Ok, so im growing 4 plants in 4x5x8 room and running t5's on 24hr cycle. My last grow had some PM issues so I bought a sulfur vaporizer for prevention. My local grow store told me to use once a week for 1hr w/ lights and exhaust turned off. If im using 24hr lights how do i pull this off? Is it ok to turn lights off for that hour? Also, no instructions came with vaporizer and im wondering how much sulfer i should put in the bowl. Actually, any info about prevenitive sulfur vaporizing would be helpful. Thanks for any help you can give me!
