Description

SPORTARC grow sponges are premium seed starter pods designed for reliable germination in hydroponic systems and indoor gardens. Made from biodegradable sphagnum peat material, these 100 sponge plugs provide an ideal growing medium for seedling development and root growth. Each pod measures approximately 1.97 inches tall and is pre-dried to prevent mould, ensuring healthy plant establishment. The sponges work seamlessly with hydroponic indoor gardens, grow baskets, seed starter systems, nursery trays and potted plants for both indoor and outdoor use. Simply remove the old sponge and replace with a new one - no tools required. After rooting develops, seedlings transplant easily into soil. This comprehensive kit supplies sufficient degradable sponges to meet regular gardening needs whilst supporting sustainable, chemical-free germination for serious growers.
