Inbred f4 generation selections from wild Cordyceps ascospores from Germany. These Ascospores have been domesticated through inbreeding for 4 generations and are well suited for hobbyists snd commercial farmers. 

Master syringe should be stored in the refrigerator upon receiving to maximize shelf life and fruiting capability (3-12 months under refrigeration). All LC is batch tested before shipping out. Shake well before using to ensure even distribution of mycelium in liquid. Master can be expanded to bulk LC utilizing 1-2 ml of liquid or whole syringe for optimum results. Expanded LC should be used in 2-7 days for best results, immediate refrigeration after 2-5 days of dark incubation can extend this window. 

can not be liable for handling temperatures during shipping during the summer. Clients in the southern US do best ordering in the fall, winter, and spring. I can no longer offer domestic courier shipping overnight. 

environmental parameters: 

LC expansion incubation: 62-72 degrees F (I prefer closer to 62)

Substrate Incubation: 70-72 degrees F

Fruiting: 62-68 degrees F, they can go as low as 50 with just slightly slower growth.

lighting: dark incubation until fully but lightly colonized for 2-5 days, place under lights for 12-24 hours daily for remainder of growing cycle starting at around 100-200 lux and increasing to 500-1500 lux after pinning. Maturation in 60-90 days. 

Bare bones LC for Master syringe expansion (mostly any LC recipe is suitable):

6 L water
3/8 cup dextrose
3/8 cup malt extract
1 TBS calcium carbonate

Sediment should be expected, simply agitate regularly when using. An LC recipe with calcium carbonate should not be used with a stir-bar as it will wear out the Teflon coating and grind away at the bottom of the jar.  I simply handshake once a day. 

Substrate recipe:

1000 ml water

5 heaping cups (1000-1200 g) brown rice

1 TBS (9 g) malt extract

1 TBS (9 g) dextrose

1 TBS (9 g) starch

3 TBS (19 g) nutritional yeast

2 tsp (4.6 g) pea or soy protein powder

1/2 tsp (2.4 g) calcium carbonate

optional additions: 

1/4 tsp (1.2 g) calcium sulfate 

1/2 tsp (4 g) kelp meal

The calcium sulfate can be replaced with more calcium carbonate if you are on a budget. You can also skip kelp.

This is the sub recipe I currently use with the instant pot tek from my YouTube video:

If you are prepping your substrate in jars use a ratio of 1:1.6 (grains:broth). A good amount for quart jars would be 35g rice to 56ml of broth sterilized for 60 minutes at 15psi.
