Considerable research has been conducted on the "willow rooting cofactor" that is present in willow stems. When extracted, it has facilitated good rooting in other species. See PIPPS 35:509-518. Unfortunately,
it does not perform on a consistent basis.

The only unit here that allows 10 seconds of mist every 10 minutes is the DIG5006-IP. It's expensive but quite versatile if you don't want to be tied to your operation all summer long because of watering. I had little in pots last summer because I was pretty well sold out early but it would have been a watering problem with the drought that we had and the excessive heat so I'm going to set up a second circuit to control early morning irrigation before misting begins. I'll put a y-valve on the tap and run a second water line with a solenoid valve in it to my pots. I don't want to water from overhead because it's not that efficient and I pay for water. I'll use emitter tubing which unlike a soaker hose waters evenly from beginning to end. 100 feet of 1/2" tubing is $35 Plus shipping and tax which is OK. The T and elbow joints are cheap as well. And the flow rate is .9 gal/hour. The only downside that I can see right now (and I'm sure that there will be more as I start to install) is the web of tubing will make navigation interesting. I'm going to have to fiddle with a layout design. Long rows would allow easy access without having to struggle with hose.

Do you have a link to what you use? Do you the same pressure at the end of the line that you do at the beginning of the line?
This is what I was thinking of using - http://store.rainbird.com/drip-low-volume/et63918-100-emitter-tubing-100-ft-coil.html
