Another 24 inch wide seed starter bought at Lowes.
Avoid the smaller units since they won't hold much weight. The plastic rails holding the trays fold up with big plants.
I’ve got to get some 3 oz dixie cups. I saved some miniature muffin containers from the deli, and the 3 oz cups fit perfectly. I won’t start a lot of of stuff indoors, but may do some.
Looks like you are ready to start putting stuff out in the garden.
