At the garden center where I work sellimg christmas trees right now, we have a new type of hydroponic crop growing system to sell. This one is vetical: it doesnt need a lot of room, and can be moved anywhere without disturbing the crops. It is totally self-contained and easy to maintain. Every household could have one. The plants grow in rockwool on the sides, and the lightbulbs are vertical, allowing no energy loss. We tried it with basil and dill, and I made very deliciouse pesto with the trimings yesterday. I am told it could produce 6 lbs of delicious greenery every 60 days. At about 3500 candian a unit, I know what I want for christmas. Homegrown greens all year round.
