We started with an f12 Abacus and did a selective breeding program; focusing on tight and tall with a high flower-to-plant ratio.
This is the perfect plant for a high-density grow, with CBD from 10-16%.
With very common industrial 15-15-15 fertilizer and high 8.2 PH (not ideal growing conditions) we were at 9.75% CBD-- including flower, leaves, and small stems harvested by combine.
Germination rate 63%, we harvested early, but you know what you're getting, start in a greenhouse or double seed.
These seeds were cleaned with a clipper cleaner and then a gravity table. Germ test data available.
Farm to Feeling
If your area allows regular seed, it's worth considering; never buy seed again or pull your male plants and save money.
Our farm's approach is that it is better to grow non-feminized plants and hire some hard-working farm hands, than to pay a premium upfront for feminized seed. So far it's worked for us!
Pull all the males or don't, either way you will be in a good position at harvest.
