Many growers are going sealed these days and with good reason.....
Here are a couple benefits off the top of my head:
-You no longer pump mj fragrance all over your 'hood.
-Constant perfect co2 levels.
-Less points of entry for pests and disease.
-Climate control does not depend on outside factors.
-Gone are tell tale vents visible from outside.
-Sealed rooms generally run a lot quieter.
I am sure other folks can think of more advantages?
