carbon filters

quic question to everyone i started my grow in a small cupboard and then transfered them into a walking cupboard when they started flowering because they were too big but since they been in the walk in cupboard i aint put a carbon filter in with them reckon they would still be ok without the filter

Filters are used to eliminate odour.. If odour isn't an issue then neither is not having a filter.

If you like the smell loud then no, you don't need a flter

Yep filter is just for smell reduction.
