Magic rock wool cubes hydroponic 1 1/2'' agricultural rock wool growing plants in rock wool medium
Rockwool, a lightweight hydroponic substrate is made from spinning molten basaltic rock into fine fibers which are then formed into a range of cubes, blocks, growing slabs and granular products.
Because rockwool and other stone or mineral wools used in horticulture originate from rock, they are considered by many to be a natural product.
Rockwool is a widely utilized substrate in commercial horticulture for the production of crops as diverse as tomatoes, melons, cucumbers, peppers, strawberries, herbs and cut flowers; however it can also easily be used by smaller hydroponic growers wanting to take advantage of improved root zone technology.
They are most commonly used for starting lettuce and other leaf crops, tomotos and cucumber seedings,and flowers.
Propagation blocks are used for transferring seedlings started in the propagation cubes, when it is desired to hold them prior to putting them onto the slabs.
Slabs are the premium product for vegetable cropping. They are available wrapped in UV resistant polyethylene sleeves for ease of use. The special structure provides a uniform environment allowing plant roots to rapidly explore all the available growing volume for a quick start.

Benefits for using rockwool for growing:
1. It has a large water retention capacity, and also holds sufficient air. It holds a lot of water which gives you an advantage against power or equipment failures. And it also holds 18 - 25% air which gives the root system ample oxygen so long as the media is not completely submersed. 2. It is available in multiple sizes and shapes for various hydroponic applications. Everything from 1" cubes to huge slabs. 3. Rockwool is also durable, it doesn't readily fall apart or break down.
