Hi SunLake,

I have a carbon filter also, but have yet to use it on any of the 3 grows I have done so far, so cannot help much aside from saying you probably wont need it until your plants are at least a few weeks into flower. I doubt your plants will give off any noticable odour until this time. Looks like you have spent a fair amount of money, hope you manage to dial in the setup! :thumbsup:
