Upside Down Irrigation Question

I have one long plot of turf that I need to get irrigated. It is under a metal structure frame, and I want to have sprinkler heads at the top of the structure down the middle facing downwards (almost like what you see in office buildings or hotel rooms) that can spray the width of the structure (about 10' radius reach). The structure is 92' long and 20.5 feet wide.

Will I need some sort of pressure regulator tapping the water source so I don't blow out the heads? Any recommendations on what heads to buy/where to buy them?

Nozzles on normal irrigation sprinkler heads are designed to be upright so the water arcs up as it exits. If you turn them upside down, the spray will point down, and you will not get an even spray pattern, though someone here might be familiar with nozzles designed for greenhouse use. That, or you can suspend the pipe low enough to use the nozzles upright.

That's the problem I thought about as well. I guess I'm looking for more of a greenhouse style head. Hopefully someone with some knowledge of that chimes in. Thanks for the input.

Correct, you're looking for Greenhouse specific irrigation. The stuff we talk about here is primarily installed underground. Here's a site with product line (googled greenhouse irrigation) http://www.greenhousemegastore.com/c...ation-watering .

I don't know anything about greenhouse irrigation but with your question regarding the pressure regulation, you'd have to know how much pressure you have from the source and how much is necessary to run your system, how many gallons per minute you need, etc. For example, most irrigation we deal with runs at 40psi and we calculate how many gpm we need and design irrigation piping system and head layout from there.

Maybe visiting another greenhouse (pretend you're a customer) and see what they are doing?

You might conduct some tests on standard spray nozzles installed upside-down at your ceiling height. 8-foot radius would be my first try. It might be that the nozzles would have to be a foot or so lower than the peak height.

Look at inverted mini wobblers. We have these in a few of our propagation houses. Work great. Depending on what you plan on doing in there, you might want to have a misting system if it's something you're going to be keeping constantly moist like seedlings or cuttings.

Center pivot type nozzles would probably work good for this.
Rotator story.
