Hi, Let me try and describe the entire system. It is not totaly installed yet. I've strted installing it but I still have a fair amount left. before this system I was watering once per week with a watering can. As you can probably imagine the plants did not like that. Particularly since the garden is located on a windy hill. I lost 50% of a large tomato yeild to cracking related problems as the result of uneven watering. A number of other crops were total failures and some like the corn did not have to much of a problem (not suprised given it is a c4 plant). Now for the system. On top of the hill, on a 1 ft Dirt mound and maybe cinder blocks is the large storage drum. A pvc bulkhead will be attached to this drum. Attached to the bullkehead is a 200 mesh y filter with a female hose adapter inlet and a male hose outlet. Attached to the filter is a 0 PSI hose end timer with a mesh filter on the inlet. Attached to the timer is a melanor automatic rain shutoff device. Attached to that is a 3/4" female hose adaptor with a 1/2" compression adaptor on the other end. Then there is a .700 OD 1/2" mainline running ~ 40ft across the top of the hill. There are three columns of terraced beds running paralel to the slope of the hill. The column closet to the start of the system has 4 5X8 beds. The middle column has 4 5X8 beds and the far column has three 5X8 beds. Each column will have a 1/2" mainline, attached to the 1/2" mailnie running across the hill with a tee connector, running one each side of th bed. The only exception will be the lowest bed in the farthest column which will only have a line on one side ( the far side) of the bed. Spaced 1ft apart running across the long side of each bed perpindicular to the slope of the hill will be 1/4" drip tubing with inline 1/2 gallon per hour emitters (20PSI). That should be about 40 Emitters per bed. With 11 beds that is 440 emitters. The fish pond (not sure how large exactly) is about a 10ft vertical drop from the top of the large tank. Since the drop is about the same for the bottom bed I calculated That I would have 4.3 PSI at those emitters and 2.58 at the top most emitters when the drums are full. when they are almost empty I'll have 2.58 PSI at the bottom beds and about .43 PSI at the top beds. On a sunny windy week with no rainfall at all I'm guessing the plants will need 2" of water since the normal recomendation it 1-2" of water per week. At .52 gallons of water per square foot with every inch of rain I calculated that over my 11 beds and 440 SQF that would be 228.8 Gallons of water a week per inch of rain. For 2" of rain that would be 457.6 gallons per week. Summary 440 SQF 11 Beds 10 FT from top of drum to pond surface 12" spacing between emitters 12" spacing between lines 440 emitters? 4.3 max PSI .43 Min PSI each tube is connected to two mainlines. Thanks for your help

I researched the youknowwhat out of this before I did anything. I'm thinking that's what has allowed such an easy time thus far. But thank you, your words made me feel quite good! FYI, incase anyone wants to know I filled the bed (8'x3'x14") with a yard of topsoil, 3 big ole' bags of organic compost and a big cube of peat it was mounded over the edge after the initial fill but a long light rain the next day or two allowed it to compact a bit to a perfect hight, almost to the top edge! Where can I get a good net that will not only keep pests out but also serve other duties garden coverings can be asked to perform? I'm not sure what I might need one to do but the prospect of buying multiple nests just sounds kinda silly to me.

My grandmother used salt in another way. She was the dutiful wife of a sweet minister who, without consulting her, purchased and planted many various fruit trees in their back yard. Two were in the way of the wash line, or maybe the story was they were berry trees and the birds would stain the wash. Anyhow, she wanted them gone but did not have the heart to point out to her sweet husband the bad planning. So every time she went into the back yard, she put several handfuls of salt into her apron pocket and liberally sprinkeled the root zone of these two trees with salt. Before long, they died of some unexplainable blight, and grandma had her wash line to her liking.

Update to the 6 & 10 Rule: It only applies when the 1/3 - 2/3 Rule of Cantilevering applies (1' can cantilever over 2' of cabinets). If your slab is 2 cm, you can have up to a 6" overhang without support. If your slab is 3 cm you can have up to a 10" overhang without support . If you are using a pony wall or cabinets with a depth of less than 2 times the depth of the overhang, then you need to provide support to equal at least 2/3 of the total depth of the countertop. .
