I got a head start on some of my perennials this winter. I had an extra 400watt fixture not in use.

I have a bunch of cuttings and seedlings that have their roots filling up 4 inch band pots that are a little over 4inches deep.

Since spacing under lights can be a premium. Has anyone used the 4 inch band pots that are 10inches deep with good results ? If 10 inches is too deep, they get to go into the cold frame
