This video from Cooking Up a Story is right on target except for one thing and you probably know what it is. Of course, these salad bowls should be sub-irrigated planters (SIPs). They will be far more productive and built-in water reservoirs will significantly reduce the risk of drying out.
Small planters like these salad bowls are high risk for fatal desiccation. I see wilted plants in drain hole planters all over my neighborhood here in Brooklyn. There are wilted plants everywhere. It is a sorry sight in the heat of the summer.
The video reminds me of an old expression in my sales career and it is; “every disadvantage, an advantage”. It’s about flipping negatives into positives. There is a small business opportunity here created by the ultra conservative mindset of the garden center industry.
A SIP salad bowl business could be a home based business or one that is associated with an existing retail business such as a florist or hardware store. It would not take much of an investment to start a business like this. It could be a door-to-door business run by high school teenagers or college students.

It's great to see a business built on the exploitation of sub-irrigated planter (SIP) systems. Dick Larsen in Minneapolis was savvy enough to see the opportunity and seize on it.
