Vermicast-Can I leave in room temperature for a couple of days? 

Vermicast aka earth worm pee

-Can I leave in room temperature for a couple of days?

- I've got a worm farm from the Warehouse ($40 for two containers). It's recommended to apply a liter of water every week because the a worm's pee is no good for another worm (maybe toxic?). So Is there any harm of applying it concentrate (i.e., 1 L for 20 fruit plants)?

Re: Vermicast-Can I leave in room temperature for a couple of days? 

I leave mine bottled up for way longer than a couple of days, sometimes it takes a couple of weeks before I get around to using it as I've only got a small garden. It never seems to do any harm to the plants. It never occured to me that it might not be good to leave it sitting around.

I don't apply it concentrate because all the guides say not to.

Vermicast is the worm castings or poo - the wees is worm juice/wees.
You can leave it at room temp for a couple of days providing that's not very hot. The more important issue is sunlight - it's best kept in a cool, dark place for longer useful life. You can apply it undiluted without damage but why do that when 10:1 will do just as much good for your plants?
I suggest you don't tip water through your worm farm every week. Container-style farms like your tend to get too moist and solid, needing aeration rather than more fluid. In my experience, one worm's pee is as good as the next rather than being toxic.

Very useful info. I thought that leaving the vermicast out for many days would make it loose all of its nutrients. I agree with the less water theory because in fact I have to turn the farm over every now and then because it's too moist. Cheers.

I kept the water content of my worm farm down by adding ripped up cardboard on a regular basis. This seemed to make the whole process work better.

Thought you might be interested in some of the research:
1. Worms don't pee or wee. You are talking about leachate. Wormfarm leachate will contain rotting material and may not be pathogen free. I would be hesitant about using it as a foliar feed on my leafy edibles (e.g. lettuce etc.).
2. The research shows that there are no benefits in high concentrations. Low is best. 1:10 is much higher than necessary, though this does depend on application rate. Using it at 1:100 - 1:80 will produce as good if not better results - especially if applied regularly (i.e. weekly - fortnightly).
3. Wormguy is correct about sunlight. Keep it in the dark as the natural growth hormones (e.g. auxins) which are produced by humic/microbe activity in vermicomposting will be destroyed. However the nutrients will not be. He's also right about moisture. Optimum moisture for a worm farm is about 85%. Best operation should produce no leachate. He is wrong however about one leachate being as good as the next. Different raw material vermicasts perform differently (all still better than chem fertilisers though).
4. The key to vermicasts is the humics. They (a) feed soil beneficial microbes, (b) act as a slow release fertiliser in the soil, (c) have been shown to have pest resistance and suppression properties, (d) make plant nutrients more plant available.
