Alternative containers for mushroom growing
Growing mushrooms without wide-mouth mason jars is entirely feasible, and the choice of container can significantly impact yield, ease of maintenance, and overall success. Alternative containers range from everyday household items to specialized grow kits, each with unique advantages. For instance, plastic storage containers with adjustable lids offer better humidity control compared to glass jars, as they allow for more precise airflow regulation. This is particularly beneficial for species like oyster mushrooms, which thrive in high-humidity environments but require periodic fresh air exchange to prevent contamination.
When selecting a container, consider the mushroom species and its growth requirements. For example, shiitake mushrooms often grow well in perforated grow bags, which provide adequate ventilation and drainage. These bags, typically made of breathable polypropylene, are ideal for bulk substrate methods and can be hung vertically to save space. Similarly, cardboard boxes lined with a plastic bag create a simple, cost-effective fruiting chamber for species like lion’s mane, which prefer darker, enclosed spaces. The key is to ensure the container supports the mushroom’s need for moisture, air, and light while minimizing the risk of mold or pests.
For those seeking a more sustainable approach, repurposed materials like large plastic bottles, yogurt containers, or even coffee cans can serve as viable alternatives. A 2-liter soda bottle, cut in half and reattached with tape, makes an excellent mini-greenhouse for growing enoki mushrooms. Simply poke small holes in the cap for ventilation and fill the bottom with sterilized substrate. This method not only reduces waste but also allows for experimentation with different container sizes and shapes to optimize growth conditions.
However, not all containers are created equal. Avoid materials that may leach chemicals or retain excess moisture, such as untreated wood or certain metals. Additionally, containers with sharp edges or uneven surfaces can damage mycelium during colonization. Always sterilize or sanitize containers before use to prevent contamination, and monitor humidity levels closely, especially in non-traditional setups. With creativity and attention to detail, alternative containers can unlock new possibilities for mushroom cultivation, making the process accessible to growers of all skill levels.

Mushroom cultivation in Tupperware containers
To begin, select a food-grade Tupperware container with a secure lid. Sterilize the container by boiling it in water for 10–15 minutes or using a 10% bleach solution followed by a thorough rinse. Prepare your substrate (e.g., straw, sawdust, or grain) by pasteurizing it at 160–180°F (71–82°C) for 1–2 hours to kill competing organisms. Allow the substrate to cool before inoculating it with mushroom spawn, using a ratio of 1:5 spawn to substrate by weight. Mix thoroughly, then transfer the mixture into the Tupperware container, leaving 1–2 inches of headspace for mycelium expansion.
Ventilation is critical when using Tupperware, as its airtight nature can trap excess moisture and CO2. Drill or punch small holes (1/8–1/4 inch) in the lid to allow gas exchange while maintaining humidity. Place the container in a dark, temperature-controlled area (60–75°F or 15–24°C) for colonization, which typically takes 2–4 weeks. Once fully colonized, introduce light and reduce humidity slightly to trigger fruiting. Mist the container’s interior daily with filtered water to maintain moisture without oversaturating the substrate.
Compared to mason jars, Tupperware containers offer the advantage of easier substrate mixing and less risk of breakage. However, their plastic composition may degrade over time with repeated sterilization, limiting long-term use.
