Good disinfectant to clean grow room/tent

[Renfro]

It's actually extremely concentrated. It's totally safe for plants, if diluted properly it can even be sprayed on them. It's pretty awesome stuff.

How strong of mixture is necessary of h2o2 for foliar spraying and also disinfecting room and accessories?

i use it, a quart bottle has lasted me three years. i spray it on the walls, ceiling and floor, at 20%, wipe it all off, then spray it again and allow it to dry. haven't seen pm or bud rot once in three years....

Haven't looked at the data sheet on it yet. Any concerns over toxicity or contamination?

 

[Roger A. Shrubber]

it's not good to breath in or to soak in. i've gotten it on myself and just washed it off, never got any irritation or anything. i spray it, allow it a couple of minutes to settle, and have never had any problems with it.
i used it on a couple of seedlings that had pm when i first started using it, and it fucked them up pretty good, but i used it way too strong. at about a 5% solution, it will kill anything on clones or seedlings without doing any damage to them. they use it to sterilize orchid cuttings all the time, they're apparently a lot more resistant to it, especially when they're mature.
it's commomly used in commercial greenhouses, even in operating theaters.

they won't hurt, but you need something more to really disinfect. use one of those to wipe thing up, then spray a 20% solution of bleach water and allow it to dry...that'll actually sterilize the area. there just isn't enough moisture in those wipes, the residue they leave behind is weak and dries out too fast

I use straight bleach, and do the floors and walls lightly. Run exhaust fans for a few hours, and in a few hours, you're good to go.

 

[Roger A. Shrubber]

that's very corrosive, the chlorine mist formed as the bleach dries is a strong oxidizer...most non stainless metal in the vicinity will slowly corrode, a little more each time. also bad for many kinds of plastic, will make it brittle, easy to snap

Debating physan vs bleach when it comes to toxicity, try handling bleach that isn't diluted like it is when it's bought at the store.

I liked this statement from their site:

"...Physan 20 leaves no harmful residue if foliage is dried and smoked."

 

[Roger A. Shrubber]

i'm not sure i'd try that. but then again, i don't have to. i haven't had any p.m. or botrytis to deal with since i started using it, so no need to expose plants to it directly

3% foliar with h202 is USUALLY good but check on an individual leaf first and NEVER with the lights on.

I'd rather use a sulfur burner for pwm though since it treats the entire grow space and the plants all at once.

Where did you see that?

It has this right on the label:
"NOT INTENDED FOR USE IN DOMESTIC GREENHOUSES WHERE FOOD CROPS ARE GROWN."

it'll kill some but not all bacteria. it kills bacteria that cause odors, so it makes your laundry smell good. it does not kill Staph and some other dangerous bacteria.

 

[Roger A. Shrubber]

sure does say that....i still wouldn't recommend it, but i have no problems smoking a plant that was exposed to it in veg....

Heck the Physan kills Viruses, Algae, Fungus and bacteria. Like @Roger A. Shrubber said, I have no problems with it in veg and to clean a room that doesn't even have plants in it. But to each their own.
