We have a spot in our yard for some raised garden boxes for a vegetable garden. Any recommendations for how to build one or for premade ones? It's something I could likely do on my own but I also have plenty of other things to do in the yard as we're still in the process of finishing it. So I'm open to getting some premade ones or a kit to save time but I'd also rather not have to spend a ton of money. I'm sure that's the tradeoff though. Everything seems pretty expensive online.

I've also seen people using those metal water troughs for the boxes. Anyone have experience with those? It seems like they'd bake the roots up during the summer.
