Physan is in fact awesome shit, but it's not approved for use on produce for consumption ( with the exception of tree fruits, and then only allowed by local law in a few states in the US- you folks do wash fruit before you eat it, right? ( Remarkable how much $ the WA Apple Growers Association has to throw around).

That being said, I've never heard of any health problems from the stuff, and I've been around a lot of it. Almost assuredly safer than smoking, say, Floramite- and you'd be hard pressed to find mid-grade commercial indoor that hasn't been hit w/ Floramite, so I'm gonna say no more dangerous than normal.

Phytotoxicity may be more of an issue, but you should always test that for yourself.

I dunno- I'd hate to see folks using Physan as a fix for ventilation problems. I don't think it's gonna hurt anybody ( well- don't spray yer eyes) but I don't really think of it as a "first-line" treatment- I'd hold it back for real issues.

It is, though, the very best thing ever for sterilizing surfaces ( like everything in the room) between crops, and I've seen it work wonders on powdery mildew in rose houses ( our local rose grower uses a 55 g drum every winter- just never eaten ( or smoked) any that I know of. Odds are, though, that I've eaten and smoked a bunch that I didn't know of...(cough).

I didn't say it shouldn't be used- I just hope folks read the labeling ( including msds) before they start throwing it around.

And please please please be careful about how you dispose of any excess- this stuff'll kill a septic system dead.

My child was born w/ psychic powers- she somehow knows when I'm just about to lose it and vanishes, only to re-appear when I've calmed down. Quite remarkable really.
rhizome Reviewed by rhizome on . Preventing Powdery Mildew I have a particular strain of mj that is a Master x Bubba hybrid. It's a really potent strain that I really like. The only problem is, it's highly susceptible to powdery mildew. I have six different strains of mother plants growing together in the mother cab. The MxB will get covered with powdery mildew while all the plants around it have none. I'm a couple weeks into veg on some plants that were cloned from the mother and I noticed yesterday that the leaves have a slightly dull patina to them Rating: 5
