The whole window will have a one foot wide window sill. I will have to show you the place to get a good idea of things. Basil planted in teacups for the kitchen, cheap and pretty teacups planted with fresh herbs on the window sill.
Growing fresh herbs in your kitchen. Great idea fill Mason jar with water use wine bottle cut off bottom run string down neck of wine bottle to wick water. Takes a few days before wicking kicks in. Great for herbs in the kitchen window.
