Top feed drip with Rockwool cubes, yay or nay?

I was wondering if you should have a top feed system with Rockwool cubes.

I got some clones that came in about 3" cubes and am running a Bubbleponics set up.

The plants are in one gallon netted baskets. The roots hang down with a/b nutrients slowly dripped over them and it has run the entire grow. But I'm using a CMH light... https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.epicgardening.com/cmh-grow-lights/&ved=2ahUKEwjHroTPktzZAhUIuVkKHZXzAXEQFjAAegQIBxAB&usg=AOvVaw06bT0BZn1nEVKbw-OpSNqr
What size Rockwool cubes do you use? Mine are the size that projectnfo has in his pic.

I thought they were drowning as I have been having some problems.

But I think it was due to the temperature of the water and the PH as well.

And does it make a difference what light you use? For the constant drip?

Yea, that's what I'm doing. But I have them in like 4" Rockwool cubes under the hydroton, so I didn't know if that would soak the Rockwool too mucb
No that sounds sufficient. If your pump is too strong or ur lines r too short may cause a rise in pressure or a flooding effect
