Honey, that shits easy to kill. All it takes is a few bad microbes in the water (they multiply fast) & it starts to rot. I think you sell youself short. Its much easier to forget about house plants than what's in your grow closet. If you were to place house plants some where that would keep your attention like the grow closet did, I think you might impress yourself. How did you figure how much water they needed? I saw no signs of over or under warering. I saw perfectly healthy, happy plants! Your first grow? I think you've discovered an untapped talent. House plants? Most require more humidity than they can get (most are jungle plants). Some wwill burn with too much sun, but that's hard to come by indoors. Some need more light than they can get. A lot of modern window glass has uv barriers formulated into it. Usually, you have no idea if your windows do or don't or how much. So what may look like a sunny window to the eye, usually doesn't provide plants with the light spectrum/lumens they require. YOU were the one who had control over all conditions in your grow space. Every aspect was YOU! Try this; mount an under cabinet fluorescent grow light mid way of a window, add house plants (ideally 6" from bottom of light to top of plant ). Since your house has lots of open air space, the humidity is lower than your contained grow closet, so occasionally spray mist the plants. Water them as needed, just like your grow, but feed them less often. You didn't kill the house plants, the enviornment did. Take it from an old florist with a horticulture degree, when all the control was yours, look what you did! Now go do it again! Happy tokin'
