Thank you all for the kind thoughts for my light rack! It is great to see the positive replies.
I have some improvements in mind for this year.
First, I want to add rollers on the bottom. I don't get a lot of light at the basement sliding glass doors, but some is more than nothing.
Second, I bought reflective mylar sheeting to use in the garden. I could use some of it to maximize the light from the light fixtures.
Third, I am also considering mirrors attached to the back of the light rack.
Fourth, I am thinking of changing my timing lights from 14 hours to 16 hours. I'm not sure about that. One part of me says that more light is better, another part says mimiking natural Spring lighting is best for seedlings in the Spring.
Thoughts?
