Plants keep dieing in rockwool cubes

[jakester]

Not to be ornery, but there is a reason not to germinate in rockwool. The root sometimes will push the seed out of the rockwool

I never germinate seeds in rockwool. I do use the towel method and then transfer them to soil. By the way I use tap water to germinate as I want the excess chlorine to be there to prevent molds and fungi. It has no effect on the beginning of the germination.

That's weird, I have never had a problem. I just crush the soaked mini-cube a little and place the seed sideways. Sometimes I tamp a few fibers over the opening...

They all go.
