Yes, tomatoes like lots of sun so this fits. Though I would say if your tomatoes are sick, they will likely need a different colour.
Can't wait for the spring! All I have are peas & salad stuff at the moment. The beans should be making their appearance soon in large beds so will do another full spectrum colour test on them...

And I can't wait for spring either!!
Yowzer! Can't grow much in that.
Just out of curiosity do you know if there are any vegetable which can grow in thick snow?
I guess they just get covered up so nothing much works unless the snow is removed?
Actually the ground freezes, sometimes to 4' down. Once soil temp drops below 50F, the biology slows/stops. Add the lack of sun in winter (only 8 hrs this month) and nothing is growing as it doesn't have sufficient support.
