Zamnesia Grow Kit

McKennai Growkit  

Learn how to grow your own batch of magic mushrooms using the Zamnesia Grow Kits.

The Zamnesia Magic Mushroom Grow Kits are straightforward and easy to use. They contain everything your mushrooms will need to thrive, all you need is some water and patience. The result high yield of some psilocybin goodness! Each tub contains a layer of perlite for water retention, a layer of mycelium for mushroom growth, and a thin layer of vermiculite to create a casing layer that both protects the mycelium and provides a microenvironment ideal for growth.

Important note: Always thoroughly wash your hands before handling the kit or working with them in any way. Mushrooms are very vulnerable to contamination; it is important to keep your hands sterile. Under no circumstances breath into the bag. It highly increases the risk of contamination.

Product contents: With each Zamnesia Grow Kit you will receive: 1 Grow Kit – filled with everything your mushrooms need to grow, 1 Grow Bag, 2 paper clips. You will additionally need: clean water, a spray bottle, a warm bright place out of direct sunlight, patience.

We highly recommend NOT to use any aluminium foil to grow your mushrooms. This isn't necessary at all.



The first step is to give the mycelium the water it needs. To do this, carefully take off the lid and gently fill the tub with cold water. The mycelium needs to be fully submerged.



Replace the lid and allow the grow kit to sit for 12 hours – allowing the water to soak in.

Important: Do not allow the kit to sit for longer than 12 hours while full of water.



After 12 hours, lift up the corner of the lid and gently pour out all of the excess water. The kit is now ready to begin growing.



Take off the lid and place it to one side (you will need it later). Place the Zamnesia grow kit in the supplied grow bag. Ensure that the bag is standing upright with the opening at the top – you will need daily access to it.



Close the bag by folding the top twice and secure it with the supplied paperclips.



Place the bag with the kit in it in a well-lit area that maintains a temperature of 20-25°C. 23°C is optimal. Do not put the kit in direct sunlight! Mushrooms require warm temperatures and indirect sunlight to thrive.



Set it and forget it!


Magic Mushroom can take anywhere between 1 to 3 weeks to start popping up their heads. Patience is key here; do not continually open the bag to have a look – you let warmth and moisture out while potentially letting contaminants in. Only open the bag once a day to give it a quick misting. Eventually, the mushroom heads will begin to appear. When this happens, your mushrooms will develop rapidly, and usually be ready for your first harvest after an additional week of growing. The great majority of these mushrooms will reach maturity at the same time, allowing for one large harvest.


The best time to harvest your magic mushroom from the Zamnesia Grow Kit is just before the veil under the caps start to tear. The best way to time this is to watch your mushrooms carefully as they grow. When the veils of one or two mushrooms have torn, you can be pretty certain the rest are not far behind, meaning this is the ideal time to harvest. To harvest, gently grab a mushroom at its base between two fingers, and twist with a soft upwards motion. They will come loose. Do this for all of the mature mushrooms.

There is more where that came from:

You have now successfully harvested your first flush of mushrooms, but the mycelium in the kit has more to give. You can repeat this entire process, beginning at step 1, to gain another harvest, and even a potential third, fourth and fifth. However, before you begin the process again, make sure to remove any remaining shroomlets from the kit that didn’t make it to maturity. You need a clear cake, just like when you first received it.

Storing your zamnesia grow kit:

We strongly advise against storing your kit. They should be used as soon as you receive them; storing increases the risk of contamination. If, for whatever reason, you must store your kit, place it in an airtight bag and then put it in the fridge at 4 to 8°C. It should be ok here for 3 to 4 weeks. Once again, we do not recommend doing this, only do it if you have no other choice.
