Howzit bud, I have not used the netbow myself, but they seem to be quite a interesting and effective design,
With your choices you have made, you need to figure out the context and if things will work with your ideas, so I’m sure you going salts and plan on running them through the net bow, which I’m not sure if you can or cannot do, but for sake of getting through the explanation, let’s say it works in the beginning or the foreseeable future.
I think they are the right size for the pot, just the medium might be an issue , also not too sure though, all drippers are effective because they are deigned to moisten the surface area of a medium that is similar to that of soil/peat/coco , hydroton has big holes inbetween each pieces causing the water to fall to the bottom faster, and not getting the full surface of the pot moistened nicely if you get my drift. One issue I see there.
You’ve probably got a decent amount of hydroton there, which I recommend you still use, but only for the bottom 1/3 of the pots, then the rest you can fill with a coco/perlite or full coco buffered ready to go mix, whatever works best for the hydro guys at the moment, I even tried a peat soil and that did very well with salts.
This recommendation is inline with the fact that I’m sure you want to use the netbows
The the netbows need to be connected to a manifold, hydroponic have the best manifolds, I think it’s called a manifold bubbler for some reason, you can get a bucket or 5gal container, put a small water pump at the bottom, you want to have some holes in the pipe leading to the manifold to release pressure as I find there is always too much
The simply connect the water pump to a time, chuck a few net bows in a bucket and let it run to see how much water is coming out after a given time. You will need a digital timer, and set it accordingly, 5/7/10 minutes twice a day when plants are grown. In the begining don’t bother with it, small plants need love and care Goodluck
