I wonder how lambsbread to a different afghani would do.
Lambsbread X DLA16 ← a 100+ day Indica.
'68 lambsbread x herijuana ibl is also an option. I have both. Herijuana is a hybrid though. Something like Shiskaberry, BSHW or Snow Lotus may be more similar than a pure afghan.
Could go real deep and recreate lambsbread from the imported parents and then cross to an afghan landrace.
