Who has real experience with sulphur burners

Never had it in my life and been growing herb for 20 years now but recently got both of my vertical rooms and vedge infected with the infamous powdery mildew.... Since first signs of this shit I have researched this topic to death and tried a few different things now but want to take a more aggressive approach as to get my rooms back under control.... I know a lot of masters say you got get rid of everything, clean the rooms and start over, but I am working with genetics that I will not give up and are all Original strains of my own.... I was born and raised in Humboldt and many of the F1's you hear about today, like Trainwreck, Ice, ww, and blueberry came from these genes.... Anyway.... More to the point, I am ready to purchase a sulphur burner as to prevent further outbreaks and maintain a more detouring atmosphere.... I know al use to use his religiously, but how far into flower is what I want to know..... just interested in hearing from growers that have had real experience with a sulphur burner... I have read don't ever use a burner in flower, to hearing about people burning lightly all the way through...... I opperate a very small collective now in north county SD and it's completely connoisseur based, so the importance of maintaining the quality of herb that my members are used to is crucial... FDD, if you are reading, love to get your input, and you too Earl..... Thanks to all who read and can offer some help... Also for bonuse points, if anyone has experience with greencure later into bloom, would be interested to hear more on that topic as well, other then that, ladies are in killer shape right now, but the PM has gotten close to some flowers on certain plants. the Greencure shut it down, but do not want to be spraying and searching every other day for the rest of my grows..... thanks again guys and keep pressing for that exotic strain to call your own......... Too many strains so crossed out there now that they all just look the same and smell the same.....

bought a sulphur burner today and some zone and penetrator by DM.... Greencure didn't wipe out my room at all... in fact after a heavy spray with the recomended amount per quart, I had some areas the next day that were covered and some areas that showed improvement.... this Powdery Mildew sucks.... dehumidifier, proper intake and exhaust, all conditions are close to optimal, other than CO2 induction, but I have been there and prefer not dealing with the hassles and just running good exhaust and intake I am close to same results.... Anyway, all things correct and this fungus is thriving... now underway like many before, having tried Milk(Nonfat diluted), H2o2, just plain RO ph up over 7, and now Greencure (potassium Bicarbonate - very popular choice today in maintaining Organic Horticultural practices) and will now Burn Sulphur and Use DM if I decide to spray again... I realize I created this mess and I am ok with the hard coarse of trying to get things back together.... all these practices are what improve my gardening...

Update.... Been using the sulphur burner off and on with greencure... Results are good I suppose but spot treatment is needed daily with greencure and pure sulphur does not smell as bad as I thought... I also drenched plants with sodium free seltzer water... No burn and direct co2... Done it for years and now benefiting by rinsing sulphur vapors!
