So here are the hard numbers. (See attached billing cycle of 2 grows back to back) I am running ...
18 HLG 550 V2's
2 ton Carrier mini split
1- 18,000 BTU wall heat/air unit
1- 20 cubic ft deep freezer (for storing raw processing material)
12- 8ft T5 light fixtures
2- 24 inch oscillating fans
2- 4000 sq ft dehumidifiers
1- 10 inch Hyperfan intake
1- 5 gallon water heater
1- water pump
Thats just the grow room/shop building. The electric bill is all in one to include the grow building, my home, and water well energy to provide 2 homes (my dad has a home on my property 5 months out of the year)

My home AC unit was old and inefficient. I just now upgraded the AC unit to an 18 seer heat pump and all matching Carrier air handler, 5 ton A coil, etc. So, Im sure we will see better numbers in the future.
This last run was for processors fresh frozen bud. We ended up with a 2 month veg, 10 week flower and 153 lbs of market ready product for processors. Hope this info is helpful for future growers.
I've been working with Quantum Boards for the last year or so. What wattage were you running each 550 at? Or did you vary? They look really far away from the plants in the picture but your plants are unbelievably stunning.

These HLG 550 V2's are 1000w equivalent, with a true 485w draw. I have them set per HLG's recommendations and using a PAR meter to double check. Seems to be working pretty good for us.

Yes.. we are a small craft bud producer, and do one grow at a time. Just our preference for now. We may expand next year and build another room so we can do rotation.
Thanks man I appreciate the info in this thread....I'm in Oklahoma as well and will be caring for the plants if and when my friend and his partner get the money squared away and get setup. We're also looking to do a small boutique setup, something two men can take care of full time. The commercial HVAC stuff is my main area of ignorance. I don't mean to be too vague but if theres any more info or pictures you have on this setup I'd love to see it

No prob. We have a 2 ton Carrier mini split for this room. Also pictured are the dehumidifiers...

Thank you! What kind of square footage was that room? No heat or humidity issues with that setup? Would a 4 ton minisplit be overkill?
20x30 is 600 sq ft. In the winter, if we do a fresh run, we do have to mist down the floor a couple of times a day to keep the humidity up. And summer is a bit tricky with heat. It’s been very hot lately, and we are delaying the next run for a couple weeks till it cools down a bit. A 4 ton might be a little too much. The drain line will freeze in the winter. Yes, the AC will kick on when it’s in the mid 20’s.

Yes, 8.5 lbs per light. We did the math on the first dry bud run and we got right at 500g per light after drying and curing ready for market. And yes, we were very pleased with the energy usage. You can see where we were finishing up in June and it started getting hot outside. That was our highest bill. We're taking a short break until Sept. and it cools down a bit. We're having some new flood tables installed anyways.
Have a journal for these grows?

My drain lines are indoors to a floor drain, 4 ton units. Do yours run outside or something? With my HPS lights my AC runs if it's 5 degrees outside.
Yes.. during the build out, it never occurred to me that the ac would kick in when it was that cold outside. I just plug in a heat tape strip on the drain line when it gets below freezing. Lesson learned for the next building.

It was a total of 16.5 lbs after drying and curing ?

Thanks In Advance.

Do you use a bar code scanner system? If so, which one?
Yes, it's though Brother. But we have not figured out how to link it to the Excel program. The State only requires us to use a digital seed to sale program for now. They are working on a State mandated system, but supposedly it won't go into affect until late 2020.

Try this:

Step 1

Connect your barcode scanner to your computer.

Step 2

Install any scanner software (such as a serial driver) supplied by your scanner manufacturer. If your scanner plugs into the USB port, the driver should load automatically.

Step 3

Start Excel. Click on the cell you want the scanned data to appear in.

Step 4

Scan a bar code; the data (numbers in most cases) will appear in the cell selected in Step 3. Your scanner may also have a pre-defined "Tab" or "Enter" bar code. Otherwise, you'll need to scan and press a key on the keyboard before scanning the next item.


If that doesn't work see if the scanner can export the scanned data from a session into a CSV format and then import that into excel.
