Since we put the fall garden in we have been experimenting with different dripper heads for the drip system we installed. We have finally found one that we like, it is the Jet sprayer. It puts out between 7-10 gallons per hour and pretty much covers a whole mineral tub for watering. The small drip head that puts out 1 gallon per hour just wasn't putting out the coverage needed. Now our only problem is that 1/4 inch line that we have it set on. Our set up is 20 mineral tubs set up under 20+ feet of cattle panel that is acting like a trellis. We have it set up in 2 separate sections, each section watering 10 tubs at a time. Since installing the new watering heads the 1/4 inch line is just not large enough to allow enough water flow to run 10 of the jet sprayer head. So we have decided to experiment with some low pressure PVC pipe, since there wont be constant pressure on it like a water line we can get away using this and by the way this is cheaper!
We found that you can drill a small hole into the PVC pipe and put the jet sprayer head directly into the hole. Instead of attaching this to the bottom of the trellis like we did the plastic drip tubing we will just set this right across the top of the tubs for great coverage. This will be a nice set up as when the fall garden is over we can put the drip system away out of the sun to make it last longer. We also want to do a set up for the strawberry raised beds, while perusing the sprinkler isle we found some pop up sprinklers that do rectangle patterns, they are a few dollars each and we would only need 4 but this would make watering so more efficient over hand watering or sprinklers that put water everywhere except where you want it!. With the water rate that the jet sprayers put on watering of 3 gallons per tub we would only have to water for approx 15 minutes! It takes me longer than that to hand water. I will post more on this when we get it up and going to let you know how well it works!
For everyone that doesn't know what a mineral tub is here is a few pictures of my mineral tub garden!
