Yes, you can use pretty much anything to do this job, but I wanted to make it simple to judge the depth and space needed when potting up seedlings. 36mm at the top.
I have included a taller version that makes it a little bit easier for deeper planting.
I hope this helps. Please leave a like if it does, and post any makes or remixes.
