I was planning on growing in my closet for the first time. If I have the soil, germination, and lights will it somewhat die or get moldy? Or is it a must I have to wrap that silver shit around my closet. It's a 3' by 4' closet. Thanks.
The 'silver shit' is all about maximizing the light. Necessity, no. What color is your grow area? Good luck.
If you have a nice air intake and exhaust, fans set up you should be fine, it's all about air movement.
