Liquid germination of spores?

[Bigbertha]

Hi all,
       i heard of a way to germinate spores using liquid media rather 
than agar-agar plates.  The guy who explained it to me said that using 
this technique i would dramatically reduce the colonisation time on 
grain media. 

1- Germinate the spores in 3/4 of a mason jar using 89% water, 10% malt 
and       1% yeast.

2- Make sure you have sufficent air in the mason jar (1/4).

3- Give a generous shake to that jar 2-3 times daily. Make sure to shake 
the jar at least 1 minute this should be sufficent for the spores get 
their oxygen from that shaking.

4- Between each shake, store the jar on it's side rather than lid UP, in 
a relatively warm place.

5- Do this for a week or so. That should give the spores more than enuff 
time to germinate. Prepare the grain media and pour 10% of content 
(Liquid media) over grain media. Distributed evenly, one jar of liquid 
media should innoculate 10 grain filled mason jars. This is of course, 
if you use same size Mason jars during the whole process.

Here's what that guy told me. Feel free to try it but please i would 
like to have more information and reply from people who had experiences 
with a similar technique.
