Beautiful! Review by Yanou

Rating

Very easy to grow and very resistant to molds!
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

Rating

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)

Great Albino Medicine Review by vitor

Rating

Great and profound mushrooms, initially crops were bigger now I’ve noticed they don't produce as much but, nevertheless, it has been ok! I love them! be careful with dosage, for me they are not for recreational use but yes for cerimonial use! (Posted on 9/2/2025)

11/10 Overall. Very easy to grow and quite fast-growing too. Big, meaty mushrooms that hit way harder than regular P. Cubensis. Will definetely be back soon!! ;) (Posted on 8/18/2025)

Contamination resistance Review by Dave

Rating

I always learn or experience something new when growing shrooms. This time I received some Jack Frost kits with spots of green mold and I was afraid of opening it. Frank told me that they can survive if they get some fresh air and all of them fruited multiple timed :D
Amazing how strong they are! (Posted on 6/27/2025)

My first disappointment with Mushroom Shop Review by Dom

Rating

Unfortunately, my grow kit didn’t produce anything this time. I followed all the instructions carefully. It started off well, but in the end I only got two tiny mushrooms, about 2 mm each ????. Still, I remain loyal to the Mushroom Shop and I definitely recommend it!

Jack Frost feedback Review by Afonso

Rating

I just wanted to give a big thank you to Frank and the lovely team who helped me over email. The first kit I received didn’t go so well, but thanks to the amazing support from both of them, they sent me a new kit – and this one is an absolute beast! I’ve had some great harvests, all thanks to Frank’s tips – following his advice really made a difference.

I also tried growing the Thai mushrooms and they were surprisingly easy to cultivate. Super happy with the whole experience. Huge thanks again for the care, kindness and professionalism. Keep up the great work!

Be Patient and it will work Review by Alessandro

Rating

So this kit is very slow compared to the other growth kit .

My suggestion to make it perform are :

1) Don’t use the plastic clip they give you with the kit . I use it at the beginning and because it’s very heavy it will bend the bag and in particular the part where is located the filter will be blocked and doesn’t allow the air exchange . Use instead simple paper clip and let the bag on order to let the air come in and out the filter of it.

2) after 2 weeks open the bag once a day to speed up the growth process

Then wait and once the process is started the mushroom will grown without any problem :) (Posted on 4/4/2025)

Very strong mushrooms Review by Jon

Rating

I really love these mushrooms and want to share my experience.

I was told they were strong, but as someone experienced with high doses of LSD, I thought I was prepared. So, I took a heroic 5g dry. It hit incredibly fast, much quicker than any mushrooms or LSD I had tried before. The trip was unbelievably intense. For a while, I thought I was dead. I could see my thoughts and imagination play out without even moving from my chair.

Eventually, I regained awareness and started enjoying the trip. The visuals were absolutely phenomenal.

Moral of the story: take it carefully. I’d say 1g is enough. I totally recommend these mushrooms and this store.

Huge thanks to the team for their support during the grow. I will definitely buy again! (Posted on 4/2/2025)

Incredible shrooms Review by Brian

Rating

First flush took about 4 weeks to mature, although the mushrooms great at different rates so I was frequently harvesting only 1 big shroom at a time. In total I came away with just over 40 grams dried. Last flush was probably 8 weeks after receiving.

I take 2.5-2.7g in tea form and have very intense experiences with these, one trip was among the best I've had. I've shared with 5 other friends, all fairly new to shrooms, and all experienced intensely visual and introspective trips, so they've been properly tested.

This is my first timing growing Jack Frost and I will definitely order again. A couple notes: despite the instructions saying you don't need airflow, I reached out to support and they recommended giving them air once a day and that seemed to help them grow. Also, it appeared that contamination had set in but the shrooms still grew and thrives - apparently they eat the contamination. Incredible shrooms :) (Posted on 3/2/2025)

This one gave me a couple of abortions thats all Review by Lucas

Rating

They are probably realy Great but my first flush if i even could call it that just gave me a few abortions in the Corner of the bag! Not sure if the batch was bad on arrival or what happend always treat these babies with care in a sterile enviroment! But should perhaps load them into a box in the future and give them some air time to time! I dont know! Hoping to get some response from the lovely staff working here soon (Posted on 2/10/2025)

Easy, like True Albino Teacher, but mediocre yield Review by Stephen

Rating

First, I want to thank Frank for great help in my process, and for the recommendations.

Jack Frost is as easy to grow as TAT, but the one kit yielded 372g fresh, which isn't as much as the TAT kits. The potency of TAT tested at maximum potency (darkest compared with chart), but I'm still waiting on feedback.

I'm not sure if I'll try Jack Frost again. However, I'm very pleased with the great service MM provides. (Posted on 2/9/2025)

One big shroom, so far Review by Nina

Rating

The delivery was incredibly fast, which was a great start. I followed all the instructions that came with the kit, and after about two weeks, I noticed the first pin starting to grow. However, things seemed to stall with just that one pin, and no further development happened, so I reached out to customer support for advice.

I was pleasantly surprised by how quickly they responded! The team was super friendly, helpful, and full of advice. They explained that too much water had somehow accumulated and suggested I air out the grow box daily.

I'm now following their instructions and currently waiting for the second flush. So far, it's been a positive experience thanks to their support. (Posted on 2/6/2025)

Jack Frost Journey Review by Kiwi

Rating

A fun shroom to grow and good yield. First flush I got 3/4 oz dried and then on the second it grew a single monster - like a giant native tree - almost 1/2 oz dry weight!

Nice journey on these 2.0g - 2.5g has dropped me in there fairly heavy a few times now. I've found them to be less colourful in the outside world but takes me very very deep within my own mind.... enter the matrix! Gentle and smooth transitions, really nice experience, and a bit like a box of chocolates... I've been in deep and heavy quite quickly but done with 2 hours at times, but then other times a 2 hour transition into it with a good few hours to follow. Highly recommend these for personal and spiritual discovery with a clear intent/purpose on the front end

And how good are the team here!!! Isaac the day I visited the store and Frank on the support desk if you ever need help - quick in response and super helpful - doesn't feel like a job for any of them.

I guess something wrong with my kit Review by Al'ass

Rating

As this one should be easy to grow and has a great reviews, I am so far dissapointed. Started doubting after a little more than 3 weeks of nothing happening, I followed support's advice and started airing them for a short time once a day, to fasten the process. In, let's say, one week more, a few caps started to show but I picked up only two of them today, meaning it took them more than a week to mature, but only about 3cms long, but really fat ones. Some are still showing, I haven't tried the effect yet, but all in all, after 6 weeks of patience it seems my kit won't give much of a harvest. (Posted on 1/21/2025)
