I need some input on this one.
We’re moving our winter indoor growing operation out of a 10×10 space and into this trailer.
The side walls are already insulated, I already have spray foam for the ceiling, I’m removing the rack, and I’m planning to skirt the outside.
The biggest thing I’m thinking about now is humidity.
We’ll be watering in here, there will be a lot of plants, and this is going to be a fairly permanent setup for a while.
I’m trying to do it on a very low budget, but I also don’t want to build something cheap now and create a moisture problem I regret later.
So if you’ve built a grow room, greenhouse, trailer conversion, mushroom room, or any other high-humidity space:
What materials held up well?
What would you absolutely avoid?
And if you had to build this thing on a tight budget, what would you prioritize first?
I’ve got the basic plan.
Now I’m looking for the smartest low-cost way to finish the interior.
