OK, I have a client who has 30 plus greenhouses (which are pretty old) and I'm trying to find a solution to increasing humidity levels. There are already exhaust fans fitted up high at one end, and the air inlet comes up underneath, and thru a grill in the slab. Seeing as theres not much of a budget (love the recent economy ) the solution that I can almost see is as in the picture. Swampy pads in a box built over the intake, with a 100/200 litre tub and a pump dripping water thru the pads (well it's almost a swampy). To minimise wastage I was thinking of a gutter/tray to catch the runoff, and my problem is this..
Can it be done with only one pump? I want the runoff to feed back into the reservoir drum, but I can't raise the box to a level it'll just drain in. The pumps we were thinking of using are your submergeable/pond pump type.
Being a sparky (in australia) , I might be missing something every plumber knows, but if you don't ask, you'll never know!
Cheers
You can google "evaporative coolers" and get alot of how to pics and videos,
One of them might be what you're looking for ....
Do not attempt vast projects with
half vast experience and ideas.

I grew up on a farm. Lots of different types of greenhouses for different purposes. All of my neighbors had other types of set ups.
I guarantee that whatever you're trying to accomplish, it's already been figured out and is being done commercially. The equipment is probably available off the shelf with no on-site engineering required.
What is the goal? What are they growing? What humidity, temperature, etc. are you looking for?

They're mainly for a certain type of orchid (Phy_ _ ?) I never knew, but apparently they're hard to grow well.
Rather than a system, I was mainly wondering if there was some basic rule of plumbing that could come into play.. I figured the pump would suck air in with something as simple as a tee-off (one branch in main tank, other branch in 'drip/runoff tray').
More of a 'clever trick' I spose you'd say
