.. noticed this wasn't answered ?.. I would add the worms after unless you have plenty to spare, in case your mix is hot. In other words, this is recipe-dependant.. but better safe than sorry same time. Re: the cover crop, it is a good way to get endo myco fungi established early, potentially allowing you to avoid individual sprinklings later at each transplant, as they need roots to infect (in a good way).. once a main crop is introduced a cover crop becomes a companion crop, with inherent pro's and con's to this latter stage. You can also do water only with amazing results if Hy's regime is too much for you. Make your own compost and the expression may wow you. & in Hy's defense, he makes all his own stuff for very cheap. Practically no cost, really. Once you have stable ferments they can last if stored properly. For example, use a small mouth bottle for your labs and it can last nearly forever if it's made right.
