i have to tell you that I originally thought about going that route until I saw one in person. if you are technically adept at all you can find enough info here and over the net to build a system yourself.

you will come away with a deeper knowledge about all aspects of growing when you're not spoon fed a system.

plus the cost that you save (figure saving 2/3 to 1/2 of their sale price) can go towards better seeds! :greenthumb:
