We have had over a 50% success rate with seeds germinating this year. The lights have helped tremendously especially with the addition of an actual grow light. We are still using the single florescent lights too both of which have the cool blue bulbs. At this point we consider this experiment a success so hopefully we can keep everything alive from here on. There will be more plants/seedlings to put in the gardens way earlier than last year because we started the end of January this year.
