Its not a bad idea to try as long as you don't get your hopes up and don't get too frustrated with problems. Start with easy plants. Does that window get good sun all year round?
My 10g I use to let my cherry shrimp do it and make more, but I also use it to grow moss walls, moss bushes clipped stem plants and store plants that I want to trade. This tank was low tech with a regular fluorescent fixture that I turned on when ever I didn't forget. But it was in a window. Plants grew FAST and rooted quick. I never cleaned the glass bc there was no algae, and I never vacuumed the gravel bc there was baby shrimp in there. water change every couple of weeks, a hob filter with just 1 piece of floss no carbon or anything.
Walstad works, but keep it low tech. No ferts, no excessive light and no co2 or excel.
Use that if it helps.
