Subsurface irrigation

Work in progress on the custom pvc lateral line irrigation system.

The sand is over 6 feet deep in some areas! I saw @frozencaveman and @anon16547145 outdoor grows. Same cream colored sand. They looked great! Beautiful sun grown plants.

I can’t wait.

I don’t have any sand at my grow

I’m mostly sand, drainage is amazing, only tip would be if using underground pipes to give yourself a vent to pressurize it with air after use to clear out remaining water, or you’ll be like me and have to dump first bucket that comes out.

I use amended soil

My holes I dig out the sand and add 1.5 bags of roots organic original, some dairy doo mixed with premixed dairy doo, and my miscellaneous powders. Realized you can grow monsters with little dirt, but i grow clones mostly always so no worry of a taproot

Hahaha, I bit on your style, dogs win at killing gophers right after me with a garden hose and a shovel, flood those rodents in a biblical way.

When I build out for clients I always install ball valves at the end of the lines to be able to flush the system.

Sounds dumb saying it but how does the ball valves help you flush the remaining water out? I have ball valves on all my ends, but everything’s gravity fed

But on the issue of subsurface irrigation, I’ve seen some cool osmosis systems that maintain a specific moisture content in substrates. I’ll try and dig up some links. No idea on cost.

This garden is for what? I like raised beds with hardware cloth below, I also like top watering as it draws fresh atmosphere into the substrate.

The easiest way to deal with gophers is too line your holes with 1/2 metal hardware cloth, those little bastards can borrow 6 get down so suggest lining the bottom as well. Your best bet for this is to make cage that you can set into the hole. Make sure it also comes up a foot out of the ground or they’ll still get in. This doesn’t help the subsurface irrigation project ideas of long runs of perf pipe, but you could dig trenches and line them with hardware cloth. Initial material cost goes up but you have a lot less obstacles to irrigation plans.

If the valves are at the low point, gravity will drain the lines for you


To high up

Ya you will need a pump to flush with them in that location

Will be doing that next grow then, sucks dumping 10 gallons at 4 locations

I’m needing pumping over a hill. My thoughts are is I can keep a prime from the peak of elevation is my storage tote. Plots are lower by 8-10 foot slope drop. My wish is a siphon of sorts. Until spring when the well is put in.
If not a pot pump for the tractor and many trips with totes.

Flushing was two thoughts. First was connect a line cap threaded with a hose connector. Hose to surface. I’m on sloping land
It will need pumped thru to flush. Thoughts were a manifold with controls .
My thinking on the pipe system is wick based. I won’t have water just laying in the pipe. I’m wanting to pull the roots deep in the cool sand. Particularly where the sand is the deepest. Had planned on using my good dirt from our other place on lined wire trenches seems my safest way.

Much a setup like @FrozenCaveMan and @anon16547145 grow which is freekin beautiful! Very clean and natural like 70s tasteful porn!
FCS and EG telling the truth I’ve sinned… I really zoomed in and eyeporked your pics. Love it. FCM first thing I noticed was the color of your soil…lol. Port Aransas beach sand is what we call it lol. Farmers around here swear by growing in it. Fruit trees and watermelons!

sandy and gravelly
