For our pumpkin patches, doing a drip line type deal made from mostly 1/2" schedule 40 PVC. No utilities at out property, so transporting water in IBC totes. Got the first one (smallest) done today and tested it out. Works pretty well, but place the pipe is just slightly out of level means too much or too little water in low/high spots. Will work on that.

This area I planted in rows. Just made a trench with rake, dropped seeds, and covered back over with rake. While that was real fast and 0 bending to plant, it left me not knowing where the seeds actually are. For the others, I started same way with the trench, then dropped the seeds, then covered each with a small scoop of topsoil. When I do those, I can drill the drip line to hit precisely at the base of the plant and not just random holes trying to soak whole row.

I think I would have come out a lot cheaper and possibly less work using drip line tubing or some type of tubing like PEX sold in a long roll. Joining a zillion 10' sections was slow work. But I figured once the season is over and there are pumpkin tendrils all over the line, this will be easier to reclaim and use again next year. Video to follow once it uploads. Any ideas how to do it more efficiently for next areas? I wanted to do smaller holes and have some micro bits but neither of my cordless drill chucks would clamp down on them. A #80 drill is smallest I have that I can use which is about 2 thou smaller than the .4mm bit I used today. But fewer holes or valves to only runs some lines at a time are probably going to be necessary for the longer runs.

Was really surprised at how well the Harbor Freight 12V DC water pump worked. No problem lifting from the tote and giving good pressure on this whole run. Before capping the ends of the runs I let it flow for about 5 min just to flush dirt and drill shavings out of the lines. All 4 had a lot of water pouring out at once. So that little pump really does a good job. We have fairly high water pressure at the house and this pump with a 100' of garden hose seems to give almost the same pressure. Haven't decided if I want to dedicate this trailer to nothing but a water hauler/watering system for the summer. I have a 100W solar kit so would be nice to set that up and run the pump off w/ 2 deep cycle batteries that instead of idling a vehicle the whole time. I tried first using a large garden tractor battery (around 400 CCA) but it killed it in half hour or less.

Get drip tubing from a irrigation supply house , it is cheap enough even if you have to throw it away .

Do you just drill holes in it like the pipe? Or do you have to buy lots of drip emitters and spend time putting each one in place?

The emitters are all ready there , just unroll and hook up to water . Here is a quick example

Amazon.com : Rain Bird T7-5S Drip Irrigation 1/2 (.7" OD) Blank Distribution Tubing, 5', Black : Garden & Outdoor

I must not be understanding what I'm seeing in that link. From watching the video there, it looks like you need to add several things to the line at each point you want water to come out? emitter, 1/4" line, stake, cap.

Half the cost per 100' run of that vs 1/2" PVC and not joining a zillion 10' sections to make a run looks nice.

Look around at different drip tubing . I dont use it often when I install sprinkler systems since little animals like to chew into it . But they have drip tubing with emitters molded in the tubing . 12 inches on center or 18 inches on center . All you have to do is hook up a supply and connect the pipe , then fold over the end and wire tie it .

RainBird also makes tubing that has little "nicks" in it every foot or so. Kind of like a soaker hose. That's what I've got running through my landscape beds at my house. Not sure how well it work with only gravity pressure though.

In southern califonria (bakersfield I-5 to San Francisco) we stopped in at a grape grove. THey used the 3/4" black coiled drip line but they had it elevated 18" off the ground. A long wire supported occcassional by T Posts and wire ties around the pipe and wire were all that was used for upport. They had just punched holes in the pipe, one every couple of feet and it worked like a charm. They had it elevated due to animal damage and did not use any of the spray heads because it wasn't worht they cost. Its a desert but the grapes seemed super happy. i am currently using sprinkler heads for our 40 tree orchard but plan to go to a drip system very soon.

I have a gravity drip system off an IBC. I elevated the tote about 5' and then have about 5' of fall to the line so there is enough head to make the system work. There are emitters made for the low pressures found in gravity systems. Generally I have to fiddle with them in spring and they're good for the rest of the year. The system is controlled by a 9v battery powered solenoid. That battery lasts all year.
