Today we checked on our system and it is doing amazing! We are so impressed with the results that our lettuce has shown. The plants all look very healthy and are starting to grow into a very full bunch, which is so cool to see. They are very green and seem to be improving even more each time we check on them. The only thing we had to do was add some more water to the system because it had been a week since we had checked on it, due to our field trip last Wednesday. After adding more water to the system we checked the pH level in both PVC pipe holds. The results were perfect and dead on where we wanted the pH level to be at. The plants seem to be adapting to the system very well and were hoping to be able to harvest them shortly!
