{"product_id":"giant-duck-weed-spirodela-polyrhiza","title":"Giant Duck Weed Plant \"Spirodela Polyrhiza\"","description":"\u003cp\u003eGiant Duckweed Plant (Spirodela polyrhiza) is a fast-growing floating plant with larger, round leaves compared to common duckweed. Its bright green fronds create a dense mat on the water’s surface, providing natural shade and reducing algae growth by limiting light penetration. Easy to grow, it thrives in still or slow-moving water and quickly absorbs excess nutrients, improving water quality. Perfect for ponds and aquariums, it’s fish- and shrimp-safe, though it may need regular thinning to prevent overcrowding.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eUsage\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e-Float on water surface \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBasic information:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eDifficulty: Easy \u003c\/p\u003e\n\u003cp\u003eUsage: Float on surface \u003c\/p\u003e\n\u003cp\u003eCO2: Not required \u003c\/p\u003e\n\u003cp\u003eLighting: Low-Medium\u003c\/p\u003e\n\u003cp\u003eGrowth: Fast\u003c\/p\u003e\n\u003cp\u003ePropagation: Sideshoots\/New fronds \u003c\/p\u003e","brand":"AquaHorizon","offers":[{"title":"Default Title","offer_id":46116236984516,"sku":"GDW","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/5971\/6548\/files\/GDW_img_main.png?v=1777981469","url":"https:\/\/shop.soil911.com\/es\/products\/giant-duck-weed-spirodela-polyrhiza","provider":"Tampa Home \u0026 Garden Store","version":"1.0","type":"link"}
