What to add to my grow shed?

[That_grower21]

I’m in the process of turning my shed into a big grow room, (used to grow in my spare bedroom) looking for things to add to the shed to make the ultimate grow shed!! Already have pricey equipment such as lighting, c02, a/c, thinking about doing a rwdc setup after this grow is finished. Open to stuff to add to the grow that will even better the final product, should I put reflective Mylar up or put drywall and paint white? Money isn’t a problem just looking to make the best possible grow setup. Thanks!!!

mylar is great but very,very delicate. flashgro is what i used and am very happy with it, if you want to mount something to the wall later it won't be destroyed like mylar.
insulation , poly and densshield is a must IMO if you want to be able to control heat and humidity easily.
and of course proper intake and exhaust fans
