It's Mission Hydroponics of course. I especially like their groovy van, complete with the Pomona wheel. The van is actually for sale for $2,000. Tempting, I know.
fyi, hydroponics is the latest craze for urban vegetable and fruit gardeners, so it's nice to see Pomona on the cutting edge.
I'm going to keep a look out for other businesses that incorporate the Pomona wheel logo on their storefront. Email me if you see one. Maybe I can make it a regular feature on the blog.
