| Greetings, I also started geraniums the first week of February! I started pink and white geraniums. They have the second set of leaves now...the zonations are evident on the pink plants but not on the white. I don't think the zonations are related to the light but are just a natural part of the plant's coloring. I also have my lights on for 18 hours a day. I started geraniums a couple of years ago from seed and had great success with having the lights on for 14 to 18 hours a day. I have found this site which has some information on growing geraniums from seed. I pasted the link in below.
