Hi everyone! I was wondering if anyone has any tips for tomato growing. I have some seedlings growing under a two foot fluorescent light, on shelves inside. They have all sprouted, and have their two seed leaves. Some are beginning to get baby true leaves. Their stems are slightly purple... is this normal? And how often should i be watering? I have read many websites that say to water when the soil gets dry, but i'm not sure. I don't want the seedlings to wilt! And also, does anyone have any favorite tomato varieties they recomend? Thanks for any help!
