I believe autos will be the future cultivar type of choice for large commercial cannabis cultivators, mainly because they will be able to rotate 3 or even 4 crops annually in warm and tropical climates, with very uniform plants all from soil-sown seed. Like soybeans.
Auto strains were created for far-northern lattitudes where summers were too short to finish photoperiodic strains. But they will see their biggest use in long-season areas, I predict.
Not that I like it. But the big seed companies, and mechanized large-scale farmers, love it. Terminal seed, no cloning operations, strict uniformity, 90 days whole crop seed-to-harvest regardless of season. Potency issues will be addressed in processing, via "blending" and extraction a la cigarettes. People will prefer consistency over potency in the end, and go with uniform brands because they can count on them to deliver a consistent taste and high. A "Marley's Choice" joint will be a Marley's Choice every time, like a Marlboro today.
