I work at a distribution center for Lowes and we get it for 50 a pop. I used it for the tops and bottoms af each enclosure. The sides are pvc out door moulding boards.
Worked very well. Word of advice, the unfinished edges absorb stains. I silicone the inside seams of each setup but the top one leaked and left a brown stain. I've bleached most of it out but wasn't able to completely get it out. Seal the inside edges well!!!. Holds humidity well and allows flex watt heat through. Also if stacking, get some felt furniture pads/feet for the bottom corners. This Allows just enough space for the flex watt to breath
