Right, because obviously your Google search beats my actual eyeballs.

Took me two weekends and about $200 in materials for my 8x10 shed, but I dug down four inches, tamped the dirt flat, spread a layer of crusher dust, and then leveled six concrete deck blocks right on top. That was six years ago and the floor is still dead level, no sagging, no rot on the bottom edge. Laying a few courses of paver base on top of the gravel just gives you a rock solid surface that drains water away from the framing.

Bet the lower light stress lets roots grab soil before the sun hits them hard.

Lowering my amps by 10 on 3/4 inch made a night and day difference.

Oh man, I gotta say though - soap isn't actually the enemy here lol. Modern dish soap is totally fine for seasoned cast iron, it's the lye in old school soap that was bad. Your grandma's pan probably just needed a good scrub and a fresh season after that tomato sauce incident. Still sucks that someone treated it like a regular pan though, I'd be mad too.
