We were absolutely thrilled today to find roots hanging down into the nutrient solution from two of the cups. The healthiest looking plant definitely has the longest roots, which extend a few inches out of the rockwool. We’ve been waiting for this to happen for quite some time because it usually means the plants are growing properly. We are hopeful that the other plants will eventually extend their roots into the nutrient solution as well.
The lone plant growing in Perlite does not look as healthy as the ones in rockwool, but it’s much to late in the semester to germinate and plant seeds for a third time, so all we can do now is wait and see if that one hangs on to survive.
