Read quite a bit about gardening, and I'm looking for some clarification.

1 - Intercrossing - is this determined by what is next to your seed when you plant it, or harvest, somewhere in between, or can a combination?

2 - Shroud Soil - used some of this, and got 9 seeds from a plant. Is this possible with all seeds, or just the low/mid level ones?

3 - Grow times - I know the big excel sheet has grow times, but there's a lot of variance for the same type of seed. Is there a place with grow times listed by seed type?
