{"product_id":"fine-horticultural-charcoal","title":"FINE Horticultural Charcoal","description":"Use 5-7% charcoal in your soil mix to improve drainage and decrease soil funkiness. This charcoal is very fine textured - size varies but it's the size of a grain of rice: approximately 1\/2\" long x 1\/8\" wide x 1\/8\" tall. Great for fine-textured roots (begonias, succulents, etc). \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":51878515343639,"sku":"FINECHARQT","price":12.0,"currency_code":"USD","in_stock":true},{"title":"2 Gallon","offer_id":51878515376407,"sku":"FINECHAR2GAL","price":44.0,"currency_code":"USD","in_stock":true},{"title":"10 Gallon Bulk Box","offer_id":51878515409175,"sku":"FINECHAR10GAL","price":140.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0956\/2482\/3063\/files\/Charfinesquarter.jpg?v=1770058111","url":"https:\/\/ohiotropics.shop\/products\/fine-horticultural-charcoal","provider":"Ohio Tropics Orchid \u0026 Houseplant Care","version":"1.0","type":"link"}
