Grow your own Oyster Mushrooms! Growing your own mushrooms is a truly extraordinary and satisfying experience and the fruits of your fun are delicious and nutritious. A Mushroom Factory also makes a great gift idea. To maintain your mushroom factory all you have to do is add water, a bit of light, and love.

Mushroom Species : 

  • Pleurotus ostreatus, Grey oyster mushroom strain HK35

Ideal Growing Conditions
There are four essential Ingredients that will ensure you get the most out of your Mushroom Factory, they are:

Light- Oyster mushrooms need light to grow. Place your oyster mushrooms in a well lit area- but not direct sunlight! The rule of thumb is that if there is enough light for you to read in, there is enough light for your mushrooms to grow.

Temperature- The best temperature for your mushroom factory is between 18-20 degrees. Your kit can also produce mushrooms between 12-25 degrees, but it will do better if kept in the 18-20 degree range.

Water- Water your factory by misting water on to the window and the humidity tent surface 2-3 times a day.

Air- Good movement of air is important for healthy mushroom growth. You will soon see if your mushrooms aren't getting enough air - they will develop long spindly stems and small caps.

Harvesting Your Mushrooms

  • Pick the mushrooms while the edges of the caps are still curled down. If you leave the mushrooms to grow bigger, you will end up with poorer quality mushrooms and it also means fewer mushrooms later on.
  • Pick all the mushrooms at the same time by twisting them off at the base. Be careful not to pull out the substrate.
  • Don't cut the mushrooms off at the base, this is going to make the stump rot - a rotten stump means fewer mushrooms on your next flush.
  • Once you have picked your first flush, keep on watering your Mushroom Factory. Your factory should produce between 2 and 4 flushes of mushrooms. Your most successful crops are usually the 1st and 2nd because this is when there are the most nutrients for the mushrooms to feed off.
  • From the time your mushrooms start growing, they should double in size every day. They will be ready to pick after about a week.
  • From start to harvest it generally takes between 14-21 days

Disposing of you kit
These mushroom kits are RECYCLABLE! When your mushroom factory has finally exhausted itself, enrich your compost with it.

So your Mushroom Factory has worked long and hard, and has been a great success and you have more mushrooms than you know what to do with. Don't let these delicious mushrooms go to waste. Here is how.

Store some in the fridge for this week's delicious mushroom meals and preserve the rest. Mushrooms can easily be dried or frozen for future use. Lucky you, because you have grown your own oyster mushrooms, you know they aren't filled with grit and grime. If you want to give them a quick wipe before cooking, use a damp paper towel. Be gentle and try to avoid getting them wet. Mushrooms may love humidity when they are growing but not once they are picked.

Storing your Fresh Mushrooms

  • Your mushrooms will keep up to a week in the fridge.
  • Mushrooms should never be washed before being stored.
  • Once you've picked your mushrooms, wrap them in a damp (not wet) paper towel and put them in a brown paper bag. (This stops them from drying out).
  • Keep your mushrooms at the bottom of the fridge with the other veggies (It isn't as cold as the rest of the fridge).
  • Don't store your fresh mushrooms in airtight containers - they cause condensation, which will make your mushrooms soggy.

Preserving Mushrooms - Drying

  • Stored properly, dried mushrooms have a more potent flavour than fresh ones, so you will use less dried mushrooms vs. fresh.
  • A kits yield depends very much on how well the kit is taken care of – each kit should yield 4 flushes – flushes get smaller as the Cellulose gets used up.
  • On average our kits produce about 500gr over the cycle of the kit

Directions for Drying

  1. Pre-heat your oven to 150°.
  2. Slice your mushrooms into slices about ½ cm. The thicker the slices, the longer they take to dry out.
  3. Arrange your sliced mushrooms on baking trays in a single layer.
  4. Bake your mushrooms for 1 hour and remove from oven.
  5. Use some paper towel to gently dab any moisture that sweated out from your mushrooms.
  6. Turn your mushrooms over and cook for another hour.
  7. By now your mushrooms should be completely dry. If not, repeat Steps 4 and 5 until they are dry.
  8. Allow them to cool, and then store them in an air-tight container in a cool, dark place.
  9. Your mushrooms are ready to store when they feel dry when you touch them. They should still be flexible. A good idea is to add a wad of paper towel at the bottom of the jar - just to absorb any moisture that might still be lurking around.

To Rehydrate
Put your mushrooms in a bowl of warm water for 30 minute or if you are in a hurry, bring a pot of water to the boil and simmer your mushrooms for 10 minutes. Keep this liquid for stocks, soups and sauces by pouring the liquid into an ice tray and freezing. When you need it, just pop the frozen stock into the pot.

Freezing Mushrooms
Freezing your mushrooms will allow them to keep their great flavour, but freezing leaves you with a soggier looking mushroom. Frozen mushrooms are ideal for soups, stews and casseroles.

Using the method below your mushrooms should keep for about a year.

  1. Bring 1 l of water to the boil with ½ a teaspoon of Salt.
  2. Add mushrooms and bring to the boil again.
  3. Boil for another 3 minutes.
  4. Rinse with cold water.
  5. Drain thoroughly.
  6. Seal in freezer bags.
  7. Freeze.

Recieved package very quickly.
It's been only 8 days and little mushies are poking through! :)
08/06/2022, By Lili
Epic gift for mushroom lovers! Easy to set up and waiting patiently to get our first flushes of mushies.
16/05/2022, By Ali
I have had my kit for 5 weeks now and have followed instructions precisely. I have had absolutely no mushroom, in fact it doesn’t even look like there is even mycelium in my pack. The packet had quite a few little holes pocked through from the time I got it, and it looks like their is possible mould growing(black stuff) plus on the side it said use before a date in February, but I only received the kit in April? I’m pretty sure I just wasted my money!
11/05/2022, By Vickie
I got this about 10 days ago and I have already had 2 bunches of mushrooms that are big enough to harvest. It remains to be seen whether I get any more harvests out of the kit, but it's been great fun so far! The mushrooms that I have harvested are delish.
15/12/2021, By Chris
We had good success with this at the start, and harvested after a few weeks. Sadly since then no more mushrooms have grown, which seems to coincide with other people's experience. Such a pity.
20/11/2021, By Chris
Early days, let's see how we go in a couple of weeks. Easy to set up though.
10/05/2021, By Lynn
Love the concept and price on this site very good compared to other sites. Great to be able to pick as they grow
09/04/2021, By Adri
Quick delivery, excited to start it.
Only downside was the product expired / best use before date is a few weeks after I bought it and I had in mind to give it as a bday gift a few weeks after that date... hope it still works
24/03/2021, By Nichola
Be persistent and patient with your mushrooms. Follow the instructions carefully, and continue to spray with water even when you think there is no sign of life. We eventually had three flushes and it gave us months of fun. We also enjoyed the garlicky mushrooms in olive oil for suppers.
15/03/2021, By Meagan
The kit is such a stunning idea. I got it for a friend who loves mushrooms and loves growing plants, and she loved it! Would definitely buy it again
12/03/2021, By TonyH
In the kit provided, i.e. “The Mushroom Factory - Oyster Mushroom Kit” there were no Oyster Mushrooms at all!! I do not know the name of the mushroom which we got - a white/light grey capped mushroom. We do not even know if this is even safe to eat??
19/02/2021, By Michi
This is an update of my previous rating. The mushrooms grew! After four weeks of spritzing with water twice a day...I had almost given up. Glad I kept going. These oyster mushrooms look awesome.
15/02/2021, By Michi
Followed instructions, misted twice a day or three times on hot days. Absolutely nothing has sprouted from the box in two weeks. What a disappointment. I sent The Mushroom Factory an email but there was no response.

Lovely as a gift... friend was super excited to grow her own mushrooms:)
30/12/2020, By Timika
This is the second time I have ordered this. It makes such an awesome gift that isn't too expensive either!
10/12/2020, By Heidi
I bought two, one as a gift, one for myself. My friend was ecstatic and started straightaway. Ate her first mushrooms within 2 weeks.

I started mine 2 days after the best by date. Waited for about 10 days, nothing happened. Then suddenly there were the first buds. They grew so fast. Then they shriveled and dried up. I stopped misting, because I thought it was a failure. Then, one morning there were a big mushroom and some new buds. It was delicious. Now misting my second flush.

I bought this as a gift for my father in law, he is sooo tough to gift, but this went down so well. He loved it and loved eating his mushrooms! It didn't have tons of mushrooms on the first flush but enough to enjoy, and the 2nd flush has been even less. Hoping to have a 3rd flush... If gifting I would suggest order it as close to the gift giving time as possible as the mushrooms can start growing by themselves.

28/10/2020, By Deborah
As some of the other reviewers have said, I didn't get any mushrooms, only mould, although I followed the instructions. I'm not sure about how sterile it was as some of the spawn or substrate had leaked through the bag when it arrived. I think that it is a case of caveat emptor - if you buy this be prepared for a bumper crop or nothing. I would not recommend this for a gift or for growing with children as it could be a big disappointment. I might try it again but would need to wait for cooler weather now.
26/10/2020, By Samia
Great product

I don't have green fingers..did not water it 3 times daily and 5 days later ate my first serving of mushroom. Totally idiot proof and so much fun! Best buy ever!
30/09/2020, By Ray
I tried this for the first time and am thrilled to have a lovely harvest of beautiful mushrooms. Getting started and growing is a very easy process. I was diligent about keeping moist daily. Wouldn’t be possible if I was traveling as usual. Ideal gift for children.

Awesome results
03/06/2020, By Tara
It's a fun thing to see how mushies grow but I wouldn't say that the yield is that great, especially the final one. Enjoyed it but probably wouldn't buy it again.

LOVE this product! So much fun growing them and interesting too, kids loved it and all the people we gifted it too, a smash hit! Amazing to watch them grow.
23/02/2020, By Anne
It worked beautifully! and the mushrooms taste even better, when you "produce" them yourself. not sure if you save money, but it is a lot of fun if you enjoy growing your own fruit and veggies.
24/01/2020, By Quest
Try it
17/01/2020, By Timika
Bought this as a gift for someone who is hard to buy for and it was the best gift ever! She has absolutely loved it and is on her second flush of mushrooms. Would definitely order this again!
15/01/2020, By Ang
I bought this kit as a gift. My friend was thrilled UNTIL he read ‘this kit was lovingly made on 26/9. For best results use kit before 1/11/2019. I only bought this kit before Xmas on 19/12. Why are you selling kits that are past their best result date!? And probably because it wasn’t before the best before date, my friend only enjoyed one bloom of mushrooms despite the box suggesting 2-3 blooms. I feel cheated - rather be honest and tell me I’m about to buy a product that it has already passed its best by date.
07/12/2019, By Deno
Grew much faster than I expected.
11/11/2019, By Camilla
The instructions were very straightforward and it was such a simple process to grow these beautiful oyster mushrooms! I'm very happy with the result :)
29/10/2019, By Mike
I'm interested in growing oyster mushrooms please help to start
25/10/2019, By Caro Lune
So far so good, my gorgeous mushrooms are growing beautifully! Such an exciting process.
23/10/2019, By Mariek
I am going to give it a go fingers crossed
14/10/2019, By shalla CM
All the info needed to grow your own mushroom is included in the kit. Very easy to set up. Awesome Kit
27/09/2019, By Rob
Been misting and waiting and noticed today that my shrooms are starting to grow. When they grow do you still need the misting tent or will it get in the way as the mushrooms grow?
11/09/2019, By Binky
Super cool, mushrooms grove just as explained on the packaging. Easy step steps to follow and reliable.
27/06/2019, By Madam Vee
This didnt work for me at all. Followed all instructions but all i got was mould! What a waste :(
14/06/2019, By christiaan
Bought another box.. waiting to see still what happens but started growing already before opening the box.. little bit dissapointed but still confident about getting a decent harvest..
03/06/2019, By christiaans
This was stupidly easy to grow... not rocket science at all..
Kept it in a room, curtains drawn, but enough light and sprayed it every second day...
24/04/2019, By Ilana
Also, the only thing that grew was a brown contaminant fungi from the bottom. Very disappointed.
04/04/2019, By Andy
Bought this over a month ago and all i got was a brown streak down the front. Definitely wont be doing this again
27/03/2019, By TheOak
Fun to grow and taste great!
15/03/2019, By Sarah
I loved this product! So easy to use. I tried to grow it in Durban summer however so struggled to get the right climate. Even so I got three decent yields of huge happy mushrooms. A wonderful gift for a mushroom lover
11/03/2019, By Melissa
Bought this for a friend and he is loving the whole experience. Thanks for a cool gifting option!
01/02/2019, By Diane
My order arrived before I expected it to - thumbs up to that.
Still waiting for my mushrooms to appear but have high hopes as it is only 6 days now.
Perhaps Mushroom Factory could put a warning on the outside of the box about removing the outer plastic bag in the box.
Another review spoke about it so then I checked mine.
29/01/2019, By EGL
Followed instructions to the letter - all that happened was straw turned different shades of mould. Not a mushroom in sight. Waste of time, effort and money. Threw it away.

I bought this for my boyfriend down in Cape Town, coincidentally someone gave it to me as a gift up in joburg... each of us followed the instructions and have seen no results... no mushrooms whatsoever... I don’t think the growing process is as easy as one might think... so be mindful of that before you purchase this!
19/12/2018, By Karin
This was my first ever product I've bought from Faithful to Nature and... IT'S AMAZING! Love it!! Now that I saw it's price is a bit less I'm going to order again!! Love these mushrooms and love the "dyi-process" to bits!!
09/09/2018, By Carli
I got this for my mother as a birthday present and she is loving the process. Can't wait for the mushrooms to grow!
03/09/2018, By M
I bought this as a gift, but I took over caring for it as it was just so much fun. We harvested our first flush recently and the mushrooms were delicious. This is a good gift for an adult but I imagine it would also be a fun project for children. One improvement would be to tweak the instructions for use slightly and have the illustrations be a little clearer.
28/07/2018, By Shan
I had so much fun with this, worked really well! Only wish there was a way to do this with less plastic
23/07/2018, By Martie
Excellent i will be ordering again soon!!!!!!
25/06/2018, By Marli
I bought this as a gift for a friend, but when it arrived it was so much bigger than I expected. I got too excited and decided to keep it for myself. The stress of the last minute gift hunting for a new gift was worth it. This kit is great, simple to use and produces massive and loads of mushrooms. I'm harvesting my first batch tonight for some risotto and I cannot wait.
24/01/2018, By Theresa
I bought my kit on 20 December and started it on 2 January taking meticulous care with the light, humidity and temperature requirements. To date there has been no activity in it. I took a closer look at it last night(23.01.2017) and saw the mulch was contained in 2 plastic bags and the outermost one had water in it that smelled awful. I removed that bag but I'm not hopeful that I will get any mushrooms.
15/12/2017, By Janet
This is the most amazing gift, product, or process to experience!! And they just keep regrowing! The trick is to allow a 'rest period' in which a little container of water sits at the bottom of the bag, but don't spray. And once the little musrooms start growing, then mist/spray again to keep things moist. LOVE IT!!! Definitely buying again and again once it's in stock again.
12/12/2017, By Liz
Great product, worked well and tasted great. The second time this was ordered, it stood for a few days before anything was done to it and there were already mushrooms coming out of the box, don't think this was supposed to happen.
27/11/2017, By Diane
I really enjoyed this product. It grew amazing mushrooms that tasted great. I appreciated Faithful to Nature's customer service as well. The boxes they had in stock started to grow in the warehouse so they ordered more so that I would be able to get a new, unsprouted product. Well done!
30/10/2017, By Megs
I loved playing around with these badboys. They're great as is, for a complex, chocolaty snack or addition to smoothies.

I also roasted and ground some to make my own chocolate - so yummy and interesting to work with.
20/10/2017, By Lucia
I did not have much success, will re-order and try one more time before I either win or give up with this kit.
07/10/2017, By Janet
So far so good... Following the instructions, and will see how much it grows! There's a small green moldy spot, which were there already when I opened the box - hopefully it won't have a negative effect?
03/09/2017, By Ann16
Lovely product, would purchase it again
19/07/2017, By SHARLET
It was an exciting thought to grow your own mushrooms but mine did not work well. I got one mushroom each week. I left the box untouched for a week after delivery and a mushroom grew out from the back of the cardboard box.
02/07/2017, By Ayanda
Growing mushrooms for the first time, I enjoyed the experience
02/07/2017, By KATHERINE
This was a really fun and interesting product. The mushrooms were easy to grow and yummy to eat.
30/12/2015, By Tanya
We bought one as a gift and it was way bigger than I expected. There were a lot of oohs and ahhs at it was opened. Think I now need to buy one for myself.
