PM on newly rooted clones

Is the sulfur toxic as long as its not wiped down? How long after its down burning is it not toxic?

Any residue is going to be slightly acidic.

I wouldn’t burn sulphur inside ur house that’s fosure, it’s not worth it And like many things tradional can be harmful to you in bloom but also degrade it easily. Why risk and use such when many proactive and safer choices. It’s not like cost is stopping ya

For a veg stage-start Of flower I would suggest using a product like suffoilx or des-x and mix wiyj products listed below aka biofungicides (explained under). apply at 2.5 every gal and make sure ph above 8.0 and mixed last via foliar. These products will work great against broad range of bugs with no resistance issues and per gallon are a great deal. you can apply these with many products just not npk based and used as many times ( just have to wait every 7 days before next spray )


For biofungicides I use regalia both drench and foliar, foliar once every 7 days at 30ml per gal, drench I do it at 15ml/1T a gal every 2-4 weeks. I also mix in southern ag biological fungicide drench @1-3ml every 10 gal (I apply every rez) & same with drench the foliar of SABF 5ml (preventive rate) - 15ml “high risk/infected to molds rate ) , key with regalia drenches to make it effective and less costly Like many tea’s or brews is prefeed/water ur medium firdt to 75%+ and than apply the regalia/SABF tea like many ipm drenches and taht will save ya a bunch and give you same results. Key is full saturated and no cap and gaps in ur drench in that and to prefeed/drench it def will help that aspect.

this method gives ur plant SAR/ISR defenses to surface defense (SABF) . I also use biocontrols for my bugs and I stop doing that if no pest pressure occurred. However for mold prevention and keeping SAR high I use regalia to end.

another tip for regalia I didn’t see anyone mention or company doesn’t either is when u add regalia (for drench applications )to your rez and it bubbles/Aerated it will foam over time. so make sure to use whole brew. I have so many times had like under 10% in rez and told myself no way can it foam to top? that stuff is worse than anything I’ve seen and it won’t even do it for hrs, it’s just happened to me multi times because after first time when it was above 50% full rez it foamed all over floor I thought no way 5-10 gl left on bottom would be tht big of a deal. nope lol

Started my sulfur burn for 4.5 hours, how long can I enter my 700 sq foot basement after the timer goes off?? I really don't have any windows to open down there is that a problem?

Also I have a small fan turned on down there, should I changed the position of the fan or will the sulfur spread all over the basement anyways??

Also I think I'm barely smelling the sulfur upstairs MAYBE.. Is smelling it bad or just taking in the fumes?

Not dying from something doesn't mean it's good for you. It may be worse in an indoor-environment, with increased concentration and RH.
I'm not saying it's dangerous, I'm saying better safe than sorry. Sulfurous acid is bad, especially if you smoke it.
Sulfur dioxide on it's own is not the only problem here.

Do you know anything about chemistry? Because it doesn’t sound like it.

It really isn't good to breath it.

Inhalation
Inhalation is the major route of exposure to sulfur dioxide. The odor threshold is 5 times lower than the OSHA PEL (5 ppm). Most exposures are due to air pollution, and this has both short-term and chronic health consequences for people with lung disease. Inhaled sulfur dioxide readily reacts with the moisture of mucous membranes to form sulfurous acid (H2SO3), which is a severe irritant. People with asthma can experience increased airway resistance with sulfur dioxide concentrations of less than 0.1 ppm when exercising. Healthy adults experience increased airway resistance at 5 ppm, sneezing and coughing at 10 ppm, and bronchospasm at 20 ppm. Respiratory protection is required for exposures at or above 20 ppm. Exposures of 50 to 100 ppm may be tolerated for more than 30 to 60 minutes, but higher or longer exposures can cause death from airway obstruction. Sulfur dioxide is heavier than air; thus, exposure in poorly ventilated, enclosed, or low-lying areas can result in asphyxiation.

1. Moles of Sulphur in 1 g = (mass of Sulphur in g/molar mass of Sulphur in g/mol) = (1 g/32.06 g/mol) = 0.0312 mol
2. From the balanced equation, the mole ratio of S to SO2 is 1:1.
3. Therefore, for 0.0312 mol of S, moles of SO2 formed = (1/1) x 0.0312 mol
4. Thus, the mass of SO2 in 0.0312 mol = (moles of SO2 x molar mass of SO2 in g/mol) = (0.0312 mol x 64.058 g/mol) = 1.999 g or approx. 2.0 g
5. Next, let there be 1 m^3 of air and convert this 2.0 g of SO2 to mg/m^3 = (2 g x 1000 mg/g) x 1/1000 L = 2 mg/m^3.
6. Therefore, by formula, the concentration of SO2 in ppm = {24.45 x concentration in mg/m^3}/molar mass of SO2 = (24.45 x 2)/64.058 = 0.76 ppm or approx. 1 ppm
7. According to NIOSH, the recommended airborne exposure limit (REL) is 2 ppm averaged over a 10-hour workshift and 5 ppm, not to be exceeded during any 15-minute work period.”

See that. Another RIU stops posting after committing to a sulfur burn. Nobody listens.

He just needs a good ipm,I had it like three years ago from my outdoor grow then brought clones indoors so started with a light citric acid spray three days later sulfur spray three days later neem spray. I repeated for like two weeks straight and ain’t seen any type of pest since then,of course get your environment in check
