{"product_id":"hardwood-horticultural-charcoal","title":"Hardwood Horticultural Charcoal","description":"Use 5-7% charcoal in your soil mix to improve drainage and decrease soil funkiness. This charcoal is chunky with pieces between 0.5\"-1.25\". Great for aroid mixes and other chunky-soil-loving plants.\u003cbr\u003e\u003cbr\u003ePlease adjust your recipe if necessary - they often call for 10-20% charcoal, and if you start with a coco coir base this will raise the pH of your mix too much. Charcoal is basic (high pH; about 9.6), coco is slightly acidic and perfect for plants (between 6-6.8), and peat moss is too acidic for plants at about 3.5. A coco-based mix with 5-7% charcoal is a perfect ratio.","brand":"Oh Happy Plants!","offers":[{"title":"Generous Quart","offer_id":51878518259991,"sku":"CHARCOALQT","price":8.0,"currency_code":"USD","in_stock":true},{"title":"2 Gallon","offer_id":51878518292759,"sku":"CHARCOAL2GAL","price":24.0,"currency_code":"USD","in_stock":true},{"title":"10 Gallon Bulk Box","offer_id":51878518325527,"sku":"CHARCOAL10GAL","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/2482\/3063\/files\/salecharcoal.png?v=1770058115","url":"https:\/\/ohiotropics.shop\/products\/hardwood-horticultural-charcoal","provider":"Ohio Tropics Orchid \u0026 Houseplant Care","version":"1.0","type":"link"}
