I'm gonna need to do that too, what kind if sulphur product do you use, is it powder?
I got a sweet deal, I got like a 25lb bag of raw elemental sulfur (granular) for like 10 bucks. It's basically a powder, very powdery in my opinon, lol. This super old nursery busted a lock off a shed that had been locked up for years and years, and they pulled out all sorts of fertilizers that would probably be considered raw explosives by today's laws. Anyways, I just got the bag of sulfur, I don't need anything else in my house with a grow room and a few plants on my deck. I just grab a scoop of that, throw it in the sulfur vaporizer, plug it in and walk away for about 20min-2hrs. Time seriously varies because that could be anything from killing mildew before I sterilize an empty room (could even be 3hrs if there was actually a PM issue) to a room full of flowering plants.
These times aren't scientific or anything, it's just what I'm comfortable with. I've had a sulfur burner left on overnight on plants that were at least week 6 in flowering. 8 hours of sulfur burning and they got a bad toxicity, they kept growing just fine, but they were black, purple, and yellow. I'm sure I lost yield, but amazingly you couldn't pick up the smell of sulfur on any of the buds except for one plant, which was just a small clone that was thrown in there for shits and giggles. Any yield I lost was gained back in the value of extra dark purple dankness. Either way, I'll never do that again and I would never recommend it to anyone, just a cool story.
I don't know if you guys know this, but TWS grows some great fucking buds, which happen to make the best fucking hash. I am, once again, faded as fuck on TWS hash. And I thank you.
