Worm tea for Orchids

[TyronSA]

Oky so i have bought this Worm farm that produces worm tea. My problem is im not sure how to actually produce this worm tea. Basically what it is is water drained through compost with worms in it..

Now what i dont completely understand is how long do i wait for the compost to be ready to be flushed with water or do i just leave it moist. Some people say Leave it like that just pour a little bit of water over the surface every now and then and leave it to drip into a jar. What they ment by that is to not flush it. Other people say you need to flush it with about 5liters of water every 3 weeks or so.. Its all a bit confusing to me. Can anyone give some advice to follow? I would like to see what this Worm tea does to the orchids. Apparently it is a all round GREAT fertilizer for anything.
