Product Description
Details
How do I store my mushroom grow kit?
For the best results, we strongly suggest you start the mushroom kit's growth process as soon as you receive it.
Where should I store my grow kit if I cannot start right away?
The key to preserving your mushroom cultivation kit is keeping it cooled, specifically within a fridge that maintains a temperature between 2°C and 4°C.
We urge you not to cold store your mushroom grow kit for longer than 2 weeks.
Avoiding contamination
It is vital to uphold sanitary conditions and avoid rule out infection of any bacteria, fungi, yeast, or other possible contamination sources from your refrigerator. For enhanced protection, insert the grow kit in a and seal it securely.
Instructions for your GetMagic Grow Kit
- 1
Wash your hands thoroughly and clean the outside of the growkit with a dry cloth. Remove the lid but save it for later.
- 2
Pour warm water (20°C) into the growkit until it reaches the brim, replace the lid and allow it to steep for a period of just 5 minutes.
- 3
Take off the top of the grow box and ensure the water is adequately drained. Allow the grow box to drain for about 10 seconds.
- 4
Add a cup (200-250ml) of warm water (20°C) to the grow bag and place the grow box on the bottom of the bag, in the water. Then, fold down the top of the bag and fasten it with two paper clips.
- 5
Place the mushroom grow kit in a place with an average room temperature of 20-25°C. Make sure the grow kit is not in direct sunlight, under a lamp or near a radiator/heat source.
Keep the grow bag closed for the first 2 weeks, or less until the first pins/small mushrooms appear. After that, you should open the kit at least once a day to refresh the air in the bag.
- 6
As soon as the first pins are visible (or two weeks after setting up the grow kit), allow some fresh air into the grow bag every day (for a few minutes) (press the walls of the grow bag together and then fill with fresh air) and then moisten the walls of the grow kit with a spray bottle. Pinheads or pins are the first visible forms of small mushroom caps.
- 7
You can harvest your mushrooms right before the membranes at the bottom of the cap start to release. While harvesting, gently hold onto the stem and twist it either to the left or right. Once the mushroom starts to loosen, you can pull it out.
- 8
Well done, the gathering of crops is finalized. You can now cultivate a fresh batch of mushrooms by redoing steps 1 through 7 once more.

- Helpful Support Line Review by AV

I purchased the McKennaii XL Growkit – GetMagic. After approximately 4 weeks no pins had formed and I had not opened the grow bag. I contacted the support line as I was concerned that the kit showed no growth. I received a response on the same day. The response suggested that I open the grow bag to release the CO₂ and let in O₂. This worked! Thank you. Since then, I have purchased a heat mat as the room where the grow kit is located is a little bit cold. Since buying the heat mat, the growth has been amazing and I have just harvested a very good crop. Thank you for all your help and support.

I really appreciate the discrete packaging and the good customer support received. With regards to the product itself, I was very satisfied with the productive flushes and the overall effect.

Kljub natančnemu upoštevanju navodil je ta komplet popolnoma odpovedal. Gobe niso rasle in smo dobili samo 2 gobi. Ker nismo naredili nič narobe sem pisala na Support. Moram pohvaliti podporo strankam. Eni izmed najbolj prijaznih trgovcev. Zraven tega da se res hitro odzovejo, pomagajo in preverijo kaj je narobe, pošljejo zamenjavo. Ker Mondo ni več v XL, so poslali 2 mala kita Mondo. V primerjavi z get magic kiti je Mondo absoluten zmagovalec. Mondo kiti dajo najboljši donos, so preprosti za vzdrževanje, gobice pa so zelo kvalitetne. Od sedaj naprej bomo naročali le še Mondo growkits, saj so res kvalitetni.

Took a while to get going (3 weeks before it pinned) but once it did, it produced some beautiful fruits. A couple of 100g chonkers. Just harvested most of the second flush and have got 630g so far. Still a few more that'll be ready in the morning. So great results. Will prob get another 100 from a third and that's about as much as I could have asked for at the start. Sampled the fruits last weekend and they were awesome, lovely visuals and so much fun. The missus had her first trip and hasn't stopped raving about it since. She's in love! Would recommend. Thanks MMS (Posted on 8/5/2025)Rating - Super Review by Sherban

I suppose this was a multi-spore culture cause i seen some big variations from one to the other, however i isolated the genetics of 2 absolutely huge mushrooms, around 25 cm long...... Never seen such genetics :)Rating
For now I'm at the 3rd flush and got 50+ grams dry from 2 flushes.
Super decent, considering it's summer hot and i stored the cake 2 weeks more than i should have, initially. This dried it out a lot, but recovered greatly.
3rd flush is presenting 40+ smaller pins. (Posted on 8/5/2025) - All Perfect Review by Nicolás

I got just two tiny flushes and shrooms grew only from side, nothing from the top, the temperature was kept 23degC all the time. Very disappointing this time as I got quite good results with the previous set. (Posted on 5/14/2024)Rating - Very Satisfied Review by Daniel

(Posted on 5/12/2024) - Velik donos, močno potovanje Review by Metka
-
Zelo zadovoljna tako s storitvijo, kot s samimi gobicami. Te gobice rastejo in rastejo. Kar ni konca in to je super. Izlet s temi gobicami je bil duhoven. Imeli smo ceremonijo, kjer smo potovali vase. Pri zaprtih očeh so bili močni vizualni učinki. Kar nekaj podzavesti se je prikazalo. Tudi čustva so bila intenzivna. Priporočam!

The kit wasn't fully colonized when it arrived. It took about six weeks to see the first pins. But other than the long waiting time, it's great. (Posted on 7/29/2023)Rating - Very Satisfied Review by Texastom
