Rocket Seeds - Experiment Complete

Today was the final day of our Rocket Science experiment - we had to record the percentages of seedlings alive in each tray.  Our results indicate that 90% of the blue seeds are growing well, but only 72% of the red seeds are still alive.  Does this indicate that the red seeds were in Space?  Or could it be that seeds, which have been in Space, grow better and hence the blue seeds were in Space?  We are all waiting now to hear from the Royal Horticultural Society who will let us know their results in due course.
