The last time I was in Amsterdam, I smoked Shiva, and it kicked my ass all over the floor. That's the next strain I want to grow, but it's gonna be a stinker for sure. I'm already designing out a killer odor scrubber, and if I do it right I'll put the plans online. It's the same theory as the existing carbon / charcoal scrubbers, except that I don't like how the exhaust isn't more streamlined. I want the exhaust from the scrubber to come straight out of a dryer flexible hose, so my room can be relatively air tight, except for a filtered exhaust. I think this design will be able to facilitate a double ventilation to boot, where you would have a primary and secondary stage setup.
