However, the reality is that sometimes you need to use grow media for a hydroponics system too. The reason is, it is needed to anchor the roots so that the plant can be supported in place. When you are growing outdoors traditionally in pots, garden soil is the most common choice. For hydroponic systems, you need a specific growing medium.  \u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"eop\"\u003e\u003cspan\u003e  \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 style=\"text-align: justify;\"\u003e\n\u003cspan class=\"normaltextrun\"\u003eWhat is a hydroponic grow medium?\u003c\/span\u003e\u003cspan class=\"eop\"\u003e  \u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cp class=\"paragraph\" style=\"text-align: justify;\"\u003e\u003cspan class=\"normaltextrun\"\u003e\u003cspan\u003eThe term ‘hydroponic grow medium’ refers to an inert material that is used to anchor your hydroponic plants in their place.

Stone wool consists of 5% solid material in the form of stone fibres. The remaining 95% is made up of pores.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is stone wool made?\u003c\/strong\u003e\u003cbr\u003e A: The basic materials for our stone wool are basalt and limestone. These are melted to form lava in an oven with a temperature of 1,500C. The lava is then poured over a number of fast-rotating discs. Thanks to the centrifugal force, the drops fly off the discs and lengthen to form fibres. The process can be compared with candy floss being made at a fair. The fibres are then compressed to form a sturdy mass, from which the slabs and blocks are then cut.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is stone wool suited for growing vegetables?\u003c\/strong\u003e\u003cbr\u003e A: Our stone wool growing media are designed for Precision Growing in a greenhouse. Precision Growing focuses on 'root zone management', or in other words, steering of the root environment. Everything that happens in the stone wool substrate has an impact on the functioning of the root environment and therefore the development of the plant. So, we continually investigate how our products, tools and user advice can respond perfectly to changing circumstances, so that the plant is given the very best care, without wasting resources.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Grodan","offers":[{"title":"Default Title","offer_id":43985902108906,"sku":"RWP31384","price":259.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2561\/3802\/products\/16715__71040.1657659135.1280.1280.jpg?v=1680142068"},{"product_id":"hydroponics-hydroponic-grow-media-pro-mix-bx-growing-medium-with-mycorrhizae-3-8-cu-ft","title":"PRO-MIX BX Growing Medium with Mycorrhizae, 3.8 cu ft - Pallet of 30","description":"Pro Mix BX Mycorrhizae 3.8cf\u003cp\u003e\u003cstrong\u003ePRO-MIX® BX  MYCORRHIZAE\u003c\/strong\u003e\u003cstrong\u003e™\u003c\/strong\u003e is a general purpose peat-based growing medium containing, a beneficial mycorrhizal inoculum (Glomus intraradices).

Stone wool consists of 5% solid material in the form of stone fibres. The remaining 95% is made up of pores.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is stone wool made?\u003c\/strong\u003e\u003cbr\u003e A: The basic materials for our stone wool are basalt and limestone. These are melted to form lava in an oven with a temperature of 1,500°C. The lava is then poured over a number of fast-rotating discs. Thanks to the centrifugal force, the drops fly off the discs and lengthen to form fibres. The process can be compared with candy floss being made at a fair. The fibres are then compressed to form a sturdy mass, from which the slabs and blocks are then cut.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is stone wool suited for growing vegetables?\u003c\/strong\u003e\u003cbr\u003e A: Our stone wool growing media are designed for Precision Growing in a greenhouse. Precision Growing focuses on ‘root zone management’, or in other words, steering of the root environment. Everything that happens in the stone wool substrate has an impact on the functioning of the root environment and therefore the development of the plant. So, we continually investigate how our products, tools and user advice can respond perfectly to changing circumstances, so that the plant is given the very best care, without wasting resources.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Grodan","offers":[{"title":"Default Title","offer_id":43985936613610,"sku":"RW241025","price":189.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2561\/3802\/products\/21317__45861.1657659142.1280.1280.jpg?v=1680143297"},{"product_id":"hydroponics-hydroponic-grow-media-grodan-improved-gr10-white-foil-4-x-4-x-4-1-584-blocks-loose-on-pallet","title":"Grodan Improved GR10 (White Foil) 4\" x 4\" x 4\", 1,584 Blocks Loose on Pallet","description":"Grodan GR10 Improved 4\" x 4\" x 4\", loose pallet, 1584 blocks\u003cp\u003e\u003cstrong\u003eGrodan Improved GR10 (White Foil) 4\" x 4\" x 4\" (1584 blocks  Loose on Pallet)\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eGrodan Improved\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eGrodan partnered with the Wageningen University and Research facility in The Netherlands and top growers throughout North America to identify the optimal stone wool substrate and irrigation strategies for specialty crops.

Stone wool consists of 5% solid material in the form of stone fibres. The remaining 95% is made up of pores.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eQ: How is stone wool made?\u003c\/strong\u003e\u003cbr\u003eA: The basic materials for our stone wool are basalt and limestone. These are melted to form lava in an oven with a temperature of 1,500°C. The lava is then poured over a number of fast-rotating discs. Thanks to the centrifugal force, the drops fly off the discs and lengthen to form fibres. The process can be compared with candy floss being made at a fair. The fibres are then compressed to form a sturdy mass, from which the slabs and blocks are then cut.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eQ: Why is stone wool suited for growing vegetables?\u003c\/strong\u003e\u003cbr\u003eA: Our stone wool growing media are designed for Precision Growing in a greenhouse. Precision Growing focuses on ‘root zone management', or in other words, steering of the root environment. Everything that happens in the stone wool substrate has an impact on the functioning of the root environment and therefore the development of the plant. So, we continually investigate how our products, tools and user advice can respond perfectly to changing circumstances, so that the plant is given the very best care, without wasting resources.\u003c\/p\u003e \u003c\/div\u003e","brand":"Grodan","offers":[{"title":"Default Title","offer_id":43985948311786,"sku":"RWDM5.6","price":40.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2561\/3802\/products\/713060__23840.1669572194.1280.1280.jpg?v=1680143756"},{"product_id":"hydroponics-hydroponic-fittings-tubing-floraflex-floracaps-6-x-6-2-0","title":"FloraFlex FloraCap 2.0, 6 Inch","description":"\u003ch2\u003e\u003cstrong\u003eFloraCap\u003c\/strong\u003e\u003c\/h2\u003e \u003cp\u003eThe FloraFlex FloraCap is a patent pending revolutionary tool for top feeding that also helps eliminate algae.

Place the FloraCap on top of your rockwool cubes, maximizing your space in the vegetative cycle. Fill the cap with water and nutrients by hand or automate with FloraClips. Each cap features flower designed louvers that deliver water, nutrients, and air to the medium while blocking light. The FloraCap strategically covers the top of the media allowing the root zones to dry at a more consistent rate and delivering the necessary oxygen your plants need to thrive.
