rockwool ++

I just ordered my rockwool cubes. So I soak em in water and then germinate into them? then at what point do I put the cube into my waterfarm? When should my cube receive its first bit of fertilizer?

I have foxfarms grow big and bloom

when you can see roots coming out the sides than your plants are ready for transplant and start feeding them the same time.

Just feed them half or quater for the first week..

NOT counting the first two round leaves you will see, AFTER you see 4 tiny leaves, start 1/4 dose of recommended amount of nutrients.

Soak the cubes in pH balanced water for half a day, do not breathe the dust. AFTER soaking, remove the plastic covers.
