In a 3'x6' cab I use the sulphur for about 15 minutes AFTER the sulphur has melted.

Then another five minutes with the oscillating fans on.

Vent fans off.

Too much sulphur will really screw with your new, tender growth. Five hours could conceivably kill the entire plant. I went for about 45 minutes one time and it really screwed with a lot of the growth.

I hang the pot in the center of the cab. You want the sulphur vapor to get on all your leaves.

I do the sulphur thing during lights on; but I hang a 65 watt cfl in the cab and turn off the big lights cuz, obviously, you can't use them with the vent fans off.

A little sulphur goes a long way, and it can be re-melted. Take a good whiff of the vaporizer when your new sulphur has just melted. On subsequent uses you should be able to smell when the vapor is no longer strong enough.

I usually treat every second or third day until the problem is gone.

Good luck! :thumbsup:

PharmaCan Reviewed by PharmaCan on . Sulphor Bombing Borrowed the one from my buddy that hangs on the ceiling and you throw the little sulphor pellets in there and plug her in. I am curious about a few things. a.) does ventilation have to be off? b.) where do I hang it? right above the plants or in a corner? c.) how long does ventilation have to be off for... five hours or so like a regular bomb? d.) how much of the pellets are you supposed to use? he said it's enough for one burn but i want to be sure.
