Sterilised Substrate Kit

(65)

This sterilised substrate box is the perfect habitat to grow magic mushrooms at home. First, you need to inoculate it with the spores of your choice. Then, you must keep it warm as the mycelium colonises. Finally, you can open it up and let the mushrooms grow, and before you know it, they’ll be ready to harvest!

Sterilised Substrate Kit: Perfect for Growing Magic Mushrooms at Home

This sterilised substrate contains a mixture of whole oat, vermiculite, perlite, and gypsum, and has a moisture content of 60–65%. This makes it the perfect environment for Psilocybe cubensis mushrooms. To use it, you’ll need either a spore syringe or, even better, a liquid culture containing the mycelium of your choice. Both will work, but a liquid culture is faster and has a greater chance of success!

This kit contains:

  • One box containing a sterilised substrate
  • One humidity tent/fruiting chamber
  • A paperclip (for the humidity tent)
  • Alcohol swap
  • Injection port

Using our kits to grow magic mushrooms is simple. Here's how it's done:

1. Inoculate your substrate using a liquid culture, spore syringe, or vial.

1.a. If you're using a spore vial and a 1200ml kit, inject the substrate with at least ½ of the contents of the vial. If you're using a 2100ml kit, use a full vial for fast and effective inoculation.

1.b. If you're using one of the many spore syringes available from our Shroomshop, use 5ml to inoculate a 1200ml substrate kit and 10ml to inoculate a 2100ml kit.

1.c. If you're using a ready-made liquid culture by Acid Shroomz, use between 2–5ml of culture for every litre of substrate.

1.d. If you're making your own liquid culture using a Mondo Liquid Culture Vial, inject 2ml of spores into the vial and wait at least 2 weeks for the spores to grow into a liquid culture (i.e. active mycelium). Then, inject the entire vial into your substrate (regardless of whether you're using a 1200ml or 2100ml kit).

2. Cover the substrate with a lid and keep it in a warm, dark spot. Mycelium does not need light to grow. For the best results, keep the ambient temperature around your kit consistently at 23°C. You can achieve this by placing a heat mat under your substrate kit or by storing it in a small cupboard or tent with a heater. Remember to use a thermometer to monitor the temperature in your grow space.

3. Leave the box undisturbed while the mycelium colonises. This can take several weeks, depending on whether you used a spore solution or liquid culture, as well as the stability of the temperature in your grow area. You'll know your growing medium has been fully colonised once it's completely covered in a white, wool-like substance.

4. Once the box is fully colonised, it's time to fruit your kit. To do so, open the box and fill it with cold water. Put the lid back on, and leave it in the fridge for 24 hours.

5. Drain the water, and place your box in a humid grow tent. Regularly mist the walls with water, and keep the ambient temperature at 23–28°C for best results. Provide your mushrooms with some natural light to help orient them and ensure they grow in the right direction.

6. Open your tent twice daily to allow for some air exchange and mist the walls to keep the humidity high. Allow your mushrooms to grow, and harvest them once they are mature (before the veil on the underside of their cap tears to release spores).

7. Following a harvest, repeat steps 5 and 6 until your substrate stops producing mushrooms. Note that the second and third flushes are usually the biggest.

    This is unfortunate
    After buying several products from zamnesia. Unfortunately the 2100ml substrate has let me down. Have purchased over 10 and out of those 10 2100ml substrate. I only have 3 that have started to colignise . Although I've had replacement for the ones that are unsealed yet had mould formed , and zamnesia where quick to replace but upon arrival of replacement 1 of 3 already had mould. Upon me inoculating them ( in highly steriliezed environment ) 7 of 10 have got mould . I still have 3 that are slowly colignising which in my opinion including replacements it's not good . Time and culture wasted . Which is total of over £160 so not impressed. So after all is said I will not buy this product again and I will stick to making my own substrate , but will continue to buy cultures and spores from here to carry on my cross strains development and seeing the growth studies. If I could give 5 stars for customer service. And a separate rating for substrate aka 1 I would. But unfortunately not option to rate site, customer service and products separately

    SCHWINDENDE QUALITÄT!!!
    Habe insgesammt 4 solcher Kits bestellt und bis jetzt sind 3 mit Grünem Schimmel kontaminiert, nicht mal 2 Wochen nach der infizierung. Ich habe extra sehr steriel gearbeitet und auf Sauberkeit geachtet, deswegen liegt das Problem definitiv bei Zamnesia, auch weil es bei fast jeder Bestellung aus dem Shroomshop Probleme gibt. Hatte jetzt auch bei 2 Zuchtsets Grünen Schimmel, im letzten Jahr hatte ich nicht einmal Probleme damit. Wenn Ihr so weiter macht, verliert Ihr mich als Kunden. Kriegt die Qualitätssicherung auf die Kette, sonst wird das nichts.

    Far too dry
    Recived 2 of these kits both of them were extremely dry to the point it's unlikely any mycelium would even spread fed up ordering now almost everything has either come contaminated or there's been a problem

    Too dry, bad customer service when contacting Zamnesia
    I purchased this substrate kit, immediately noticed it looked too dry before innoculating. I used a liquid culture also bought from Zamnesia. Followed all the sanitisation procedures and used only .75ml of liquid culture for the box. There has been no colonisation and it has been kept at ideal temperatures for almost 20 days. I know the liquid culture I purchased is okay as I have used it on several other spawn bags with no issue. After sending an email to Zamnesia support team, they sent me a response clearly not having read my email properly the first time, thinking I was complaining about the liquid culture. I sent another email, but all I had in response was that they closed the inquiry. I have also ordered two Zamnesia own brand grow kits which turned up not fully colonised. One box was only 70% and the rest still uncolonised substrate. I emailed about this also, and again got a response which was vlear that hadn't read my complaint properly so again I had to clarify, and I have not heard anything back. I'm assuming they will probably close this inquiry also, after I feel I've wasted almost £80 in total with them. It seems the Zamnesia own branded kits are pretty bad, since all 3 I've had have failed, or not been prepared properly before they took my money and sent the unfinished product to me. The copelania hawaiian kit I ordered was incredible and worked within days; don't buy the Zamnesia generics.
