Last year, I planted peppers and cherry tomatoes in home made grow bags made from cat food bags. This year, I’m making more of the home made bags but I’ve bought two dozen commercial bags, also. These ollas are designed to fit into a tall, narrow space such as a grow bag. They’re about 5″ wide at the base, 16″ tall, and the tube is a little shy of 2″ inside diameter so a garden hose or watering can will easily fill it. They hold between 5 and 6 cups, not including the water they absorb. I’ve not yet decided on what style of lid they will use.
