My experiments this year are actually providing different results. I placed Butch T scorpions in 3 different mediums, (paper towel, organic soil mix, and jiffy pellets). All were placed in covered dome at 82F. Scorps would only germinate in Jiffys for me. Caribbean Reds and Manzano only emerged in the paper towel, and Bonda Ma Jacques like the organic soil and Jiffy pellets but not the paper towel. There's gotta be something more to this than just coincidence.
