how do i prep my rock wool for my seedlings?? ph and nute and such. Someone commented to water it does that mean soak it or what? Just what do I need to do to this stuff?
ph adjusted??? to what?Soak your rockwool cube in pH adjusted water for 1 hour or so. You can also buy conditioning solution from a hydroponic store that will adjust the pH of the rockwool. Then once you are ready to place the seedling in the rockwool, take the rockwool and give it 3 or 4 hard shakes to remove the excess water. Do not squeeze the rockwool because doing so will create air pockets which you do not want. As for nutrients, wait till your 2nd or 3rd set of leaves form.
the cubes will be in hydroton pebbles in net cups after seedlings are inserted and get continous water. i am doing bubbleponic setup. Is this right?The cubes should be soaked in water with a PH of 5.5 for an hour or so - then shake to remove most of the water.
DO NOT SQUEEZE THE CUBE TO GET WATER OUT.
The cube should remain slightly moist - not wet until roots grow out of cube.
To wet the cube after seedlings are started dip just the very bottom of the cube in water - do not keep the cube wet.
