Totally depends on the strain as to how much it smells.. Good ventilation is the main thing i guess because last year it got HOT (35 C) thru the summer..
I got the glade automatic spray lavender on the wall and a bunch of refils for it and just set it to spray every 30mins during the flowering stage and it seems to help alot with smell. I have now drilled holes in the floor to bring up cool air from under the floor and an extractor up top sucking hot air outside which blows over my vege garden where no one walks as its large so the smell really just dissapears before anybody can get a whoft lol.
Yea up the top is lots more light im gonna top and make my plants bush more this time should be nice
Its actually a much larger greenhouse, I just built a frame and put up a wall near the back so that room i got in the back is my little secret
