Its all good, thats what this site is all about. helping your fellow herb grower. I do fold the flaps down, and my humidity is low, so the flaps down help regulate the humidity. other wise it would bring in dry air. LIGHT DOES degrade thc so you do not want light in. after the dry, I place the buds in light tight jars for the curing. I noticed to that the light can affect the color of your buds, turning them a darker color. the air temp should be around 70 degrees farenheit. not sure on celcius. If you have good drying humidity then a small fan bringing in fresh air is ideal. Hope this helps, peace.
