A Good Reliable Bulk Sub Recipe

Quintin's "Too fresh to flop" bulk sub preparation tek

This Bulk sub recipe for a 50l tub and 10l substrate and 3l grain spawn:

🔅   650g coir
🔅   4,5l water
🔅   2l verm
🔅   4 tbsp gypsum

If u want to add h.poo, for every liter of poo replace 65g coir.

For smaller tub volumes, roughly divide the above quantities to match your tub volume.

Steps:
1️⃣   Get the water boiling.
2️⃣   Mix the gypsum into the water.
3️⃣   Add the chopped up coir pieces first and stir till there are no dry bits left.
4️⃣   Add the verm and h.poo (optional) and stir evenly.
5️⃣   Leave the pot with a lid on its lowest temperature setting for 30mins to steam pasteurize.
6️⃣   Let it cool till room temperature which is around 3 hours for me.
