2 liter plastic bottles, a lot of

[luvinlife offthegrid]

What I use them for -watering things over an extended time where my hose will not reach. Most garden centers will offer plastic spikes that replace the caps of 2L bottles. The spikes have holes that let out water to the root zone. When that is saturated the watering stops. In fast draining soils it will start again as the water leaves the zone. I could write a short book on these as a watering device. Being cheap on my heavy clay, I just skip the spike, put a pin hole in the bottom, fill with water and cap tightly. Placed near a plant it will drip until there is a vacuum in the bottle then it stops. When it cools in the evening it will suck air back into the bottle to produce a slow leak the next day as it heats up. Sounds unlikely right ,so dont try it at home.~gd

I have only seen watering spikes at gardener's supply company. Anyone know of a less expensive source for these? I haven't seen them in home and garden centers where I live.

*edit* nevermind, I'll do this instead.
