Like all Ascent models, it features a heavy-duty powder-coated aluminum frame, 6mm twin-wall polycarbonate panels, smooth-gliding double sliding doors, adjustable roof vents, built-in rain gutters, and an included snow load kit, all backed by Grandio’s industry-leading warranty.\u003c\/p\u003e\n\u003ch3\u003eWho Is the Grandio Ascent 8x20 Best For?\u003c\/h3\u003e\n\u003cp\u003eThe Ascent 8x20 is ideal for dedicated hobby growers who need the most growing space available in a residential greenhouse.
