I bought the florescent bulbs that mimic the Sun and put muskmelons, basil and peppers under them. They are in the basement where very little natural light hits them. They started turning yellow after two weeks. I fertilized them. I leave the lights on even longer, twelve hours now, and the yellowing happened even faster. The basils and muskmelons appear to be lost. What am I doing wrong? The lights are about six feet up on the ceiling, the pots are on the floor. The melons also got a case of powdery mildew which didn't bother them to much. I lost a number of chiles. They just dropped leaves and never recovered when I brought them in. Also, two of the three Kaka Beaks withered and died within two weeks of coming in. Karen kstober@us.ibm.com
