Royal Victorian Hybrid Greenhouse by Janssens FAQ — Everything You Need to Know
What makes this a \"hybrid\" — and how is it different from your standard Royal Victorian?
It's a glazing hybrid, not a different frame. Our standard Royal Victorian (our best-selling greenhouse) is all 4mm tempered glass, walls and roof. The Hybrid keeps the same 17-gauge aluminum frame and glass sidewalls, but swaps in a 10mm twin-wall polycarbonate roof — which insulates better overhead and costs less to replace if a roof panel is ever damaged.
Which size is right for me?
Model 34 (150 sq ft) suits most backyard hobbyists. Model 36 (200 sq ft) adds a second sliding door and length without changing the width — a good middle ground. Model 46 (250 sq ft) is our largest, with extra width for raised beds down both sides and a center aisle.
What kind of foundation does it need?
A concrete strip foundation extending to your local frostline depth, with the greenhouse's integrated foundation frame anchoring into it — the same footing spec as our standard Royal Victorian line.
Does it come with a misting system?
Yes, a misting system is standard on every model, along with automatic temperature-responsive vent openers — no manual venting required on hot days.
What's the warranty?
