It's almost July. I don't know where you live, but it is really late to be starting an outdoor crop. Most growers start their seeds in spring, just before last frost, and then have them put outdoors as small but healthy plants by the end of June. You may not have time to do a proper crop this year.

Also, Sour Diesels are pretty dense, adn if you grow in a damp area, make absolutely sure they get good breezes and morning sun.
