Drip Irrigation in my GH

[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

Looks good so far.
Everything hinges on the actual "head" or elevation of your tank and what emitters you are using.
You want to calculate how many gallons/minute you'll be using per zone. Make as many zones with whatever size pipe you need to reach the water requirements. You need to check pressure requirements of your emitters as well.
Gravity systems are tough, if you have hundreds of feet of head it should work. The bladder may help pressure. Booster pumps are sometimes used, most irrigation controllers have a circuit that can be used to control a pump via solenoid.
Good luck, automated irrigation is awesome.
