WeeZPZ Grow Kit

The WEEZPZ Grow Kit is similar to our EZPZ grow kit, except the tub is a different shape and it comes with no injection port - meaning this is for the people who know how to work clean and have some experience under their belts. You need a SAB with this. We offer a grow tent with these or without, absolutely up to you - the price is the same regardless.

It's a fast, compact, all-in-one kit if you want it to be, or you can take the finished coloinsed cake and fire it into your own fruiting chamber.. At this price, you could have a dozen different species and variants of your favourite mushrooms all growing at once.

If you want to find out more about this kit, have a look at the regular EZPZ we made for beginners.

We'll have a picture up of this kit in the next day or so, many customers have been sent this kit as a 'sorry gift' for beaing late - a sneak peek into our latest grow kit offerings.

Included with the WeeZPZ Cylocybe Grow Kit

  • Sterile WeeZPZ
  • Humidity Fruiting Tent (the same bag the Weezpz is in!)
  • Sterile Needle
  • Chlorhexidine Alcohol Wipe (for wiping around rim and lid)
  • Hand Wipe

You will need

You will need 1ml of gourmet culture spore solution for this kit.

Is the WeeZPZ Grow Kit for me?

Do you have a SAB? Can you work cleanly? If so, then probably yes. It's for the experienced who know how to open a lid and inoculate without contaminating it - if it contaminates, there's a good chance it's a skill issue (or possibly a bad syringe).

BIG DISCLAIMER

We do not offer any sort of EZ-Replacement on this product, in fact, more than that - we won't even replace this product no matter what.Β  It's too easy to contaminate and we can't be watching people use it. The reason this product is priced the way it is, is because we don't need to cut holes on the lids and put injection ports on them, we can rattle these out as a result. If this is your first time growing mushrooms, stay clear unless you want a challenge and aren't going to be disappointed if you can't inoculate without contaminating the kit - you will be opening the lid of something which is sterile to inoculate it, meaning it could so easily contaminate (no first-timer is likely able to manage this without contaminating it).

EZPZ GROW KIT
INSTRUCTIONS

2026August 2026

We also recommend reading our troubleshooting guide before attempting any grow as it's full of useful information which will help you solve and avoid problems.

Step 1: Inoculation of Sterile EZPZ substrate

In this initial stage of mushroom cultivation, the goal is to inoculate the sterile EZPZ substrate with your selected gourmet mushroom spores or culture. This process involves preparing a spore/culture syringe and injecting a specific amount of this solution into the EZPZ, our specialized container designed for mushroom growth. It's crucial to maintain a clean and sterile environment throughout this process to prevent any contamination. Also, it's important to ensure the correct amount of spore or culture solution is used, and essential components of the EZPZ, like the air exchange filter, remain undisturbed.

  1. Prepare for the process: First, ensure cleanliness to avoid contamination. Use the blue Clinell wipe provided to thoroughly clean your hands and forearms.

  2. Prepare the mushroom spore/culture syringe: Get your gourmet mushroom spore or culture syringe ready. Attach a new, sterile needle by screwing it onto the syringe.

  3. Clean the injection port: On the lid of your EZPZ, you'll find a grey rubber injection port. Use a green Clinell wipe to clean this area.

  4. Be cautious of the pink filter strip: You'll notice a pink filter strip on the lid of your EZPZ. This strip is crucial for maintaining clean air exchange, so don't touch it or attempt to remove it.

  5. Inject the solution: Pierce your needle through the cleaned grey injection port. Aim towards the edge of the EZPZ, then slowly inject 3ml of your spore or culture solution. Please be careful not to exceed 3ml to avoid overfilling.

Step 2: Colonisation of Sterile EZPZ substrate

Step 2, colonisation of the sterile substrate, is where you'll start seeing signs of growth from the mycelium, the root structure of your mushrooms. During this stage, it's essential to provide an environment that's conducive to mycelium growth. This means storing your EZPZ in a place that's not airtight - the EZPZ's original cardboard box is perfect for this. One of the critical factors to monitor is temperature; holding a steady 23C (give or take a couple of degrees) helps avoid problems like contamination or slow growth. While it might be tempting to use heat mats, we advise against it due to potential uneven heat distribution and excessive condensation. If you're having trouble maintaining the right temperature, consider using an incubator for better control. With these conditions met, you should see mycelium growth in 4-5 days, and potentially achieve full colonisation within 14 days.

  1. Don't suffocate your Mycelium: Your Mycelium is a living organism and needs to breathe. Avoid placing your EZPZ in an airtight container.

  2. Use the box for storage: The cardboard box that your EZPZ arrived in makes a perfect storage spot. It will help to keep your colonising EZPZ clean.

  3. Keep an eye on temperature: Temperature plays a significant role in successful colonisation. Avoid temperature extremes; too hot (above 26Β°C) or too cold (below 18Β°C) can lead to problems, like contamination or slow/no growth.

  4. Maintain consistent temperature: Aim to keep a stable temperature of 23C (give or take a couple of degrees). Avoid frequent or drastic temperature fluctuations.

  5. Say no to heat mats: Heat mats can lead to uneven warming, causing excessive condensation. This could result in water buildup, inviting contamination into your EZPZ.

  6. Consider an incubator: If maintaining the right temperature is difficult, think about creating or purchasing an incubator. It's more cost-efficient than constantly heating your home and yields better results.

  7. Wait for growth: At 23C (give or take a couple of degrees), expect to see mycelium growth in about 4 to 5 days. After this point, the growth rate will increase significantly.

  8. Full colonisation timeline: With optimal conditions, your EZPZ could be fully colonised in 14 days. We've tried it ourselves!

Step 3: Fruiting your Mushrooms!

In the third stage of the mushroom cultivation process, we transition from mycelium colonisation to mushroom fruiting. Once your EZPZ is fully covered in white mycelium, it's ready to be prepped for this fruiting phase, which begins with a process known as 'dunking'. Dunking involves hydrating the substrate to stimulate mushroom growth. After this, the EZPZ is moved to a grow tent where conditions such as temperature and humidity are carefully managed. There's no need for misting in this stage; the natural humidity generated within the grow tent will suffice. Harvesting your mushrooms comes next when the veil beneath the mushroom cap is about to tear. After the initial harvest, the dunking process is repeated to stimulate further flushes of mushroom growth. With appropriate care, your EZPZ can produce multiple flushes until the substrate nutrients are exhausted.

  1. Wait for full colonisation: Wait until your EZPZ is entirely covered in white mycelium - that's when you know it's fully colonised and ready for the next step.

  2. Prepare for 'dunking': 'Dunking' is a method used to add moisture to your substrate to prepare it for fruiting. Fill your EZPZ (with the colonised substrate inside) with water, then secure the lid. Leave it for 4-6 hours before draining all the water.

  3. Move to the grow tent: After draining, remove the lid from your EZPZ and place it in the grow tent. Seal the tent's opening with selotape.

  4. Manage temperature: For the fruiting stage, keep the temperature slightly lower than your incubation temperature, ideally 21C (give or take a couple of degrees).

  5. Humidity is key: At the right temperature, humidity will naturally increase inside the grow tent due to the water soaked into the substrate. This is crucial for fruiting.

  6. No need for misting: Unlike some other kits, you don't need to mist this one. Only open the tent when it's time to harvest your mushrooms.

  7. Harvest time: When the veil under one of your mushroom caps is about to tear, it's time to harvest your first flush. Use a clean scalpel or knife to cut the mushrooms off.

  8. Repeat the dunking process: After harvesting, add more moisture to your cake by filling the EZPZ with water and leaving it for 4-6 hours. Then drain the water. If you've misplaced the EZPZ lid, use tin foil or cling film as a cover during soaking. After draining, place the EZPZ back into the grow tent.

  9. Expect multiple flushes: Continue this dunking process after each flush. With proper care, you should be able to get multiple mushroom flushes from your grow kit until all nutrients are used up.

Additional Tips for Enhanced Mushroom Growth:

In addition to the main steps of growing mushrooms with our kit, there are several other practices that can enhance your results. Central to healthy mushroom development is a balance between humidity, fresh air exchange (FAE), temperature, and light. You can increase FAE by making small slits in your grow tent and using a fan to circulate air gently within the room. Providing indirect sunlight or using an LED/fluorescent light with a specific wavelength can also help mushrooms grow optimally. If your grow tent seems dry, there are various adjustments you can make, such as adjusting the environment's temperature or the position of your fan or grow lights. Within a week of entering the grow tent, you should see small white dots known as hyphal knots, which will develop into mushroom pins. Keep a close eye on your mushrooms' growth and adjust your setup if needed, especially the level of FAE. It's all about observing and making necessary tweaks to achieve that delicate balance for optimal mushroom growth.

  1. Achieving the best results: For healthy mushroom development, maintaining a balance between humidity, fresh air exchange (FAE), temperature, and light is key.

  2. Increase FAE: To enhance FAE, make a 1cm slit on both sides of the grow tent, near the top. Position an electric fan in the room on a low setting, which will stimulate a gentle air current and increase FAE inside the tent.

  3. Provide sufficient light: Provide indirect sunlight or place a 6-7000K LED/fluorescent light a couple of feet away. This will give your mushrooms the necessary light for optimal growth.

  4. Troubleshoot dry conditions: If your grow tent seems dry, it could be due to the following:

    • Too cold of an environment, preventing humidity from developing.
    • The fan being too close, thus drying out the tent.
    • The slits in the grow tent being too large and allowing too much humidity to escape (in this case, use tape to reduce their size).
    • Grow lights being too close and generating excessive heat.

  5. Watch for the first signs of growth: After 3-7 days in the grow tent, you should see tiny white dots (hyphal knots) that will develop into primordia (the precursor to mushroom pins).

  6. Mushroom development: It usually takes another 4-5 days for these pins to grow into mature mushrooms. Keep an eye on their progress; they'll let you know if conditions aren't right.

  7. Adjust FAE if needed: If you see fuzzy mycelium at the base of the mushrooms or thin stems, you may need to increase FAE. Try increasing the fan speed or enlarging the slits in the bag.

  8. Observe and adjust: The fruiting stage requires careful observation. Adjust your setup as needed to maintain the balance of humidity, FAE, temperature, and light.
