Jack Frost Kit Champignon Magique - Philosophr®

Jack Frost Magic Mushrooms, une variété de champignons psilocybe cubensis connue pour sa puissance élevée et son apparence distinctive.

Le champignon Jack Frost est un croisement de True Albino Teacher et d'Albino Penis Envy, deux variétés réputées pour leur beauté et leur puissance.

Jack Frost porte bien son nom en raison de son apparence glacée, des champignons d'un blanc pur avec des chapeaux plats qui se recourbent vers le haut lorsqu'ils arrivent à maturité.

Attention : il s'agit sans aucun doute du psilocybe cubensis le plus puissant de notre catalogue. Adaptez votre dose en conséquence.

Description du produit

Jack Frost mushrooms kit from Philosophr® the new standard of premium mushrooms!

The Jack Frost 2000cc premium magic mushroom kit is a different way of growing than you might be used to.

It is grown directly in a grow bag without the need for a grow box which, in turn, is a lot stronger against contamination.

Since the bag will only be opened once before you can enjoy harvesting the first big flush. The Jack Frost is specifically bread to grow extremely potent and massive mushrooms. Welcome to the new era of home cultivation.

  • Larger yields, more mushrooms

  • Easier to handle, very contaminationproof

  • Easier instructions, less worries about your mushrooms.


  • 1x Grow bag - This contains substrate with active mycelium (the cake) The bag has micron filters to keep contaminants out and let fresh air in.

  • 1x Large Bag clip  - Easy to use and a more secure way of closing your grow bag.

  • 1x Rubber band - To place around the substrate at the top to prevent side growth.

How to store the Jack Frost grow kit correctly

It is recommended that you start the cultivation process right away when you receive the grow box. If you decide to start growing later, which may affect the quality of the box, you should store the grow kit for a maximum of 2 weeks in the refrigerator (2°C to 8°C). You can leave the growbag with mycelium in the box and place it in the fridge. Make sure your fridge is clean and free of mould. You can place it inside a clean plastic bag or a soaking bag as an extra precaution.

Jack Frost grow kit instructions

What do you need?

  • Clean environment—Work clean to prevent other fungi and bacteria (microorganisms) from contaminating your growkit.

  • Potable water –  Always use clean tap or mineral water for misting and soaking. Never use distilled or demi water.

Recommended products to use in addition

Room Preparation

  • Close all doors and windows and let the air settle in the room so no drafts can blow unwanted contaminants into your grow bag.

  • When taking the grow bag out of the box, place it only on freshly disinfected surfaces .

  • Make sure you work with clean hands and arms. We suggest using surgical gloves  and/or a good disinfectant to clean your hands and arms when handling the kit. Use a facemask  to avoid breathing into the grow bag and on the cake.

Starting The Process

  1. Take out the bag from the box and unroll the bag.

  2. Open the bag and let fresh air flow inside by pulling the sides away from each other; immediately close the bag with the clip again.

  3. Place the rubber band around the bag at the same level as the top of the substrate to reduce side pinning.

  4. Place the kit in a clean and comfortable environment for the mushrooms. The temperature is ideally 23 degrees, do not put them in the dark, and never in direct sunlight.

  5. Now all you need is patience. Jack Frost takes about 2 to 4 weeks until it is ready for harvest. No airing is needed.



The ideal temperature is 23°C. Make sure the temperature stays above 21°C and does not surpass 27°C. To prevent temperatures from dropping below 21°C, you can use a thermal heatingmat. Especially in colder regions or during winter, a thermal mat becomes essential for maintaining the ideal temperature. Always insert "spacers" such as pencils between the bag and the heat mat so that the temperature can dissipate and is not concentrated straight on the substrate. 


Jack Frost only needs indirect sunlight to understand that there is a day and night cycle. Light is important for a good yield but also make sure that there is never any direct sunlight shining on the growkit.

Water / Misting

The Jack Frost growkit has enough water inside the cake to last you at least 2 flushes. So no additional water or care is needed. Just set it up and wait.


Jack Frost has a slower growth rate than other cubensis strains but grows incredible amounts. Some patience is required as the first mushrooms typically show up somewhere between 2 to 3 weeks. Once the pins emerge, the mushrooms are ready for harvest approximately one week later.


Jack Frost, like all cubensis mushrooms, is to be harvested as soon as the veils around the caps start to break. After the veil breaks Jack will still grow a lot in size but this will mainly be water weight. If you pick them when they are completely open they will be harder to remove and this may break the cake. Also if you harvest them later the mushrooms will be hollow inside after drying. Picking them at the optimal time preserves their potency.
The best way is to harvest mature mushrooms while allowing others to continue maturing. In practice, a lot of them will be ready roughly at the same time.
To harvest the mushrooms simply roll down the bag to the substrate so you can easily pick the mushrooms that are ready.
After you have harvested all of the mushrooms you can just close the bag again, place the kit back on the growspot, and wait for the next round of pins to come out.


Jack Frost only needs to be soaked after the second flush, until then there is enough water inside of the kit for them to grow. One exception to this rule is when pieces of the substrate crumble off when you are harvesting your mushrooms. If that happens it is also time to soak the kit.

To soak the kit; take clean tap water or spring water fill up the bag until the substrate is submerged and leave it overnight, the next day you can drain the water out and let the kit grow again. After soaking there might be some discolorations on the substrate but if the kit still smells good it is good to go.

The end

When no more mushrooms have grown after 4 weeks that means that the cake is exhausted and it is the end of the kit. Also if you see a green discoloration in the kit it is contaminated and it should be thrown out. There can be other discolorations that are no problem so do send a picture to our customer service if you are unsure of the looks.

Efficiency Commentaire par Predictor
Effortless growing. Everything went as written in the description. Mushrooms are huge and grow fast. I can feel the cake shrink and become lighter in just a few days. They are also potent. Try starting with half of what you usually need with Golden Teacher. Hard to eat plain raw but they go well raw with soy sauce. (Posté le 21/05/2024)
Just what you've been waiting for Commentaire par Roman
Hello everyone. I have tried many different grow kits from this website, and have been very satisfied with the products, however, Jack Frost is my new favorite. The other growkits were pretty easy to grow - activate and then once the first pins occur, just open the bag twice per day, air out and mist some water in the bag. Jack Frost brings the simplicity to the whole new level: all you have to do is open the bag once you receive it and close back again - you don't have to do anything more - just wait for the mushrooms to grow and harvest them. Just like the instructions said, the bag had enough moisture inside for 2 yields, so you will be able to harvest a couple of hundred grams without having to do a single spray. Regarding the potency, Jack Frost is as potent as other cubensis strains. Therefore, Jack Frost requires by far the least amount of effort per unit of psilocybin produced, compared to anything else I have seen. To sum up, if you wanted to grow your own mushrooms, but was not sure if you can committ to airing them and watering twice per day (if you travel a lot etc.), Jack Frost is what you have been waiting for! I am glad that growing your own medicine is becoming more and more accessible to everyone. That's my take on Jack Frost - hope this review was useful. All the best and take care!

Biggest Shrooms I ever harvested Commentaire par Maximilian
These shroomies are defenitly worth trying. defenitely the biggest and most potent on the page. My first yield was just one shroom but it filled out the whole inside and weight 101g :D. A week later the rest came and were a bit smaller but still hudge. I tryed it a couple of times raw and had a good time. quite strong body high (a bit like on xtc) compared to the other cubensis strains. 2nd flush is already sprouting... Will buy again.
Cheers! (Posté le 13/05/2024)

Love those! Commentaire par Flo
They are easy to set up, the yield on my first flush was nearly 300 wet, tryed some fresh and its enough to let me talk with god for a long time! (Posté le 27/04/2024)
Easiest kit ever! Commentaire par KD
Since I need to travel more for work these days, I asked the fabulous customer support team if there was any kit that would still grow okay without daily attention. They recommended Jack Frost, which was even simpler than I expected – I did the usual careful sanitary set-up on the day it arrived, in a space in my flat where it would get the right kind of light, then – following the instructions – I didn't even touch the kit again until the first flush was ready to harvest 2-3 weeks later. Huge flush, very pleased ... just one note of concern – I probably harvested a day late, and some of the mushrooms were already starting to degrade a little bit. I'm wondering if the Jack Frost growing method might yield mushrooms that need to be harvested promptly when the caps open, no procrastinating... Perhaps there is a more humid environment in the bag, and thus a smaller window of time for harvesting the mushrooms than with other kits. I'm not sure, but this is a small matter – I will definitely be continuing to buy this great kit in the future. (Posté le 12/04/2024)
