Honestly I thought it was possible which it is, when the plants are seedlings. And when the lights are off. And when the fans are off 
it’s literally fighting a losing battle mate wish it wasn’t the truth because I’ve spent a bit getting mine where I need it for the stealth aspect but there isn’t such a thing you HAVE to run good lights and some kind of fans in a grow.
I did like the 150W HPS bucket build @Filipo did this is about as stealthy as you could get and at that you would have to put this build into something or people would be like why does you have a bucket with fans and a light going?
