Long time lurker, first of many questions to come. I’m currently running a 2×4 AC infinity tent with a 4 in carbon filter that’s had two successful harvests with a total of 5 months of continuous use during flower. I’ve grown 4 plants total so far on this filter but I’m also in an apartment and need to avoid smells. The filter has run great for me so far but I’m aware that it needs to be changed out. My question is, how often is the carbon filter supposed to be changed out? Everything that I’ve looked at online says different things so I thought it would be best to come to the best community I know for their opinion! Thanks in advance DGC and let’s keep growing the dank!
