  1. Folgers coffee cans from Costco are nearly perfect Kratky containers. They’re plastic, food grade, with a snap on lid and are about 1 gallon, which is enough to last about 6 weeks from my experience. That is the same amount of time for a head of romaine to reach a good size for harvest. Just drill the hole for a net cup in the lid and you’re good to go. They even have a built in handle. My only complaint about them is they can be difficult to get really clean on the inside after use since they have embossed letters, etc.
