Drip Irrigation help

[Dab Strudel]

Do you feel like the following manifold would suit me as far as feeding only water evenly, using the ball valves to control the pressure. I am going to be gravity feeding from a bladder about 300 feet away down a little slope the whole way.

I am going to have 20 plants (hopefully), 3 rows 7,6,7 down a 50' GH in raised beds (gophers, dry clay, last min)

Are the sizes of the pipes usable or too big? the slope is 90% of the 300 feet and the ground of the bladder is about 12 feet higher in elevation than the floor of the GH.

I plan on using drip hoses at the ends of the PVC, the point of the PVC is to be sure I am getting the most even watering that I can. How long of a drip hose do I need, diameter, and holes per foot to water plants using about 22 cuft (.82 yards) of soil per plant (which will be 3 feet tall when planting).

Should I separate my plants inside the raised bed or would it work without? worrying about root competition considering ive been told id need about a yard of soil to start now and finish the year with water only (amend soil)

Thank you all, look forward to all feedback

Lots of problems here. Off the top of my head, 1ft of rise equals about .4psi. So 12 feet up will only give you about 5 psi.....

All you questions should be based off the system you are using. What company emitters are you using? What are their specks?

Also, I have worked on commercial systems, and many personal systems. That diagram doesn't really address what's at hand here. The figures you need to know is the PSI, and volume of the main water line coming in first and foremost. Then you need to pick a drip system that you are going to use, and figure out the specks they want, then design your system to those specs.

Check out Dripworks.com

On that site they have a couple options, the one I recommend for beds less than 25' long are 1/4" drip lines with 9" on center emitters. The main line is where you will need to know psi and volume. My psi is over 70, with a gph of 580 and a 3/4" input. The 3/4 main line worked great for my system, and one zone controls up to 25 yards of soil.....or 480 liner ft of drip line.....check out the site, they have all the specs.

The more popular option growers on this site will speak of is the 1/2" pressure compensating drip line with emitters from that same site. Good luck.

I have since decided to go with smarties, unless I can build them for cheaper than 50 bucks per 4'x 4' x 24" deep... Ill have that math done tonight. In your experience with big plants, It would be better to make individual pots and space them out or build a long bed and space the plants out? Its late in the year so Im not acclimated to what would be usable right now. My guess would be individual pots since my bed wont be full (+/-20 plants in a 32x50)
I have not looked into specific systems, I have been fond of the type that have a manifold at the beginning of the drip line itself and only have a few emitters per line, but multiple lines per plant to promote evenness. hoping to have 1/2 gal per hr emitters and as many as it takes to water the plant... not sure how much the plant will drink by the time August hits, I dont have a lot of hands on experience with plants this big or outdoor, but the last week was over 100 degrees for the most part.
Ive seen a style of hose/emitters that lets you pierce the line where ever you want in order to drip where you would like. Im glad you have experience, would you be able to take the info I gave and point me to something that works well?

As far as the distance from the bladder, I figured the 2" in the beginning and tapering down would help with building the pressure, but again I have no real world exp in this. Do you suggest I use a little solar panel and a pump or change something else up?

I was hoping this would be a better take on a system vs the one in the OP. Clearly I have a gap in knowledge in water manipulation, would I need a more powerful pump on the line going to the plants with a weaker pump on the return line and a pressure regulator/limit valves on every ball valve?
