Large Greenhouse Irrigation

Hello everyone!

I have a 90 foot long by 20ft wide greenhouse. I want to setup a water irrigation system so I don't have to break my back watering over a 1000 gallons some days. I have a 1'' pump running through hose to a pvc tube where I insert in between the plants. They are flowering, and I can't get in there anymore so I am resorting to getting a 10ft long pvc pipe to flood the bed. Really taxing on the back. I have an idea of rigging a DIY water irrigation system using my pump. I want it if at all possible as cheap as I can get it. So I want to run 90ft hose between the rows which is 5. Then make holes in the hose, and at the end of the greenhouse just attach the pump hose feeding the water into already laid out irrigation system with cam locks. I would just simply detach, and connect for each hose running in between each row. I want to flood the bed as best, and evenly as possible. I run the water from a 608 gallon container where I mix my nutes, additives, etc. What do you think of this setup? I have a rough draft of what I think I could do included.

I would make it go from the main line from the pump to a 't' and then a large circles of you get the same pressure to all plants.

If that makes sense..I could draw a pic if you need ahah

A "T" that connects all hoses to a single line that the pump connects to eh. Sounds good, but would there be enough pressure to get water to all the lines attached evenly? The large circles has me a little confused I will admit haha. A picture would do wonders, thanks!

night time soaker hose trick is me

goes on 10am and off by a timer or temp switch ..about 2am

your hose perforating idea ..is sound

but unlike you in your pic I go from tank to pump then diy pvc, manifold

the soaker does both sides, but not down the side of the glass house

good luck

This would allow even pressure to all lines at the same time.

When you have one line that runs to all plants, the first plant will always get more water than than the last plant.

With a loop system, you are getting water to all plants evenly.

Sorry for my ghetto drawing

This would also work

I'm not sure if this is feasible as you mention you can't get in there but look into drip tape. It applies a constant amount of water at a slow rate as to not flood the plants.

Your chasing your tail. Irrigation goes in before their that big. Good luck and plan better next season.

Also you should run 1 line for no more then 30 plants.

I've used garden hoses with holes drilled in them for my peppers. You don't want more than about 25' to the hose, to keep the pressure closer to the same. It helps that the soil will be level in your beds. This time, with them already in bud, it would be hard to circle the plants. But that is what I would do for future grows.

I have a 365 gallon pot of above average intelligence that I buried two of the homemade soakers in about 6 inches deep. I put one in a tight circle right around the {tomato} plant, and one out closer to the edge of the pot. I used one of those Y splitters to control the water flow. Last fall was dry, so when I got the rate right, I just left it on unless we got a really big rain. {and I doubt it will be raining in your GH}
