i need help! im a poor man trying to cook beans in a slow cooker! i need some help!

[Dr. Steve Brule]

just a improvised home-made recipe. i started with a bag of pinto beans that i let soak overnight, the next morning i drained them, added them to the crockpot with a 1 sliced up onion, a clove of garlic, 1 tbsp of Salt and a slightly cooked (stovetop) package of cut up bacon. after all that i added water to fill to the top of the lid. am i doing it fine?

Should i cook them on low or high? does it taste the same either way?
