This is a pretty basic question (so beginners section is right then), but I've just bought 8 3x3x2.5 rockwool cubes for starting my plants. A couple of questions.

.1. I only grow in soil, and will be for this grow to. With the hole in the rockwool being 1" is it ok to cover the hole in soil and then let it grow (this should be ok, but trying to confirm things).

.2. These are pretty big cubes, and I intend to only grow my plants to about 14" mature. Will I need another pot to put them in, or should the cube do it completely.

.3. Feeding: When I water these cubes, will they fall apart, and how much should I water them? This is the main question I want answered please.

Thanks for any feedback.
