Also, a few questions not directly related to the title of the post...

I do not add ANY nutrients for the first TWO weeks of the seedlings life cycle, right?
Would it be better to root plants directly into hydroton, or to use rockwool cubes?
Should the PH of my nutrient solution once done mixing be around 5.8? ((add PH-Down if necessary?))

Also, received Cal-Mag In the mail as well

When Do I know when to use the cal-mag? Every other watering? And should I just follow the instructions on the bottle... or is there a preference of how much Cal-Mag should be used for this particular type of garden?


So many questions as this grow is about to begin....
