I am growing White Widow quite a stinky strain & mine didn't start getting 'smelly' until at least 4 weeks into flowering.. as long as you have some sought of good anti-odour product like ONA gel, a Ionizer or a Carbon Scrubber you will be ok + good ventilation etc.my plant seems not very smelly at the moment 5 days into the flowering cycle ,is this normal,the seed came from some real smelly smoke
