Dont feel bad. Its my problem too. I try not to even go to the spot everyday.After taking a second look it appears as that another individual has dampened off as well. The third looks like it might make it but I am not hopeful.
So, what did we learn here?
1. I have been wanting to use a different mix for seed starts as am not too thrilled with my current batch of recycled soil. Here on out I will be germinating in a different medium.
2. I own a Jump Start heating mat and while at the hydroponic store recently I saw they had the thermometer attachment. I wrestled with myself on purchasing it and I should have! It's ordered and will be used from now on.
3. I need to lay off the watering. I usually water by dropper only using a small amount of H20. My problem is I don't properly let the medium dry out in between watering, worrying about the seedling. I need to let go.
