Morning Mate,
No, you don't want to have the lights on when drying your Buds. Light will break up THC. I open mine every day for 20-30min. Shake it to change Position of the Buds. I do it as long as I sense a haylike scent. After this point I open them just every couple of days.
Hope this helps.
Servus✌️
