Inherited worm-farm and its garden!

Hello all,I have just inherited a neglected French-design worm farm, and am in need of a little advice.I lifted the lid for the first time on the worm farm and understand it had been left untouched for a month or two, so I expected I would find a worm graveyard, but to my astonishment (and joy) there was still lots of movement and wriggling at my introducing light.Also, the bottom of the three layers in the worm farm (having slid it out for a quick look) is a perfect worm-cast block. Very…See More

Hello, I am new to the site and just wanted to introduce myself.I have been vermicomposting for a couple of years now.I use mainly Eisenia andrei and have built up quite an extensive population.I also have small populations of Dendrobaena veneta, Dendrobaena hortensis and Eisenia fetida.My interest in vermicomposting led to me learning how to identify earthworms under the microscope and I occasionally go out to various locations to sample, identify and record earthworms.I have a website on…See More

Hi to allI've been keeping a worm city for two years but got fed up having to set aside an afternoon to harvest castings only to find the lower layer soggy and full of worms I could not get out.Probably my own fault for not enough bedding and also it would let rain down the sides so the more converted trays would get the wettest.So now, with thanks to this forum and the designs on here as well as Brian the Worm Man I have butchered one of my wheelie bins to make a flow through in the hope once…See More

At last I have managed to add photos taken as the work progressed. 

The final gap between the rods was 3 inches, with the rods being 1/2 inch diameter, the pitch centres being then 3&1/2 inches. 

I am not conversant with the method of fitting my photos into the text and so they appear under 'Photos' and are dated: 21 March 2017, by clicking the single picture, access then shows the series of 12 pictures.

Please be free to send me any queries and suggestions, for…

I will say that previously the bedding used in my wormeries was from a collection of Autumn leaves.  Although leaves suited the worms I found that there was a continuing build up of slugs, due to having collected the leaves from earth beneath the trees? . I would later see upon inspection, clusters of slugs eggs so a bigger population was then likely! 

Perhaps leaves from a paved/concreted area would get over this problem? (Any comments?)

Hessian sacking I found worked well if…

,Time has gone by since my last blog and here is a further development. I had mentioned the ventilator in the lid previously.  I am aware that numerous members state that due to using a feed through system they do not have to collect exudate as is the case of a stacked tray system.  I found that over time quite a lot of liquid had drained into the containers below (three flower troughs).  Further, on opening the lid there were always a number of worms either on the walls or adjacent to the…

Modular Insulated Feed Through System

Here I will mention that previously I had only to raise the lid and note the number of worms coming to the top of the chamber.  This would then allow me to consider what may be the cause of their trouble.  I had for a number of days lifted the lid and there seemed no problem in this direction,

I began to be aware of a slight smell within the garage, a few more days and this became more powerful!   I found the source of the smell: a large number of worms were found shrivelled in the…

Modular Insulated Feed Through System

Before I begin I want to say that as a previous novice I found that references to bedding somewhat baffling.  The reason was that no distinction was made between the bedding used in starting off a wormery and that used to cover the wormery contents.  Perhaps the prefix of lower and top might be used to avoid any confusion?  Please feel free to comment.

More of my MK4 experiences:

As I previously stated when the worms are not happy they begin to rise up the inner walls, their…

Modular Insulated Feed Through System Problem

The moist atmosphere within the cabinet had been overlooked.

The opening for the ventilator in the lid, which is partly of steel, began to rust.  The rust was cleaned up and car underseal applied.

Non of the worms were found to have suffered!

Modular Insulated Feed Through System

Here I wish to explain my MK4 wormery.  The main chamber of which is the insulated cabinet.  I was looking for a deep freezer cabinet, a fridge would have had fittings for milk bottles!.  The one I found was approx. a 2ft cube...The back was cut out by using a Stanley pad saw from inside the cabinet. (It was a Necht N1 that had been dumped minus the compressor).  That done I made a wooden frame to take the rods, the cabinet now sits on the frame which is 1 1/4in wide all round. The door now…

In the begining

I am awaiting my worm's arrival. I have prepared shredded paper and gathered kitchen scraps. I have a container of baked and powdered egg shells. I am just about ready.

However, I look at my bin which is a 2x3 tank 18" deep and wonder if I want to drill holes in the bottom. I have heard that they are not actually necessary but so many people are doing it. For now I am going to bypass this step.
