TENT GROWERS* how are you draining run off in a trellised flower tent

Oh, and you guys could always hook up marine bilge pumps to a cheap 12v power pack, and suck the water out of the catchment trays.

Someone posted this one awhile back, but you could make your own setup with a pump, plastic bin, and mesh. : https://www.amazon.com/SearQing-Mar...hvlocphy=&hvtargid=pla-4583863996256699&psc=1

That was me and it was the greatest move I've ever made.
 
To the OP... I have 20ft trays in my main room. I know you said you didn't want to suck it up, but this may be your best option is a ShopVac Pump Series. It has a dump valve that you can hook a standard garden hose to and never have to take the top off to dump. I only take the top of mine off every grow cycle to clean it. I'll occasionally suck up some bleach to keep things clean.
Great info I appreciate it
 
You can get a manual liquid transfer pump for $12 on Amazon. The battery ones are fine too, just less reliable and use batteries like crazy.

I got one of those on Amazon when it was on sale for $23 a couple of weeks ago, but haven't set it up yet as I'm waiting for my runoff trays to come in still. Looking forward to getting it dialed in.
 
I use a tray to catch the run off raised at one end and a piece of capillary matt at the low end to empty the run off into the jug, during veg they're on the floor so I use the syringe to feed them and empty the run off from the tray.

One time I did a whole coco grow and sucked all the runoff trays off with a water blaster from the dollar store. Also could feed pots with in way in the back.
