not bad at all. actually pretty darn good! into week 6. smells great! soon as i open the door to the shop! then when the heater kicks on. wow! smells great!!!!!
Depends how many plants you've got. But for just a few plants, ona gel will work great.
Srategically placed plug in air fresheners work good too. Like right by your front door, also one just outside the grow area... maybe one in the hallway... anyway, i'm sure you get the idea.
air fresheners are nasty, personal opinion but i dont want to breath in that synthetic shit all day.
get some incense sticks (nag champa)
