Advices needed for commercial grow
    #23582868 - 08/27/16 09:26 AM (7 years, 5 months ago)

So the story is i'll soon move into a new house with insane space available.
For a long time i want to grow edibles (i grow some edibles for me actually at a small scale)

i'll have enough space to have a dedicated lab, and fruiting room.
Lab(30m²)
Old stables (50m²)
storage space (150m²)
and another building which side the house , a shed with 2 open walls which is 200m².

Considering all the post done here about it, i know i should not start big.

How many bags should i try to do each week to have a sustainable production
(let's say for 1 minute i'll do oysters)

How much can i expect to loose to contamination is everything is done right?

Any thread in here that would explain the usual quircks when growing edibles and slowly scaling up the production?


Thanks for you time :wink:

What is your current equipment and experience level?

Do you plan on starting with straw logs? If so then your contamination rate should be low as long as you catch any contams in the spawn. If you can find a cheap reliable spawn producer it would get you off the ground a lot quicker and with no lab cost on startup, you can always add the spawn production and lab in after. I highly recommend using hot water bath pasteurization for starters. A bale of straw a week should put you around 30-50 lbs of mushrooms per week. I found mixing fuel pellets in about 20-30% really helps with maximizing pasteurizer space and making the logs more nutritionally dense with no added risk of contamination. 

The other route would be your pick of sterilized sawdust/soybean hulls/rice hulls/wheat bran. Get yourself a AA941 and do batches of 9 bags until you get everything down then build a 55 gal drum sterilizer or larger for 40+ bag batches. Expect 1 lb per 5 lb bag low side, closer to 2 lbs once you dial everything in.

Well i'm ok with cubensis, pans and stones,
also done some oyster, shiitake and reishi (in tiny amounts)

I guess my spawn is not perfect, but i rarely got contams now.

In france it's not even debatable, taxes are so high, if you can do something yourself, you do it yourself, otherwise prices tend to explode.
(and i have enough money to build a good lfh and buy basic lab equipments(+ what i already have))
(and yes Socialism is a cancer)

For substrate i found big bales of straw, 200€ per ton
and some compressed hardwood (mostly oak) 400€ per ton

Yes i was planning to get one of the big AA to replace my presto(sad thing is the shipping price is horribly expensive, but that's probably my only option anyway, regulation prevent selling non professional sterilizer to individuals here)

I had big trouble sourcing some big drum over here, maybe i didn't look at the right place...

The biggest mushroom spawn factory in the world is in verome France.  I'd suggest giving them a call.  It's either sylvan, amycel, or somycel.  Can't remember.

Should i plan something regarding light / air exchange / temperature in the closed building?

Maybe some guidelines like  X watt per m², i can imagine the number is pretty low, but maybe the light currently installed won't be enough (i was planning to use the stable first which has 4 100w neon bulb)

And i guess some way to bring fresh air in, if needed (if the amount of fresh air with door open is insufficient)

chk..

Your going to need to exchange your air at least four times an hour to removing co2 buildup in the grow room.

Check out GrOwer You-tube channel.

Thank you so much :inlove3:

I'm more of a visual learner and I am very grateful there is a step by step process of how to run a small scale mushroom farm. I've been wanting to get into edibles for a very long time

I was said it's running.

But i would really like to know the specs before buying that, ofc
And since the seller very probably never used one, i can't get more info from him

That appears to be be a dry sterilizer? If it doesn't use moisture then of no use.

Just read the manual. It refers to it as an oven with natural ventilation.It is also listed as 3 phase. I think you are looking for an autoclave. Something that can be pressurized with steam.
