"dumb" is probably the wrong wording.... im just not as safe as most. im the guy getting fined for not wearing a hardhat or mask.....im NOT the guy to get his work flagged. Nothing i do or say is "unsafe for your equipment" ...i may get ya zapped but you best believe your equipment will go unharmed HAHAHAHAHAH
People are always shocked when they find out I'm a bad electrician. :lol:

you will need to know whats on every outlet on that 20a circuit. If its just the light and the AC , then you wont have a problem very often but i would get that light off the AC circuit just because the startup draw on the ac is high and because you already heard the noise once. we dont wanna hear that again...ever. Specially if it was from the driver on the lights....... i would run an extension to the lights from another circuit. The lights dont need much but they need it constant. most sparky wouldnt agree and i only say things like this on a case by case basis but you can safely run that light on about any other circuit in your home....try to avoid AC's and the fridge.

Heavy duty extension cords are fine if you know what to look for. for 50ft an under i consider 14awg to be heavy duty. (not big enough for space heaters but usually plenty enough for the 1000 watt range)......for an AC unit , i recommend no extension or a 14awg under 25'. The "surge
protectors" are another ballgame. you wuold have to read the max rating on the surge strip itself....or the box.....

Thanks, luckily im in the north so the cold season is coming. Im going to remove the AC soon and that should help. Also upgraded my fans, surge protector, and cutting back on the load for that breaker because the breaker runs to a few outlets in the other rooms on the otherside of the wall in the grow room. I am pulling a max 1300w at full load on 20A breaker. No problems since and everything is checking in fine. New upgrades will be here this weekend. (1900w would start to see issues?)

the issue also happened the night after i tripped the breaker with a hair-dryer. not sure if this adds anything to the equation.

1900 watts puts you within code and safe. (with nothing else on that circuit) Your problem lies in voltage drop from the AC compressor or from the extension cord.

it could even be from a bad contact! If it seems to be getting worse over time it’s quite possible that it’s a bad contact building corrosion.
The house was just renovated and all the electric was redone a year ago by a fire Marshall.
I think it has to do more with my setup like @getogrow was saying.

I mean anything is possible though. I wont rule it out. I will feel a lot better about my new stuff coming in the mail tomorrow.

Well my electrical upgrades and new fan/filter came in. The AC Infinitiy has a nifty computer controller to really dial in the environment using sensor probes. Really cool stuff. Can't wait to have everything installed and set. My 12 girls are going to be very happy
