sterilitiy is the key you're right... but if you can grow weed, you can grow shrooms.
the easy shit is as simple as mixing a birthday cake... try it, but if you do... dont rush through
when i didnt have a glove box i would do the innoculations in a bathroom with still air... spray lysol and other things in the room (and then wait 15 min) as well as wipe down all counter tops with alcohol... wore a hair net, gloves, took a shower before and wore a clean white shirt that had the shit cloroxed out of it. and still flame sterilized my needles and wiped off the needles with alcohol....as well as use a NEW sterile needle on each syringe each time... not sure how other people do it but i have had good results.. takes a little longer and a little more thaught but you will be glad when 3 weeks later all your jars are white and not green.
as for start up cost... when i FIRST started i ordered 3 syringes (i think it was like $50 shipped) and me and 2 friends went to walmart and got 3-4 cases of jars ($12 a case) my friend baught a PCer for $60 and we got the brown rice at a organic food store ($15 for 2-3 bags) and made our own flour with a coffee grinder. got the vermiculite from the gardening section at walmart (more then we needed for $15) and some rubber made tubs (i think 5 of them for $10 a peice)
im pretty sure we did 48 jars on the first run and when it was all done with we each got 2oz+ dried (6oz on the first flush) and the second flush we each got around an oz
so 9oz on 48 jars? 5g per jar.... and that was without a glovebox, incubator, didnt do a drunk and roll (a simple step to increase yeild, and do more flushes)
yea it might be hard for some people to get the sterile part down.. but its so cheap to do more jars... and you can do new jars every 2-3 weeks.... if you mess up a marijuana plant you have to do MONTHS of work over.
even in the most unsterile rushed environments.. iv still always had ver 50% colonization as long as the jars were pressure cooked right.
maybe i just think its easy?
id love to see some mushroom grows on here...
Jr.
EDIT: PF (proffessor fanaticus) method also called the BRF (brown rice flour) method, its one of the OLDEST ways to grow mushrooms indoors. it has been modified and adjusted but it pretty much means a widemouth jar (any size) mixed with BRF, WATER and VERMICULITE, and with holes in the lid for innoculation
EDIT 2: instead of buying expensive organic brown rice and making flour, i just buy it buy the pound.
Organic Brown Rice Flour a $12 for 10lbs.. had this shit shipped to me... showed up looking like a bounch double bagged Kilos of coke haha
as for vermiculite... iv found it cheaper to buy at smaller flower shops.... walmarts in these areas only carry FINE vermiculite.. its better to use course, picked up a 4cu foot bag for $13, if i had to guess thats enough to do several hundred jars easy (make sure they dont store the bags outside)
also... i wouldnt buy the sterilized jars online... they rape you in shipping and all they did was the EASY part for you
