Our plants seem to be doing quite well. More stems have emerged and new growth is evident. Our water culture system is working well up to this point. The growth rate has increased since the plants have been moved into the growing system. One problem we did encounter was with the pH of the nutrient solution. When we checked the pH, we discovered it was up around 8. We added pH down until we reached around a pH of about 6.5. The next class when we checked the pH again, it was up to about 8 again. Again we lowered the pH to about 6.5. I am not sure why this is happening, but the plants seem to be doing well up to this point.
