the info on this 21h36/12h states it's best tried when your plants are at full flowering, about the last two weeks before harvesting.
What is Your AVERAGE yeild per watt?!?!?!?

I have never really crunched the numbers but my 2400 watt setup gets me a minimum of 4.5lbs from 3 plants.For instance I dont think I have ever seen a single indoor plant with more than, 1 pound(dry weight) on it using a single 1000watt HPS. ( if someone has, please post the link or some pictures)
thanks for your input,
also if you post up some amazing number, (i.e. 3 grams per watt) please post some pictures, so I can believe you.
lol
This was the last grow:
And this is the current grow pics taken today:
Oh and there was also the 3lbs Jack Herer trees:

nice dude ! , i crunched for you .84 grams per watt .... thats funny cuz its exactly what i came up with for mine as well

M blaze, thank you for posting such beautiful pics man, what a great thing to wake up 2!
man im drooling haha
So how long was veg time on this about?
Now for this to be a truly informative thread, please include veg times, strains,flowering times etc.. thanks my friends = )
for instance if someone gets 3 lbs off of 2400 watts, but veg's 2 months, then flowers 2 months. Total time has to be taken into account, to figure out how efficient a set up is.
someone using 2400 watts using 50 plants put them to flowering ASAP skipping veg time totally, if was able to pull 2 pounds every 65 days, that would be a bit more efficient.
I dont think the number of plants is as in the equation, unless it directly relates to how long you have to veg for.
lets say it takes 65 days to make one pound of buds using one single thousand watt light, it wouldn't matter if you used 2 plants, or 200, if the yields are the same.
thanks again for da bomb pics blaze, im going to go check out your thread right now,
peace in

theres no way to make reliable comparisons if you want to think about the additional factors such as the length of flowering time.
the real way to figure this out would be ( wattage x hours per day x number of days) and then divide your yield by that would give you the EXACT figure for how many grams per watt ... and its gonna be something like 0.000004 grams per watt
a more proper way should be grams per KWH based on the following:
400w x 12 hours per day x 70 days flowering = 336,000 watts / 1000 = 336KWH . figuring a total yield of 12 ounces is .035 grams per KWH .... scary right ? but going by the way everyone does (not really reality) this is .84 grams per watt

i reckon it should be asstandard 9 weeks unless were talkin sativas?1!? idk im a mess right now

that sounds like the proper equation, im kinda lost though sorry weedman. thanks for the help man
ok so say your using 2000 watts, and harvested 2.5 lbs(dry weight) in 65 days.
so 2000w x 12 hours per day x 65 days flowering =1560 kwh used,now what.. 2.5 lbs is 1120 grams
how do I complete the equation.
divide 1120/1560???
giving me .7 grams per watt????

i don't see how length of flowering time makes a difference, does that mean that someone who grows indica's is far more efficient for their grow space than someone growing sativa's, it would make it even harder to compare then,
its done like it is so people can gauge how efficient their grow is for their space
my current flowering area i am short of females so i'm unsure what my gpw will be, but normally i get 1.33gpw with my best being as high as 2gpw

as high as 2 grams per watt?
flowering times does make a difference, someone who grows an indica that is a heavy producer, that takes 9 weeks to flower, is def more efficient that a med producing sativa that takes 12 weeks...
some people grow for themselves to have a personal stash, some people grow to sell it.
if your growing to make money, how efficient a set up is sorta important.

well no because in that instance your calculating loss against profit, not comparing your grow space against others to see how efficient your grow is, because then you would have to take into account sale cost as well, its kept as simple as it is for a reason, because you can't just add lil bits in as you choose, because for efficiency on weight and time you would want the cheapest fastest flowering strain which might not go for as much per gram as a better longer flowering strain,as high as 2 grams per watt?

the whole gpw thing came around because growers always remember their best harvest and would say shit like oh back in the summer of 98 i got 15 pounds or whatever, but that doesn't take into account how efficient that grow was, it could have been from 300 plants, where someone else could have grown 150 plants and got a similar amount, rating it as gpw based on yield vs power useage gives people a gauge of where there at and where they can improve, but for someone comparing his sativa grow against an indica grow the sativa may outyield the indica and be utilizing his setup and area better, but taking an extra couple of weeks to produce a better finished product

agreed... the gram per watt thing is just a basic way to judge how efficiently or unefficiently you are growing... its just a bench mark.. its to hard to compare person to person and get a real comparison because different people grow for different reasons and strains all yield differently.. and even the same strain yields differently amongst growers from setup to setup... someone who wants to sell their harvest will look for and in everyway strive to get their crop yield up, and are prolly concerned less with over all quality.. not saying they dont care.. but that yield is most important in the end... where as a patient or someone just growing their own personals, while wanting a good yielding harvest, is more concerned with quality... so its safe to say that the personal grower will likely have less of a gram per watt yield than the seller... in the end it doesnt matter as long as your happy with your results.. anyone who wants to increase yield can find a multitude of ways to do it to increase their gr/w ratio.. but it really just depends on the person and what they want out of their plants...

if the person finishes theirs quicker and same or higher yield then .... YES
how could the length of flowering time NOT make a difference ?
the question is grams per watt ............the more days ... the more wattage

2000w x 12 hours per day x 65 days flowering =1560 kwh used,now what.. 2.5 lbs is 1120 grams
divide 1120 by 1560 giving me .7 grams per watt.
so that .7 is that the correct way (scary way) or the way everyone else does it(not really reality)?

how does that establish the ability of the grower, its no reference to anything other than how quickly your strain grewif the person finishes theirs quicker and same or higher yield then .... YES

i guess the guy who used some crappy bag seed that came from an awful indica is the overall winner because he didn't pay for his seeds or cuttings but still finished in 6 weeks got 5 shitty weed which was badly grown and lacks potency but because the guy who got 9 ounces but took 13 weeks to get a quality grow with nice full buds that are full of potency and grown well bought his seeds too,
i guess if you wanna be as cheap as possible then your scale is ok, it finds out who is growing the most commercial crap on the site
nice system, way to go

thats cool if you wanna find out how much it costs you, but it in no way rates you as a grower, just how much it cost you over a set period to grow whatever type of weed, but good luck on being in touch with the real world, cus the real world goes by grams per watt the real world way (power rating of the lamp you used)
