The only requirement is that the plants receive a fair amount of light during the day, so place yours close to a window.
Cut out an opening in your countertop to accommodate a stainless steel tray. You need a tray that has a lip all the way around to hold it in place.
You can use a jigsaw to cut out a hole in Formica or laminate. For granite or concrete you will need an angle grinder (messy!) and a suitable cutting disk.
You can use a plastic tray, but stainless steel will look better once in place.
Shop around at catering supply companies for a suitable sized tray for your herbs.
Create a substantial layer of gravel for drainage at the bottom of your bed and then fill with a rich organic soil/compost mix with a bit of perlite added sufficient drainage and aeration.
You can also drill drainage holes and use tubing to divert drain water to a bucket or back into your sink drain.
Pot up with plants that are easy to grow indoors, such as herbs. Plant things you use on a regular basis.
We did put a mint plant in ours and buried it in a separate container so we didn't have to worry about it's invasive nature in this small of a space.
Be sure to position your bed where you can get as much natural light as possible and if necessary, compliment with a growing light that can be positioned and installed underneath a cabinet.
Water and feed as needed.
You can also have fun with countertop salad bowls and the like. They give you easy access to fresh greens year-round and it encourages you to always make healthy, lively choices in the kitchen!
