it is an NFT system (sort of) I need to take more pictures of it functioning.

In the main tube there is a 1/2" pvc line with small holes in it that are squirting the bototm of the bucket. and then at the far end (away from the drain) the tube is open, with a raised opening that lets whatever other water come out and flow down the bottom of the channel.

I will take some pics and add them of the water flow tomorrow. I was thinking about lining the netpots with some screen I have on hand. It is a fiberglass window screen.

My plants are started in some STG starter cubes (I don't like some of the complaints about rockwool, like the fiberglass feeling from using it) which are supposed to be PH neutral and only mildly moisture whicking.

(I went ahead and took some pictures of the water system.)

The open end solved the problem I was having with small bits of the shavings of pvc and vinyl blocking the holes where the water comes out. the presure from the water having to go up the extra couple inches is high enough to let the holes shoot out some water.
