Most of our windows are north facing, which is good for not heating up the house in the summer, but not so good for growing green onions in the winter. So to boost the light level, I purchased some LED grow lights strips and installed them under my cupboard in the kitchen.

I put a new batch of roots in the test tubes and they like the new light! The picture shows about a week of growth. Now the previous batch made it through three harvests before petering out, we’ll see if these keep going.
