Select forPhenos expressing dominant Breathwork traits will be most expressive
Amplified phenoHunt for Afghani-leaning phenos — that heritage appears on both sides and will express most intensely
Amplified heritageAfghani landrace appears on BOTH parental lines — this strain expresses Afghani heritage with amplified intensity vs single-side crosses

The record · 3 sections

The sun does arise, And make happy the skies.

The merry bells ring To welcome the Spring.

The sky-lark and thrush, The birds of the bush, Sing louder around, To the bells' cheerful sound.

While our sports shall be seen On the Ecchoing Green. — Excerpt from The Ecchoing Green by William Blake.
