Running 4x4 rock wool in 3x3 ebb table. Currently using jacks 321 and adding some of the fox farms stuff to it. I realize it’s a lot of cleaning air stones and perhaps buying new more often. Was using this combo in coco coir and results were pretty good. I’m ready to give it a shot but want feed back first.
Cheers!
How about pictures/description of your setup: if it’s a ‘waterfall’ you don’t need air stones.
Why would you do that? Jack’s has everything you need, including cal mag.
I’m not a fan of rock wool and would rather suggest using hydroton and a neoprene collar. I do use Rapid Rooters but the plant is out of those pretty quickly after transplant.
