Vitavia Neptune 8x10 Greenhouse Toughened + Base
I absolutely love my 8x10 Growhouse. Especially since I have had on many occasions a chance to experience many other types of greenhouses in varied climates around the world. From California to Florida and Europe the Growhouse design, materials and simplicity of construction make it the best! On top of that I recently experienced so adverse weather in Spring and a large branch broke through the roof!! To my surprise the 3mm tempered glass didn't shatter despite the ridge board snapping clean in half!
