Just trying to get this moved down, I'm guessing it stays at the top until there's a response so, hopefully this moves it on down.

I want to purchase about 3 metric ton of earthworm. please advice.

Wing Onn, Are you planning on opening a worm farm in Malaysia? 3 tons is a lot of worms to handle.

Sorry lee wing onn, nothing I'm experienced with I purchased a couple pounds. HappyDRanch sells 100 lbs of worms for $1250.00 US Dollars, along with enough bedding for them and books & videos on turning it into a business. That's $12.50/lb which is a very good price when you consider 1 lb of worms costs $30, and 2 lbs costs $40.

3 tons of worms will require at least a ton of food scraps a day, probably 2 tons. I think you need a company that deals with worm consulting and handles equipment that can maintain that many worms.

Annie,Yes I intend to start up a worm farm

Hello
Tell me how do you examine the difference in charactertics of purebred E. fetida and other earthworms. Hopefully you won't mind telling me in details!
I am expecting the arrival of 1/4 lb E. fetida in 1-2 days. If it turns out not purebred, I might get rid of it as well.

3 metric ton is a huge amount.Recently I bought 2kg of worms and I'm poorer by RM400. Your 3 metric ton will cost you more than half a million ringgit!! Still interested?

Properly managed- 100# would theoretically turn into about 3 metric tons in a year. That's perfect, theoretical, and the word of a guy that killed the worms in his bin.

Supposedly you can double them every 2 months.

200# in 2 months
400# in 4 months
800# in 6 months
1,600# in 8 months
3200# in 10 months
6,400# (approx. 3 metric ton) in 12 months

An article I read on a commercial vermicomposting operation showed that they acheived this sort of doubling, or better, in the first year to get up their stock for the operation.

BTW- at about $20/#, 6000 pounds of worms would cost about $120K. Simple economics says that you should be able to buy them a lot cheaper in that sort of bulk, but you need to 1) find a source that can provide that much, and 2) find a source that would not feel that you were going to be such competition that they were selling the start of their end, if you get me. For that reason, for the simple economics of laying out $100k+, and to get the bugs worked out in the feeding, breeding, housing, etc of the new tennants- I think that starting with a 100# seed population and breeding up would probably be a better way to go.

Again- this is the useless opinion of a chemist that killed his worms, but can't keep his mouth shut :)

Thanks for posting all of this great info. Just set up a worm composters here in washington dc, so any information is helpful as I am trying to get them healthy and breeding! I'll be documenting my progress on my blog.
