It was a pretty warm day today and I noticed that the temperature of my nutrient solution went up to 74 degrees Fahrenheit. From this morning to now, when I just checked, it looks like there's bee a significant growth of all my peppers(even the one I think is dying) and basil. The new growth is noticeable to the naked eye. Now I have to figure out a way to safely use an old aquarium heater in the styrofoam nutrient solution reservoir.
