I currently grow in a tent, building a room hopefully tonight, I was thinking that thick insulation with the reflective silver on it or should I do drywall and paint bright white?
Getting ready to build my 1st room

I'd definitely go with insulation man, it'll help keep your temps more even.

I live in Maine normally mid 80s low 90s in the summer to you think I will have to use a a/c in the summer with the insulation rnint? Thanks for the help!!

Insulation for sure. Do you know the size of the room you're gonna build?
I'd do the frame then fit the insulation in between and cover it up with some plywood and paint that flat white that has titanium dioxide in it for better reflection than Mylar.

You're gonna want to do a few dry runs so you'll know the temps and humidity in there. You can always get a digital humidity/temp controller

The insulation would also be the wall it had a reflective film should that work?pseudobotanist

That's what I used to build my kiln but check what the R value of it is. I don't know how well the reflective material is tho. For my kiln the R value came out to around 7.5 I believe most housings use an R value of 13 for the walls. There's a pink one that's Xps foam board 4x8 and is 2 inches thick with an r value of 10.

I don't know what r value is, what is that? And I still plan on doing a 2x4 frame

2x4 frame is fine but I'm asking how big is your grow room going to be?
R value is the capacity that the insulation has to resist heat flow. The higher the r value, the better the insulation

Oh ok, and it's a 25x20 ft area split between 3 rooms I'll probably do an 8x8 8x8 4x8

Why don't you just split it into 2 rooms? Simple veg and flower

If you're using 2x4 framing then get some batt insulation R-13 it is the most economic. Definitely use plywood on the inside instead of drywall, it will give you the ability to mount whatever you want wherever you want.
What is your ventilation like, are you drawing air from another room or from directly outside? Outside air is generally much cooler at night than an adjacent room.
