Mi plants die as soon as I place them in my WF

2:38 pm in Plants, questions, Seeking Advice by Paula

I am having trouble keeping my plants alive. I just started my WF and I have already tried to put several plants and they all die soon after I place them in the WF. Yesterday I tried putting a beautiful mint plant and it died after about half an hour of being in the WF. I have tried also some Cilantro, and the same has happened. My feeling is that the window is way too cold for these plants. Could this be the reason? I have checked the PH and it is fine…the temperature of the nutrient solution is 20 C. But my beautiful plants keep dying…Can someone please help me!!!
