1000 watts

I grew in the past, it has been 4 years and my best yield was 3 pounds using 3 1000 watt hps lights and general hydroponics 3 part series with Rock nutrients resinator. I topped the 12 plants but didnt train them, I defoliated only during flowering. I let them veg about 2 months in dwc buckets...

First time posting, how's it growing everybody? So I'm' about to start construction on a 10ft high, 7ftx18ft room. It's in the back of my uninsulated garage. I've got 3 hydrofarm raptor hoods 8". What's the best way to cool these, without letting the neighbors know what's going on? Quiet is key...

My 1000 watt grow light sometimes doesn't turn on. I just had my 3 week old plants sleep for 12 hours I am worried they might flower early. Also does anyone else have this issue with there light? I have a fusion bright dimmable ballast. And HPS 1000 watt bulb
