Vehicle Rotor Dust Additive?
    #202747 - 03/04/09 12:46 AM (7 years, 9 months ago)

I recently visited an old friend's farm to collect some of his livestock manure for my compost pile.

This guy grows some amazing outdoor cannabis, and has been doing so longer than I've been alive, so I asked him for any tips that might help me with my crop. He said he always adds some dust from what's shaved off a vehicle's brake rotors when they are turned to his compost pile.

I was wondering if anyone else had heard of this, or even might know what the shavings would provide the plant. I've got another batch of clones that will be ready in a couple of weeks, and I was thinking of giving it a try with one of my outdoor plots. I know this is a long shot, but his results are tough to argue with.

Thanks guys.

No idea but I wouldn't want that shit in my soil...Break rotor/pad dust with dried on fluid...I don't know it's just me. He may just have a green thumb?

i had to look this up.  apparently 90% of brake rotors are cast iron, so adding the shavings to the compost will boost up it's iron content. 

:shrug:  don't know if i would do it, but you say he knows what he's doing.

I don't know what fluids you're referring to. A properly working brake system is a closed system with fluid going to the calipers, not the rotor itself. :shrug:

Thanks for the info. I dug a little deeper and found that rotors are probably ductile cast iron, which like you said, is composed of mainly iron, with trace elements in these percentages: C 3.4%, P 0.1%, Mn 0.4%, Ni 1.0%, Mg 0.06%.

I'm not really sure what you're saying, but I asked the boys at my local AutoZone if I could have some of the rotor dust from their machine, and they were happy to give it to me. I'm going to try some sparingly in a few of my plants soil mix.

Thanks for the help friends, you're always very helpful.:thumbup:

Early brake pads (and linings) contained asbestos. When working on an older car's brakes, care must be taken not to inhale any dust present on the caliper (or drum).

I have always been told to stay away from old brake pads because of asbestos hazards. I don't know about you guys but I wouldn't let that shit within a mile of my organic gold.

But as always, I encourage you to test it out and report back the results!

This is true, but I mean the odds of yours not leaking a little are quite low. The pressure coming out of the calipers is fucking extremely high. I don't know if it's enough to affect anything or not but I'm not finding out.

lol, i came back and red what i typed and it was all fucked up. anyways I was just saying couldnt you clean the oil/whatever fluids are in it. so if it was dust you could stick that stuff in a cloth and cleanse it, or if it is whole, clean it and make your own shavings.

I'd find a cleaner source for cast iron; who knows what the rotors absorbed from the road and exhaust fumes.

hard up for iron!:crazy2: any guesses on how long we'd wait before it was available to the plants?

You're the man, Dr. P. :grin:

I'm not really attempting this with brake PADS, which have been known to contain asbestos, but brake ROTOR shavings, which don't contain asbestos. I figure anything interesting and new like this is worth a shot, whether it works or not. I've learned more from my mycological ventures through mistakes and failures than by my successes.

Thanks to all, and I'll be sure to report back my results.:thumbup:

Brake dust? Seen it all now.

The plants get more then they need from the soil they are in.

It's very easy to creat toxic conditions with iron in the soil when it pretty much isn't needed.

Last if your looking to increase iron in the soil (not needed) there are way better ways to do it.
