Is it possible to have a smell free micro grow?

I need to know this too... if the smell gets strong in my room...

 

yeah. you build your box with a carbon filter and fans. eliminates all the odour

 

or you could try low or no odour strains.Justfinished flowering Northern Lights. Had no odour problems and carbon filter. Was not needed.
