This is only my forth winter of starting seeds inside. There is one thing that still puzzles me. During the day and part of the night - I turn on the lights for around 16 hours. The other 8 hours are spent in the dark. The plants always grow much faster in the dark. The next day when it's time to turn on the lights, I have to adjust the lighting first because the plants have grown into the lights overnight. I have noticed the same growing habit with outdoor plants too.
The reason why I'm still using the old T12 light fixtures is because I have six fixtures and a case of tubes just sitting around wanting to be used. At the rate of their longevity, it looks like I'll be using them for the next 20 years .
Yes, I'm the kind of person that drives a car until it is no longer worth fixing.
