Know your roots

In case you missed the first few weeks, past posts on this project can be found here.

Do you ever think you know what you're doing, and then realize that you've made a simple, but glaring error? Turns out our math was wrong with our last update and those wonky numbers should not have been so wonky. Oops! Sorry guys, but we're back on track now.

When we start this project over again with new plants, we have some experiments planned that will help us to determine exactly how much water soil can hold and how to make sure that the soil is evenly saturated every time we do a weigh in. Hopefully this will give us a much more consistent weigh-in from week to week.

We would like these guys to grow a bit more, but we'll likely start a new batch in March 2020. Follow us on Instagram and keep an eye out for your opportunity to vote on what plants we'll grow next!

Today we wanted to show you one of the most interesting observations we've seen in the project to date. Take a look at these roots!

We know that plants are capable of growing different types of roots depending on their growing medium. Roots grown in water adapt to absorb nutrients in a different way than roots grown in soil. In theory, both the semi-hydro and deep water hydro roots should be water roots.

However, there is also a theory that having a small fan blowing across your plant as it grows helps to strengthen stems and leaves. It simulates a natural outdoor breeze and causes microscopic tears in the stems. The stems then rebuild to become stronger and more resilient. Perhaps this is what is happening with these roots as well.

The semi-hydro roots, in the middle, are growing in still water with no movement, so they're very fine and thread-like, and we expect they'll break easily when we try to remove the plant from the clay pebbles.

The deep water hydro roots, on the other hand, are growing in constant movement. The airflow through the container keeps the roots and water moving 24/7. As a result, the roots have adapted and are growing thick and strong.

We're looking forward to seeing how they look in another month or two!
