Pretty badass...he did this backcross open pollination to open up pheno expressions while holding the genetics to their true lineage.
The One: 1976 Highland Thai x 1971 Kandahar Afghani. A balanced yet potent F1 landrace hybrid from 1984. Floral/perfume, fruity, incense, skunky/musky flavors on large, dense, resinous flowers. The euphoric Thai/sativa affect hits first with the body numbing afghani affect settling in after. Strong stemmed structure with excellent branching and stretch. Finishes in 8-9 weeks but can be allowed to mature until ~12 weeks for a more potent 'body high'. I like 10-11 weeks personally.
The One x Velvet Rush (TOVR): Velvet Rush is a similar cross as T.O. From the same era - Highland Blue Thai x Afghani #1 - but is extremely Thai dominant in every respect. Having been crossed with TO you end up with extremely vigorous, fast growing plants with the dense, resinous flowers of TO and an enhanced thai/sativa affect from the VR. I selected 4 males for this open pollination and the intent was two-fold:
1. By using the same males to hybridize all the females I create a solid genetic base to easily select plants that are similar to the respective mother for future backcrossing and isolating unique expressions.
2. Males were selected ranging from pure TO dominant, 50/50, and slightly VR dominant. This way we maintain the genetic diversity of the various landrace expressions to pursue within each individual cross and find amazing new hybrids.
