"I just wanted to says how impressed I am with your product. I bought one a year ago April. I live in Stevensville Fort Erie and we had the worst wind for almost 24 hours, gusts up to 120km and my greenhouse survived. Keep making this great product."

"I would definitely recommend this greenhouse. Not only does it look good in our backyard, but it is like having spring all year round. The orchids are flowering and also growing new orchids. I really can’t say enough about the greenhouse – and the staff that helped us with all our phone calls when we were putting it together."

"It is well worth it to invest in a planta greenhouse. It takes a bit of work to install the greenhouse as there are many parts but the end result is worth it. You end up with a beautiful greenhouse that can definitely withstand harsh weather! I love my planta greenhouse so far. We get lots of wind here and I was impressed by how well it holds up!"

"My favourite thing about my Planta Greenhouse is happening now, in January. When the sun shines on it, it reaches temperatures inside that are well above the outside temperature. I made room for a small rocking chair in the greenhouse, and I sit inside on a sunny day. It smells like soil, the air is slightly moist, sitting in my greenhouse just makes me smile."
