Lactuca sativa longifolia aka Cos Lettuce

Cos Lettuce’s native range is Worldwide.

Cos Lettuce should be watered regularly, allowing the soil to dry out between waterings.

Cos Lettuce loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

To ensure optimal growth, the Cos Lettuce prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

No extra humidity is necessary for the Cos Lettuce. Absorption of water by plants is primarily done through their roots, and soil watering is the most effective method to provide humidity to your plants.
