I start out my vegetable garden indoors in my pre-grow room under cfl's as the weather is usually not good enough to start out outdoors in the beginning, but as soon as I can put them outdoors I will as I don't really feel like wasting too much electricity on growing vegetables.
I also grew some magic mushrooms (golden teachers) indoors not too long ago for the first time, which was an interesting experience. It doesn't require the amount of patience that's required with growing weed as it grows a lot faster once it starts growing, which was a relief for me as I'm very impatient and always have a hard time having to wait months for a cannabis plant to finish flowering, especially when I'm out of weed haha. So awesome to be able to see some mushrooms pop up and then a week later you can harvest them.
