My first post on this site and it is my first time growing. I have made a cardboard box that is a decent size. I have totally covered the inside with aluminum foil for reflecting light. I have seen many videos and sites and the lighting principle changes quite a lot. My seeds are currently still germinating. When the roots pop out and i plant them in solo cups I should be able to fit about 10 cups in my box with still a pretty decent amount of room leftover. once put the cups in the box, at first how much light is required and when should I add more light? Im going to put a fan inside but probably not an exhaust fan. what are the downsides to that? thankyou very much
