Rainbow tabasco required nothing but water, ime - if you have decent sun or a grow light.

They cost a bit but they are idiot proof. The company also sells materials at an Okay price to grow whatever seeds you want, and you can use standard hydroponic supplements rather than their name brand ones.

I got a kit with Basil and it grew more Basil by accident than I could use. I was ripping off leaves and throwing them into store brand pasta sauce. I had a single plant in one of the $100 growers.

Their "salsa" kit is cherry tomatoes and Jalapenos so maybe it won't work so well on other peppers, but they have a Banana pepper kit. Pepper growers might have nutrient and growing recommendations to better manage flavor and spice profiles.

Pepper plants are really easy to grow. Pick seeds that sound like they’ll yield the flavor you’re looking for.
