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.

Good customer service and a good supplemental light. Works exactly the way it was described very satisfied would purchase again in the future. Looking forward to seeing how my plants react to it.

The photo i uploaded from the product video is the part thats missing. Had to use duck tape to secure it.
