Be Honest! Who's getting 3lb/1k???

So correct me if I'm wrong, but one should be able to (+-) double their sq/ft coverage w well designed vert system.

Math:
Horizontal (Mag XXXL) gives soild 5x5 = 25 sq/ft

Vertical: Is the surface area of a cylinder (not incuding top & bottom) gives 2*r*3.14*h (I assume the bulb would be 2' from the plants and the height of the plant is 4') = 2*2*3.14*4 = 50 sq/ft.

Are the distances used correct? That the radius is 2 feet and the height is 4 feet? If so I need to do a vert grow! And not only b/c I can increase sq/ft, but this would fit better in the space I have, which would allow me more room to move around plants.

If I were a large scale and/or have lotsa space I can see the simplicity of horizontal, ecspecially over 4x8s as Avant is going to do next. Who really gives a ef about whether or not you pay 3k or 3.5k for electric and need a few extra lights if ur large. Its the CODB. What matters is how much net $ and how fast it moves.

I run vert with two bulbs stacked with 50 square foot of canopy in a 5 X 7 X 7 room. That is 50 square feet of grow in a 35 square foot room and I still have room to move around.

Thanks Ichbod, it was in fact your pics that made me do the math and consider doing a vert.

While I may never get that pipedream of 3 lbs, a vert seems like it may work better in my area.

Great stuff!

If you can live with a lower GPW you will get a far better quality overall. The extra cost is almost nothing compared to the increase in quality. Just adding a 600 watt bulb for a ten week flower in my area is less than $100. To me it is worth the cost to get rid of larf. Larf lowers the price of your bud and increases the time to trim. I am not sure if anyone wants to keep trimming larf run after run.

Indeed...
Larf does get to be a pain...i'm getting better at trimming now and try to pull off all the larf after stretch is done.

But sometimes i do leave a little, i plan to dabble into BHO soon...so i save trim.

Looking at your screen Ichabod, I may need to may a few of these is I want to run a couple strains to the fullest... I have a couple that really like to stretch that I never really let them do. I will need to mimic your setup to achieve their full potential.

Are those screens 2x4? that 3rd in from the left look like 1/2lbs

The screens are made of PVC pipe and I detail that here.

https://www.icmag.com/ic/showthread.php?t=242646&page=3

The screens can be more work to set up but they make it real easy to maintain your plants. I hand water and I can water a lot faster then if I had to snake around 6 plants. They also allow me to look at a plant in just seconds to find any problems with it.

Another benefit is that I can take just one plant out of the grow at a time and not disturb the others. So I can run a perpetual if I wanted to with a plant coming out every 1.5 to 2 weeks.

As for the plant third from the left I will know in about three weeks what it yields.

And yes the screens are 2 foot by 4 foot.

this is a 3lb plant...its 8 feet tall at its highest point, and its circumference would easily take 4 grown adults stretching their arms to get around it. it is probably taking up an easy 6x6 space, probably more. even with barebulb setup like Vagpuncher runs i just dont see how a single 1kw light can produce the same amount of nug. even with a raptor hood the light would not penetrate to the bottom and sides of the plant, the open sun makes every single cola even the ones on the side dense up and get very big...the colas on this plant are easily 2x the size of most strains i run indoors...

but who knows its all speculation on my part.....for horizontal setups the standard 1kw covers a 4x4-5x5 space...for verts obviously more...one centralized 1kw bulb cannot cover enough space, now if you split the bulb into three 330 watt bulbs and arranged them around the plant maybe. also, big time growers like jackmayoffer and others who run 40+ lights can hit higher yields because each 1kw light has a bit of help from its partner lights...so each 4x4 section has help since the sides of the tray will have light overlap from its neighboring trays...if that makes sense..


here are pics of my 4x4 tray, 9 plants in 2 gal pots, OG kush on drippers, that yielded just shy of 20 zips so not even 1.5 per 1kw....and one of my densest canopies to date. main reason yield was low IMO was because i chopped the entire plant at once and had about 2 zips of larf. if i harvested tops first and let the bottoms finish i could have hit 1.5...

YesProp - You pretty much validated what I sucpected to be the truth. 1.5 is very respectable, maybe 2 if you gotta really heavy producer and you're super dialed in...

Thanks!

i got 5 lbs of a 300 site coliseum with TWO vert 1kw bulbs.

prolly had 250 8 gram colas in there. that was back in the pre MMJ days, when plant count was not so much of a factor.

nowadays i rock BIG TREES, plant per light sorta deal. i can get close to 2lb/per if its the right strain. but thats a HUGE factor. OGK gets mebe 12oz per light, I have some headbandXchz and MkUltra crosses, that can do 28oz. same room, same nutes, same everything.

thats a pretty big spread.

Well put! Once dialed in it's all about the strain. And yield ain't everything, as I'm sure you know. It's about quality and the desired taste, smell and high.

1.5 is considered by me to be a very good grow.

I have never hit 2 pounds per light with GOOD genetics.

Sure, with Jammer or Critical Mass it's possible, but that's disregarding the potency.

Biggest I ever did was 93 pounds off of a 55 light room.

I routinely hit 1.5ish.

I have one time, hit just over 5 pounds from 2 1000w lights in magnum hoods horizontally over a 4.5 by 9.5 area. The right side light yielded just over 3 pounds and consisted of:

2 daywrecker
2 Legend OG
2 Schwartz
1 Bubba91 (This alone yielded 38o+ grams

The other light yielded just over two pounds with more indica dom strains wmk, w91, royal kush etc..

That is like 8 or more different strains being run under two lights and still getting that yield. The key is cinder blocks under plants to even canopy height.


All in 5 gallon smart pots, roots organic soil, and biobizz nutrients. No Co2, no AC.


It can happen but god damnit I'm restricted to tents now and it wont happen in a tent.

Anyone who says it absolutely can't happen is in denial.

and yes it can happen routinely in a vert setup.

This was my first and only vert run, again like ten-twelve different strains and I hit 5.7 with 2k. I could easily have put in a plant or two where the carbon filter is and broke 3per the first run.

Not trying to come off as cocky, just showing it can and does happen more than you'd think.

i also don't want to come off as cocky but i think most vertical growers forget to mention that the surface area of the canopy will diminish as the plant grows towards the light whearas a horizontal your canopy size stays the same.

also diffuse light from a reflector is better used and better penetrates the canopy because it doesnt come from a point source.

most vert growers would struggle to beat the gpw yields i achieve in horizontal scrog.

but at the end if the day what matters is that you find the method that works best for you and try to make the most of it in your situation.

Also i would like to mention yes vertical looks impressive you see lots of buds as well over 50 percent of them don't really get huge being your letting everything grow even the sucker buds no different then them sucker leafs on a tomato plant wasting energy but with 75 - 80 percent of the bud losing weight in the drying process and proper trimming you have very small buds once dryed which takes a shit load to make even a half of a pound i have had half pound bags almost bursting to make 227 grams and and had half pound bags of nice big buds that looked half empty but it was 227 bottom line 5448 wet grams to make 3 pounds is allot especially 1k lighting unless you veg the hell out of them then again there comes a point where 1 k won't cover a big planted area
As lighting technology gets better there very well be in a not to far future possibly 3 pounds per light i almost pulled 2.5 with 1 k will see this grow c02 added but still 1 k over 5 x 5 area scrog

With the right strain and co2, it's fairly easy to hit 3lb/1k. Growing trees, it can be done with as few as 20 plants under 2k watts w/ co2. Once got 6.5lb and had several 5.5 - 6lb harvests.

DrFever, why are assuming vertical growers don't prune and shape their plants? I certainly do as do the majority of others. While the surface area may decrease in a fully encircled vert grow, it most surely doesn't in a stadium grow. Seems like you're over-generalizing far too much in your view of vertical growing.

Beautiful VSCROG, Ichabod. How does vegging work with this?

most vert growers would struggle to beat the gpw yields i achieve in horizontal scrog.

In my limited experience, horizontal scrog had less yield per watt than vertical trees. It took more time, space, watts, and stems to get the same amount of buds with horizontal, because of the natural growth structure of the plants. Growing more stem = less efficient... thats a big reason why more plants usually means more yield all else equal.

Are your yield calculations including relative veg time/watts/space? I'd be happy to go back to horizontal scrog if I could yield more than vertical.

Yes your are correct with lights having help with partner lights thats why i like running lights in parallel so each light helps the other

2.1-2.3 are extreme's very few can pull this off in my opinion. I have only been able to muster 1.8-9 but I do not grow commercial weight oriented plants either.

Beautiful VSCROG, Ichabod. How does vegging work with this?

Vegging depends on the strain. If the strain does not stretch it is a bear to train to the screen and I end up cutting a lot out to get it one bud deep on the screen. In this case I run the light high and cause it to stretch.

If the plant stretches a lot like sour diesel does I run the light to the side of the plant to get it more compact when I tie it to the screen.

Really you just have to run the screens threw a run with the strain to tell what it does.

Thanks ICMAG readers!

This has been a very informative and civil discussion on different growing techiniques. I've learned more from your experiences than I thought possible. Hope to hear and see more of your grows!
