lets talk yield, .5g to 2.5 grams per watt. how can we get there?

That's methane from the biodigestor being burned to produce steam for electrical generation. The CO2 by product would also no doubt be recycled back into the greenhouse for sure!

Great stuff!
Cool isnt it? Talk about efficiency. Top quality produce with next to no impact on environment and very low cost. Labor in those big commercial setups has largely been automated also. Next all we need as a planet is affordable highly efficient desalination plants for clean water. I heard at the moment they are expensive and intensive. Maintenance is high also. The Saudis got em i believe.

One could also use certain kinds of plants to drink brackish water and transpire pure water vapor in an enclosed space like a greenhouse, then condense that back into liquid.

Anyone can get those numbers as long as you don't fuck up in veg and leave them in there for a month or two longer than you intend. Also a heavy yeild helps

What numbers? The thread title? No....sorry. I dont think so. Theres only so much one can do with hps lamps indoors. The numbers yall place on here is just silly. I been in this game a long ass time and seen and grown a hell of alot. This 2 ....2.5...or 3 grams per watt shit is total forum bullshit. And perpetuated by realtively newish growers that dont know they asshole from an elbow.

Idk I've seen plenty of guys on here who veg a extra month and have hit 2.5. They have perfected their shit but it's been achieved before

I dont care if your jack and the beanstalk himself. Theres not a grower out there gonna pull 5 or 6 pounds per thousand watt. Say what you want....anythings possible...yeah rite.

I hate these threads lol. Makes me feel very inadequate lol. I get around one per and that's on a good day not average :(. I am getting better though lol. And this gram per watt thing is just ridiculous, how in the hell could it be used as a comparison without time factored in?

I got 20 plants in this stadium grow , with 2 600s vegging in coco,AN nutes,will dim up 2 750 (bare bulb). Co2 evey 3 hours ppm 900-1200 climate on point ,sealed room,going to flip very soon as soon as I add a U screen id feel very very lucky to 1.5 lbs per bulb and that's less then 1 gpw. 8 blue dream 8 grape invaders 4 gg4 finger crossed I'll report soon (well if I remeber in 2.5-3 mths or someone tags me haha)

With a 3 week veg I pull down every 49-56 days getting 1.12- 1.34 gpw, can flip a room 6-7 times a year that way while vegging separately.
I usually veg separately too, especially in the summer. In the winter I veg in the tents I have to create more heat...Don't know what strains you got going only 7 or 8 weeks??

Most I ever got was about 1.15 grams per watt, but I have height restrictions bc of 6 foot tent. I really don't see anything over 1.75 grams per watt realistic.... And that's with an awesome strain.

Anything over 1per watt Is way above average. I only rarely see people getting into to 2 range. No one should ever fell bad about 1 per

Anyone getting 1.5 or 2 pounds a 1000 watter...consider yerself a great fukin grower man. Bottom line end of story. I speak the truth too. Hell....even you 20 ounce a lamp growers...pat yerself on the back. Ibeen growing dope in some fashion inside for decades man. And one thing is for sure.....to do it rite is expensive as hell and one little fuk up will set you back. Its a passion bros..and dammit....most of you are cranking out good ass weed. At the end of the day....thats all that matters. Grow on my homies....grow on.

You dont see anyone getting 2 grams per watt.....ever. That is a fact. Anyone approaching 0.7 or 0.8 is the shit in my book. Even 0.6 growers....you gotta be paying attention to some fukin thing. Anything over a pound per 1000 watt hps...youre an above averagw grower....no doubt. Again....i speak the truth. Not many can appreciate how difficult it is to get a gram per watt of flowering light at harvest time. People that throw the numbers around casually are full of shit and do not grasp the concept. It actually is a fairly decent measure. Any other variable can be changed. The only constants are watts....and time.

I agree, a feel good number that most obtain with months of vegatation.

The formula i was taught was grams x watts divided by the number of months spent flowering. ( 45 days equals 1.5 months)

I use ounces per sq ft.

Extending your pre flower stretch and flowering time by going outside the 12/12 schedule is something to explore.

Breeders have been shortening finishing times for decades now, so that's incorrect.

Watts are uniquely dependent on the device they're fed into and more efficient led setups are appearing all the time. @REALSTYLES built a 70% efficient COB LED light and was close to 2gpw. Others have mentioned they're knocking on the same door, again with COB LED. So that assertion is even further from the facts on the ground.

I absolutely think 2gpw is possible and with the new techniques and technologies I've seen recently, I'd say it's even likely to become an expected standard in the not too distant future.

As ever, you say some very intriguing things. I have a batch coming that's going to be too small to fill in the trellis. What do you suggest to extend the stretch phase and help me fill things in?

You know me tty...iam in the hps camp...still. This whole new lighting (cob) is a different ball game. And your at that frontier. You and a small handful of others are the Lewis and Clark with the new cob stuff. And its about time i say. Only so much you can do with HID lighting. Its old news. Double ended is about as good as it will get with gas pressure lamps.

14/10 to 12/12 over a 2-3 week span is the method.

A two tier system where one fills the bottom half predominately. if your containers are not bound to the floor, raising the other one behind it a couple feet also might be a fix.
