Fortunately, when they got enough of the ingredients, they could easily experiment on the optimal conditions. They soon zoned in on the ideal formula, at least for the temperature and humidity of Alterra. They also had to consider the atmospheric composition, gravity, and even the soil properties.

Now, they had to test its performance in extreme temperatures. 

It happened that Tori had a thermostat so they could do it scientifically. They were experimenting with Bento, a Materials Engineer from the Eden government and his team.
