Indoor any advice on getting rid of smell from plants

[Mr Piggy]

I did use white, and they were stinky as ever. You do know vinegar can drastically lower ph, yeah? Make sure to keep an eye on that.

We tried it both ways. we like the fan and filter outside the tent. the fan rests in a tote full of insulation to keep the noise down, the filter is attached to the exhaust side of the fan. a short piece of ducting wrapped in foam and tape connects the intake side of the fan to the top hole in the tent.
this gives more room for plants,lights etc. and gets that heavy ass fan and carbon filter weight off your tent frame members.
the addition of a ona block and maybe even ozone are a good idea if security is a big concern.

Hi what is a ona block and ozone? I am yet to buy my setup so any feedback would be great on getting rid of the smell I was thinking of getting two 6inch rhino carbon filters one at each end of the tent both inside the haveing the ducting near a window?
