Need some clarification on first bulk grow
    #9079292 - 10/14/08 11:39 PM (16 years, 3 months ago)

I have 20x 12oz pk tek jars that should be fully colonized in a week or so.

I plan on doing the 50/50 case tek with peat moss/coarse verm for the casing and coir for the spawn substrate. Should I add anything to the coir? Ive heard of people adding coffee grounds and various things but Id like to keep this somewhat simple unless the results of adding other things to the coir make a big difference.

Im thinking I would do a 1:5 ratio, so 240oz is 7.5 quarts, so 37.5 quarts of coir. Would it be better to just go with 1:4 ratio? Also, I have a 95 quart container, 1 foot wide, 2 1/2 feet long, 1 foot wide, should I just spawn and case all in this or do it in seperate containers? Only thing I can think would be better about different cases would be is if a case gets contaminated it wont affect all of my substrate. Is there a difference in yield if I were to spawn and case entirely in the container vs in other smaller cases? Also when spawning, if I can, should I leave as many cakes as possible in tact and crumble as few as possible to fill gaps between cakes then add spawn around that, or should I crumble all of it and mix the substrate and spawn together?

So after incubating the spawn until the entire spawn is covered in mycelium, case it with the 50/50 peat moss/verm mix. I hear 4% calcium carbonate and 15% crushed oyster shell with the casing mix of the peat moss/verm is a good addition to help regulate ph levels and give more flushes. Once done casing with about 3/4" of case mix, incubate and wait a few days for the mycelium to overtake the casing a bit and then should I patch or not patch? Should the patching material be pasteurized? When do I introduce light, when the casing material is covered in mycelium? Then I begin fruiting it by lowering the temp to 75 and keeping the humidity in the FC at 90%.

Does theat process sound good? Any help and clarification would help. Ive been reading a lot about all this lately but just want to make sure what I think is right in my head is right in the heads of people who know what theyre talking about.

wow alot of questions: you can use straight coir, but the coffee grinds help alot. mixing some verm with the bullk coir will fluff it up a bit and it will colonize faster. breaking up the cakes and mixing evenly in the substrate is the way to go. more inoculation points in your bulk. so it colonizes evenly. incubate till fully colonized. this means keep it covered and dont peek alot cuz you let out built up c02.doing so you give it fresh air. which can stall a spawn run because fresh air exchange is a pinning triigger. when you case you do want thecasing pasturized and any patching pasturized. u can either case and fruit right away or case and wait till you see a little myc poking threw  and patch those spots then fruit.. patching promotes a more even pin set .frequent air exchange, high humidity and bright light are pinning triggers hope i hit most of those questions:)

you want to hit it with the fruiting triggers all at once. so after its cased and patched if you do so- then put it in a fruiting chamber that  has frequent air exchange,high humidity and bright light all at once! those 23 watt daylight compact flourscent bulbs work fine for the light twelve hours on and twelve off.

noobieshroomioes coir bucket tek. will give you an idea how he used coir. Straight

Use a ration of no more than 1:3. The less spawn you use the longer it will take to colinise and the higher chances for contamination.

You can start out lower if you want, 1:2 or even 1:1.

I would go with several smaller containers rather than 1 big container. Just incase of contamination.

Look up the 50/50+ casing tek

Once your spawn and bulk sub are mixed, cover with foil and poke a few holes in the foil to allow gas exchange during colinisation.

Once fully colinised, you can put straight into fruiting condtions. Some people wait until myc has poked through and then patch and into fruiting some just straight into fruiting. Its just personal preference.

Go with a 1/2" casing layer, light has to be able to penetrate the casing layer and reach the surface of mycelium.

Thanks for all the help everyone and sorry for so many questions. I just wanted to make sure what I thought was the right procedure really was and I see there are some things I need to improve upon.

I was looking at large_dose's coir tek; so I think I'm gonna go with:

4.5 quarts water
1 brick coir
1 quart coffee
1 quart verm

For the spawn mix.

Would anyone have a suggestion on how much calcium carbonate and crushed oyster shell to the 50/50 casing mix I should add?

Yeah, I figured doing smaller containers would be the best idea. I'm not too worried about contamination as I inoculated all 20 jars with no problem, yet better safe than sorry.

Thanks again for the help.
