Old bed
designs
Everything imaginable has been
used as earthworm beds/bins, from old
refrigerators to
large windrows, from coffee cans to wash tubs.
The one common denominator was
that none of them could be separated easily or
effectively. They were all hard on the earthworms and the
growers backs!
The most popular means of
separating the earthworms from their bedding
(vermicompost) has always been to haul the casting out
into the sun, put it on a large table and wait until the
earthworms are stressed enough to crawl to the bottom of
the pile, then slowly scrap off the bedding (with the egg
capsules in it, they don't CRAWL yet) and then use/sell
the resulting vermicompost, complete with egg capsules
(6-10 babies in each!) But, if it was cold, wet weather,
what then. Haul everything indoors under a light, lots of
hauling, from the bed to the table, from the table back
to the bed.
Another popular method was to
let one end dry out and not feed it. The worms will crowd
into the the damp end and the other half can be removed.
This left one end of the bed Non productive for long
periods of time, besides stressing the earthworms, by
over crowding them. So, a 8' long bed was only producing
one half as much, in twice the space!
The past separating methods
work fine, IF you are selling, harvesting the earthworms.
But, if you want the vermicompost it can be a very
unsuccessful operation.
The past beds/bins were usually
put outdoors, where they were subjected to the weather, pests and the earthworms had a tendency to
run away, when they didn't like their new homes.
Production was markedly reduced.
The bed/bins were usually put
on the ground, so a lot of bending over and shoveling was
necessary to work them and remove the bedding. Poor
growers back!
They were usually made out of
wood, which didn't last long and had to be replaced as
and when it rotted.
Some people dug
"pits" into the ground and when it rained they
flooded and there went their earthworms.
Anyway, after investigating and
trying some/most of the above bed/bin designs I finally
sat down and designed AVSA. I designed it to conserve
floor space, which justifies the use of indoor floor
space.
I designed it to be separated
quickly, easily and efficiently. Without the bending over
shoveling, the added man hours and the sore backs.
I designed AVSA to turn the
vermicomposting business into a Profitable business
instead of a back breaking, partially profitable hobby.
Now with AVSA the vermicompost
is the product being produced, and the earthworms are
finally the producers of it. Instead of the earthworms
being the product being sold.
A quick glance at the other
websites and the construction of their beds/bins will
tell the story. A back is a terrible thing to lose, as is
a bunch of over-stressed earthworms.
