18hrs on. Flip to 12/12 under the 600w for 2 weeks and finish the last 6-8 weeks with a 1000w HPS. Should yield ~ 2oz per plant in 12 weeks. That is 855 kWhs and 896 grams - a true g/w and g/kWh.

that's because the whole grams per watt theory is pure shit man
if anyone actually followed it, no one would ever get a single gram per watt.
take for example, your ventilation...pretty sure your using watts there too.
and your motions and hauling of stuff around also would calculate into it.
good luck if you ever expect to have an accurate answer.
EDIT:
before anyone jumps all over me with the wrath, a question...
you use nutes, yeah? well, you do know it took energy to create it and transport it to your plants, but do you know the the watts?
either you calculate the TOTAL energy for the WHOLE grow or your end result is botched....and wrong.

This is totally true. And a 1000w light really pulls ~1200w...
What you should do it keep track of ALL expenses in a program like quickbooks and then document all yields and profits from yields. kWhs is shown on your electricity bill, screw adding up the gear yourself as it will ALWAYS be wrong - 23w CFLs pull about 18w and 600w ballasts pull ~700. Fuck g/w or g/kWh and focus on $/g.
i dont think you could pull 2oz a plant in a 4/4 tent with 16 plants...thats way to many plants ....example you need an average plant 2... to 3 feet for 2oz if not trained and it would be a rain forest in there bottoms would amount ta crap no light penetration at all at that point and why wouldnt u just use the 1000 watter from the get in flower ta keep them short and stacked .... in your theory ta vegg any longer than 2 weeks would not fit 16 plants let alone the stretch ...would kill u alone

These are 1 oz a piece in 1 gal pots with 2 week veg done under CFLs. Could easily fit many more than 16 of these in a 4x4 (32 if need be) - i had 8 in a 3'wx2'dx4'h closet.
Here are 50 in a 4x8 in 5 gal pots:
But if it makes you happier you could do in a 4x6 space in a an open room on a light mover. Might yield a bit more this way.

My Interpretation of grams per watt is the following:
If I have a 1000 watt light for flowering and I'm doing everything right, I should yield 1000 grams for a flowering cycle. Its just meant to be a simple goal to try and reach.
Personally I average appx 0.7 grams per watt. I have a perpetual grow so I just track yield for a 2 month period and use that for my calculation.
How I do this:
I clone from mothers in a bubbler and mostly run DWC. My extra clones go in soil and I stick them in any open space around the DWC tubs
I typically veg my clones in dwc under florescents for 2 - 3 weeks and usually top once.
Nutes:
In DWC, I use Advanced Sensi Grow and Bloom A + B. For veg I go 600 ppm and in flower 1000 ppm (75% Bloom and 25% Grow nutes) I think a little extra nitrogen keeps your plant healthy and vigorous especially early in flower. I change my tubs every 2 weeks. In between changes at the 7 day mark I add a light does top off usually 500 ppm. In addition I add CalMag because I use RO water and Big Bud from week 2 till week 6 of flower. On my last tub change before Harvest I've started running General Hydoponics Florablend (Organic) at 500 ppm.
In Soil I use a mixture of Blood Meal and Bone Meal in my soil for veg and before I go to flower I transplant to a bigger pot and add a a little extra bone meal to the soil. I water every other watering in flower with General Hydoponics Florablend (Organic) at 5 to 10 ml per gallon of water.
Strains:
Mainly LA Woman, Strawberry Cough, White Rhino and Blueberry Skunk. I just started Tangerine Dream, Sage and Sour, Himalayan Gold and Space from Seed.
Things I think I can do better to Increase yield:
1). Veg under a MH light.
2). Change my tubs every week instead of every 2 weeks.

you can achieve alot in any space indeed 32 plants in a 4/4 tent..a little too much.. all im sayin people have plant limits and 32 is alot in certain areas 16 a little bigger will produce about the same 8 twice as big will produce as much as 16..... co2 and every other things adds

Hey just saw that you say you grow LA Woman, This is the strain that i achieved almost a g/w total was 220gs dry under a 250w hps, only got pics of my 94g dry main cola tho i got another 4 - 5 oz off the rest of her. Just thought i'd say since he was after a high yielder from the sounds of it. If only i had my 400w and grow tent when i did her god only knows what she could of yielded with that. If you want high yeilds grow DWC trust me. Nice1

the theory of grams per watt should not calculate the amount of energy spent on the whole grow operation. the first answer was way over complicated - that is a grow efficiency equation. Trophy1 one stated it best. the whole gram per watt thing is rough estimate of what you should havest in a 2 month flower period, no matter the other details. you tweak those details to meet your needs and goals.

ok my last grow Afganistan kush 2270 grams Dry ( 5 pounds )
power 2500 average watts 2 1/2 1000 watt lights bulb hordilux super blue MH / HPS all in one bulb
products used veg for 5 weeks advanced nutrients- A and B humux, Greens , Magic cal. superthrive 42" tall plants in veg
Flowered 62 days final height 52 - 56 "
products used optimum A-B super B max , Grozyome, Fulvix, Carbo boost , jurrasic bloom
how i came to this gram and light thing is could only trim so much and it worked out being a area of 2 1/2 light
of course they were seperate screens per trim day

My last grow I had [1 snow white] under a [250 watt hps]. I vegged for 8 weeks, topped [bens 4 colas] and loaded it with nutes, and I still only managed 110 grams dry with that 250 watt. I now have a 600 watt 95,000 lumen secret jardin, hopefully I can up that. But yea, 1 gram per watt is tough, no way I could have ever done that with a 250watt hps. especially with the limited spectrum. Now I have this
