We have now had our greenhouse for 16 months and absolutely love it! We run a glamping business on Vancouver Island and purchased it as a space for dining and relaxing for our guests when the weather is inclement. Our guests love it, we love it, and have hosted Christmas dinner for 10 people in it; had small musical performances; games nights; etc. We chose this as opposed to a geodesic dome, or any of the other trendy options for similar spaces because we knew if we ever had to switch gears in an emergency or change of lifestyle that we would have a first class growing space. We could not be happier with our decision, nd highly recommend both the product and the company.
Thank you for your fantastic review! It’s great to know how much you and your guests love the greenhouse and how versatile it has been for your space. 😊🌿
It completely transformed our gardening experience since 2022. Living in a region where summers regularly reach over 105°F and winters bring rain, wind, and frost, we needed a solution to extend our growing season. The greenhouse gave us exactly that—creating a comfy, warm environment that allows us to grow vegetables year-round, even on the most inclement days.
Inside our greenhouse, we’ve successfully grown everything from lettuce, arugula, cabbage, onions, and leeks to cucumbers, beans, chard, beets, butternut squash, radishes, tomatoes, melons, and peppers. The best part? Harvesting tomatoes in January and February! The soil stays healthy, retains moisture beautifully, and weeds are almost nonexistent.
We originally purchased the smaller model and were so impressed with the quality and the clear installation instructions (even in our 70s!) that we upgraded to a larger model the following year. Now we’re gardening with ease and enjoying fresh produce every season.
To make things even more efficient, we added an electrical outlet for lighting, air circulation, and heat if needed, along with an irrigation system that makes watering effortless. We also love that the greenhouse keeps deer out while still allowing bees to come in and pollinate.
Planta Greenhouses has truly exceeded our expectations, and we couldn’t be happier with the results.
I installed my first greenhouse in 2022 to support my collection of bonsai trees, which need protection through our harsh winters. The greenhouse has completely transformed my gardening experience. It allows me to perform complex procedures like root grafting and repotting earlier in the season and helps me stay on track with maintaining my 200 bonsai trees.
My experience purchasing from Planta was excellent from start to finish. The initial purchase, delivery, and build were smooth, and the company had clearly anticipated potential issues.
I’ve made a few upgrades to the greenhouse, including a gravel floor, multiple benches, and most recently, a light in the center of the dome so I can continue working late into the evening.
My favorite part of the greenhouse is the peace and tranquility it provides—knowing my trees are safe and thriving. I’m already planning to expand by adding onto my current greenhouse.
Assembly was relatively easy, using the manual and videos! Love the construction, very solid and durable. Recommend highly!
Hi Daniel,
Thank you for taking the time to share your feedback with us!
We were surprised how well engineered it is. It made the assembly simple. I can't wait to start my grow.
Best of luck with your grow – happy gardening! 🌱🏡
