How much to inoculate

Inject 3-4ml of your favourite gourmet spore or liquid culture solution into injection port


The perfect incubation temperature for your kit (when using spores)

Gourmet spore syringes are never sterile, no matter what nonsense a vendor might tell to sell a product!

With this in mind, stay between 18-20C or 64-68F after injecting our kits with gourmet spores.

Getting this right will drastically reduce the chance of failure.

Though incubating at hotter temperatures will speed up mycelial growth more than it does at 20C, it will turbocharge the rate at which other nasties can grow!
And trust us, nasties will have found their way on to the mushroom caps prior to the spore printing process (and sneak their way into spore syringes).

Mycelium will actually outrun a lot of contaminants, just give it a fighting chance with the right temperature!


Incubation temperature when using a gourmet culture syringe

Feel free to up the incubation temperature to 26C after injecting our grow kits with gourmet culture syringes.

If there’s contamination in a gourmet culture syringe, it won’t matter which temperature you use – it’s ruined and the kit will become ruined too. There is no hiding from contaminants when it comes to LC syringes. And whilst on topic, never waste your time making an LC syringe from spores – it’s doomed to fail for everything mentioned above!

Extra advice

This grow kit is tailored for a medium-large flush size.

Squeeze the MycoBag at around 50-60% colonisation to help speed up the growth by spreading the mycelium further.. but, just do it the once or you may stall the growth!

Can take around 4 weeks to fully colonise in optimum conditions, but it depends on a lot of factors.

Again, this does not come supplied with a gourmet spore or culture syringe.

    The differences in all of the kits that we offer are simply the volume, container type and substrate.. if there's a certain gourmet mushroom species you'd like to grow, we would recommend researching which particular substrates they like to grow on and finding the suitable kit or raw substrate in our shop :)

    A Main differences: 1. Better, bigger yields than PF-Tek. 2. Better spawning potential for bulk substrates.
