Sorry not joining in. I'll save windowsill war fights for early spring. I don't think he could cope with myriad pots with indeterminate seeds/seedlings festooning the sills all winter. As it it is the newish enclosed porch is still filled with tomatoes and dianthus. He made the mistake of replacing the shelf that used to be there before refurbishment and now I've populated it. I wonder what he thought was going to happen?! I will of course follow your progress.
