My two (4SD x Chem DD) x Sour Jack that I call LDSC, LouDog Sour Chem have been great plants so far, one was first out of the shell and both have been healthy. I got two phenos, one tall and branchy with longer internodes and lower branches that have caught right up with the tops, and another that’s staying more columnar main tops with stringy lowers and much shorter. Here they are at Day 31 of flowering in 15 gallons of my recycled dirt and ProMix HP-CC/pumice mix:
