Thought I would add a video of my setup. It's made a world of difference, but I will be tinkering with it as the season goes along, I'm sure.

The last question I have (for now Very Happy ) may be the deal maker for which system to use: Can I use a rain barrel or is there not enough pressure? My barrel will only be about 6" above the top of the boxes, but I could safely raise it up at least 12" higher.

I've read on Uni of Fla agricultural web site that you get 1# of pressure for every 12" height. I am guessing that for mini sprayers, you would need between 8-15# of pressure. For spot drips though I would think 1-2# would be OK.

Interesting thought.

I thought you needed just over 2 feet to create 1 lb of pressure?

1 cubic foot of water weighs 62 lbs. 62 / 144 sq. inches = .43. So 1 foot = .43 pounds per square inch.

1 psi / .43 = 2.3 (need 2.3 feet to create 1 lb of pressure).



Also keep in mind that the friction of the hose will cause the water pressure to drop (twists, turns, elbows, etc. will also contribute to pressure loss).

Good catch. My memory is faulty sometimes.

Irrigation


A popular option is using the water to irrigate lawns and gardens.
You can install a pump or use gravity to feed hoses. Another option is
to just hand water. Make sure you set up your tanks for easy access to
spigots, outlets, or lids.


For gravity-fed irrigation: every 2 ½ feet of elevation of the water
source above the water outlet (e.g. the elevation of the tank versus
the elevation of the garden) will create one pound of pressure. Keep in
mind that friction in the pipe or hose will reduce water pressure.


Contact your plumbing or building department before connecting a
pump, plumbing, or irrigation lines to see if you will need backflow
protection for your potable water line. Do not connect your rain barrel
or cistern to your in-home plumbing due to the risk of contaminating
potable water.

Wow elliephant, looks great! That's the cool part of this type of system, you can add drippers here and there if your inline tubing isn't covering the whole area.

My grandparents lived in McAllen, so growing up, we were always heading down there from San Antonio.

Good luck with your garden...it looks super!

But before I forgo the usual gift of beer, can any of you tell me more about setting it up?


  • How do you position the lines within your squares?
I run my lines along the grid(they could theoretically replace the grid, but I choose to keep a grid also).


  • trukrebew wrote:Do you cut through the center of 1 square or double back?
I have a main line running at the back of the bed, with 1 smaller line running from the back to the front. If I were installing this in a 4x4 bed it would look like an elongated "E" with the up and down line being the main line.


  • trukrebew wrote:How does it work to cover all 9 or 16 plants in 1 square?
Drip irrigation soaks into the MM and spreads about 12" from the emitter. Depending on the emitter size and spacing, you can cover quite a bit of area with a single emitter(normal spacing is 1 emitter every 12", I'd stick with that and just adjust the timer as needed).


  • trukrebew wrote:How do you get it across the aisle, from one box to another?

Run the main lines(1/2" diameter or larger pipe) along the back, inside of the beds and use 90 degree elbows to make it look good(it will kink if you try to bend it). That or make your beds longer than 4' so it's easier to install the drip irrigation(this is what I did).

As a side note, I'd get individual emitters that can be taken apart if they need to be cleaned instead of buying the drip line with emitters inside that line. I'm not sure on the price difference, but it will take longer to set up. You can't really fix or replace a bad emitter that's inside the line without cutting out sections and splicing it back together.

I see the wisdom in this. I already had to add in a small line with a separate emitter where one of the emitters in the line wasn't working.

I did splurge on a timer, which was around $30, but that too is worth it. They have tons of videos on mrlandscaper.com showing you how to do it. It's really easy.

My husband was pretty impressed that I didn't ask for his help even once. It is soooo worth it, and my plants starting looking better within a week. We have already gotten into the 90 degree temps, and I have it set to water every day in the morning.

I saw a demo of this product at Lowes Saturday. Looks very simple and relatively inexpensive. Spoke with the vender demonstrator and found out the product is manufactured about 4 miles from my house.

Cool ! Wish I had seen a demo before doing it. May have gotten some tips on layout...

The jets covered about 4 to 15 inches (1 to 2 sq feet) of space depending on which nozzle. The 360 seemed to cover about 1 foot by 1 foot area. The drip nozzles covered much less. The web site did have a few videos.

I have all this stuff in my garage and waited too long to install it. Now there is too much plant root material for the installation to be practical now. I just plain procrastinated too long!

I have this tall brass sprinkler with two counter rotating concentric circles for emitters in the center of the overall square formed by all the beds. I truly meant for the sprinkler to be temporary but, knock on wood, it really has been working fine

picture of one like it - not mine

after my corn gets done I hope to start getting the drip stuff installed. I love the mister landscaper/mister stuff. It has always worked for me.

Re: Best thing I ever did for my SFG

Post  Coelli on 5/14/2012, 3:29 pm

This weekend we built two grids for the two 4x4 beds. We haven't finished building the line that will connect them, but we were able to test them out one at a time with a hose. We drilled 3, 3/32" holes in each section of pipe about 3" apart.

We originally built them with capped ends, like this: http://squarefoot.creatingforum.com/t11301-pvc-watering-grid, but after testing it out, I am concerned that water is not reaching the corners of the bed. Although water was draining out from the box freely, the corners were still bone-dry. To get around this I think we could add a single elbow and one more length of pipe to each corner so the corner squares will at least get watered on 3 sides.

We also found that water pressure is super-dependent on how level the grid is. Smile I think this will be a challenge (the grid lies on the dirt, and the holes for the water are on the top of the pipe.

We'll be running a 1/2" drip irrigation tube off the input so I can run 1/4" tubing to my various other pots and tubs. I'm very excited to be able to turn it all on in one spot!

My answer is simply build one. I am enjoying it so much. I am looking at doing an irrigation system but not until the fall. I will build another SFG at my camp for fall crops.

Post  Coelli on 5/24/2012, 12:31 pm

I should follow up - after some frustration with not being able to get even pressure with the PVC grid, we re-did it with less and smaller holes. This helped with the pressure but the corners of the box still remained dry and I could see there would be issues with tiny seeds (like carrots) in the centers of the squares.

So we scrapped the whole thing and put in soaker tubing instead. You don't get the nice grid effect, but it seems to be much better at evenly watering the entire bed without disturbing the soil.

We'll keep the PVC grids for the kids to play in on hot days. Smile

Auto overhead sprinkler system

Post  Nymiko on 11/16/2012, 4:09 pm

Hi, I just start my SFG in Oct and I was initially planning on adding drip irrigation to my box but after reading SFG, Mel said to just deal with the auto overhead sprinkler system that I have. Is it possible to have both an over head Plus a drip irrigation?

On a side note, Could someone please be so kind as to advise me in Zone 10a how long should my sprinkler be on for and how many days a week? it's going every other day and both weekend days right now for 20 mins at about 6:15am. I direct sowed my bed so while i was waiting on sprouts I've been implementing some garden hose watering everyday. (mel said you can't over water.... Right? but i'm worried the rest of my garden is getting too much water. LOL I don't know how to test which zone valve is which so I have them all going on the same setting. thinking
