I live in a medium sized apartment with 2 bathrooms one of which we do not use. I'm wondering if this unused bathroom would be a good growing room? There is a under the sink cabinet that is 78.74 cm wide and 60.96 cm tall that I thought would be good to start the plants in. Once they begin to grow, I was thinking of putting them in the shower with mylar all around to reflect the light. I have been reading all of the newbie growing threads and instructions and I haven't seen anyone else who has used a shower as a grow room...I was just wondering if it's a bad idea.
