I wish i could but my wife would prob not like me setting up anywhere but the shop. But f yea im waiting on the electric company to upgrade my power.
Commercial ac units vs ideal air 5 ton mega split

I just wanted to add here, in respect to seeds/cuttings, I am also getting ready to build out a small warehouse grow, and I would not let cuttings/clones from somewhere else get anywhere near that warehouse. The smart thing to do is grow from seed and select the mothers yourself. Can you imagine, it only takes 1 microscopic sized pest to hitch a ride on that cut into your warehouse and cause a total disaster.

That doesn't always do it. It's amazing how inarticulate some people can be.
Exactly . I would not run an op this size with blind genetics . Cheaping out on Ac is already one thing ... genetics are the most important thing here .
I am waiting for some new cuts from a buddy . They will come in soil unfortunately. I don’t even like soil in my house ! Being a coco guy . I will quarantine until I can take my own cut and destroy them !
I saw something yesterday that reminded me of this. It said the main reasons people fail in business is obscurity. That you might have the best food but if no one knows about they don't come to eat. Kinda reminds me of this you can grow the best strains from seed but they will never have the name recognition that clone only cuts have. At the shop how are they gonna choose, are they gonna pick something they never heard of before or the famous strains they have heard of and wanted to try.

I dunno, many consumers are so dumb and just go by the THC %. They also look for frosty nugs. Smell sells so good smelling nugs sell. Yeah there will always be a place on the shelf for well known strains but many people love to buy new strains they never heard of provided they test high, look and smell good.

cdecided.cheaping out on ac? What u mean?

Thats where ur skillz come in to play. Top shelf shit is as much grower talent as it is strain. If my shit looks crazy badass without an out of place hair or crystal smells how it looks taste how it smells and just stands out in a jar idc what its called or who heard of it. It will demand attention. Plus i just got to sell dispensaries and they will be the ones who going to take the closest look at it.

Here is a bit of info some might find helpful. Im sure some guys will argue it but figured i would share anyway. Its about how much cooling u need for lighting. Idk why the guy uses watts for ac instead of btu since not every ac will use same amount of watts to produce btu of cooling. But anyway.
Calculating Heat Load from Lighting Fixtures
Whenever doing heat-load calculations, we must always count 100% of the fixture wattage-any fixture's wattage-as heat, regardless of efficiencies at the source. In any enclosed space, virtually all of the light produced by a lighting fixture is eventually absorbed by surrounding materials (walls, ceilings, etc.). When light gets absorbed by these materials, photons are converted into heat.
New lighting technologies, such as LEDs, allow luminaires to produce light more efficiently, or with higher efficacy than incandescent lamps. This means that we get more lumens per watt; however, heat per watt is constant. What matters is that fewer watts are used to produce comparable brightness, not that these fixtures somehow produce less heat for the wattage that they consume.
1 watt of electricity used by a luminaire = 3.412 BTUs per hour
The same math works for any lighting fixture.
For average industrial heat-pump or electric air-conditioner types of HVAC equipment, it takes approximately 0.4 watts of cooling power to offset each 1 watt of power consumed by a light source. Smaller-scale HVAC systems might require more power than this, and certain specialized systems (such as evaporative coolers) may use somewhat less, but this is a useful generalization for most applications.
Occasionally users have commented, "I work in a cold climate, and the tungsten light fixtures provide heating to my space. If I change over to more energy-efficient lighting, I'll then have to use the HVAC system for heat, which would cancel out any energy savings." It is true that in cold environments some additional heating may be required due to the lower heat output of LEDs, but there will still be overall savings in the system. Industrial heating equipment utilizes energy sources like natural gas that are much less expensive for producing heat than electricity. In addition, it is much better at sending heat only where it's needed, rather than letting it pool unused in ceilings.
Some people include Carbon Footprint savings on an ROI spreadsheet, because it can help sell the green aspect of energy-efficient lighting. This varies by region, but an average calculation for many U.S. locations is 1.5 pounds (o.68kg) of CO2 per kilowatt-hour of electricity.
1 watt at luminaire = 3.412 BTUs per hour
1 watt at luminaire = 0.4 watts of air conditioning
1 watt at luminaire = 0.0015 pounds (0.00068kg) of CO2 per hour

If you were to build a room with say ten 1kW SE HPS lights and you valued them at 3412 BTU/hr each (34,412 BTU/hr) and tried to cool that room with a 3 ton (36,000 BTU/hr) AC unit it wouldn't be able to keep up. I have done 3 tons on 8 lights before and it was a barely type situation, summer heat even at night it couldn't keep up but in the winter it managed to hold lower 80's. So I think a 1kW SE HPS is somewhere in the 4500 - 5000 BTU/hr range. When commercial growers did light for light swaps, SE to DE HPS many learned that when both lights were run at 1000 watt setting the DE lights were putting out more heat and AC units were undersized on larger grows with many lights. That extra 500 - 1000 BTU/hr per light adds up and on a 60 light grow it could put you 5 tons short if you were running at the limits of your 25 ton AC system with the SE lights.
Something about the HPS lighting puts off a lot of heat, perhaps it's the infrared spectrum? 3.412 BTU/hr per watt of HPS will come up short IME.

I think that if you figure at 3.412 BtU per watt that only takes into account the light not the heatload of the room or any other things going on the room. That's why people use about 5500-6000 for de 1000. I believe if you were accurately to add up all watts used in the room from dehuey to pumps and everything as well as the heatload for the room and then figure your lights at the 3.412 that you would come up with the right number. But every room is built different and in different climates so the majority of us just go off a more simple formula of so many btu per fixture.

It did seem a little low to me as well. To me it seems a se puts out more heat than a de. The slimline gavitas ballast stays cool to the touch. Its been a while since i saw a se in action but i remember they got hot as fuck. The guy did say that would only cover the light load.
Electrician starting my building today.. Pretty stoked up about it..

Its been so long since I've ran a single ended bulb without an ac hood I can't say for certain. I remember it was in a mobile home and they have fairly low ceilings so I feel like I could get it closer to canopy than my de. I also have the slim line gavitas and the ballast section is not very hot but I was in there yesterday trying branches to the stakes and they were def very hot on the top of my head. All I know for sure is that 24kbtu seems to be up to the job of 4 of the gavitas. I actually made a mistake when setting temp last nite and when checked this morning room was setting at 72 after running all nite. Oh and that's with lights at 115% so that's like 4600 watts or so.

Yea my friend has 5 tons on 8 and its def running fine. Has 9tons over 48 t5 and its got it. His 12 gavita room he has 4 tons but he is only at 600 watts cuz throwing breakers. Im just going with manufacture specs and say u need 4000 btu for 1 gavita. That only eliminates the hat grom the light got to add in dehu and C2 generator.
