The box comes with a canopy unit with a twist air vent. These seal well and perform as expected for starting seedlings.

Nice little kit. Decent quality for the money. Happy with purchase. Will buy more. I feel these are a good value and recommend them.

They're sturdy enough to be serviceable under moderate use. The are lightweight plastic, but with careful use you could use them for many seasons. Sturdy enough to reuse multiple times.

This is my first tent and i just love it. Great product and helpful staff. Happy with purchase.

Just get some seeds of your favorite plant and get at it. Got it yesterday, assembled today and just started planting. Overall, this has all you need to get started and know what you need next in your gardening adventure.
