I'll settle for good tomatoes year-round, minus the coke. I mean, sure, coke tomatoes would totally supercharge everyone's summer. But then the Big Dark of winter would suck so much more.
Do you have any concept of manic winter cleaning? Have some ceviche or tacos with salsa and get productive, clean the house with a toothbrush or write your novel and accompanying screen play during those long winter months.
S.A.D. no more, geek on tomatoes and get shit done.
As always, it would be simpler to use yeast... It's going to get wild when these yeast strains get into the illicit market and people are literally brewing up coke or morphine in their bathtub.
I have actually wondered why this isn't a thing. You can order a yeast 2.0 sample from a supplier and the relevant DNA strand from a DNA printing company, multiply the DNA and introduce it to the yeast and you're game.
I think it's the "introduce it to the yeast" part that's the hard part. But I can't imagine the types of precautions the people who already have a morphine producing yeast strain (yes some people already invented it) must take. The illicit value of that is like priceless.
