Aloha Jensen,

As my students and I await the germination of the butter crunch lettuce, I had two other questions that I hope you could answer.

<br>

1) One of the suggestions was to use distilled water and a couple drops of lemon to help the seeds to germinate. Are there other “secrets” to helping the seeds germinate quicker using rockwool? #secretstohydroponics

2) If I wanted my students to measure the biomass of the plant, what suggestions do you have that my students (8th graders) could do to get the biomass of the plant? How could students measure the biomass before and after? Could you provide some steps that would be simple enough if I had my students do this. #stilllearningabouthydroponics
