First time growers, no I can't. I'd suggest soil or maybe coco or hempy.

I let my seeds germinate in a cup of water til they crack (ph around 7.0; ph isn't as important at this stage because there's basically no nutes in my tap water), then put them in rockwool and water them once a day or once every other day with maybe 1/8-1/6 of a cup of water; this whole time...

Hydroton* I usually leave my rockwool visible during sproutling stage because I'm top feeding, the water level is just high enough to wet the hydroton beneath it so the roots grow down once they can. After it grows a bit I cover up the rockwool with hydroton, cutting out the light and thus...

You have to top feed (aka water the cubes) until you get roots down into the wet hydroton area Dont put your cubes in water, make sure theyre an inch or two above, the bubbles will moisten the hydroton and promote downward root growth while you top feed the first week or so

I've never used those meters, I just go by feeding charts. I'm sure you can have a better idea of how much your plants are eating if you do use them though.

Good question, the answer is yes. Black paint, multiple coats. Roots hate light, light in hydroponics causes many problems including algae and other root bacterias.

I start my water level at an inch - an inch and a half below the rockwool, so that ends up being in my netpot. From there I lower it to encourage root growth and eventually raise it back up to the bottom of the net pot
