I think i got interested in worms about 20 years ago (late 1980's)when i went to a worm seminar in Adelaide. It looked at medium scale worm farming for profit. If i remember correctly it was a scheme where you paid a sum of money, They help you to get set up and offer advise and then you can sell your worms back the same man. It wasn't really an option for me at the time, but it did spark an interest which has been on going ever since.
My first worms came about 15years ago (early 1990's)when i bought a Reln Worm Factory. I loved that thing. I read the little instruction book from cover to cover several times (no Internet back then). It did work, in that the worms did multiply but i never really progressed to get that top tray on and working. and i never did any harvesting of castings either. I felt the bottom tray was always full of precious worms i couldn't harvest.
I kept them out the back under the verandah and one hot night i went out to check on them and found they were in the process of vacating. No kidding they were every where up the walls on the ground, everywhere. It was just too hot in there. That's also when i realised i had too many in there its a wonder they could even breath. I dint know why i just didn't buy another one. Probably because i still hadn't got anything out of the first one yet.
I also lost the lot one time by putting the food over the entire surface area and that caused it to heat up as well.
I leave it a few years, (late 1990's)pull the thing out of the shed, scrub it up a bit. Start again, this time i lose interest and let the thing dry out... hummm....no worms again. I think i did that twice.
We moved to Queensland in 2005 and in 2008 i try again. Pretty determined this time. I buy one of those big worm farms this time, with the little sliding doors at the bottom to get the castings out. The 2000 worms i buy from Bunnings are really slow to start. My initial bedding is not deep enough. Every time i try to get some castings, I pull out worms as well.
I decide i need to go bigger, more worms equals more food consumed and more castings produced. A Christmas holiday project 2008 sees me buying four big fishing tubs, I drill holes, install taps ect. I have new knowledge now from the Internet. I order 8000 juvenile worms 1.2kg from Kizan worms online and now i dreaming of being a weekend worm farmer, with the worms themselves being the main product.
Today i harvested 2kg of worms for a new bed, i have two big tubs of castings set aside to hatch cocoons and then finally ...i have my first castings. And guess what? plenty more where that came from .......I have a long way to go. but stay tuned and we'll see.
