Wow!!!
Today we checked on our system and we were very impressed. We had high hopes that the lettuce would be as big as our previous planting; however, it has passed that by a long shot. Our lettuce has grown so much over the weekend. The plants look very healthy and very green. The air pump was still working perfectly and the water level was still good enough, but we added more because it had dropped a little. The pH level was a little high so we lowered it again to about a pH of 6. The plants have a good cluster to them and seem to be taking off real fast. Were excited to see what next class brings!
No we did not. Were not sure what the problem was. We originally thought it had to do with the light, but these new plants are doing amazing. However, we did change all of the water this time and added the nutrient solution right away, so maybe this made the difference. We were very curious ourselves as to why the first planting dried out, but we are happy with the direction our plants are heading!
Its good to see that your system is doing well now. Did you ever find out why your plants originally dried out?
