Regarding the rockwool cubes, I'm still new to this concept. What should I soak them in prior to my germination? I was hoping to plant them directly in the soil upon completion of the germination stage, so I'm still learning on this aspect. What would you suggest in terms of methodology?
soak the rockwool in properly pH'd water. for soil you want to aim for 6.3 (ideal) to 6.8. soak them 'til they stay at this pH. (the water you squeeze out i guess. never used rockwool personally. you might want to look into rapid rooters instead. why the rockwool anyway?

i just germ my beans in a bag with a wet paper towel. from there i pop them into soil.

i would seriously rethink the castings thing. 30% is probably still too high. also, keep in mind that once they are in you can't get them out! this with the rockwool might mess with your N levels too. don't forget about perlite. most recommend 2/3 soil to 1/3 perlite.
