Thanx for your reply!
I was to anxious to wait for a response so when I got enough points I decided to go for the science 2, and I think, like you wrote, that it was the right decision!
Foodsupply is now 1692 and only a few minutes to new crop so I think I´ll make it this time (had to start over a couple of times although I play easy settings... )
Wasn´t sure about how many times I would be able to harvest thats why I was indesisive...

Great game, couldn´t wait to get home and see what had happened!
