My worm farm is in the carport and so is sheltered from rain. I was just wondering how much "wee" would normally be produced. The environment is moist for the worms as in damp sponge level of damp. and I have a some wee in the base but not enough to be able to drain off using the tap in the base. It has been running for about a month.
It is not a problem, more just out interest.
Do you add any water to your worm farm? You don't get a lot of juice from the food you give them. I keep a thick layer of newspaper over the top of the food in the worm farm, otherwise I get maggots in there. I make sure the newspaper stays damp, and approximately every one to two weeks I pour 2L of water over the newspaper slowly. Every couple of months I do about 5L. It washes extra goodness out of the castings and it doesn't bother the worms as it is kind of like a heavy downpour. It also helps dilute the worm wee, so you don't have to dilute it so much after.
I also keep bricks under one side of my worm farm so it is on an angle towards the tap, just to help it along. I leave a watering can under the tap and leave the tap open.
I'm not sure if I answered your question but I hope this helps.
