for someone like me who has to deal with terribly hot and humid summers this would be perfect. i can't wait to hear the results of your design.Its my belief that the final design will feed and water the plant with 2 gallons of water and that supply be adequate to allow the plant to flourish for a 14 day period under conditons of 95 degree heat, single digit humidity and windy. Im getting closer. Illl be back.

I like the basic concept Robin, but what is the method of transfer from the 20 oz bottle to the leaching bottle?
On Saturday, i got out in the field and and attmepted the first real life installation of the latest design. Im not happy with the results as installation was too difficult and time consuming. I conducted the installations just before dawn and the ability to prepare everything was difficult while holding a small flashlight. I spent over 30 minutes per planting hole.
Practicality is as important as effieciency in my view. A system that requires one to carry lots of parts and then take forever to install them isn 't going to be practical for my growing methods. It was clear to me that because of the parts involved and the time required for the install, a grower could only complete a couple of installation per visit. I need to be able to carry the supplies to complete 4 installs per visit. Even at that pace, with my usual 40 plant grow, im going to have to make 10 trips.
Im back at the drawing board with new info. I believe I have found an effective method of providing moisture, I just need to find a way to make the installation of it quick and simple.
The design has to be practical, cheap, easy, light weight, and effective. Ill be back.
Increasing Soil Fertility Saves Water
Does crop growth equal water use? Most people would say this statement seems likely to be true.
Actually, faster-growing crops use much less soil moisture than slower-growing ones. As early as 1882 it was determined that less water is required to produce a pound of plant material when soil is fertilized than when it is not fertilized. One experiment required 1,100 pounds of water to grow 1 pound of dry matter on infertile soil, but only 575 pounds of water to produce a pound of dry matter on rich land. Perhaps the single most important thing a water-wise gardener can do is to increase the fertility of the soil, especially the subsoil.
Poor plant nutrition increases the water cost of every pound of dry matter produced.
Fertigation every two to four weeks is the best technique for maximizing yield while minimizing water use. I usually make my first fertigation late in June and continue periodically through early September. I use six or seven plastic 5-gallon "drip system" buckets, (see below) set one by each plant, and fill them all with a hose each time I work in the garden. Doing 12 or 14 plants each time I'm in the garden, it takes no special effort to rotate through them all more or less every three weeks.
To make a drip bucket, drill a 3/16-inch hole through the side of a 4-to-6-gallon plastic bucket about 1/4-inch up from the bottom, or in the bottom at the edge. The empty bucket is placed so that the fertilized water drains out close to the stem of a plant. It is then filled with liquid fertilizer solution. It takes 5 to 10 minutes for 5 gallons to pass through a small opening, and because of the slow flow rate, water penetrates deeply into the subsoil without wetting much of the surface. Each fertigation makes the plant grow very rapidly for two to three weeks, more I suspect as a result of improved nutrition than from added moisture. Exactly how and when to fertigate each species is explained in Chapter 5.
Organic gardeners may fertigate with combinations of fish emulsion and seaweed at the same dilution used for foliar spraying, or with compost/manure tea. Determining the correct strength to make compost tea is a matter of trial and error. I usually rely on weak Rapid-Gro mixed at half the recommended dilution. The strength of the fertilizer you need depends on how much and deeply you placed nutrition in the subsoil.
Here is what I am going to roll with. It is just a 1 gal jug with a half a pen tube siliconed through the bottom. Just like a giant aqua globe, the pen part goes int he ground. You can then cover the jug with a peice of camo net and some brush. I'm thinking this will give a plant 2 weeks of water or so during the summer. Along with water crystals and some local rain we should be good to go for decent sized plants...I will make a prototype tomorrow.
