Day 7

It seems that the plant in the canister closest to the bottom of the picture is starting to shrink in size again.  We tested the pH and it was a bit high.  We mixed a new batch of nutrient solution and replaced it.  It also seems that the caulk that we used to seal the canister is starting to rot through.  We haven’t thought of a fix to this problem yet.  perhaps the caulk disintegration is the cause of the high pH level.
