Stepping up to bulk
    #2907478 - 07/20/04 04:19 AM (12 years, 4 months ago)

A friend has some PF style BRF jars incubating that are about ready to fruit, he originally planned on doing cakes but is now considering going bulk and spawning to straw via crumbled cakes, then casing in a rubbermaid. This is my friend's first grow attempt but has had no problems thus far. Would Verm\Coir be an efficient casing layer? Would anyone advise against trying this on a first grow? Any tips would be appreciated.

Hell yeah it would. I highly reccomend this, as its almost fullproof - this was the style of casing I stuck to, with great results. I always used a kittly litter pan/box with 3 pints of substrate and a layer of sterile 60/40 verm/coir on top. Glad to see you say you have an incubator setup, this is key in getting that casing to colonize quickly without an attack from contaminants. Make sure to keep the casing covered with foil or something of the like when it's in the incubator, patch it up and fruit. With this type of setup, I would get 1-3 ounces per casing (using perlite as humidification during fruiting.) This was with the PES Hawaiian strain, which gave me great results. Oh... if only it was still those times, with 70+ jars incubating at a time... *sigh*. Go for it, you'll appreciate the yields off of casings much more, and you'll never be fruiting cakes again.

Good luck!

Yes its a good casing layer.

But IMO there is no need to case bulk.

for bulk subs I really recomend using millet based grain a quart colonizes than a half pint PF cake faster and breaks up better than BRF too
keep in mind that you have way way more chances of loosing your grow to contams by going to bulk
as for a incubator with straw I would say dont do it it heats up on its own
I did a little experiment with a bulk and put a thermometer in the middle of the tub it heated to 87 for three days and the temp in the room was 75 that was pretty freaky to see such a difference

My friend is using a 95qt rubbermaid as a terrarium, would it be best to make individual casing trays(straw) and use perlite to humidify, or would making the entire container a casing produce higher yields? If so would it still require an extra source of humidification?

If you are going bulk you don't need any PERLITE,Casings provide their own humidity if contained(in a fruiting chamber)and adding any perlite is overkill.Bulk casings need about 80-85% relative humidity and no more,they provide the rest.Along with an occasional misting,thats all that is needed.

Would you say that 50/50 Verm/Coir would be an effective casing layer? Also, would there be a difference between placing the mixture directly in the plastic rubbermaid or using a larger tray inside the rubbermaid? Is fanning 2-3 times a day efficient this way, and how often do you mist? Thanks for the help.

Just use straight coir. I dont see why wnayoen would use verm when coir alone works great. Just dump it all in the rubbermaid and mist once a day at the most, only mist the walls.

Ok, let me make sure I've got this all right then:

First, pastuerize the straw. Once the straw has cooled, crumble the fully colonized PF cakes. Alternating layers, place straw in the terrarium, layering crumbled cakes on top, until the depth is 4 inches when compressed, the top layer should be straw. Cover & tuck with perforated plastic and let colonize at room temp for 10-14 days. Remove plastic, add 2 inch only coir(what would be the advantage to using some part verm?) casing. Recover with plastic, leave untucked and let colonize. Upon colonization, remove plastic, place lid on terrarium, fan 2-3 times a day, mist walls once every other day(h2o2?).

Let me know if i've got it all covered, If all goes well I'll keep you updated on my friend's progress. :stoned:

2 inches coir might be much. someone correct me on this, but i think u want the casing layer 1/4 of substrate, which in ur case would be 1 "

1 inch is thick too with my bulks I go real thin just cover it enough so you dont see any white
a casing is not even really needed just very benificial

Ok, because i've had trouble locating coco coir at any local pet shops. If anything would straight verm still do the trick, or if no coir, no casing? While we're discussing whats not really needed, what about light cycles, and how important is compressing the colonizing straw? This part does seem important... Although i do find the bulk neglect report interesting...

My friends mom uses straight verm and it works great, haven't tried the coir yet to compare to though...

you can order coir online in a brick that easily expands to 8-9 times its size with water, and it holds a lot too. if you're comfortable paying for the shipping.

3$US for a brick of it, plus a few dollars for shipping:

Use coir less tehn 1/2" thick and you have to patch once teh growth pops through. Steralize some extra coir and uce a clean spoon to cover the overlay. Start to fruit the next day or two and you should get a even pinset. Any light cycle works, For my friends bulk i put a 13w cfl at the top and hooked it up for 30 min on 2 times a day and it works fine. Leave the light off for colonization you only want light for pining after you case and patch.

I find straight straw contams easier then straw manure, i like to mix in 10-20% composted manure to kep back contams and introduce more benificial organisims that make pasturization work.

4" deep is alright but you can go as deep as 6" so go for 6" an get more larger flushes.

Don't even bother using coir then. It dries out way too damn easy IMO. I'd say go 50/50 vermiculite, peat moss. The coir just retains the moister, while the peat moss retains the moister, but at the same time adds beneficial nutrients for the mushrooms.

Well since I've had no luck on the coir, and the jars will be ready in another day or two. It looks like it will have to be 50/50 Verm/Peat then... do you also add lime to regulate Ph?

so it's gonna be straw, inoculated with crumbled PF cakes, and layered to 6' with a 1.5 inch casing layer composed of verm/peat.
It'll be 7.5 inches in a 14 inch tall plastic terrarium, with no external source of humidification, daily misting of sides, and fanning twice a day.  :stoned:  I think...  :smirk:

1.5" thick caisng is way too thick, 1/2 is still too thick for my likings, i would never near 1". The thicker it is the longer it takes to patch and the growth has more time to get uneven. Since its such a low volume container you will have to fan 3-4 times day, use a full sized rubbermaid to keep it simple and so you have room for big fruits.
