I'll help MSM field some of these questions because he's busy as it gets in the garden.
1. RD#1 makeup - the exact crosses are proprietary, but this is basically an OG Kush IBL -5 different elite OGs crossed into each other to recombine all their genetic material.
2. What we offer:
A. Indica dominant line built around an Afghani IBL male
B. Sativa dominant line built around a Nevil's Wreck (Arcata Trainwreck [E-32 cut] x Neville's Haze) male
C. Elite OG line built around the Rare Dankness #1 male
Within those lines, we use a lot of the same moms for their unique flavors, fragrances, etc.
Let me know if I can answer any other questions (with the exception of anything regarding the Triangle cut - once again, those crosses are proprietary and MSMs keeping em under wraps)
