So, I have discovered that tomatoes need a lot of light. Mature plants need more light especially if they are going to flower/fruit soon. So I am increasing the light on my mature plants to 18-20 hours per day. That should get them to flower/fruit. 🙂
The seeds and seedlings that I have started for outdoor transplanting will still have 12-16 hours of light until they are larger.
I am also going to fertilize the mature tomatoes for 2 weeks when I water them. That should give them enough nutrients to flower.
I will keep you up dated on their progress!.
