Magic mushroom grow kit: No spores needed

There is no need to inject spores in a magic mushroom grow kit after the first harvest, not even after the last harvest you manage to get out of the grow box. The reson is simple:  The substrate of the magic mushroom grow kit is already fully colonized by the mycelium.

The mycelium in one grow kit has the potential to fruit mushrooms up to 4 flushes. So, no need to inject spores into the grow kit after harvest. 

Substrate kit: Spores are needed

On the other hand, if you have a substrate kit, such as the Mondo Fast Fungi or Kilo kit , you will need spores from a spore vial  or a spore syringe.

These kits consist of substrate only and spores have to be injected if you want mushrooms to grow. 

The mushroom substrate kilo kit is a pre made substrate bag with a spore injection port. This mushroom grow kit contains sterilized substrate made of  vermiculite/brown rice flour , also called PF Tek or BRF. The mushroom substrate bag comes with a 25ml vial of liquid culture, a medium were you can germinate your mushrooms spores in before inoculation. The mushroom substrate bag is easy to use. You only have to inject the mushroom spore strain of choice into the substrate to start growing your mushrooms. The substrate is big enough to produce a great yield

After one harvest the substrate will continue to fruit more flushes of mushrooms until the mycelium and substrate have been extinguished.

In any case, most of this information regarding our kits is also on the instruction documents for the different grow kits.
