How big does the hole in the pot need to be?
My father gave me a glass vase that he had drilled to use as a semi hydro pot. It is really pretty but the hole is not as big as the ones in my plastic pots and there is only one of them. Is this going to be a problem? How big does the hole need to be? And if there is only one does that cause a problem with lack of air circulation?
