Looks awesome. When you say sheets, what material, specifically, are you talking about? Plexiglass, or something else?
I think it’s just polycarbonate, the branded stuff where I am is called laserlite.
Just the sheets you find at the hardware shop for decks and outdoor areas.

I've collected like 15-20 free trampolines, from 12-15ft diameter. You get 2 full arches out of every frame ( I go a max of 8-10ft between ribs, fence top rail pipes work good as connectors), and they make the best temporary hoop houses I know of. Already have the fittings built right in where the legs went too, just add pipe! They even hold up with 2-3 ft of snow on top! I've raised them an extra few ft with side poles, for more ceiling height. I make carports and all kinds of structures out of them. You couls even do quarter arches of the frame, and make a lean-to like shelter right up against a house. Can't beat free pre bent galvanized arches. Some of the trampolines are super high quality, with thick steel and solid re-enforced connections! Anyway...

Being on your porch, I'm guessing whatever lightweight portable canopy like deal you use might end up on the neighbors roof, especially it you don't cinch it down good somehow during storms. Good luck!

I built this. Lattice to keep unwanted critters out , deer and rabbits here will rip you off quick. This is the modified version the first didn’t have enough pitch on the roof. If the rain doesn’t drain fast enough it can cause sagging on your roof and sagging leads to pools which lead to collapses.i have a door thats lock-able(state law) to get inside. This year im gonna wrap the lattice with screen to keep the motherfucking moths out lol. When I built it i was just kind of fucking around and cut some corners and shit,and if i do it over i will definitely go at it more like im building a permanent structure. It worked perfectly except for the moths/caterpillars. I’ve been using box store 6mil clear plastic but this year I ordered real 6mil greenhouse sheeting for the roof.it’s approximately 17’x 20’.

Depends on how big your plants are. I’ve used mine for 3 years now.

I bought greenhouse plastic off of Amazon ( once you know how much you want, you can order any size)

10’ sections of 1-11/2” schedule 40 pvc. I used 2 per hoop, had 3 hoops, so 6 sticks.

6 three foot pieces of 1/2” rebar I hammer into the ground and the slide pvc over the rebar.

I connect the three hoops together with 1x4 and secure them around each hoop using plumbers tape (I tried using rope the first year and it wasn’t strong enough)

find the middle of your greenhouse plastic and sandwich the plastic between two 1x4 the length of your hoop house. Slide it up on top and secure to the underside of the pvc with plumbers tape.

remember to overlap by a few feet in the direct the rain generally falls from. In my case it’s always from the west, so I leave plenty of room in that direction.
