GWN wrote:Hi there, so glad you finally found out what was causing your problems.
I have recently recovered from an advanced cancer treated with chemo and radiation.
In looking back a what could have possibly caused it (I am a health freak and long distance runner), I am convinced that all these artificial chemicals play a part. WHere I was living I knew of 3 women on one road who died of ovarian cancer. I was living in a heavy farming area where many herbicides were used. We were all on wells....
Why is it that nowadays everyone seems to have cancer?
So this is why I am gardening to beat the band. So I know where everything comes from. We have built all of our raised beds with white cedar that we had milled when we built our house. (all the trees that had to be cut down)
This year I have ordered quinoia seeds and am going to attempt to grow it and then make bread with it.


Janet,

Thank you for the kind words. I like meeting someone who gets it. I hope you like it here.
Sorry it took so long to reply. Threads sometimes get by me. sawing logs

You have written a stunning personal account. Thank you for sharing. I hope you continue to feel better. So many ways to be contaminated between skin absorption, breathing, eating, and drinking. Not knowing at what point the body becomes hyper-sensitized, or if damages can be reversed or not. Blah. After reading your post I paused and changed my mind about lining my next box with plastic. Not doing it. I’m not convinced a healthy plastic exists. Think I’d rather spend a nice day emptying (good exercise too) a deteriorated box and refilling a new one without plastic for peace of mind.
Keep feeling better and Thanks!

And thank you! I hope this saves at least one person some pain and illness.

Lining Boxees with Polyurethane Spray? - Page 2 Empty You don't need it, just spending more money

Post  CharlesB 1/22/2012, 5:12 am

The wood in the beds will last for many years even if completely untreated. I made mine out of Douglas Fir because it is what is available and cheap. Not much cedar available where I live.

Here is a video by John Kohler where he shows what kind of state his Douglas Fir beds are in after about 7 years:

Sure the inside will degrade but it isn't like they will fall apart. The UV the outside of the beds are exposed to is sufficient for preservation.

Don't you just love that John Kohler? So much energy and enthusiasm. So many videos!

The only wood I've had rot on me was stuff that was buried in the ground. That went fast, 2-3 years. Above ground, no problems. I have D. fir, too.

I wonder if ... when the wood DOES rot, if you just built the next box on the outside of the first
That way you would be taking advantage of the rotting wood, and keeping all that soil that you have created, untouched.
Mind you, you might end up with a teensy weensy bit bigger square..... though

GWN,
I would have a problem with the hardware cloth bottom that was on the original box. As the first box deteriorated it would leave a perfect entrance for vermin who would do this after they filled their tummies off of my good efforts

I'm not sure which brand you were looking at, but I just picked a random few and checked their MSDSs (material safety data sheet - all products sold in the US have one and anyone selling it can give you a copy). Most all polyurethane sprays contains isocyanate and a bunch of other nasties which are sensitizers, carcinogens, etc. From the toxicology data on the sheets, it looks like tumors are shown to form (in proxy lab animals) at concentrations as low as 6.3 mg/kg (that's 6.3 milligrams of isocyanate to 1 kilogram of you). Generally, that isn't an exposure scenario I would allow in our manufacturing plant (I get the joy of screening incoming chemicals). I definitely wouldn't want it where I was growing my food. If there was a particular brand you were wondering about, I'd be happy to take a look.
