{"title":"Drainage \u0026 Aeration","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eDrainage and aeration inputs are what keep a soil from packing down and holding too much water. They create air pockets through the mix so roots can breathe, excess water can drain away, and the soil life that depends on oxygen stays active. Get this right and you avoid the compaction, root rot, and stagnant, anaerobic conditions that hold plants back, especially in pots and containers where water has nowhere else to go.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis range covers three inputs for building that structure: washed perlite for lightweight, long-lasting air pockets, plus peanut shell and rice hulls for a more organic, plant-based way to open up the mix. Blend them through your base to hit the balance of water retention and airflow your plants and your climate call for.\u003c\/p\u003e","products":[{"product_id":"rice-hulls","title":"Rice Hulls","description":"\u003cp\u003eRice Hulls are a lightweight, natural soil conditioner that improves drainage, aeration, and soil structure while slowly contributing silica and carbon as they break down. With a slower decomposition rate than most organic mulch materials, rice hulls hold their structure in the soil for extended periods — providing lasting physical benefits long before they fully decompose.\u003c\/p\u003e\n\u003cp\u003eAs rice hulls are predominantly composed of silica and carbon, their value lies in what they do for soil structure rather than fertility. The silica content becomes plant-available as the hulls gradually break down, supporting stronger stems, thicker cell walls, and improved pest and disease resistance. The carbon feeds soil biology at a steady background rate without tying up nitrogen the way heavier carbon inputs can at high doses. They won't shift your NPK ratios, making them a safe structural addition to any mix.\u003c\/p\u003e","brand":"Soil Supply Co.","offers":[{"title":"5L","offer_id":49818587955440,"sku":"RICEHULLS-5L","price":8.0,"currency_code":"AUD","in_stock":true},{"title":"20L","offer_id":49818587988208,"sku":"RICEHULLS-20L","price":25.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/1262\/6416\/files\/ricehulls.png?v=1782530978"},{"product_id":"peanut-shell","title":"Peanut Shell","description":"\u003cp\u003ePeanut Shell is an ultra-lightweight, airy mulch material that excels at maintaining soil aeration while steadily contributing carbon and a modest nitrogen feed as it breaks down. Its naturally open, irregular structure resists compaction and matting far better than denser mulch materials, allowing air and water to move freely through the mulch layer and into the soil beneath.\u003c\/p\u003e\n\u003cp\u003eWhile primarily a carbon source, peanut shell carries a higher nitrogen content than most mulch materials, meaning it's less likely to cause nitrogen tie-up during decomposition — a common drawback with high-carbon, low-nitrogen mulches. The moderate breakdown rate sits between the fast-decomposing legume and sugar cane mulches and the slower rice hull and hemp stalk options, offering a balanced middle ground of lasting coverage and active soil feeding.\u003c\/p\u003e","brand":"Soil Supply Co.","offers":[{"title":"5L","offer_id":49818580287728,"sku":"PEANUTSHELL-5L","price":8.0,"currency_code":"AUD","in_stock":true},{"title":"20L","offer_id":49818580320496,"sku":"PEANUTSHELL-20L","price":25.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/1262\/6416\/files\/peanutshell.png?v=1782531184"},{"product_id":"washed-perlite","title":"Washed Perlite","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWashed Perlite is a pre-washed, dust-minimised additive used to improve drainage and aeration in growing media. Perlite starts life as a natural volcanic glass, but the white granules in the bag are manufactured, not mined: the raw ore is heated until the water trapped inside flashes to steam and puffs it up like popcorn, expanding it many times over into the lightweight material growers know. Unlike standard perlite straight from the bag, our washed perlite has had the fines removed — eliminating the clouds of irritating dust that make regular perlite unpleasant to work with, and reducing the amount of powdered material that can clog soil pores and impede drainage over time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAvailable in two grades — coarse and jumbo — so you can match the particle size to your specific application. Coarse grade is the all-rounder for general potting mixes and containers. Jumbo grade provides maximum airflow and drainage for large containers, raised beds, or mixes that need serious compaction resistance. Both grades are extremely lightweight, making them ideal for situations where keeping overall mix weight down is a priority — rooftop gardens, hanging baskets, or any container that needs to be moved.\u003c\/p\u003e","brand":"Soil Supply Co.","offers":[{"title":"5L \/ Coarse","offer_id":49818575044848,"sku":"PERLITE-COARSE-5L","price":11.0,"currency_code":"AUD","in_stock":true},{"title":"5L \/ Jumbo","offer_id":49818575077616,"sku":"PERLITE-JUMBO-5L","price":12.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/1262\/6416\/files\/coarseperlite.png?v=1783391219"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/1262\/6416\/collections\/ricehulls.png?v=1783323092","url":"https:\/\/soilsupply.co\/collections\/drainage-aeration.oembed","provider":"Soil Supply Co.","version":"1.0","type":"link"}
