One week has gone by since my last post on the pepper experiment and tonight was the night to take a closer look and pot them up. All the seedling are healthy and have grown some, the seedlings grown in the DE still outpaced the seedlings in the Jiffy Mix. Besides being a bit taller, the leaves were noticeably larger and the stems thicker and like the tomatoes, the root mass was larger and more fibrous.
I'm still thinking the next time I do this I will start the seeds in 2" or 3" cells instead of the 1.5" cells I used this time. More space with less root competition could yield even better results.
