Reddit mentions of SPL 50ml Conical Centrifuge Tube PP/HDPE, Sterile Non - pyrogenic, Non - cytotoxic, DNase/RNase - Free, Human DNA - Free (25 Tubes)

You're welcome -- glad I could help!

If you decide to go with large tubes, these are similar to the tubes I use, but there are cheaper options: 1, 2, 3, etc. It's important to look for tubes that are listed as either "sterile" or "autoclavable." I like the pre-sterilized packs because that's less work for me.

There are a lot of techniques out there, so sometimes it helps to list them out into categories with a few details underneath each. With a list like that, you can go through it all at a glance and decide what aligns with your budget, material availability, and level of effort/interest.

Let us know what you end up deciding to do and how it works out for you. I'm sure a lot of folks around here would like to see it!

Oh gotcha. There are a bunch of use videos and articles about yeast propagating and yeast ranching that you can watch to learn more. After I grow up the population of yeast, I divide it and refrigerate them in either 50 ml sterile centerfugale tubes or in 1 pint Mason jars depending on size. I buy the centerfugale tubes on Amazon. All in all, It's easier than it looks and is fun to experiment with. As long as you pay extra close attention to sanitation and sterilization you should be fine.
