Worm Farms

Buying a Worm Farm

I have decided to get a worm farm to help reduce the amount of waste that I throw away. This article describes why I chose to buy a worm farm and the research that I have done into the subject of worm farms

Why choose a worm farm?

Everyone knows that recycling waste is environmentally sound, and we even have a green cycle bin that takes away all organic matter (e.g. kitchen waste and garden waste). We also have recycling for plastic, glass and metal. However I'd like to go one step further!

Although recycling waste via your county council is a very good thing to do it still involves buying a great big truck and burning lots of diesel as it chugs its way around the houses, and there is still a lot of industrial processing required to turn the waste into compost. By recycling as much waste as possible without someone having to take it away I hope that I can do my bit in cutting down on fossil fuel usage.

And more importantly worm farms sound like they could be fun!

But why a worm farm, and not a compost bin?

I chose to go for a worm farm rather than a normal compost bin for several reasons

Choosing a worm farm

Before buying a worm farm I did a little research on the web. There appear to be several types of worm farm that you can buy. They are detailed below:

Continuous Flow Worm Farms

These are pretty big and industrial worm farms. The waste goes in the top and eventually comes out the bottom (using some sort of griddle system) as compost. These worm farms seem to be the most effective, but they do take up a lot of space and are pretty expensive

Stacking Worm Farms

Stacking Worm farms have several identical boxes stacked on top of each other. The idea is that you fill up the bottom layer with food and worms and then gradually fill up the upper stacking boxes whilst the worms are munching through the food at the bottom. Once they have turned all the food in the bottom tray to compost the worms will move on up to the next layer. You can than take out the bottom tray, harvest the worm compost (called worm cast) and put the now empty container on the top ready to fill up with more worm food.

Single Bucket Worm Farms

These are very simplistic devices often consisting of a converted dustbin or similar. They have special inserts to allow for good drainage, aeration and generally are made a nice place for worms to live. The worm food just gets piled into the top of the bin and the worms eat their way through it. When you want to harvest the worm compost you have to remove the top layer of food (which should contain most of the worms) and then remove the compost. Usually you will have to sort through the compost to remove any remaining worms

Build your own Worm Farms

There are plenty of ways to make you own worm farm, all three types described above can be easily put together with a bit of thought and some common DIY materials. I thought about making a Stacking Worm Farm using some plastic stackable boxes that are designed to slide under beds. In the end I decided to go the low hassle route of buying an off the shelf worm farm, but don't let that deter you! A quick check of Ebay showed that there were people selling their own worm farm efforts. Quite often they looked like a wheelie bin with a few holes drilled in the bottom, so beware of what you are buying.

What worm farm did I chose?

Eventually I decided to go for a Stacking Worm Farm as it seemed the best compromise between size and ease of harvesting the worm compost. I went for the "Can-o-worms" device which can be found at all good worm shops. It was pretty pricey (�90) but included all the things I needed to get started, including the worms, some bedding mat, lime (needed to regulate the pH of the compost) and "worm treat". I'm not sure what Worm Treat is but I'm sure the worms will love it!!

Does the Worm Farm Work well?

My worm farm is arriving sometime next week so I will update this worm blog with more information as I get it. I'm stockpiling my kitchen waste in preparation for its arrival and am already amazed at home much stuff we throw away, I have a small bin full ready for our little worm friends to digest.

Due to the number of comments on this page/topic we have moved further discussion to the forum.

"My son would like to start a worm farm but we live in the North East of the US where temps get below freezing. Is there a way to keep the farm outside in the very cold nights? My wife and I are not keen on having it inside."

"How is the farm coming along? I am thinking about getting one, I have a largish garden but the compost pile seems to be taking a long time and there have been a few unwelcome visitors in the shape of rats, so thinking of heading down the worm farm track. Is it a good investment?"

"It really depends on what is in there and how the worms are doing. My worms really have slowed down since it got cold. However I would estimate about a month per tray if the worms are hungry and the box below is pretty well digested."

"How long does it generally take before you have to change to the next box?"

"Does it really matter what kind of worms I get? Are there many different kinds of red worms? "

"HI Rachael I too read about cooked eggs shells and stuff that is bad for the worms. But I just chuck everything in and they get along fine (I crush the raw egg shells first however). My worms get fed onion, lemons, oranges, all the tea bags and all the coffee! All the things they say might be bad. They dont seem to mind..."

"Hello again, I had another question... while researching about wormfarms... I came across a website that suggested that I only used cooked eggshells. Is that true? And also i heard that tea bags and coffee grounds aren't good for my worm farm. I've heard from other sources that it's ok for my worm farm. So I'm not sure what to believe here."

"Hi Rachel In the summer months I have noticed that the worms get a little upset when it is very hot. They burrow to the bottom trying to get out of the heat I think. I put a damp old towel over the farm in the heat of the day. Likewise in winter they seem to move to the middle of the farm, trying to keep warm. Last winter I moved them into my little garden shed which I think kept them a little warmer. But overall they are resilient little chaps! "

"I'm interested in worm farms... but wondering if I must keep my worms inside or if they can handle the winter temperatures that can drop below zero? And is it okay to leave them in a sunny area if they are covered?"

"HI, thanks for the feednack comments. To answer both your questions I kept the worm farm outside just tucked near a small bush. This offers the worms some shade from the heat and shelter from the rain. However they seem pretty tough and can withstand the elements. I have also found they tend to speed up if you give them coffee beans :-)"

"Hello, Thankyou for writing about worm farms....I've only just started researching them! I thought worm farms had to be kept indoors or at least under cover or am I completely misinformed?"

"What a great article! My mum rang me today to ask if i wanted a worm farm, and i found this site whilst googling for them :-) She suggested the stacking one as well. Only thing i am concerned about is they should be kept in shade, and our garden is very sunny. I'll find somewhere. Anyway, worm farms sound like they could be fun! ;-)"
