Our extra-large grow kits have 6.5lbs of certified organic mushroom mycelium in them, enough to grow 3+ pounds of mushrooms across multiple flushes. 
Just pull the cardboard circle off the back of the kit, mist it 2-3 times a day and you'll have your own crop of fresh oyster mushrooms in 5-10 days. All kits come with a misting bottle, humidity dome and detailed directions in the top of the box.

How It Works

Our grow kit boxes contain a block of mushroom mycelium, illustrated directions, a humidity dome and a misting bottle. Mycelium needs light, humidity and fresh air to grow mushrooms. So to use our kits, you pull the circular cutout off the back of the box, cut an "X" in the plastic underneath and create a humid environment around the cut.

You can use the included misting bottle and humidity dome (which is made from plant-based plastic) or you can set up a humidifier next to the kit for a lower-maintenance option. Within 5 days, you should start to see some growth and within 10-12 days you should be harvesting your first crop of oyster mushrooms!

We guarantee that'll get at least one crop of mushrooms out of our kits but it's possible to get much more. After your first harvest, replace the humidity dome and continue giving the mycelium a humid environment. Some of our customers have gotten up to 4 additional harvests from their kits.

After you receive the kit, you can store it in the refrigerator for up to 6 weeks or up to 2 weeks at room temperature.

How Should I Cook These Things?

Our favorite way to cook all wood-loving species of mushrooms here at Hodgins Harvest is a simple saute recipe we call Cook 'Em Crispy. You can follow the recipe below or click here for a more in-depth explanation.


1/2 LB Hodgins Harvest mushrooms

1-2 TB butter or olive oil

2 TB white wine or sherry

Sea salt


Heat butter or oil over medium heat. Slice the mushrooms or shred them apart with your hands into small pieces. Sprinkle lightly with salt and sauté for 10-20 minutes. Allow most of the moisture to cook out of the mushrooms until they’re brown and crispy around the edges. Add the white wine/sherry and cook until the added moisture evaporates. Enjoy!

Substrate Ingredients

Our grow kit substrate is made from a mix of hardwood sawdust and either organic oat screenings or soy bean hulls. There is a small amount of grain spawn in each block that may contain one or more of the following grains: millet, rye and sorghum.
