drip feed

[robertfaceplant]

Wondering if it is possible to use 55 gal res elevated off the ground to drip feed x number of plants. I understand that that higher the res the more pressure is built, but in what way can it work. -Vision is facing the res- my idea would be to have a slight degree of PVC coming off a spigot in two directions. One to the left and one to the right. It would almost look like an upside down V or a flattened lower case n. my thinking in this would be to build pressure so that the furthest feed line will have good pressure built in the line. From there puncture or drill evenly spaced out holes and tap into with a male peg, kind of like joining two air hoses. From the drip line add an emitter. Can this work and how would I get them to drip just the bare minimum? Are there emitters that drip less than a gal an hour? thanks and i cant wait to hear what has been done or what you guys think about the idea

Yes there are emitters that drip less than a gal an hour. http://www.irrigationdirect.com/dd-tc5 . I would not rely on gravity alone, unless you have a two story house and your garden in on the bottom story, and you put your res on the top story. If not I would just get a pump and put it on a timer.

Just wanted to second the quote!

pressure rises 1 pound per foot. drum up seven feet equals seven pounds pressure ... not enuf pressure.

you'd have to have the reservoir up 20 feet or so to get pressure approaching the pressure from a suburban kitchen tap.

cheers for alternate thinking tho'!

thanks for the responses this fast..it would be a limited connection to energy, trying to feed of the grid. pvc size would not increase or decrease pressure build up? to push 20 pots what size gph pump would you think? solar panel a possibility for a small pump?

For an elevated rez & self feeding check out the blumat thread .... its exactly that with ceramic water sensing cone that only feeds when the sensor dries out . checkem out

the link you posted does not want to pop up. but was able to delete to adrs. AWESOME! thank you.

for 5 gal buckets/bags which would you suggest?

this would be for a larger outdoor garden, that being said i am reading the link from 2009 when posted and have noticed its a chain setup. could they be set individually so that if a salt build up were to occur the remaining cones down the line would get fed? maybe a emitter manifold off the spigot?

this sites the shit!

Increasing the pvc will up your volume but not pressure but you could run a pvc drip manifold and hand drill some 1/8 in holes controlled by a ball valve off the tank, it should flow fine if not just drill next size up intill you reach desired water flow.

They are set up individually . they're set up like your idea of a drip system where you have a larger feed line with smaller spaghetti lines going to each emitter . for a 5 gallon you could use 2 per pot . that way you have an even spread .
the maxi's are for larger or deeper pots .

My link is working .... checked it on another computer . read that thread .... i know its long & it will take a couple days ... but everything you need to know is there & then some
its worth it ... believe me !!

i'll link it again ....bluemat auto watering by sunnydog

Seems like bluemats would be a bit pricey to run a large outdoor grow. I guess it depends on what he means by large.

For an outdoor/off the grid large grow, I would throw a rez way the hell up a hill.

Sat X RB- Thanks for the useful info on the pressure calculation, im going to write that down!

actually you get .43 psi per foot of water.

I tried about 20 different designs of elevation, pumped, air driven, etc watering systems. Blumats are about the best thing you can get next to hand watering. I used the starter set once but in order to do what I wanted I would have had to spend way to much on them so went back to hand watering.

I have tried to look for some tutorials for DIY Drip Feed. U guys got any suggestion for tutorials?

 

[ambertrich]

pinaloki, here are a couple links to get you started with some ideas for drip feed.

First is pico's tutorial on how to make a PVC dripper manifold:

https://www.icmag.com/ic/showthread.php?threadid=62654

Lots of info good info and tweeks in that whole thread.

Another that may help you is Hundred Gram Oz's thread on DTW in coco. Though he is using coco as a medium, I think there is lots of good info about running DTW drip feed in general.

Hope this helps in some way.

I do it in my out-door garden and it work Great. You have to use a special rain barrel soaker type hose. Use a {multi-set timer} and a solenoid valve to open and close- turn on and off the water just set-up your watering cycles. Here's a hose link http://www.rainbarrelsoakerhose.com/ make a circular hose around each plant. You can also get {non} pressure gravity emitters that you can get in 1/2 gal an hour on up, your choice. so yep it will work great with a little internet home-work. Jay

They also have timers http://rainbarrelsoakerhose.com/542timer.htm Jay
