You know you are being mentored by one of the best in grow town, so I'm not worried.
Keep it as simple as you can. Growing means you're always learning to adapt.
Feel free to drape a dark but not heavy, fabric over your tent keeping your vents uncovered. That will help cover the light leaks. Towels are good to use if it's not to heavy. I use a long skirt that is black to cover my spaces. Not sure if you have any available skirts in your collection...lol.
BTW, poetry in the mind is twice as nice. Trust me, I did a lot of prayer and poetry to make sure in my first year...hahahaha.
You gotta let it out somehow.
