Get you a couple pieces of wood trim from your local hard ware and make you an A frame over what you’ve got. (2 pieces on each end and and 2 in the middle. Then use a clear shower curtain and cover.it will look like a tent and will hold your heat and humidity. You can hang your lights off of the A-frame.. probably cost less than $20
