Anyone have any history with vibrating HPS lamps? Mine keeps making a buzzing/rattling noise. I’m thinking it’s the metal inside rattling on the glass so if I slightly rotate it it may stop? What do you think? Thanks!

Doubling light/adding a panel in flower
Adding a second light panel-- any tips? Will it be too much? I've been using a viparspectra p1000 in my 2x3ish closet and it's done me well up to this point. Today I've installed a second led panel (not as good as vipar). Wondered if it'll be too much?

Zu warm am Blätterdach
Hello, the next question: see_no_evil: What can I do to lower the temperature even more? At the canopy, it's 29-30.5 degrees Celsius. I already have 2 fans and the exhaust running at maximum level; it looks like the ladies are standing in an autumn storm. On the ground, it's 24.5 degrees Celsius.

Danger of Humidifier
Good morning everyone. So I've recently set up my new TS1000 and I'm wondering is humidifier dangerous for LED lights? It's directly under the light 60cm. And how can I regulate the temp in the room without new equipment? It's too high at the moment.
