30-40 half pints
    #539433 - 02/03/02 04:07 PM (21 years, 9 months ago)

i have grown before, typically using pf style jars and casing, but i am familiar with rye and a few other grains as well. i am planning on starting a project using about 30-40 half pint jars. i am planning on using p.c. b+ syringes (4). i'm just not certain about a few things and i want to make sure i'm making the right choices here. i plan on doing a casing of some sort (not just plopping the cakes individually on perlite or something). i plan on using a cooler for the terrarium with a plexiglass window on top (silicone glued on). i have used plastic storage bins before, but i found that they leaked and didn't keep the terrarium humid enough.

i guess the questions i have are:

what kind of substrate should i use? pf? rye? millet? a combination? i don't have a pressure cooker- and i didn't really want to buy one. my plan is to use the pf formula since you don't need a pressure cooker, i have been sucessful with it before, etc. BUT if another formula would work much better here- please give your input.

once the 30-40 half pints are colonized, what would be the best way to case them. more specifically- how thick should i make the substrate layer? the cooler that i will be using will most likely be the 36-48 quart size. should i crumble ALL the cakes and dump them in one cooler? should i slice them? leave them whole? should i use more than one cooler for this much substrate?

thanks in advance for any replies.

I dunno d00d...

I would rather buy a pressure cooker (you can get one for $50 brand new @ walmart that can handle quart jars) than mess with 30-40 half pint cakes.

The yield from such a high amount of cakes will be ok.  But you are going to be spending LOTS of time messing with them.

You'd be better off doing 12 quart jars of rye/millet, but you need a PC for that.

In general, if you want to grow bulk, you should use grains in large jars. 

From one and a half quart jars (cased), I got apx 40 grams dry.  One 1/2 pint cake can yield anywhere from 2-5 grams dry (5 if you're lucky) over it's whole lifetime (multiple flushes).

The cakes take a long time, plus you will need a few terraniums for all of them.  ALso, casing 1/2 pint cakes is not as good as casing grains in my opinion.

Just my opinion :smile:

30 - 40 half pints is just plain retarted. if you want to be making large amounts of casing, definately invest in quart jars, or 1 pint jars at least.

i think with you should maybe go back to your rubbermaid terranium setup, if you dont live with your parents, use this: 100 watt fish tank heater, 25 gallon fish tank pump with an airstone, and the biggest fucking pickle jar you can find to stick all that in there. my humidity level is around 90-95 percent, it works well so far

You don't have a pressure cooker.....hummmm
Better stick with Brown Rice Flour or Rye Flour.....then.

Your gonna need a bigger terrarium....go buy some big Rubbermaid clear containers......they are cheap.....some are on sale now for like 50 % off.

30 to 40 jars is alot.....lolz
I have used up to 60 jars.....and i have 2 incubator's......and 7 terrarium's.

I wouldn't case all the jars together into one container if i was you.
There would be a higher risk of losing them all.....if you get contams.
Maybe you should make smaller casings and read some of the casing Teks.

And i thought 14 half-pints and 6 pint jars was extravagent!!
Half pints are good though for quick colonisation - without a PC you should stear away from rye and millet - id suggest a cheap brf and manure (bulk) substrate

thanks for all your input guys.  i suppose if i only bought 10 quart jars (instead of 40 half pints) i could use the extra money to get a pressure cooker.  but i am concerned about using whole grain.  i have used rye before and if colonized wonderfully, but it didn't flush as well as the pf cake casings i have done.  cased using 50/50 jiffy mix.  it also seemed (and i believe i have read before) that whole grains like millet and rye especially contaminate much easier.  is that true?  it also seems like there is a lot of guess work in terms of whole grain formulas- getting the water content right mostly.  the way that i did whole grain rye before is:  i soaked the rye in distilled water in the quart jars overnight (punctured lids on)- i poured the water off- then pressure cooked for 1 hour.  (i don't have the ressure cooker anymore, obviously :smile:.  it seemed to work well.

how does this sound:

using quart jars, 200g of organic millet, 200g distilled water, knife tip of gypsum (how much is a knife tip?).  let this soak in jars with lids on for 24 hours- then pressure cook for 1 hour.  i would use polyfill through a single hole in the lid.  an extra hole will be made for inocculation- jars will be covered with tinfoil when pressure cooked- inocculation holes will be taped after inocculation. 

this is basically from the faq- anything else i should do?  how many cc's should each quart be inocculated with? 

once jars are fully colonized- what is the best way to case colonized millet?  i still think i am going to use a cooler- i always have problems with stuff drying out.  how thick should the substrate layer be?  i ask because i'd rather have a couple heavily fruiting terrariums than a bunch that are so, so.  it seems to me that the more colonized substrate you have working together in the same casing, the better and bigger the flush. 

thanks in advance.
