2 Pounds Per Light

All else being equal an easier way to accomplish this is to increase your canopy size. How can you increase your canopy size? Think in 3 dimensions. So in other words Vertical grow. When you bare the light (no reflector) the problem is your loose some intensity. So how do you correct that problem? Well you bring the plants closer. Since the heat is less since (in therory you get 2X's the light/heat in one direction if you use a reflector (under perfect reflection, which doesnt happen but for illustration purposes lets pretend).

Also SOG is probably the way you want to go since in order to fill a vertical canopy its going to take a bit longer so with more plants you can make up for this and cut down on veg time. Also you want some overlapping of the stem with the plant below it so there is no wasted canopy. so you dont really want the plant under each other but you want some overlap since the base of the stem doesnt produce any bud.



If anyone thinks this is impossible: Go here --> https://www.rollitup.org/hydroponics-aeroponics/149998-heaths-flooded-tube-vertical.html 46oz 1 600W light. Granted Heath does a lot of things right and his strain was created for this kind of production, but you get the general idea. The funny thing is how low maintenance he makes his design, its easier to run than many ppl making 1/2 the production. There are many different designs that can accomplish the same thing, so this is not the only one. An interesting solution would be one that can expand/contract so you can easily change the distance to the light to accomodate different strains in different grows.

Once you have the growing down it becomes just an engineering problem and a rather easy one. Grab a light meter see where you are placing your plants now and how many lumens they are getting, then rehang the bulb vertically and go around the light and try to get similar lumens and the shape of the canopy pretty much draws itself. Once you tune this for your veg period/amount of strech for your strain its should be rather simple. If you really wanted to maximize I would imagine a combination between SOG and ScrOG would be a reasonable solution if you wanted to deal with the whole screen issue, but quite clearly its doable with only SOG. Just some observations I have made, I dont really care to debate it, take the information or dont.

so whats up pahudson how are you going to accomplish this??
I have taken into consideration many of the opinions given. I have 1 light with 9 plants, topped a few times covering a 5x5 area. I have some smaller plants covering the same sq footage, but there are 16 and 25 of them. So I am trying different configurations out. To be honest I really like the way the 9 plants are looking. Because they were topped a few times they are very bushy with tons of tops on them and they are completely covering the whole 25 sq ft. They are rocking with thick stalks and lots of green leaves. Another observation is that they are taking in quite a bit of water, basically every other day because they are "older" plants. It makes me feel like they are well established and capable of producing some good weight. Of course time will tell. In terms of air, I have installed an inline fan and I have it coming on once per hour for 15 mins to change the air. All in all growth is good, all of the plants appear healthy and green. Cant wait for the final verdict. As a side note, I have completely eliminated thrips with DE. This stuff is unbelievable in so many ways, effectiveness and how damn cheap it is. I had been battling thrips for probably 6 months and after dusting the plants, dirt, floors and cracks there are absolutely none left. I can't find a living insect anywhere in there. Great stuff, just thought I would pass it along.

Thank you for posting, this is basically what I have been doing and unfortunately, with the strain I have they just grow all over each other and some plants actually die off. 9 is working fantastic right now. 16 even seems like its too many for me with this strain. I do appreciate the advice, this thread has a lot of great information in it and just because your opinion might not be for me, it could help someone else. Good stuff.

No problem just throwing some ideas out there.

Have you tried going 12/12 from clone with no veg instead of vegging to 2 ft? maybe an idea for another grow or mix in a plant or 2 with this method next time and see if it creates something that might work for you if you dont want to commit to it all at once. Take the no veg ones and put the pot on a pedistal to match the canopy height, also with this method you might be able to reduce the pot size or go with a skinny deeper pot to get more per sq ft.

2 lb per 1000 h.p.s light is good very good,but all the grow's that i have evr seen home and abroad all have one thing in common and that is just the one plant vegging for week's and week's till she is big enougth to throw her weight around.But there are a few thing's that you may want to think about before doing one of these one plant big yeild grow's and that is they take on average 6/8 week of veg then 9/14 week of flowering i persanaly would much rather do a few more plants,and veg for 4 week getting the plant's up to the 1/1/2ft range and then flower for 8 week.This is the only way to grow 4 harvest a year,do not try to beat the 2 lb per palnt just add more lights and grow more plant's.By doing this you are always gonna have good smoke to hand just be careful not to get into doing too many 20 plant's is about ok each one yeilding round about min 9 ounce dry max 13/14.But one thing that i did take from the clip on you tube in the 2lb challange was advanced nutes are by far the best on the market and i aint used anything to match this brand yet peace ....tyke.....................................
 
beds make a big difference because your shit can veg way bigger.. if ur gunna use 16. i may wanna flip ur lights at just over a foot tall... the less plants you have in the space the more veg time they deserve... frankly i've had wayyyyyyy better buds when i've used less plants and i've yielded more...if u put too many plants in you will end up with a shit ton of small buds....when all the weight is in big buds....if u want real suggestions i would space the plants apart farther in 5 gallon pots and do them in rows of 3x3... 9 plants ...give um an extra week to veg...dont forget to lolipop... also i remove all the fan leaves on the main stock except the crown.. im not getting two a light.. but im getting more than 1 a light with 600s
 
I grow sog 32 plants under a 1000w and I hover between just under and just over 2 lbs per light. IMO sog is the way to go if you really wanna get over 2lbs. I think all ways of growing could prob put out over 2lbs per 1000w if really dialed in and perfeted.

I'm curious... what are you growing, and how tall are they when you flip?
I've done 20 GDP under 1000, and seem to average about 1.25lb (flipped at about 12").

Ok how many would you put under a 1000 watt hps?
I use a 5 gallon perlite bucket. Density of 6 or 8, depending on which strain im growing. CO2, good airflow, temps and humidity under control, light mover, 1000w hortilux super, very hi water usage, moderate yielding strains.

I also have a 12-12 stage 1 light zone whereas I can boost the density up to 18 for about 2-3 weeks, which increases the overall yield per 1000w. After the plants get as high as the tomato cage, they get final prune, bent and tied up and then go under the stage 2 maturing lights for 4-6 weeks.

Lastly is the finishing few days whereas I take them out from under the intense light and into areas which only get partial side lighting. I also let them dry out for those 2-3 days, kinda like a final ripening stage.

I calculate my average about 30oz/56days/1000w or roughly .85g/watt.

When I started growing, I was .35g/watt. Strain selection, light movers, better root management, CO2, bulb upgrade - in that order - where the big improvements.

Those numbers were with a few different strains like OGK and PK. You definately need a real bomb clone or mother to get to the 2lb mark. I flip between 8-12" 10 is what I like. I think you might do better with some more plants. 1.25 hmm, definately find some solid mothers, use CO2 if youre not using CO2 you will not hit the 2lb mark. High nutrient ppm and high CO2 concentration there are schedules and measurements and what not all over RIU. You really just need to have every little bit of your space maxed out and dialed in, doing as much as you can. You can't skip on anything. And as I said a high yielding strain is important.
 
big plants, buddding or not, drink a lot of water when they are growing. I use 5 gal buckets under 1000w hps now and these girls can drink! I am putting 2 gallons on each bucket every 3rd day. I realize that is quite ofte n and to keep the the size of plant and its rate of growth i should use larger container. Magazine i have show 10 ggal grow buckets which i think ill trys since i only scrog 4-6 plants ill have space. I personally love scroggin . Its a blast for myself to watch the explosion of plant material from grow to bloom switch! jsut awesome! I usually get 3-4 oz a plant in soil. I learned it you can harness the power of the 40/60 phenomena (stretch basically) of the bloom cycle you can increase your yield using scrog. I mean when to stop training after the onset of bloom. I have stopped training as soon as i switched to 12/12 and had arm length colas! and than ive trained 2 weeks into the bloom cycle and had more buds but a lot were bent and i had more sq ftage used. They are definitely two good ways to try a scrog. I would recommend either cuz jsut scroggin alone can get you way more bud than natural bush growing.

I will warn you though that if you do numbers that high you HAVE to remove leaves or you will be growing 90% leaf =)
I will warn you that this it total rubbish. Obviously this guy is posing, doesn't understand botany. What does he think drives leaf production, some crap like "Liquid Karma"?

Also, look into the ideal climate for cannabis. (temperature, humidity, CO2, etc.)

Learn how to water properly. Water on as close to a regular schedule as possible.

Know what is in your medium/nutrition. Cannabis needs 14 different nutrients, not three. Learn the proper amounts at proper times. Mel Frank has a lot to say about this.

Don't try to reinvent the wheel and do something fucking stupid. Look into what farmers and commercial agriculture is doing. Realize that these guys went to school to grow plants and most likely you did not.

Its all about the roots. But i thought you should know that? Just cause we have good mediums on hand doesnt mean its not a limiting factor. Your basicly questioning soil vs hydro. You may think you know alot from reading. I think i know more from experiance.
medium does have an impact on yield. I use soil and you can have shitty soil with badass nutes and it just doesn't do as good. pretty much if you don't have ff ocean you aint doing it right

i consistently yielded 9-10 lbs with 5 x 1000w lights on a 70-75 day turn around with ~20 plants per light under xxxl hoods. This is on a perpetual system where the ladies get ~8 weeks of veg from clone to 12/12. Your plants per light is not the problem imho i think it is right around where it should be. There are hundreds of factors that are impossible for anyone to diagnose with the limited information we have. It may be something as simple as the plants wanting larger than 3 gal pots or the strain just not being a big yielder.

I recommend you add some actual soil to your pro-mix. I always used 1:1 Sunshine #4 (same shit as promix) and Fox Farm OF. You have all of the flowering nutes u need (i think) but you are missing the microbials and such that live in the medium and help the roots and the plant as a whole grow. This is just a suggestion, there are hundred hydro products on the market that will do the same thing, but i have always had great success with FFOF in my not so soil-less medium.

Big yield ...low quality!

Dangerous too!

I have yet to see a strain with huge yield that is of top quality!

I don't always agree with uncle Ben but look at that thing in front of his face!!!
Fill a room with those and surely you would get 2 LBS
And he is the only one calling BS??
Seems to me a veteran like him with pics to prove a substantial yield would be saying it COULD be done!
But no he says BS!
Unless you use substances similar to the type listed above it will not happen.
If you choose a large producing strain don't expect top quality.
If you choose a high quality strain don't expect high yield.
If you say you can???... post pictures and methods otherwise it is just HOT AIR!!
dlively11 is the only one that looks like he is capable of pulling it off!

But I saw more than 1 light in the pic and he said he used gravity.
Can anyone tell me the active
ingredients in gravity...Oh ya they are listed above and gravity has been pulled of the shelves!
Everyone was doing it.
Some got caught and some got away with reformulating or changing names.
Without calling any
companies out you can figure out who they are!

But 2 LBS per light is very tough!
I for one would like to see it...with pics
I am always trying to tweak the last gram out of my girls also.
So is someone willing to teach me something new.

Respectfully
shag
