Rock Wool Seed Starter- 1''x1''x1'', 4 Sheets, Total 200 Cubes

There may be many growers who are unfamiliar with the role of rockwool starter plugs in gardening, especially for those who like traditional planting. Actually, the structure of the fibers in seed starter plugs contain beneficial water retention and air porosity properties that allow root systems to develop. Now, it's time for us to fully know hydroponic rockwool:

• 96% Porosity: Allows the nutrient solution to infiltrate all the tiny pores in the hydroponic seed starter plugs, ready for your plant to access, prepare the entire volume to be colonized by roots.
• Great Aeration Properties: The hydroponic starter plugs have a unique natural moisture gradient between the top and bottom sides, they can provide superb air circulation and oxygenation of the root system.
• 91% Water-Holding Ability: The cloning plugs have an excellent water retention property, which is very essential for the germination of your seeds.
• Perfect Drainage: The plant plugs will not waterlog your system. It has the ability to drain excess water, retaining just the right amount of water needed by your seeds to germinate.
• Perfect Combination Of Water and Air: This mix of air and water creates the paradoxical conditions many tricky-to-grow plants need in order to thrive- consistent access to an even level of moisture, yet simultaneously perfect drainage and continual air flow.
• Long-Lasting & Reusable: Being made of stone, rockwool blocks do not break down over time and has the potential to maintain its structure for repeated usage for a very long time.
• Rockwool plugs Does Not Lock Out Any Fertilizer: All the nutrients present in the cubes will be in the solution available to the plant or ready to drain out the bottom. What you put into your hydro system or nutrient reservoir is what you get.

When you make the plants sit in nutrients with unlimited oxygen being supplied, your plants willl attain crazy growth, which means bigger yields for you!

Hydroponics: The Future Of Farming And Gardening

Have home gardeners ever wondered that they could grow their beloved plants without soil? Actually no, before they heard about the term 'Hydroponics'. Hydroponics is not any machine, but rather it is a technique to grow plants without any soil, especially vegetables.

Rockwool starter cubes are ideal for working in hydroponic systems. Some of the major advantages of rockwool for hydroponics are listed below:

• Excellent for seed germination, clone plants, growing vegetative and fruiting crops.
• Rather than having to battle the soil to obtain water and nutrients to grow, hydroponic systems give the plants what they need right away.
• The plants grow comparatively fast because they get all the essential nutrients easily and in proper quantity.
• The crops have their own nutrients supply and do not need to compete for root space so, per square yield outputs are high, per unit of time when compared to normal gardening techniques.
• The application of seed starting plugs in hydroponic systems is an ultimate technique for the home gardeners which were seeking high yield in a small cultivating space.

Because important water and nutrients are delivered straight to the roots, the plants grown in hydroponic grow media grow 30-50% faster than those grown in soil.

Some people may wonder why it is necessary to choose rockwool clone cubes among so many soilless media? In fact, rock wool is a versatile growing media with lots of advantages over other options:

• Growers that use rockwool products have much more control over what goes into their plants’ root zones.
• They can control nutrient and moisture levels more easily than with other media. This is a plus for deliberate and conscientious growers.
• Rockwool rooting cubes will maintain whatever EC level is present in your solution. This also makes it easier to leach out nutrient excesses when discovered as rockwool will not hold on to nutrients. It does mean additive nutrients can take effect more rapidly when introduced to the system.

Rock wool stands out in the hydroponic substrate, plants seeded in it can achieve 20% higher germination rates & 30% higher crop yields & shorter planting period compared to other general soilless media.

Growers can steer their plants more easily towards vegetative or flowering or fruiting growth depending on nutrient values and how they are adjusted.

Rockwool seedling starter is a lightweight hydroponic growing substrate, so it is easy to handle and store.

• Easy to Transplant: Rockwool cloning cubes can be used for direct seeding, propagation by cuttings or transplanting. Plants can spend their entire lives in starter cubes or be transplanted from them into other growing media or containers.
• Independent Root System: Each plant can concentrate on growing the plant mass rather than spreading its roots for the nutrients. Hydroponic systems give water and nutrients straight to the roots, so they don’t need to worry about spreading. Less spreading, more space!
• Temperature Control: The special inorganic fiber structure makes clone plugs have unique and stable thermal insulation performance, which can reduce heat exchange caused by temperature difference, and the planting environment will maintain a constant temperature.

4 Top Tips For Growing Plants In Rockwool

The high growing performances can be achieved with rockwool, but there are still a few misconceptions as to how to use this substrate to maximum effect. The following guidelines contain some of the most common do’s and don’ts to help you make the most of your grow cubes for hydroponics.

• Wear Gloves & Cut It Instead of Tearing It: If you have had any issues handling fiberglass insulation, then you should assume the same issue will ensue during and after handling rockwool products. Individuals with sensitive skin should use gloves when handling it. If you need to separate rock wool blocks, you can use scissors to cut it to get rock wool blocks of uniform size.
• Pre-soak Your Starter Plugs: Unlike some other media, rock wool is not ready to use “right out of the bag”. pH levels that are too high (too low as well) will block the uptake of nutrients to your plants. Pre-moistening your cubes in distilled or deionized water for 24 hours will neutralize the pH, you should obtain a stable PH reading between 5.5 and 6.5 before use.
• Irrigate With Nutrient Solution Instead Of Water: If you irrigate with just water, the fertilizer concentration in the block will drop and may cause a slight shock to the plant. Rockwool has a tremendous capacity to retain water, so it is better to irrigate less often with a well-balanced nutrient mix than to water more frequently without the nutrients.
• Do Not Squeeze Them: A common myth is that excess water in rock wool should be removed by squeezing the plugs. Do not do this! Crushing the wool damages that structure and the air pockets that were initially present will never be restored. Always let your hydroponic plugs drain freely until there’s no more water running out of it.

To successfully grow in rockwool and to take advantage of all its benefits, growers will need to adapt to the distinctive needs of rockwool grow culture.
