under ground hydro garden.
 

Hey Hydro ron i am building a under ground hydro garden. The garden is 40 feet wide 120 feet long. Have you ever had any experience with a project like this. My biggest problem is controlling the under ground atmosphere, too damp. thanks for any suggestions. Itis12 feet under ground.

When the lights are on, should take care or the humidity. But when there off, you would need dehumidifiers, fans, blowers and whatever to achieve the correct growing environment.
