{"product_id":"gable-series-walk-in-polycarbonate-greenhouse","title":"8.3ft Gable Roof Walk-In Polycarbonate Greenhouse Kit - Gable Series","description":"\u003cp\u003eThe Gable Series is the shape most people picture when they picture a greenhouse: straight walls, a pitched roof, a ridge down the middle, 8.3 ft wide and 7.2 ft at the ridge. Width is the whole point of it. At 8.3 ft it goes down the side of a house, along a fence line, or between the driveway and the property line where a 10 ft house simply will not go, and the pitch keeps full standing height along the middle instead of pinching you at the walls.\u003c\/p\u003e\n\u003ch3\u003eWho this one is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuy the Gable if\u003c\/strong\u003e clear width is your constraint.

Our lengths are metric\nconversions, so we publish them exactly — a 19.5 ft house is listed as\n19.5 ft, never rounded up to 20.\u003c\/p\u003e\n\u003cp\u003e8.3 ft wide in eight lengths — 6.5 ft (54 sq ft), 13 ft (108), 19.5 ft (162), 26 ft (216), 32.5 ft (270), 39 ft (324), 45.5 ft (378) and 52 ft (432 sq ft).\u003c\/p\u003e\n\u003cp\u003ePlan the inside before you pick the length. At 8.3 ft wide the usual layout is one bench down a side with a comfortable working aisle beside it, or two narrow benches with a tighter walk between them. Length is what you then buy: 54 sq ft starts seedlings, 108 gives you a real potting station, 162 to 216 covers a household's vegetables with room to move, and the top of the range at 432 sq ft is a serious growing space on a lot that was never wide enough for one. Price per square foot falls as the house gets longer, so the extra length is the cheapest growing space on this page.\u003c\/p\u003e\n\u003ch3\u003eWhat it costs, and what it costs elsewhere\u003c\/h3\u003e\n\u003cp\u003eThe Gable starts at $1,589 with curbside freight already included, and it is worth being straight about the trade: a narrow house costs more per square foot than a wide one, so if you have room for 10 ft, our 10 ft-wide walk-in greenhouse starts at $1,489 and gives you more floor. What you are paying for here is a house that fits where the wide ones cannot. Against the premium hobby lines built on a lighter alloy frame, which typically open near $2,400, the galvanized steel frame is still the reason this sits where it does.\u003c\/p\u003e\n\u003ch3\u003e4 mm or 6 mm twinwall — how to choose\u003c\/h3\u003e\n\u003cp\u003eBoth thicknesses are the same UV-protected twinwall polycarbonate —\ntwin-wall, if you have seen it spelled that way. Two sheets are bonded over a\nsealed hollow channel, and the air trapped in that channel is the insulation.\nThat is why a polycarbonate greenhouse holds heat a single pane of glass gives\nstraight back, and why the light arrives diffused instead of laying a hot stripe\nacross your seedlings. Choosing between the two is a climate question, not a\nquality one.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4 mm\u003c\/strong\u003e — the right panel for mild and temperate\nzones and for spring-to-fall growing.

The upgrade costs a\nfew hundred dollars on a short house and more on a long one; panel area is what\nyou are paying for.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThe short version:\u003c\/strong\u003e if you intend to grow past the first hard\nfrost, buy the 6 mm. If the house shuts down in November, 4 mm is the\nhonest answer and the difference is better spent on the next length up.\u003c\/p\u003e\n\u003ch3\u003eGround, permits and assembly\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoundation:\u003c\/strong\u003e level, well-drained ground is the whole\nrequirement.
