Thats total bull bro..not true ..my plants stank by the third week of flower..there does not have to be buds for it to smell..
Just for the record..if tour vegging plant is stankin up theroom rt now when it flowers the ENTIRE house will smell..i promise that..my first grow was no filtration and I lived in fear thats how bad it got I got a carbon filter and now I could pack that room woth walkers and you wouldnt smell em Best move ever getting a filter
