thanks everyone i have heard from my hydroponics guy that sunshine mix #4 is the top seller what i am doing is an outdoor grow in the summer and i will not be able to check on them more than maybe once a month as they will be about 100 miles away from where i live and am really looking for a soil that wont burn seedlings yet have a good amount on nitrogen and other good stuff without having to add a bunch of nutes, almost like the plant it and leave it alone technique. Do you guys think promix bx or sunshine mix no.4 mixed with 25% earthworm castings would be enough for the plants to live on throughout there life and be nice and healthy and decent yield?
