- Effortless growing — no lab equipment, no prior experience needed
- Multiple flushes — harvest two or more crops from a single kit

How to Grow Your White Oyster Mushrooms
This mushroom grow kit makes growing mushrooms at home truly simple:
- Open — Cut an X-shaped slit in the bag to create a fruiting window.
- Mist — Spray the opening with water 2–3 times per day to maintain humidity.
- Harvest — In 7–14 days, your White Oyster mushrooms will be full-sized and ready to eat.
Continue misting after your first harvest and the kit will produce additional flushes. Most growers enjoy two to three rounds of fresh mushrooms from a single kit.
What You’ll Harvest
White Oyster mushrooms are a kitchen workhorse. Their mild, slightly sweet flavour and tender, silky texture make them one of the most versatile cooking mushrooms available. Sauté them in butter or olive oil for a simple side dish, toss them into pastas and risottos, add them to soups and stews, or use them as a gentle, flavourful addition to omelettes and stir-fries. Unlike stronger-flavoured mushrooms, White Oysters complement other ingredients without overpowering them.
Ideal Growing Conditions
- Temperature: 15–21°C (59–70°F)
- Humidity: High — consistent misting keeps conditions ideal
- Light: Indirect natural light or ambient room light
- Location: Any indoor space out of direct sunlight — kitchen, basement, or bedroom
What’s Included
- Fully colonized White Oyster mushroom substrate block, ready to fruit
- Simple growing instructions

This was my first time growing mushrooms and I couldn't believe how easy it was. First flush came in 9 days and I got about 300g total from three flushes.

My wife bought the white oyster mushroom kit a couple weeks ago and we just had our first harvest! The mushrooms tasted fantastic and had great texture! I did not take pictures but will do next time! We're currently re-hydrating the growing block and are excited for our next harvest! Great product!

Growing our own mushrooms was so fun! It took a couple weeks to see any growth but as soon as we did, they were fully grown and ready to eat in less then a week! Out first flush was almost 10g. Once we harvested, we did nothing with the block, we were planning on soaking it and trying for another flush but we didn't have to! The second flush started growing on it's own! So exciting! Can't wait to try other kinds of mushrooms now!

I bought 4 kits 1 white oyster kit for myself and the other 3 for my girlfriend for our anniversary. Unfortunately my girlfriends Lions Mane and Pink oyster mushroom got contaminated with mold. I contacted through email originally but after a few days without reply I tried to text them and they replied instantly. They said they would send me replacement boxes. Unfortunately I did not get the boxes because they apparently got lost in the mail but Nature Lion was nice enough to resend the replacements and added another white oyster mushroom for my troubles. So far I was able to get two yields from my white oyster mushroom and my girlfriend got one yield from her black oyster.

I bought the pink oysters, they pinned and then turned a salmon color and did not grow any further. The Lions Mane on the other hand grew as it should. I cut X's in all sides and took it out of the box and covered it in a bag. It was delicious, trying a second flush.!
