While other rockwool brands cut all sizes from the same batch of wool, Grodan is unique in that it manufactures different types of fiber. The purpose is to meet the plant's requirements at its different stages. Grodan has an enormous capacity to absorb nutrient solution while retaining enough oxygen for rapid growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then to panels, if desired. Seedlings or cuttings started in Grodan cubes can also be transplanted into more traditional pots and growing media. Grodan blocks: Grodan Delta blocks are the most uniform blocks available on the market. They feature improved grooves at the base to promote better drainage. They are available in a wide assortment of sizes and configurations to suit all types of plants. These growing blocks are used for direct sowing or for blocking on plants grown in Macro and Multiblock. AO 36\/40 plugs fit well into the holes provided by the blocks. The blocks can then be placed on a panel to provide a larger growing volume. Hugo is the largest of the growing blocks. It offers enough growing volume to support a larger plant, so it does not need to be placed on a panel.

Various grades available: Perlite #2 (1\/16\" - 5\/8\" granules), Perlite #3 (1\/8\" - 5\/8\" granules), Perlite #4 (1\/3\" - 3\/4\" granules), and Perlite #8 (3\/4\"-1 1\/3\" granules).\u003c\/p\u003e\n\u003cul style=\"box-sizing: border-box; margin: 0px 0px 1rem 15px; outline: none; padding-right: 0px; padding-left: 0px; list-style-position: initial; list-style-image: initial; color: rgb(85, 85, 85); font-family: opensans, Arial; font-size: 16px;\"\u003e\n\n\t\u003cli style=\"box-sizing: border-box; margin: 0px; outline: none; padding: 0px;\"\u003eIncreased aeration and drainage\u003c\/li\u003e\n\n\t\u003cli style=\"box-sizing: border-box; margin: 0px; outline: none; padding: 0px;\"\u003eCompletely sterile\u003c\/li\u003e\n\n\t\u003cli style=\"box-sizing: border-box; margin: 0px; outline: none; padding: 0px;\"\u003epH neutral at around 7.0\u003c\/li\u003e\n\n\t\u003cli style=\"box-sizing: border-box; margin: 0px; outline: none; padding: 0px;\"\u003eOdorless and lightweight\u003c\/li\u003e\n\n\t\u003cli style=\"box-sizing: border-box; margin: 0px; outline: none; padding: 0px;\"\u003eHelps to loosen heavy soils\u003c\/li\u003e\n\n\t\u003cli style=\"box-sizing: border-sizing; margin: 0px; outline: none; padding: 0px;\"\u003eDerived from a natural source\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp style=\"box-sizing: border-box; margin: 0px 0px 20px; outline: none; padding: 0px; color: rgb(99, 99, 99); font-family: opensans, Arial; font-size: 16px;\"\u003eNow with 15% more perlite in every bag!*\u003cbr style=\"box-sizing: border-box; margin: 0px; outline: none; padding: 0px;\"\u003e\n(*compared to Plant!t perlite)\u003c\/p\u003e\u003ch3\u003eTechnical Data\u003c\/h3\u003e\u003cul\u003e\n\n\u003cli\u003eVolume: 4 cu ft | Brand: GROW!T | Grade: #3 Super Coarse | Type: Expanded perlite for drainage and aeration\u003c\/li\u003e\n\n\u003cli\u003eSuper coarse particle size (approx. 0.25-0.5 in) maximizes drainage and prevents compaction in substrate mixes\u003c\/li\u003e\n\n\u003cli\u003eSterile, pH-neutral volcanic glass — no pathogens, no pH interference, and no degradation over time\u003c\/li\u003e\n\n\u003cli\u003eIdeal for amending substrate and coco mixes or as a standalone hydroponic substrate in drip and flood \u0026amp; drain systems\u003c\/li\u003e\n\n\u003cli\u003eCommercial 4 cu ft bag for mixing large batches of substrate or bulk hydroponic fills\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch3\u003eHow to use\u003c\/h3\u003e\u003cul\u003e\n\n\u003cli\u003eMix 20-50% perlite by volume into substrate or coco coir for improved drainage and aeration\u003c\/li\u003e\n\n\u003cli\u003eFor hydroponic use: rinse before use and fill pots for excellent root oxygenation\u003c\/li\u003e\n\n\u003cli\u003eDampen before mixing to reduce dust — wear a mask when working with dry perlite in enclosed spaces\u003c\/li\u003e\n\n\u003cli\u003eReusable between crops — rinse and sterilize with a 10% hydrogen peroxide solution between cycles\u003c\/li\u003e\n\n\u003cli\u003eStore in a dry location — perlite is inert and does not expire, but should be kept clean and dry\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"GROW!T","offers":[{"title":"Default Title","offer_id":48687984247039,"sku":"JSPERL34","price":66.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0072\/8324\/5092\/files\/6083_hf_20260721_132444_bc1aaf1c-9050-44fc-bb51-9c45ad894e9e.png?v=1785248018"},{"product_id":"roots-organics-formula-707-3-cu-ft","title":"Roots Organics Formula 707, 3 cu ft","description":"\u003cp\u003eFormula 707 is a ready-to-use substrate created for fast-growing plants with high nutritional demands.

The high perlite content and peat moss increase air porosity and reduce water retention, which favors the leaching of fertilizer salts during the growing cycle and decreases water-related problems that can cause root diseases, algae, and fungus gnats. This blend can be used directly from the bag or as part of a custom mix. When using Procision Advantage, water more frequently than you would with a general-purpose peat mix. HOW TO USE Use Procision Advantage Professional Grade Container Media as a primary growing medium or add it to your custom mixes. It contains bacteria that enhance nutrient uptake and mycorrhizae that increase root biomass and help containerized plants withstand stress.
