Hi Nic,

Ok, I get it.
Well I sort off accidentally bought 2 indoor bin-sets, 4 tray version...
Had them send from UK to the Netherlands......
And told my wife ( sweat sweat )
Oh, ok , she says....

Ok, so does she want a huge xmas present herself????

Anyways,
maybe you have read it, I have a big compost bin outside.
It now has about 1 metric ton of plant material.
I put in 2 pounds of worms, not a lot, but hoping to have more of them by spring time. In about 4 months time, spring has arrived, and hoping to have good compost and great worms!

i hate to wait though...

Cheers Bart

I just started a blog which includes pictures and text about my OSCR bin. I modified it a bit as explained. It's not complete yet but I hope to keep adding to it. It's at www.vermitec.com/wordpress.

no..... my mom says to stick w/ the worms for now, and see if i cant kill them( we tried fish and i gave up at 20: time elasped- 1 month). plus, i've asked for a really expensive thing for christmas, so i'll probably have to buy it on my own. i just got another 2 pounds of worms put into my first bin, and they aren't making a mass escape, so i think i'm doing something right. in other words, i'm working on it (:

Hi NIc,

Me and others seemed to have fallen asleep.

Got any further on the bokashi?

Cheers Bart

i'm Nic. did my 9th grade science fair project on vermicomposting, and just ended it. my mom makes me keep my worms in the backyard. looking into bokashi for meat waste and stuff like that.

Hi Bentley,

Hmm, I thought the beds were already having worms in them.
It is funny to get weird stuff popping up in un expected places yes,
however..

I should be a bit carefull with the seeds.
I have a big garden and am growing historic "forgotten"fruits and vedgies. Heirloom?
So I have to keep weeds out as much as possible.

I do want to use my compost though.

So my plan was to make a 2 bin system.
One to get it to the boil, and the other to finish things off.
The last one would be perfect for the worms.
However, as I just started making compost there, I just did not have enough.

The food is the product of anaerobic processing, gotten brown, then turned a couple of times.
In this stuff I made a H form gutter 4*4 Inch, and put worms and bedding materiel in that H. Then covered with an other 2 Inch of brown compost.
There is no stuff in it, that can heat up again, so no worries there.

So, just the top would be heating up, and maybe not enough. Will check tomorrow.
It will keep it warm enough trough winter though ( I hope )

Will make a few pics tomorrow, ith the rain is not too bad.

Cheers Bart

Hi Bart,
I probably view the term "problem" with a slightly perspective than some at times - and weed seeds is definitely one of those times. In all honesty, I am really mellow and laid back about this sort of thing. I constantly have little plants popping up here and there in the material that comes from my various systems. It almost makes it more interesting.
Down in my basement right now there are open tray systems that have lots of tomatoes, cantaloupe/melons, even a sprig of kale popping up. Kinda entertaining :-)

This is my first year with the winter windrow approach (so no 'finished' pictures yet). My first winter composting system was simply an insulated wooden bin. Last year, as mentioned, I had a big bed with straw bale walls.

Material from my various beds tends to get moved around a fair bit and I am sure that's what will happen next spring. Almost certainly I will rake everything out and concentrate it over top of my vermicomposting trenches where worms will finish processing the material.

Your buffer zone may do the trick for you assuming it doesn't heat up too much as well (you mentioned it having lots of "food" - just keep in mind it is generally the stuff we think of as "food" that helps to kickstart heating). Generally when people pre-compost (and this IS quite common) they do so in a separate system before adding the material to the worm beds.

Anyway - best of luck, and do keep us posted!

HI Bentley,

So don't you have problems with the seeds?

I almost have a feet of buffer under the big bin, so I hope the worms will keep in this buffer area until the heat has gone in the layers above a bit.
In that buffer zone is enough food for about 4-6 weeks.

I really need to get rid of the seeds in the compost, as I dump all my unwanted weeds there, with seeds and flowers and all.

Do you have any pictures from when the windrows are done?
I mean, what do you do when winter is gone, do you collect the worms and the castings?

Cheers Bart

Hey Bart,
I certainly HOPE it won't get that hot! There are a lot of worms in that bed.
This is why I am adding materials slowly over time. By the time it is at its max height the serious winter weather will be here. My aim is to keep it as close as possible to 20 C (68 F) all winter. We shall see :-)

HI All,

Daft, I had been reading Bentley's winter composting blogpost weeks ago.
And I didn't add things up.
Been running around too much.

Bentley, those windrows, do they get hot enough to kill weed seeds?

Cheers Bart
