I got some window/railing boxes at a sale last year, and Walmart had a clearance sale on coconut fiber bottoms over the winter so I snatched those up for almost nothing.
In mid-May I filled them with dirt and planted out my surviving lettuce...and a few seeds. The seeds were lettuce, spinach, and radishes.
Those aren't radishes.
Actually I'm not sure what they are. Stunted broccoli? Kale? They even flowered before I realized it wasn't just some weird radishes (I've never grown them before).
Well, at least one lettuce made it.
