I am currently in the midst of designing a building for agriculture. I am looking for suggestions on equiptment for a 100'x20'x12' room. I need to be able to control the humidity and temperature. It also must be well filtered and cleaned. I need to be able to make changes quickly. Essentially I will have 4 of these rooms. They should all be able to be hooked up to a computer control system.

Any suggestions would be greatly appreciated. If you have a suggestion for a contractor capable of this work on the East coast (Halifax N.S) it would be great as well.

Thanks in advance guys!
