I used to run no veg SoG back in Missouri, did great things with it pulling a gram per watt. Also did a no veg SoG in the tent and only had 8 plants in a 2x4 where I would normally have 24 plants in my previous SoG setups.

I think when you look at the big picture, nothing beats SOG .
Let’s say you get 1gpw with SOG & 1.8 with a plant count. When you add up the space n watts n time & time caring for veg. Not to mention the trimming SOG is 100x easier .
SOG wins .

Up until 5 years ago, SOG is all it did indoors , now being legal with a plant count I had to adapt.


Where your building a new spot n LEDs .
Any thought about a couple layers ?
Or vertical?

You should see if you can get some tours of current led commercial grows, tour a few and see what works and doesn't. Are you on ig ig check out high altitude farms, they recently went with some top of the line scynce led fixtures for a run and from what Im seeing in pictures and reading in comments they didn't get the expected results. And they kill it so it's a good place to start looking.

When I see pictures of commercial led facilities they just don't look to be putting out the same per sq ft of canopy. But if you can put out 75% of hid yields and only 60% of the power it leaves you more electric, if you take that electric and use it to double layer racks you would be at 120% of what it would take to power an hid room but theoretically should be at 150% of the yield. I think thats where the efficiency comes for led on a commercial scale. Cause I've yet to see anyone in a flat commercial grow with led that looks to be getting the same weight per sq ft. And like you said a little bit of weight per sq ft makes a big difference on that scale.

I could be completely wrong just giving my opinion, also what fixtures would you use as I don't think you can build them out yourself for a commercial grow since they won't be ul listed.

Sorry I think it's actually high latitude farms

In the winter I still have to run my AC's using HPS, and with LED I would be making plenty of BTU's to heat the room especially with the planned spray foam insulation. Figuring about 9.6 tons of heat will be generated by LED in a 1500 sqft room, there will be walkways and canopy area is about 768 sqft. That doesn't include propane CO2 generator and dehumidifier heat.

I'm new to led and dont have a harvest coming down yet but halfway in, I am all about a mix of led and hps.
The heat from hps has been giving me the whillies for way to long. I even lost a large crop when an a/c shit the bed.
That wont happen with led. No a/c and you can just keep on truckin.

I think hes gonna hook up with @RainDan and buy a tractor trailer full of fatty vs lol , So they will be ul listed and of the highest quality.

Personally, if many others on site said they were gonna do this, id prob just roll my eyes and say good luck, but theres not many renfros around here , so if he attempts it, i expect they will be successful.

I think what you guys are saying about scaling up to huge size grows is interesting, i havent really seen any massive commercial grows running only LEDs, i assume theres legit reasons for this?

Just not sure what they are.

All the large led grows I've seen built so far have gone back to HPS after losing a ton of money. Not at all saying this will happen to renfro, just that I havent personally heard of large scale success.

Grams per watt seems ok but when it's the same ish gpw with less yield per sq ft it just doesnt have a advantage at scale.

Times are changing though and at some point LEDs will be very viable so maybe its now.

Ya for sure, ive seen and read a few big ops changing back to hps after making the switch, not liking the results etc...

It will be interesting to watch, especially knowing the grower

If you guys are on ig check out mangotech look at his latest post and scroll over to pictures 6-9 that in my opinion is the only way LEDs are going to be more productive atleast with the current tech and on large scale. For home growers there are so many ways to grow that led can be utilized pretty good but when you scale up even if your only losing a few grams per sq ft because of lack of penetration that still adds up to big losses fairly quick.

Fremont County up in the mountains. No thoughts of layers or vertical. I want easy peasy with a large grow, less hands on. Let the plants do the work. I will have enough work with cutting clones, potting, harvesting, checking reservoirs. I don't want to have to even touch a plant after potting until I harvest it.

Definitely need listed lights for a commercial setup, so I won't be able to build my own lights then, plus I don't want to build 96 lights. lol

If you have the space both could do nicely together. I've seen an hps 600 and a cmh 315 together, and the overlapped looked best. It wasn't a side by side it was an altogether.


I'd go cmh if it was one or the other
