    i just put my seeds in rockwool cubes and wwas wondering how long (about) does it take before i see something sprout out the top? i know it can take anywhere from a day to a week for a seed to germ but about how long before i actuallt see something sprout through the rockwool? Also how often do you water them? i hear see how heavy they are when wet then when you check them and they feel lite then water them but i have them in a prop tray so i cant pick up the cube to see how heavy it is. should i just touch the top of the rockwool and if it seems dry water them?

    its not good to grow in rockw. they have no nutri. and dry ot quickly but if you must know it will be about 3 days till you see something sprout it not longer.

    Sorry,but i do disagree with you on that.Rockwool is a great way to start seeds.I condition my rockwool with europonic 24 hrs before i start my seeds.Its also good to soak your seeds in water the night before you put them in cubes.Once the seeds are in the cubes i put them in a starter tray with a dome and set them in the dark and you may wait 1-2 weeks pending on the seeds before they pop

    im not saying there not good for starting seeds but the rock wool has absolutly no nutri, so when they got to put in a bigger pot the rock wool will still be there so it will be a bad move if you ask me soils just easier for some people and rock wool and hydro ponics for others.
