Earthbox planter, which already had some onions growing in it from seed I'd thrown in there in the spring. To this, I added oregano, chives, rosemary, and parsley, which I transplanted from the herb garden (just dug them up and popped them in - no fancy tricks involved!) I'm not using any supplemental light (other than the normal lights we use in the evening - the planter is in our kitchen), which means the herbs are already getting pretty leggy - but that's not a problem with herbs, since the leaves and stems are what you want to harvest anyway!
I should mention that last year I tried to grow tomatoes this way, with very poor results. Even with supplemental light, they grew very leggy, and never set any fruit. Oh, well. You live and learn!
I am a little disappointed that it's made of plastic, though - but I already have it, so I figured I should use it. If this works well, I will probably pick up some nice big terra cotta pots when they go on clearance next summer.
Meanwhile, I can't wait to enjoy garden-fresh pizza sauce in the middle of a snowy winter!
