This is the easiest “gardening” I ever did. I got four-inch pots, six of peppermint and six of spearmint. It’s hard to see in this picture, but these pots are standing in about an inch of water that is always there…in the summer anyway when I’m running the a/c all the time. What appears to be a tray is just a frame with no bottom. Does this look okay, dracoi?
I was going to totally endorse the mint idea. You can put them in much larger pots; they will fill them up quickly. They will love that spot.
here’s a recipe since you’ll soon be wondering what to do with all that mint
Mint Simple Syrup
1 cup water, 1 cup sugar, one cup spearmint leaves (or any equal proportion).
Cook the water and sugar to boiling. Take mix off the heat, stir in leaves, cover and let steep an hour or two. Strain out the leaves, store syrup in a clean glass jar in the fridge.
Add a couple tablespoons to lime juice and rum for quick mojitos… makes a nice gift too.
That sounds an awful lot like Real Gardening. :dubious:
Yeah, baby. 
Hmmm…interesting. I have cats already and they do, in fact, have tails.
I knew that.
But can you use cat tails to make mojitos?
I think that looks great! That level of light should make for very happy mint.
I will second Hello Again’s idea that bigger pots will probably serve you well. My mint plant took about four weeks to go from the size of one in your picture, to filling up an 8-inch pot. Some varieties will practically turn into bushes if you let them.
And I definitely endorse the mojito idea, though I do mine more traditionally by muddling the leaves. Mint leaves in iced tea is another major use for them at my house.
Nah, you just fling 'em in any kind of cheapass planter any which way, pat in some extra bagged soil. Boom! I think my peppermint took a weekend to fill in a 6" pot.
Real Gardening ™ is when you decide to take a break from your negligent planticide of Pothos (aka The Easiest Plant in the World™) an round out your mojito garden with a lime tree. Next thing you know you’re talking sagely about Cushiony Cotton Scale and root pruning and zinc deficiencies and mixing your own soil and then one evening you find yourself testing the ph of your tap water in case the lime tree doesn’t like it and you think, “how did I get here?”
Don’t ask me how I know. 
Sounds to me like you need a koi pond. Don’t ask me how I know.
