The past week and a half have seen continued growth of our lettuce, as we continue to see results moving towards an eventual second harvest. The last week, we have continued to monitor the water levels, pH and temperature- all of which have been pretty stable throughout the entire growing process. On Monday, I mixed up some additional nutrient solution, which we needed as we were running low from the first batch we mixed up. After adding the nutrient solution, we saw a much more balanced level of pH, which was a little bit lower before adding it . Additionally, we saw a slight increase in the measured temperature of our nutrient solution/water. We figured this was due in part to the newly added nutrient solution. Today we came back and measured the temperature and pH levels, which were holding pretty stable at 72 degrees and 6.5 respectively. In addition, in just two days since adding the nutrient solution, we saw an increased growth in the lettuce. This is due in part to the new rich-nutrient solution we added. We will continue to monitor pH and temperature levels and touch base next week!
