There’s a hydroponics supply store near my house, but I’ve never been in there because I always think of illegal substances when I think of in-home hydroponics systems. These planter boxes from Modern Sprout take hydroponics out of the musty basements and put them on your windowsill. They may look like simple wooden boxes, but they have a system for growing three plants per box without requiring any dirt. You can grow vegetables, herbs, or even flowers in these boxes. They are available in three finishes (weathered gray, chalkboard, glossy white, and reclaimed wood) and with a choice of plug-in power or solar power. Modern Sprout started out life as a successfully-funded Kickstarter project, and they are now offering their planters to the general public on a pre-sale basis. (Shipping is expected in mid-September.) A plug-in box is $129 for weathered gray, chalkboard, or white; reclaimed wood is $159. Solar boxes are $219 or $249 for the same finish choices.
