1 Gram Per Watt

experience

 

[djingo]

a healthy, well developed rootsystem. nice sog with a top clone. bucket volume should be atleast 6,5L / 2 gallon (except aerophonics).
example: my ak47 cut steady produces 40-45g dry bud each plant when veg for 4 weeks.
I put 15-18 plants under 600w. very important is that all clones are of high quality.

 

[Hydro-Soil]

Color me weird but I don't count 1gpw from a setup that requires a veg time of longer than a week.

With that restriction you're looking at strain and plant numbers.... once you have a near perfect enviro set up.

Stay Safe!

 

[Scrappy-doo]

One word. SCROG.

Lighting does not matter very much. My current grow is using a bad boy t5 light and I am certain I will be getting at least 1gpw.

Do a vertical scrog and you can turn that 1 into a 2.

 

[VerdantGreen]

grow your plants around your light, rather than underneath it. it's called vertical.
then you'll be coming on here asking "how do I get 2 gpw?"

i think that people over hype-vertical yields. i get well over 1gpw consistently in a horizontal setup and i see the vert guys giving it the large one about their yields - but the actual numbers rarely live up to their hype.

case in point - the vert grow in your sig yielded 0.5 gpw - have your yields more than doubled since then ??

not trying to be a dick, but i think a well done horizontal grow can match up to a well done vert grow yield-wise.

The size of the area lighted by the bulb is to take into consideration, also. A 400 W in a .6 sqm won't never give 400 gr. I noticed that i used to get more without using a tent (open growing area) than inside a "not big" tent. But for odor control the tent is better.

I don't know if it's over hyped Verdant, but I think I get what you are saying all the same

The essential thing to remember with vertical growing is the space that is achieved... For instance, lighting a given area with with 1 x 600w bulb horizontally results in a 3'x3' or max 4'x4' grow space. Vertically you quadruple that.... So lets say for instance you have a 4x4' tent, hung horizontally you can fit squeeze 34 3.5L square pots on the floor.

You can hang the lamp vertically and fit nearly 100 3.5L square pots in that space huddled around the single 600. Now I understand this is all SOG stylee, but I'm sure you will see how this would apply to any style of growing... 4 x 3' space vs 1 x 3' space....

humm...

to be On Point..

One will never achieve Gram Per Watt.. if they never achieve a sort
of language with their plants. Being able to read your plants and in a way communicate
with them is how one will gain the knowledge to grow 1 GPW.

Granted I believe the COMMON Gram Per Watt.. is in reference
to the LIGHTING WATTAGE used only..

I personally believe that ALL wattage should be added up and THOSE #s used.

I agree. Alot of things have to be in line before one can take advantage of teh vertical bulb imo. I often hear people refer to the increased canopy area of a vertical bulb, however, this also means the light is not as concentrated. In the vert forum, there is not many grows that i have seen that blow away your typical horizontal sog/scrog.

Space is also an issue. In a 4x8 tent with 2K, one can scrog/sog close to 1gm/watt with a decent strain, relatively easy imo. Hydro makes it even easier.

all good points , but there are things that mitigate the extra space - like buds having more of a blocking action to the light when coming from the side, buds taking more space in a vertical canopy than they do in horizontal. canopy area becoming smaller as the buds grow in. also reflected light is dispersed rather than being from a point source - which is very useful to the plant.

vertical is a totally valid way to grow, and some people do it very well
if going vert doubles your yields then thats great... but it also means that your weren't doing horizontal as well as you could.

I dont think ive ever got under a gpw in Scrog growing, average 1.1-1.2gpw. master scrog & you'll hit that with any wattage lighting(HPS/CMH etc), apart from CFL & the like.

 

[roach]

i grow organic in soil under 600w HPS, and i very rarely get under 1 gram pr watt no matter what strain, so in hydro with one of the "commercial" hybrids you should always get above that or your doing something wrong

Hi Verdant

I highlighted SOG in my examples for just the reasons you point out above; buds blocking other plants. I feel SOG limits this issue to slight annoyance at worst

Here's a very good pic that explains my point well:

I also think it would be easier and quicker, which we really must keep in mind considering vegging = watts used skewing the gpw numbers, to achieve 1gpw running a SOG vertically (because of added space) than it would be from a flat horizontal based scrog.

That's not taking anything away from scrogging, I have mainly grown SOG but as you may have noticed from the K+ I have been trawling through your thread for tips on scrogging as I know you are well accomplished with it. It is just easier, quicker and essentially more efficient to buy 100 clones stick em round 600w light and wait for them to yield 12g each not a heard feat in anybodies book imo then wait for your 2gpw Buying clones removes the need to have a separate veg area btw, saying that I can root 100+ clones under 4 x 18w T8's no probs...

Ditto on that my brother.

Either way you look at it your either one...
wasting some light area... (Hor)
or
Wasting some Sq Footage FLOOR area... (Ver)

I use only 600 watt HIDs because in my experience and mind... the primary range of light from a 600 watter is 10inch - 30inches
from the bulb/hood.

When I grow, I do a type of SOG/SCROG hybrid.

Never let the plant reach OUTSIDE the primary range of light.

assuring that the ENTIRE plant will turn into a solid Nug limiting
the amount of EMPTY Stem Zone on the plant.

also doing this pretty much makes Veg time less then 1 week.


(Me personally... when comparing GPW.. you HAVE TO account for every watt... including veg time.. unless you dont veg and only buy them)

Im sure many people's rates will drop a lot if they add in there fans... pumps... and all the happy jiv.

 

[Snagglepuss]

"So if im doing my math right" ,for a gram per watt....I should get 1000 grams off of a 1000watts....thats like 2 lbs.....who gets 2 lbs a light?

 

[drifter1978]

ok guys and gals,i have a legal matter going at the moment and i was growing under 2 X 400 watt lights and the cops are saying after doing a yeild examination only by the photos of the scene that i would get 62 Os from 31 plants which works out to be 2 grams a watt,i know this to be untrue and you probably know this as well,
how can i prove this to be untrue ,cause they are going to beleive a cop before me or as they say mr asia.

PEACE

 

[roll it large]

Drifter when did you get busted and are you in the uk?

My first grow was 4000 watts. I yeilded 6 ounces. Robbery will do this if u want a gpw don't have friends they get jealous and feel left out. My second grow i yielded 74 ounces with two lights, over gpw. I was so paranoid I never leftthe location in fear of robbery. Which in turn gave me more time to care for the plants I was i. The garden four hours a day min. I used cap ebb and grow with co2. Fox farm nutes. I had root rot real bad. I also killed a plant ob day 42 because of hermies (and inexpierience) the plant weighed 64 grams (not counted in the 74 gram figure)

 

[John LOQUE]

i never get 1 gpw and i wonder how it is possible except growing trees in a vertical grow, and it means a long time in veg using space and light. I usually veg from seeds 3 weeks before 12/12. Since i grow in tents, the yield has decreased maybe because i over crowed. I used 400 w in a .64 or 1.0 square meter tent and i never get 400 gr.

To get 1 gpw, grow clones with 250 W by square meter, in dwc, with optimum temps days and nights, and yes it's possible to get 250 gr. Breeders say up to 600 gr by sq meter, in a real sq meter, 1 by 1 ? I would love to do it ...

The main question, and it has been said here, is how many grams per kilowatthour. Weight vs energy spent.

 

[TLoft13]

I still think Jorge Cervantez got it right: Only gram per watt per month makes sense, with 0,5 gpw as "the benchmark". You can always have new clones ready in any size you like, considering the average flower cycle gives you a two month window. And the space and electricity requirements of your dedicated veg area will be quite small/insignificant compared to the flower room.
Everything else are special requirements were efficiency is not the top priority, like maximum yield out of metric volume, plant count restrictions, or using fluoros/LEDs because of very high heat or for extra stealth.
