you answered your own question Aspen . lol
its all of those things you mentioned .
i could write a book to you explaining coco & how it works but it would take to long & all the info is here in the coco section . you have a basic idea because you've grown in coco before , you know its little quirks that are needed to grow in it & get good crops . if theres something you get stuck on or don't remember .... we're all here for you .
i see from further reading your doing coco instead of promix ....
Not going to take any chances with this run Dan... I may be stubborn some times but I want to get this right... So when the big dogs tell me I may fall short of my goal for some reason then I have to make adjustments. You guys have the practical experience and results I'm dying to have myself so I'm damn sure going to follow directions lol
