I'm not sure why some people think that 3 pounds per light is not achievable. I haven't personally done it but of course it can be done. If you didn't think it was possible, you may limit what you can learn. If I'm getting over 2 pounds in RDWC with some of the strains that I'm working with, I know there's other strains that can yield more. That doesn't mean that you need months of veg either. I like the idea of really packing in plants and using more space than a 4x4'. Maybe like a 5'-6' space with a Gavita. Third Coast on here says he gets 2 pounds with his Gavita on the 600 watt setting. I got close to 2 pounds on the 600 watt setting in one of my tents with a Lumatek. I'm not sure why certain people like to argue all day. We are here to share and learn from each other.

It has to be done with soil, because that is what I grow in.

Weird how most people aren't interested in how to achieve that, but only in a stupid theoretical debate.
IT IS POSSIBLE /end thread. The next thread should be about how.
I feel sad for those who think it is not at all possible and will never have a decent result in their live.

I cannot attest to vertical but 3lbs is alot of biomass in a small horizontal footprint, not impossible but alot.

I do believe most "elites" have a gram per watt potential and many have 2.5 if not 3 lb per light potential if you have all the right inputs. I think we have to add the narrative desirable strains.

Yield can be manipulated by technique but is ultimately dictated by genetics.

Back in 2001-02 a friend and I did just under 6 (5 3/4) on with aeroponics using movers and gas and this strain (but not this specific cut)


fwiw the plant pictured was grown in peat, ewc perilite and EJ, aka completely organic.

It was a first run and only 3/4 of the plants were this strain. The others were of another strain that did not perform nearly as well, but had superior medicinal qualities (both were high quality demanding similar market appreciation). However not that specific cut. This cat was my friend, student and partner at the time (RIP), he used to post to OG (circa 2001 ish). It is not beyond the realm of possibility he posted the shows on og

long story short, I culled the strain that yielded close to 3 per light in that system, frankly because it tasted like tobacco, my criteria was focused on differing qualities than that of my partner. The strain I wanted to focus on yielded less than 2 lbs per light in the same system and needed topping and lst to perform adequately. Needless to say the tension from that decision basically ruined our friendship. He had one vision, I had another.

That said since I have been here (08ish) and started growing many of the "common elites". That being said I believe most "elites" have a gram per watt potential and many have 2.5 - 3 lb per light potential if you have all the right inputs.

Your plants will only grow as fast as the slowest input in your system.

many people dont think that small scale growers are entitled to opinions on big lights

1.36 grams per watt is what we're talking about, thats a high yield, but i have achieved that and above on many occasions with horizontal modular scrogs in organic soil, you just need good soil and to make sure there are no gaps in the canopy.

ive even managed 1.2 gpw with pre-98 bubba kush, a cut many people drop for its low yeilds. get to know your strains/cuts and you will get the best out of them if you are prepared to make sure that no light is wasted.

The rule of thumb when reading about yields on icmag (and other cannabis forums) is the same as the rule of thumb when a man tells you how many women he has slept with -- take the number and divide by three for the accurate count.


If there was some way to film a grow from start to finish with no cut-takes or editing, objectively shot by a third party, and then processed and weighed by that same objective third party, all culminating in a 3lb pile of herb on a table...okay. Otherwise, I'll go with my normal opinion, which is that 99% of you guys are full of shit from A to Z and just want to be the big man on campus...on an internet forum. Not calling out anybody in particular, but big claims require big proof, and I have NEVER seen anything close to that sort of evidence posted on this or any other site.

That pretty much sums up the idea I just worked out plus some more details like the wattage needs to be checked too. It would be 1lb for 320W with 5 low yielding plants.
Sam could help organise it all if he fancies some action, he lives 30 minutes from here.

It would be very valuable to show that, especially since I am not a good grower at all, I do 90% wrong and 10% right. If I can get 1.4 gpw so can everybody, but first of all you need to know it's possible.

Oh sure three pounds a light is possible, but to get quality not hay, the devil is in the details. I knew a guy that grew White Russian, called it the lotto cut. He would pull MASSIVE yields using GH and ebb n gro system. It was good for sure but wasn't grade A.
Genetics is the first place to start, find a strain and dial it. Then choose a style of growing, vert, sog, aero, etc and start vegging. Keep vegging lol.

The other key will be environment. It has to be perfect ALL the time, and the water, soil, nutes all high quality and dialed. Then it comes down to growing. May take many runs to find that large yielding pheno that preforms well in your environment. Some strains do better with different styles of growing. Example, PPP yields like mad in hydro with nice flavor and potent high, in soil its bland and average yielding.
Like anything else of course it is possible, just do you have the talent, discipline, resources, and patience to make it happen?

at the end of the day though, if you are the doubting type, nothing that you could post on an internet forum would be conclusive proof.

It's easy to get 3 pounds of wet, poorly trimmed, extra stemmy, bush mastered, phospholoaded, hairy, no frost, bud/larf mixture. Three pounds of quality might come out in 1 of every 20,000 grows. Genetics, environment, veg time and lots of trellising. I'm sure it can be done, just wouldn't be practical for a commercial grow.
