Tang Yue kept a note of the time. Once the twenty minutes were up, he and Tomcat scooped the soaking tomato seeds from the beaker.
"The sterilization is complete. Next up would be vernalization. It's done similarly by soaking," Mai Dong said. "However, the soaking will take a little longer. You need to soak the seeds in water for eight hours, so you can soak them tonight and scoop them out tomorrow morning."
Tang Yue unplugged the heater and removed the beaker from the tripod. The precious water could still be used, and Tang Yue didn't wish to waste a single milliliter.
They soaked the seeds in water again. Soaking them for an entire night was to allow them to absorb sufficient water.
