7. Problems from this previous season…
Some brought in on genetics brought in state, some naturally in our environment.
Growing organically is DIFFICULT!
No pesticides labeled for cannabis- only 25B products.
We can continue this type of work on the plant populations that are being grown for the first time in new environments. The plants can then be fine tuned through further MAB selection.
