sulfer vaporizer - sealed room

[compash]

here we go again... another exciting sealed room thread. it seems not many peole have rooms like this and its hard to get information. when i bought the sulfer pellets the hydro shop told me to burn for 3 or 4 hours, 2 or 3 times. im one week into flower, i hope its not too late to start this. but the problem is, my room doesnt have exhaust, and i read to exhaust before entering the room, which creates a conundrum. maybe i should just spray with defender sulfer spray or something. but that will only kill the spores on the plants, not the surfaces of all the equipment. this is preventative because i had powdery mildew bad last cycle [i couldnt provide the herb as medicine this time:( ] but the strain im growing now didnt get it even though it was next to one that did. so i just want to make sure it doesnt get it this time! any tips on sulfer vaporizing a sealed room?

find a way to get some ventilation. the only answer i think is apropriate. you grow SHOULD have ventilation anyway. the fact that it does not probably contributed a great deal to your PM. you can still leave the room sealed in other respects but some kind of air exchange is really important.

on option with what you have is to do the sulfur at night when the light goes off. in the morning open the door and leave it open for a while before entering.

pflover, thanks for the advice but...
i almost always got powdery mildew with the room exhausting. big intake fan and big exhaust fan.this is the first cylce with the room sealed. one of the principles behind sealing the room is to prevent PM spores (as well as insects etc.) from coming in. my lights are on at night and off in the day, if the door is open when the lights are on, the whole world will know im growing, if the door is open when the lights are off, ill interupt the dark cycle and that could cause problems.
i guess sealed rooms, the perfect room, and CGE closed growing environment, is still in its infancy for ganja growers. i had a real hard time even on the old CW to get information from people experienced with this style.

Compash;

I'm going to go out on a limb here. I am inferring that the purpose of burning sulphue is to generate SO2, or sulphur dioxide.

If this is correct, you can generate SO2 with one of a pair of common chemicals used in the wine industry. These are Potassium Metabilsulphite and Sodium Metabisulphite.

You can mix these dry chemicals with plain water at the ratio of 1 tablespoon per US gallon.

Then pour the liquid into 2 litre plastic pop bottles cut in half. You only need 1 or 2 of these per plant. Close the doors up and shut off any fans you have that extract. Leave the room fans on to circulate the SO2.

Open the doors in the morning, and allow the room to air out, or turn on the extraction fan.

What is it going to cost you? A couple of pounds of the Metabisulphite should cost less than $10, and will make up about 100 gallons at the rate described above. It will choke you if you breathe it in, but a wet cloth over your mouth and nose will absorb the SO2.

Even a sealed room should have an exhaust for this exact reason.

Just to clear the room of sulfur, poisons, heat, paint fumes, excess CO2 and humidity in case of need. Not all the time, just for times like NOW :)

If you are reducing your humidity enough (no PM), you will have to burn sulfur very rarely, perhaps just this once to coat the room.

What is your maximum Relative Humidity over a crop cycle?

Perhaps the de-humidifier is too small for the job? You did say it gets hot and runs a lot?

PS Every "Perfect Room" i've visited had a vent fan and intake for emergencies...

lucy's,

i already own the burner and the sulfer, so i might as well stick with what i got. but that is an interesting technique, are those chemicals available in stores?

green med,

i guess ill have to re-connect the fan to the exhaust duct (whew, good thing i left it in place) for the burn.

this is my first sealed room trial (but im plenty experienced otherwise) and the humidity gets up to about 70 in the lights off time, but stays down during light s on to about 40-50. the machine doesnt get hot per se, but it blows hot air when its running.

im curious to hear more about the rooms youve seen, theres not to much discussion on perfect rooms anywhere that i can find on the web

thanks folks, compash

ps, im about 12 days into flowring, can i still burn sulfer?

[Green Medicine]

Compash,

The "rule of thumb" is don't burn sulfur after the first 2 weeks of flowering.

Good Luck

Either of those chemicals would be available at a home wine and beer supply store.

My sulpher burner is on for 3 minutes then off for 15 then back on for 3. The sulpher barely gets hot enough to release much into the air!!! It is the SULPHER VAPOR which helps guard our ganja against POWDERY MILDEW!! The mere presence is enough,,,with a little heat. There are no residuals on my medication. I have also been using the same 3 $ batch for almost 1 1/2 yrs. he he...get a sulpher burner and you will not have to worry about mildew again as it basically dries out the spores. God Bless....he he...:D :D

As a certified pesticide applicator I have to suggest against using a sulfur burner. Correct use (atleast by my state regulations, yours may vary) requires that you not enter the room for 24 hours after the burn stops and vent the room afterwards for 4 hours before re-entering. Sulfur vapor is nasty stuff and ranks as my #2 hated pesticide to apply (Nicotine burns are #1). If you consistantly get PM problems you need to do one of two things to fix it.
1.) Fix your environment. This will fix most of your problems. You room has an environment that allows PM to grow. Change your conditions so that it is hostile to PM.
2.) Fix your strain. Perhaps the strain you've chosen is susceptable to PM, can you get a PM resistant strain or just try another strain?

I really hate hearing people suggest using a burner without also suggesting appropriate safety precautions before, during and after use. Please watch yourself and others, sulfur vapor is not good for your lungs.

thanks for all the great info mendrel... every hydro store, every grower's guide, every internet guide suggests that no grower should be without a sulfer burner!

i burned yesterday for 4 hours, the sulfer pellets became liquid but there was no obvious vapor or smoke or what have you. i could smell it a little. i exhuasted for several hours after the burn.

my environment is all different then it ever was becuase i sealed my room and installed an a/c and a co2 moniter.
in my last cycle i had 2 strains, one was covered in PM one had none. this time im growing only the one that had no pm, im burning just to make sure i dont get it again.

[Pothead Pete]

I never stated to inhale the vapor. And of course the room always is exhausting.:D :D

Neither did I, even when I have to burn it I'm in a thick rubber suit with a powered, filtered air source and I still don't like breathing in the same room. Gives me the heebie-jeebies just thinking about it.

I have to agree with this post. Sulfur is some nasty stuff and should only be used with EXTREME caution!

Here is a link that might help you come up with some alternatives but like Mendrel mentioned your best defense is an offense in this case. All that aside, there are about a dozen different treatments for PM, HERE (http://*************************/articles/2250.html)is a good link i have used in the past:
