10 x 7 x 7 shed complete noob trying DWC HHT helpful info needed :D on a budget

So this is my very first grow popping the cherry flavored bud for the first time in my life
a little nervous, boggled at the thought seemed simple enough at first, bought the shed
built the inner frame insulated it with fiberglass put up walls cardboard sheets 4'x8' all
around the inside and roof cocked with outdoor silicone the outside seemsof the shed to make
more safer from bugs and what not, next its is the reflective film but need a cheap efficient

one that you guys might recommend

budget build little by little so its gonna take time will post up pix as time flows onward

Id say flat white paint.. or b/w poly..jmo

Flat white paint or nothing. Either would be fine for a first grow until you get enough money to do what you want.

just ordered the mylar poly black & white and also mylar reflective file 2 mil 48" x 100' now to put that shit up and take pics

Imo u just wasted money on the mylar...but to each their own let's see them pix
