Today I woke up at 7 AM and watered them. I believe they get direct sunlight very early in the morning, 4-6 AM I suppose. Still, the heat should be enough to evaporate the reduced amount of water I gave them today. Sadly, I saw more fungus gnats, so I used fly spray again. What are some other nontoxic ways to kill fly gnats? I will try to use nontoxic methods if they ever come back next time...
