I didn't know there were so many ways to do a hydroponic grow. I'll have to look into which are the best for different types of plants, like what grows herbs better or vegetables better.

I'm somewhat inspired to set up a mist and drip that pumps water up to a top container to mist the roots of lettuces, then the unused water could drip from that basin into the herbs and the unused from that could collect in the lower basin to be pumped back up to the misters ...
