12'x30'x10' grow room buildout

I am a legal, newly licensed, commercial grower and in the process of building out a 12'x30'x10' room inside a 30x30 insulated pole barn. There will be 220 electric in the building. I am here asking for ideas for the most efficient way to use the available 12x30 space for flowering and veg. I have 8 Phantom DE 1000w hps lights. I want to run 6" rockwool cubes and floraflex caps on drain tables for the simplicity and water automation. I would like everything to be as automated as possible as I cannot be there 24 hours a day 7 days a week. Please share your experiences or ideas and I am open to all. Pic below is the 30x30 slab. Thanks in advance

Do you have any limits on plant numbers? I'd separate into 2 flower rooms, and 1 mother / clone room.. run 2 4x4 flood tables in each of the flower rooms with 50-64 well rooted clones on each, don't veg at all straight clone to flower. Get a couple of 96 site cloners in your mother room and have like 5-6 2.5-3ft moms on hand all the time under T5 lighting vegging and producing clones. Run those in a soilless 5 gals. You only will have to hand water them like once every 3 or 4 days, everything else is automated with pumps and timers. Easily pull 5-6LB per month on this setup.

Are you planning to expand and use whole building? Did u put any floor drains in that slab. 2 4 light rooms with a 2 ton mini split. 2- 12x10 rooms for flower would leave you another 10x12 room for veg.

We still legal here with medical but any licenses I see are going to huge facilities. Curious is this in OK? Don't have to answer but seems one of the easier places to get a commercial license without investing a million plus dollars.

-No limits on plant numbers.
-I do not want to use the whole building for the grow.
-There are no floor drains in the slab.

This weekend I picked up a used 18 site, 5 gallon bucket, ebb and flow kit for cheap. I like the idea of 2 different flower rooms instead of 1. I may try the buckets in one flower room and rockwool cubes drain to waste in the other and see which one works more efficiently. This weekends progress pic.

Really amazing, cant wait to see the process. Good luck!

Im getting hard thinking about this. Sorry man, your on your own.

Here is an update on the grow room buildout. We haven't got to work on it as much as we'd like but its slowly coming along.

What is the climate by you year round?
Personally I would focus more on controlling the environment.

Are you insulating?
How manage air conditioning?
Water?
Seal the floor?

Building has 2” spray foam insulation. My plan is a 3 ton mini split for a/c, quest 110 for dehu, floor has been sealed, water is coming from the yard hydrant outside the building.

looks great! can't wait to see it finished

No floor drains?

Following along, looks great!

I think you undersized both your dehuey and AC for 8 lights. I have a 3 ton cooling 6 lights it barely keeps up if they are on overdrive which is 6900 watts total. Maybe if you get a name brand one it will cool better but 8k watts would be pushing it.

I also have a 50 pint and a 70 pint running at all times and need more I'm floating around 55-60 % remember that's with 6 lights so 8 should need even more.

I too had hoped to be able to run 8 lights on similar equipment but it's not gonna happen for me I'm stuck at 6k watts til I add another mini split. I'm also thinking of just grabbing a quest 225 so I make sure to have enough power for dehuey.

Not at the moment. I’ve since realized it wouldn’t be a bad idea.

this is my first go at a commercial grow build so I appreciate the advice

Grading the floor to a drain would have been titties.

That's mandatory IMO.

Yeah nothing like being able to hose down a commercial area. Ceiling, walls, lights, floor. Everything.

Plus draining hydro systems or running a DTW system can be accomplished with ease.

This really is the major type of shit that holds me back from going commercial. Such a major initial investment to do it right and it takes so long to see a return.

It is a major investment. Depending on wholesale pricing in your region the ROI could be as quick as one crop provided you get a good one lol. If starting a commercial operation in Colorado for example it would take at least 2x as long to recoop the investment as it would in Oklahoma where wholesale prices are twice as high as in Colorado. The time to start an operation in Colorado has passed, get setup in a fresh state, grab the big bucks before the market is flooded and pricing falls. Setup with efficiency (low production cost) so that when prices do fall you are already ahead of the game.
