Dear Diane and Robert (Blame me because you are insane !!); I use the lazy method for soil mixes that are inclined to leak from all those pot holes. Coffee filters - Mr Coffee type, not Melitta. They fit 4 inch to gallon pots easily. Last for a year or more. Hardly hold any water and precut. Couldn't be easier. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
