Jack Frost Cloud920® XL Ready-to-grow bag
Jack Frost Magic Mushrooms, a strain of psilocybe cubensis shrooms known for its high potency and distinctive appearance.
The Jack Frost shroom is a cross-breed of True Albino Teacher and Albino Penis Envy, both strains famous for their beauty and potency.
Jack Frost is aptly named because of its frosty appearance, pure white mushrooms with flat caps that curl upwards when they mature.
Be advised: this is, without a doubt, the strongest psilocybe cubensis in our catalogue. Adjust your dose proportionately.

Strong and good yielder (Posted on 12/24/2025) - Slightly Disappointed Review by Miguel
-
I’m a bit disappointed with the Jack Frost Cloud 920XL so far. The mycelium looks very healthy and strong, which initially made me quite excited. However, after 4 weeks, the mushroom growth has been very slow. Up to now, only two mushrooms have developed to a reasonable size, and the others are still very small with no significant progress.Rating
I’ve been opening the bag about once a month to try to stimulate growth, but unfortunately the results are still below my expectations. Overall, I was hoping for a more consistent yield from this product. (Posted on 12/7/2025) - Jack Frost - Great Product Review by C-Mush

All good so far, but this is one for the patient cultivators. Jack frost is notoriously known for its slow pinning but it pays off as the strain is very potent. Mine just started pinning after weeks of waiting. Can't wait till they mature and harvest! Thank you MMS for your amazing service. (Posted on 11/19/2025)Rating - Awesome Review by MG

I have bought a couple times from mms now and the products are always amazing, the troubleshooting is immediate and the products are TOPRating
I started this kit since 3 weeks and no fruits yet but JF are tipically slow to fruit and grow but the mycelium is looking healthy and I just can't wait! Of course some grow kits are not going tò be perfect but the MMS customer care will solve everything for you!
Buy once, buy always from them
Thanks MMS (Posted on 11/12/2025) - easy to use Review by Matjaž

It took 14 days to reach the first pins, then I waited 11 days for the first harvest, which yielded 110g of wet mushrooms. Now I’m drying them and hoping the second flush will appear soon.Rating

-
My only complaint would be that the kit doesn't seem to yield as much as expected, I'm still hoping for a third flush to get a little more out of it.Rating
Support has been great though, they really seem to care :) (Posted on 11/5/2025) - Great medicine Review by Bitok

Great medicine, very good ! Initially crops were bigger but nevertheless they’re great! (Posted on 10/31/2025)Rating - happy with everything. Review by Sorongil

Aw a 1st time grower, made some mistakes at the begining stages, contacted the support, and I can't say enough praise for those guys. By following their advice, I managed to save 80% of the order. Deliver is fast and reliable to the max. Definitely ordering again since yield and potency were excellent after all the mistakes I made. Can't wait to write a review again once I do it right from the start, it's actually happening right now since they even sent me a replacement for a suspicious bag of Jack, but even that bag yielded some, and the replacement bag is progressing real nice now that the conditions are tweaked with the help of the support staff here.

Thanks for the waffle nice touch!! Product is good (Posted on 10/30/2025)Rating - Top strain and great service Review by Thomas
-
I had a couple of those. I only had one that did not work and it was replaced as M-M-S customer service is great. The others worked as expected, yielded good and had it's effects as specified. A little more intense than standard cubensis with a deeper insight and transformation qualities. (Posted on 10/26/2025)Rating - Beautiful! Review by Yanou

Very easy to grow and very resistant to molds!Rating
I have used no clip to spray it lightly once every 2 days and to give it more air exchange once a day.
Vigorous mycelium which is taking his time for fruiting but the result is great!Maybe a good idea to get it in a monotube!
A very big thanks to Lottie for her kindness when you have a problem!
This is the place! (Posted on 10/23/2025) - The first one didn't meet expectations Review by Toni
-
I bought my first kit and my hopes and expectations were high. I read the instructions and reviews carefully and my expectation was that in 2-3 weeks the mushrooms would start growing and in 3-4 weeks I could harvest. However, after 3 weeks there was no sign of the mushrooms and then I started giving them air once a day and kept the kit in the fridge for one night. Then after 4 weeks the first pin was born. Now after 5 weeks and 3 days I harvest 123g of wet mushrooms. The support team has been great throughout the whole process, but my expectations were not met in the end result, which I am a little disappointed about. Maybe the Jack Frost growing instructions could have been written that it is quite normal for the variety in question to grow for 5-6 weeks, as support told me during the process. However, I have already ordered the next kit, albeit a different variety. (Posted on 10/21/2025)Rating - Slow and strong Review by Stray
