For watering in a greenhouse, the Mist-King system is really not adequate.

Look at some of the micro watering heads available at “The Drip Store”. Stuff they sell, plus pvc pipe and a pump, and you’ll have a far more appropriate solution.

Sounds to me like you need to brainstorm awhile before purchasing anything. I was originally just answering your MistKing query. Kudos to Shady and Bill for going further than the original question.
