Green house suggestions

[Artstone]

suggestion; I used to work in the nursery industry. A metal frame greenhouse kit with poly-carbonate panels,. they come in different sizes. Put a screw in ground anchor in all corners and one in middle of each wall, for one about 6x6. I would add angle braces in walls for added strength.18"-24" exhaust fan on thermostat, I'm using ac filters in the door for air flow. A little ele. work for lights etc. A basic DIY project. Note; 4x6 starting at $175 on TEMU

Is TEMU a legitimate company, I’ve heard lots of talk about scams , but don’t know if those sources are correct
