There are so many options for clear pots, it’ll depend on your personal needs and budget. I’ve tried all kinds myself and I can link some of the things I ended up liking from Amazon:

Pots from Homenote I use both the 5.2 inch and 6.7 inch sizes, they’re very sturdy, drainage holes are good 4.5” pots from Hahood Orchid pots variety set These are nice quality, a little softer plastic so more flexible. The holes are big so you need to use a chunky bark medium (or sphagnum moss) because soil just pours out the sides when you water. Tall square pots This brand is out of stock but I’m sure there’s others. They’re great construction and a nice depth, I personally wish they were more transparent.

I also just small plastic “take out” containers with the lids for germinating corms and stuff, I bought a small pack from the Dollar Tree.

(Going through my old Amazon orders makes me realize how much $$ I’ve spent on this silly hobby. 😬)
