I built this mainly for flushing since I use tap water for that and I don't want to fill up 5 gallon buckets one at a time and pH adjust them all lol.

I used a folding cart I had sitting around and put a 30 gallon drum on it. I went ahead and put it on a couple cinder blocks since the cart is sorta easy to flip with the handle when there is little weight on it.

I used a 1100 GPH pump I had sitting around thru a 3/4" grommet with a barbed fitting and a shutoff valve with a hose connector. I coulda just been sloppy with the hose and just went up and out the barrel top but that's not my style. :lol:

I have a hose that's just long enough for my needs at 10 feet and a splitter that has two short 3 foot leads, save a drop water meters and watering wands. This way I can water two plants at once (this allows for the water to soak in instead of pausing periodically). The meters let me make sure I get the same amount of water to each plant.

I put a smaller 400 GPH pump I also had laying around in the barrel to circulate the water, I used the aeration attachment on the pump outlet. This is especially handy when titrating to pH the barrel.

I have a float valve on the drum that I can connect to a water supply, either my RO or tap. So I can roll it up and dock it to automatically fill. Then when I need it I simply roll it to the room I want to water, plug the outlet pump in, open the shutoff valve and go to town. I do have "docking ports" in each room to park it for a refill.

I may put a power strip on the carts handle and a 1/4" grommet on the air line but other than that I see it as complete. I will call it Little Blue. lol

I have a larger cart and a 55 gallon drum that I may put together and call Big Black lol. Will see if I need it, it wouldn't be easy to get through my light locks between rooms like the smaller cart/drum.

Images to follow in the next post from my phone.

How long do those water meters last for you?
I bought a half dozen or so a few years back and most didn't last the grow cycle, from amazon or hdepot I can't remember.

Hey ren how accurate do you think that water meter is? I thought about getting one and I probabaly still will since they are so cheap, but there wasnt very good reviews about them being too accurate.

I will give it a check but they seem accurate from the totals on the drum I did last night and the water delivered to the plants. I will fill a 5 gallon bucket and see what it says. For what I am doing it seems accurate enough to get within 0.1 gallons ish. Not sure how pressure effects it's readings, perhaps it has issues at higher flow rates?

I did it a couple more times and each time 5 gallons on the meter did the 5 gallon bucket to the proper level. So I am very happy with them for this application.
