Agar says:
"You want the NITROGEN level under 3.7%

H/poo is about that.

Adding more may/could/would cause damage, rather than benefit.
To hot & it burns things."

How much blood meal would you suggest using Agar?
"Not much.
Maybe a tablespoon to 5 lbs of dry h/poo.
Which would be just under 15 lbs of wet substrate."

"For nitrogen, you can add blood meal to all substrate materials including horse manure, at the rate of one tablespoon to ten cups of substrate. It really does make a difference in the quality of your crop after harvest."

Having said that... Here's a way to spawn to Straight COIR, and nothing else.

First, you need to hydrate the COIR and I recommend adding 160F water. 1gal per brick of Bed-a-Beast brand COIR. Let this sit in a covered bucket for about an hour or till cooled.



Line the tubs with tinfoil. This helps to keep light out, and to also keep side pinning down to a minimum. Once the substrate starts to shrink, it will stick to the foil and will shrink with it. (I recommend using the large foil, as it's easier to manage)



Once that is complete, take handfuls out and place in 12Qt. Sweater boxes. (get these from walmart). Each brick of coir will fill 2 Sweater box tubs with about 3 to 4 in. Each. After that, Dump 1qt jar of spawn (or equal to 1 qt) into the sweater box.



Mix together thoroughly, once complete i recommend using a little bit more spawn to place on top. This helps to aid in a contam barrier by colonizing the top first. Cover the Trays with aluminum foil, and poke holes into it (pencil size). Cover those holes you just made with Mico-Pore tape (also known as Gentle Paper Tape). Incubate the casing around 80F Wait about 10 days or until completely colonized.



Once it has been fully colonized.. we'll need to case it. I recommend using the  50/50 + Casing Tek. Case the tray... then place it back in incubation Covered for another 3 days.



Uncover the casing made, and patch any little white patches of Mycelium growing through the casing layer. Patch lightly, this will help on growing an even pin set. Once you have covered the exposed Mycelium, you can place the casing tray into your Fruiting Chamber



Give 12hrs. on and 12hrs. off light cycle... Almost any kind of light will do. Keep the humidity in any type of Fruiting Chamber to around 90Rh. Give fresh air at least 2x a day. (hand fan, cool mist humidifier, air pump)

In about 7-13 days pins will form.



Which then flourish in about 3-5 days after that.



Enjoy
