Watt to Pound Ratio (indoor)

I know it can't be exact, but with LED, controlled climate & good genetics what could an average to good grower get with say 10,000 watts? & what would be more or less needed to get 40 pounds, tysm

impossible Q to answer..depends on veg times, type of grow..eg scrog, sog, natural and talent and and and.

Not to mention is 10,000W just for lights or does than include AC etc etc etc

if you base your business plan on .6 grams per light W then anything over that is a bonus and should be easily achievable.

I will add your better off working backwards.

How much yield do you want every ? month/s.

With how much space?

Then the smarter people may be able to help ya.

You mileage may vary. 1 gram/per/watt is/was the measure of being productive grower. It is one measure of success. This usually only about the lighting. Most people dont divide their entire wattage into a grow. So someone running lights, CO2, AC vs someone just doing it with lights and fans is not considered. Obviously, lights and fans grow is going to be cheaper/per/gram. Rule of thumb 1000W=2.2lbs. People do 3-4 a light I am told.
Anyhow.
1000W=1000g.
10,000W=10,000g
10,000g= a little over 22lbs.
So, 20 -1000W HPS + associated equipment and Skill should get you there. Anyone with money can buy the equipment. Of course you need to be able to process 40lbs, deliver and start the next grow cycle all at the same time.
Easy and fun to farm on paper.

People like to say that 1 gram per watt thing.
Personally, I say that any kind of G per watt thing is meaningless.
Lucky has it right.
It's not hard to run a SOG grow, in a small space, and kill that 1 gpw level.
I've done well over 2 in a 2x2 with a 250w HID.....Metal framed, Flood and Drain hydro. Built that years ago as a dial in tool for finding the dial in for strains to be run in large flood systems. These ran big plants and hung around that 1 gpw area.

I've seen monster sized SOG's before. Stupid large plant counts.....The most I ever ran was in a 5x5 tent with 64 plants in plant warrior 1 G pots. 32 g average and a final yield of 3.46 gpw, running a 600w HID light system. Vegged to 8 inch's and flipped in place. Dr. Greenthumbs G13 was the strain.
Hesi hydro nutrients were used. Water was RO and buffered with a Ca/Mg. Kelp extract was used in place of the ROOTS and SUPERVIT Hesi products.
Temps/RH were controlled to the use of Co2, by an environmental controller. Exhaust settings on the controller were at 89F temp and 80% RH. Co2 ppms were 1000ppm. Only during bloom, and stopped at the last 2 weeks.
Watering/feeding was done daily in metered amounts that would carry the plants to the next days at lights on.
Nutrient use was 100% of the charted requirement. The use of the kelp extract is in line with kelp extract use at 5ml per gallon of feed.
Mg sulfate and K sulfate were used to increase trich and terps. The use varies for plant age/size. It is stopped at 2-3 weeks before the harvest. This will not inhibit potency.

The above #'s are from the runs notes.

Today, I run for quality, not quantity. I want to get as close to plant potentials in quality as I can.

10 kW could bring 36 lbs.

This exactly. Grams per watt means something in SOME instances, but not all so I dont believe it should be used as a standard equation. For example, I dont veg my plants. I cut from a momma and when they root, I transplant them directly under the flower lights. I'll let them harden off for a day or two then right into 12/12 for 8 weeks. To compare my 1000W to anyone elses 1000W means nothing if I dont veg under 24 hrs of light for 6 weeks then flower at 12/12 for another 8 weeks. Time scale in my instance would be more relevant than grams per watt. I could probably get nearly twice as much in a fiscal year than someone who veg with the same light watt for watt. I too am a quality over quantity kinda guy, though I'm happier if a quality crop turns out to be heavy.

It depends on the grower. You can have the best of everything and still screw things up. Biggest issue is too much. Less is better in most instances except for light and attention to things like temperature. You can have everything dialed in and if you dump a bunch of overpriced nutrients and additives into the mix you'll be right back here asking what's wrong with your plants. Good grow medium, as much light as you can get, and a good environment is all you need. After that, all the garbage they sell to enhance your plants will likely do more harm than good. A good base nutrient is all that's needed if you have the primary needs dialed in.

There's another yield measurement

grams per sq feet

Target yield 50 grams or over

These 2 type of measurement should correlate with each other to maximize yield potential.... grams/sq ft and grams/watt. In a 4x4 for example with 1000 watts light, it should be able to pull 1000 grams or over

1000 grams/16 feet = 62.5 grams per sq feet
1000 grams/1000 watts = 1 gram per watt

If the 2 measurement doesnt jibe it's either you're not maximizing yield potential for your grow space or wasting money on light electricity.

I've seen several blurple grows getting 1 g/W, I've seen several HID grows getting upwards of 1 g/W, and many COB grows claiming near 2 g/W.

Is this just the math that thing the led guy's talk about or do you have an actual lay out with veg times, light spacing, room dimensions and that sort of thing? Interested in hearing about the 10k 36 door yield.

I could get into all of that, but I'm not building a 10kW setup.

My design is maximizing efficiency, my goal is to use 2kW over one square meter, I'm looking for 2.5 kilos.

over 5 pounds in a sq meter? I'm in for the run. Link to thread please?

Once it is built.

I'm still testing the Bridgelux Vero 29 C, based on small scale performance I will decide if I should order 2kW of Vero or switch to another brand.

Everyone is screaming I'm an idiot and the Luminus or the Citizen are better than the Bridgelux. If I can manage the efficiency I'm looking for then I'll unload on the TastyLED light engines.

Almost 8.5 zips per sq ft....thats ambitious. I'd like to watch that thread as well.

How else can we put LP out of business?

No amount of light efficiency will get you 2.5kg/m2 without many other optimizations. Start with something you know you can attain. I agree with Dr. Who on all the points Lucky Luke didn't cover in reply #1

My advice is: Relax, grow some shit. See how it goes, and try to do better next time. David Blaine didn't wake up one day able to do freaky shit. In many ways the practice is the discipline.

This isn't my first rodeo, I've been waiting a decade for LED to get to this point. The space is optimized for it, aeroponics will carry the feed, I just need to find the right light source.

I'm not looking for anything outrageous like 2 g/W, that would be 4 kilos, I'm aiming a bit more conservative with 1.25 g/W. If I manage 1.5 or 1.6 g/W I'll probably have a heart attack.

I didn't mean to assume anything about your experience, and I wish you luck! SOG grows on par with Doc's are rare, and so are vertical trellis systems. Lately I have been trying to decide which one I want to try next. What is LP and why are you targeting them? I think having a sworn enemy/target is a legitimately good business strategy, I am just curious.
