Hey dude, good luck with the new grow. Just wanted to say something quickly, though. I'm an electrician and the wet towel method your using is very, very dangerous and should be removed immidiety. I'm not gatekeeping here, my friend, it is just a fire hazard and at the very least will damage/degrade your qauntam board(from the driver, looks like an sf-2000. Awesome lamp)
I use a pan of water with a heat mat under it and a small fan blowing over top to achieve higher humidity, for free. There is a hanger, tea towel and bowl of water method I highly recommend, which is about the same thing. Maybe the easiest solution is to take those towels and put them on hangers near the light or with a fan blowing over it. I achieved +20% RH during my drying period by doing this.
Please consider and happy grows growmie. Cheers!
