Greetings. I'm currently working on a small terrarium with a few plants (Cephalotus, Drosera, and a Mexican Pinguicula). However, I've been having difficulty finding the exact pots I need. I need something somewhat tall for the long root system of the Cephalotus, but I can't find the exact pots I need. However, I purchased some clear drinking cups at Walmart which are the exact size I need. The only problem is that they are transparent unlike a traditional growing container.
Are there any cons to this? (ex: light affecting root systems, etc?)
