If I was just recirculating, I wouldn't bother as much with regulating flow or putting loops in either. Just make sure they all get watered, really..

DTW is different though. Not only would I put in a looped manifold, I would finely tune each line by going around and measuring the exact amounts that each feed line puts out, for whatever the amount of time for the cycle. Like doing a compression test on an engine, I make sure all the lines are withing 5-10 percent of each other. It's tricky without putting a looped manifold to help equalize it. Messing with one throws off all the rest, etc..

If even one pot on one end of the row is receiving more nutrient solution, just to make sure all or some of the ones on the other end even get enough runoff, you'll be wasting a lot of water and nutes over time..

Yea that's what I'm finding is I'm going through alot of water and nutes.... Just gotta keep fiddling until it's good.

Just get an individual pump per plant.

Any particular brand name on these pumps?
And what are they called? What is it, a water pump, or what?

I found this: Submersible/Inline Water Pumps from Active Aqua. $13.00 sumpin'.

The only thing I don't like is how the inlet and outlet fittings are tapered, in a way that the lines could slip right off, when they should be barbed. I'm sure you could heat them up and jam a rod into it to flare it out though, and use little clamps. Maybe its not that big of deal though and not really enough pressure to worry about them leaking or popping off.. Still a good deal.

Wonder if they make a brushless motorized versions that cost a little more?

Its a low pressure system, not even a chance of them popping off

is it usually the diaphragm itself thats the failure?
I was looking at peristaltic(?) dosers but didnt like the flows and the thought of the tubing being flexed would be a fatigue type of problem.
the precision would be excellent for an automated nute mixer and PH controler though.

Huh?

Edit:

Just re read your post. Yeah a doser wouldn’t be ideal to feed plants multiple times a day.
