How to Use the Do-It-Yourself Grow Kit Like a Pro
If you’ve been curious about growing mushrooms at home but weren’t sure where to start, this kit was made for you. The Do-It-Yourself Grow Kit from Fullsend Organicks simplifies the process without cutting corners — giving you everything you need to start cultivating, without all the sterile lab equipment or confusing setups.
This is one of our most beginner-friendly tools, but it’s also trusted by experienced growers who want flexibility and control. Here’s how to get the most out of your grow kit and avoid the common pitfalls that stop people before their first flush.
What’s Included in the DIY Grow Kit?
Every Do-It-Yourself Grow Kit comes with:
- A sterilized infused rye berry quart jar (injection port + filtered lid)
- A manure super mix substrate/casing bag for fruiting
- Step-by-step instructions
- A chance to choose your own genetics (if applicable and legal in your area)
This kit is best used with a spore syringe or liquid culture — both available separately.
If you’ve never grown mushrooms before, this kit is designed to help you build confidence from the first step.
Step-by-Step: How to Use It
Step 1: Inoculate the Jar
Clean your hands and the injection port with alcohol. Using a spore syringe or liquid culture, inject 1–2 cc into the jar through the self-healing port. Shake gently to distribute.
Step 2: Let the Mycelium Colonize
Store your jar in a dark place at around 70–75°F. Over the next 2–3 weeks, you’ll notice white mycelium spreading through the rye berries. Don’t disturb it — just let nature do its thing.
Step 3: Move to Substrate
Once the jar is fully colonized (100% white with no contamination), break it up gently and mix it into the manure super mix substrate bag. Seal the bag and let it rest for 5–7 more days.
Step 4: Fruiting Conditions
Once the entire substrate bag is white and colonized, it’s time to introduce light and airflow. This can be done by slicing open the bag or moving it into a fruiting chamber like a mini tub or greenhouse.
Step 5: Harvest
Within 7–14 days of fruiting conditions, you’ll start to see pins form. Let them grow until the caps begin to open, then harvest gently and dry if needed.
Pro Tips for First-Time Growers
- Avoid over-handling the bags or jars during colonization
- Keep temps steady — big swings slow growth

- Label your jars if running multiple genetics
- Patience is key — rushing the process usually backfires
