Justin121. I use the thin bamboo bar-b-cue skewers you can find at the 99 cents store. I've fond that chop sticks are pretty thick and make too big a hole. Get one growing sideways and you'll see what I mean. I generally try to go by what Cervantes says, "Poke a hole the size, diameter, of the seed and stick it in there pointy end down about as deep below the surface as the seed is tall." I hope I didn't misquote him and I haven't had a problem yet.
