Grow Gourmet Mushrooms at Home

Bring the fascinating world of fungi right to your kitchen with the Yellow Oyster Mushroom Windowsill Kit. This kit lets you grow Pleurotus citrinopileatus—the vibrant yellow oyster mushroom—indoors, making it a rewarding choice for gardeners and food lovers alike.

• Botanical Info: Yellow oyster mushrooms are prized for their delicate texture, mild nutty flavour, and striking golden colour. They thrive in controlled indoor environments and are well-suited to compact spaces like windowsills.
• Growth & Harvest: After planting, expect to see your first flush of mushrooms within 7–14 days. Each kit can yield multiple harvests with proper care.
• Care Requirements: Place the kit in indirect light (avoid direct sun), keep the substrate moist but not soggy, and maintain temperatures between 18–22°C for best results.
• Seasonal Interest: Unlike outdoor crops, this kit produces mushrooms year-round—no waiting for spring or summer!
• Mature Size: Each mushroom cluster typically reaches up to 15cm across when fully grown.

Planting & Care Guide

• Location: Choose a bright spot with indirect sunlight—your kitchen windowsill is perfect.
• Watering: Mist daily to maintain humidity; avoid overwatering as mushrooms prefer moist, not wet, conditions.
• No Soil Needed: The kit comes with everything required—just add water and watch your crop flourish.
• No Special Fertiliser: The included substrate is nutrient-rich, so no additional feeding is necessary.
• Pest-Free Indoors: Growing inside reduces risk of pests or disease compared to outdoor cultivation.

Usage Ideas & Companion Planting

• Add freshly harvested yellow oyster mushrooms to stir-fries, omelettes, risottos, or salads for a nutritious boost.
• This kit pairs well with other indoor herb gardens—grow basil, parsley, or chives alongside your mushrooms for a complete culinary setup!
• An excellent gift for aspiring gardeners or foodies looking to try something new indoors.
