    #19495321 - 01/30/14 07:34 AM (10 years, 11 months ago)

do it yourself man. its really pretty easy. those prepours are expensive. all depends on how the plates are prepared concerning contam issues...have fun... agar is the only way to go in my opinion...:mushroom2:

Others can feel free to disagree with me but my first box of agar powder included sugar in the ingredients.  I think this can hose up the performance of the agar.  I recommend getting straight up agar with nothing else added.

yep, don't get the kind with sugar in it. prob work with plain agar. you can add nutes such as instant potatoe flakes, honey or light corn syrup, malt extract, yeast, ect... the myc gets lazy if you add too many nutes. it grows faster with low nutes, searching for food....:smile:or if you have the expenible cash. get the prepours for ease for your first try...I,m a cheapass so I make my own...:wink:

Pre-poured dishes are clean, sometimes even contain antibiotics to help your business, but yes, they are quite expensive.

With home made dishes you can stay cheap even if you screw up and have contamination rates like 50%.

Also, you can do agar in a SAB and have reasonable success rate. With a decent technique you can approach 100% while staying low-tech.

Unfortunately agar is very unforgiving. One wrong move can cause MOST of your plates to show quite colourful growths in days. :smile: It can be frustrating, but worth it.

Colonizing agar plates a beautiful, and great tools to get pure cultures, stable yields, to identify and work around small contaminations.

Always stay as clear as possible. Constantly revise your technique. Always think ahead, be quick, and reflect afterwards: did I do it right? Where could be any crew-ups? How could I avoid those situations next time?

I think agar is awesome.

Good luck! :smile:

Yeah i was thinking because its my first go with agar to buy pre poured so I dont fuck it up.
but they also have one that comes w the powder dishes and swabs for 20 or 30 so I might do that.

This is what i was thinking I would do.
Take a nice cap.
make a spore print .
Colonize agar w print.
Move agar to jars.
and well you know the rest.

Again I'm a novice so I may be wrong here, but I believe it's "better" to colonize using a biopsy from a nice fruit with good traits vs. spores.  You want to work with good genetics.

Mushrooms tend to mutate quite quickly.

If you clone too much, their genetics mutate to a point where the vigor of the strain will be lost and yield and/or potency will be diminished. Susceptibility to infections will grow, as colonization times increase. This is called senescence.

Because of the quick mutations, spores from a single fruit can show sometimes surprising genetic variety. This is why growing multispore cultures said to be like gambling. Mostly average, sometimes bad, sometimes great.

If I wanted to select for certain traits, I's grow dozens if not hundreds of MS bags and search for that trait.

If you find the perfect strain, you can always clone the life out of it - quite literally.
