plants were grown in same container from seed. do to space restrictions transplanting in a bigger container is an issue.i used earthgro top soil which next time i won't but mixed w perlite n blood n bone meal added to each container. lime.eventually toppped w worm castings n mixed that in as well.ph was high at first. i'll try a different mix next time or maybe b a lil more careful adding in the lime. added too much last time.
