They dont smell that bad during flowering, but Ive got 2 under a 250w HPS at the moment in my closet (yes, my parents DO know... it was them who gave me permission in the first place. A VERY long process, but once I told them the facts, they let me). One is around 40 days old, the other is about 24 days old. Yes, THEY SMELL. When you walk into my bedroom it smells, even with the window wide open. But my parents have said that its not too bad actually, they thought it was gonna be like stale spliff smell, but its really nice and fresh. If you could bottle it and sell it, youd be minted.
Aaaah, cannabinoid for men!

Oh, if you wanna lay the facts out to your parents, look through my posts... I told some guy what I told my parents, although I dont know if his parents have let him grow or not. Im not gonna say them again, if you hadnt made that outburst towards Turtle I would have.
