Holes at the bottom of styrofoam cups?

Wow, who would've thought there'd be so many ways to poke holes in cups, lol.

I make vertical slices into the bottom edge, which cuts the bottom and about an inch up the sides.

I really like the methods of doing a whole stack at once. I might try that this year.

I use whatever is handy, usually a sharp pencil or more often a long 4 or 5 inch nail left over from some building project. I think there is also an old fork from a barbeque set that got used in the past.

I ended up getting 12 oz styrofoam cups, and made holes with a long metal shishkebab skewer.

Luckily, I discovered that 18 of them fit very nicely in one of the carrying trays (divided for square pots) - they fit tightly at the top, and thus are not tippy.

I use a soldering iron for making the holes (5 -6 cups in one single step). This way, it takes only some minutes to get 100 cups ready for the seedlings. clara

I just took the long shishkebab skewer, put the cups upside down on a padded surface, and did about 8 at once. Went very quickly.

And a nice bonus - the local nursery just gave me a bunch of carrying trays, and wouldn't even let me pay for them. Nice.
