Almost 3 pounds from a 1000 water in a 5x5 tent? And from those pics? Looks more like 1.5 to me.

Not my garden, but it's the only closest thing I could find through searching forums and google. Here's the album if you wanna see. It's hard to find pictures of a similar garden because the grow forums aren't really indexed on google and the search bar only accepts exact words/phrases.

He got 36 full mason jars of bud, but alas again no fuckin weigh ins on a scale lol

It's definitely 2.66 pounds though. And it's pretty decent stuff.

Lots o stuff went to the trim pile it looks like

That's not 2.77 pounds bro. Trust me. Just that details alone without pic makes me very skeptical. 2.77 with a single thouie in a tent? Nada. Not my pounds and they way I trim dry and cure anyways. And any other grower I know.

Do you know if he used co2?

skoomd · Apr 5, 2018

The buds in those jars and the buds inside that tent match up identically. Meaning whatever was in that tent somehow fit into 36x 1 quart jars. And it's good stuff too. Not fluff.

I mean if it was 2.66 lbs in a 1000w 4x4 tent id be a lot more doubtful and probably wouldnt have posted it. But in a 5x5 where there's room for the plants to breath in all of that hot HPS lighting, 1000 grams from a 1000w hps seems very realistic to me.

Your guess is as good as mine, but he didnt mention any CO2 in the details up top. Just coco and a solid nutrient regimen. I doubt co2 would even do anything in a 5x5 with only a 1000w hps. Plus he did mention he is using a big exhaust fan and an intake fan.

You do realize how hard it truly is to get a gram per watt even in the most dialed of setups with multiple lamps and cross lighting right? The commercial setups do it and then some on a consistent basis but from those pix and that tent setup...he got between 1.5 and maybe...maybe 2 pounds tops of trimmed dried and cured decent flower. And you can take that to the bank. Oh..btw..co2 if you can keep it in an enclosed area and use it right makes a HUGE difference. No way he got 2.77 pounds in a 5x5 tent with a thouie without it. And from the pix..he didn't anyways. Don't believe it. Because he didn't. Another in a long list of forum grower bullshit yield lies. The internet is rife with them .

Heh, just the other day I saw a bunch of the HPS boys on here were boasting how they not only pull 1 gram per watt, but as much as like 1.2 grams per watt from their SE HPS setups. But I am aware how hard a gram per watt is to achieve with HPS. I've rarely seen it done before, and never in person. Id love to see those 1.2 gram per watt pulls the hps bois claim though. :bigjoint:

Looking at his feedings, lineup, and overall setup though, I think the dude has a good idea of what he was doing. And again, if it was a 4x4, id be skeptical as hell. But in a 5x5 tent, it'd be a lot easier to make full use of the light since heat is much less problematic and you can fill in a pretty large space with plants to really spread the load of the light out. You wouldnt have any issues with light stress in a 5x5 with a 1000w hps.

I guess he did maybe pull a bit less than 2.66 though, actually doing the math if 36 jars are filled with 28 grams of bud each that's 2.34 pounds not 2.66. And that's of the good quality buds.

Then he has all of this bud he had to toss due to bud rot. Looks like quite a bit too. Plus the trim.

" Drying chunks on screen to speed up drying" quote taken from link. Also looks like 17 jars total to me. Both pics are the same jars, look at the labels you can tell. So at 2oz stuffed per jar thats 34oz.

Bonus question for @skoomd , how much vendable bud do think fits in a 1qt mason jar?

since1991 · Apr 5, 2018

He didn't get what he claimed. He got 1.5 to 1.75 of fully dried sellable or smokable bud and I bet he left a lot of not fully trimmed leaf on the main flowers. Nothing spectacular to see here. He didn't do bad...he didn't knock it out of the park either. Scratch that. .If what's on the screen is botrytis infected...he got a C- crop at best.

There we go. Houston we found the problem. Welp, case closed. Glad you noticed that.

An ounce to 1.5 ounces. 1.5 if it's really dense stuff. And that's accounting for breathing room up top. I mean it's not like I dont grow lol, I know how much goes in a jar. This is the densest strain ive grown or even had my hands on, same plant in my avatar. I could count on 1 hand how many buds weighed less than 1 gram.

Yep, glad booms noticed the jars being the same ones. However reading the album he pulled the bud rot stuff out immediately after noticing it a few weeks before harvest.

It's even been proven in several studies that having light that's more diffuse/uniform flat out boosts photosythesis, yields, crop quality, plant health, etc.

No it hasn't. Not in the way you mean here at least. Yes diffuse lighting is better, but only up to a point. You already get plenty diffuse lighting from a 1 COB per sqft setup already. There is no evidence that spreading it out even further actually has significant benefit. Let alone going over the top like using 36 strips.

I've seen side-by-side grows where there was no difference in doubling the number of COBs. Well, maybe half a percent, but that's impossible to say for sure because that's well inside margin of error.

But yeah going for a 55% efficient system obviously does have a significant impact on g/W figures. g/W is pretty meaningless when you use leds. Especially when you use a system which is almost twice as efficient as an HPS system. Makes sense you get double the g/W then too.

Besides, people have gotten 1.9g/W and higher from sub 50% efficient COBs

I'm all for recognizing the massive benefits of using COBs and led strips in reducing electricity costs (usually the largest cost of a grow), but lets not exaggerate things either.

3 pounds from a 1000W HPS DE in a 5x5 tent isn't that weird. That's pretty standard isn't it? Although I must agree that my cola's of that size grow did indeed look a lot bigger.

I would generally get 3 pounds from a Gavita 1000W DE. Even though usually some things would go wrong along the way. I'm glad I transferred to COB lights though. Had much less heat issues (or in fact issues in general) with those and yields went way up.

When comparing HPS to led buds, I feel that led buds do end up a bit more compact. So they weighed more than my HPS yields even though they did look smaller to me before I weighed it up.

His rig is running at 55% efficiency (177 lumen/w) after driver loss just thought id share.

Yeah I am sure that's it

There's no way larf was even 5
total crop. And that's assuming he even counted it, which who knows....

It's funny when HPS fanboys get all butthurt because they physically can't pull these kind of LED yields in the same space. I'd love to see a single hps or DEHPS grower who has pulled over 1500 grams in a 5x5 tent (let alone 4 pounds), I dont even care if that includes larf. 1800 grams of straight larf in a 5x5 tent isnt even doable with HPS. (Which is funny because you're crying over a massive LED yield that's almost entirely rock hard top shelf bud because it may or may not contain some tiny amount of larf.)

You won't find any who have though. Or if there is one out there, I'd love to hear how many thousands of dollars worth of AC they had to pump in there to keep those orange emitted space heaters cool enough.

That's cool. What I was saying was if I counted every lil small thing I'd be up there to but I don't. Just the best stuff gets counted in & the rest goes to bho.
For Instence. I've been averaging 1200g popcorn or smallish each run that goes to oil. But it could easily be trimmed for days & go to the bags. That 1200 is not counted in my weights but is most likely by others when you're hearing #'s over 1.5 that aren't some special dozen plant light sog.
Just not realistic.

Nonsense, 1.5g/W and up is easily done with good quality led fixtures. And yes I also only weigh the product that I can sell. Although I would mention the fluff weights too. Especially when doing experiments to lower the ratio of primo/fluf

I really disagree with your idea of how much diffusion you can have has a limit. Because it doesnt matter if it's 1 cob sq/ft or 100 cobs sq/ft, you still get increased canopy penetration via more angles of light to get through the foliage.

And adding more sources of light @ the same overall output increases the "goldilocks zone" of optimal light intensity, becase the PPFD down at the usual distance (say 18") will stay the same, but as you movecloser to the lights, it is lower than with fewer emitters.

@nfhiggs did some great illustrations on this, please check them out.

Here's what it looks like with a lot of emitters

And back to how that can increase yields - The more lights you have the closer your plants can get without bleaching/stress. And the range at which the PPFD is optimal is larger. So your plants run much less risk of getting light stressed, which boviously hurts your yields.

Despite what forum growers claim...3 pounds per 1000 watt is very very difficult. Much easier with double ended 1000 watt ups but if it's your only lamp...its not that easy as well. And with single ended 1000 watt hps...nope. Especially air cooled (waste of light) and no co2. The average home hobbyist cultivator with a tent or an average sized room using a couple 1000 watt single ended can expect 2 pounds per and that's pushing it. Really depends on how dialed your room and strain is (strain choice is huge) and how well you know that strains particulars. Anyone that's grown consistently for any decent amount of time (a bonifide grower) can tell you the truth and the facts. 3 pounds a single ended? Hell no. Anyone that tells you so I would be suspect. Especially if it's a home hobby setup with just one light or two..and they say it's easy.

since1991 · Apr 5, 2018

If 2 or 3 pounds per 1000 watt se was the norm or standard..every swinging dick out there would be just crushing it. You led growers would prolly of NEVER heard of the technology. Lol. Nope. Not happening. The truth and the facts are that 90% of home cultivators with 1000 watt se lamps are getting 1.5 to 2 lbs of trimmed dried and cured flower. Period!!! And to hit 2 consistently are the growers with sealed rooms. Running open reflectors...gas..and mini splits/sealed rooms. These are the facts. This is the truth. I am no bullshitter. Anyone that claims stupid weight numbers is either lying their ass off. Or growing basement boogie pig yielders that don't get you high like Big Bud or some other garbage. And counting wet weight .

Problem here is that your "Goldilocks Zone" falls from 500umoles to 250umols in what - 6"??
That's the little dick led syndrome many speak of. Shows that you can have all the ppf you want spread around the top of your growing space but doesn't mean your getting strong enough light down low to produce anything of good quality

since1991 · Apr 5, 2018

I am just gonna say it. There are a lot of third grow pros (or act like it - pros can see through the bowshit) on these forums. Especially riu. And the weight claims are just ridiculous. Again..the pros that know what time of day it is can see right through it. The CHM crowd started to get out of hand as well. Shit like "equals a thousand watt"...or even a sixer. C'mon now. With cmh...I know for a fact what they are capable of. Got several grow bros that use em. And some of the forum claims...that dog don't hunt. Lol
