Hey guys, I wonder if I could put ballast on the wooden board because it gets really hot, but I need space and that would be an ideal place. If so, should i put between ballast and wood aluminium foil or something?
Thanks for all answers in advance!
It takes around 500 F for wood to spontaneously combust.
Your ballast will shut off long before that it ever reaches that point.
There should be thermal protection on your ballast.
If you can't touch your ballast for more than a few seconds your ballast is malfunctioning , generating excess heat.
As for mounting, get ascrap piece of dry wall mount that to your wall then mount your ballast to the piece of dry wall.
IMO- every indoor grower should have a fire extinguisher next to your grow room door.
