as the title says my grow lush 400w ballast is making a fairly loud POP/Bam Type of Noise, roughly every 2 minutes x.x amount of seconds.is kind of worrying i have no idea if its electrical or if its meant to make that noise for whatever reason, please help take some stress away, should i take it for repairs or its meant to make a noise every 2 minutes.
P.S its an energy saving 400w digital ballast. first time use. never been used in a grow.using a PowerPlant SUPERHPS 400W also first time use.
i have not tried a different wall socket i shall when its lights off time., it will not run a MH bolb either kind (retro) and the newer one, runs all hps just fine. if it continues tomorrow i shall take it the repair place, thanks for the helpful information, btw running a 6" cooltube no ducting or fans (setup for the cooltube) at this moment but i do have one on the seedlings keeping any extra heat off them and adding strength to stems/growth, tho my temps are fine i believe, 42% humidity and temp is running at around 28-29 degree's at the moment , ( keep in mind im using the dim able switch its on 75%) out of ( 50% 75% 100%, and Super lumen's )
