Large grow room

I have a warehouse space in Michigan that is 90 X 100' X 17' ceiling height. I will be doing a 72 plant grow having much more space than I need what size L X W X H would I ideally build the rooms.

You want your veg space about half to a third of the size of your flowering space. I assume you'll be growing big plants with a small count so you may want to aim for a veg room on the larger end of the spectrum. I can't give you the length and width, but lighting dependent, I would go with 10' ceilings and Double ended 1000w setups. There are so many ways to go about it, that is why consultants are raking in the scrilla... Maybe a commercial grower will chime in...

Good luck

Wow, 9000SF, you can grow a lot more than 72 plants, or at least grow big plants.

2 plants per light in 20 gallon pots. Run 2 18kw rooms, Each with 5 ton minisplit and 12 flame burner. Just depends. How far up north are you? 200 amp service?

I'll consult. I'm not far away either!

Let's say $20,000.00 USD will get you complete installation and discretion of course.

Your bills gonna be $2000 month avg, 3000 if your registered as business.

Best of luck!
