Are sulfur burners safe for clones?

[20sackzack]

I am posting this in the infirmary section as well but I was just wondering if anyone has experience with using sulfur burners to control powdery mildew in a room with mother plants and rooting/rooted clones? Will the sulfur damage the clones at all?

For me, sulpher candles/burners have been a nightmare. Most say on them, for cleaning greenhouses before the season.

It's a shame hydroguard is so weak. You can buy

bacillus amyloliquefaciens D747

from cheap sources though. Which has foliar application for PM as it's main purpose. It's about $100 a sack. IIRC 'southern agriculture' have it in the states. Packaged in manageable amounts.
