Rockwool Cubes 1 inch, Rock Wool Planting Cubes, Rock Wool for Hydroponic Growing, Perfect for Rooting, Cuttings, Cloning Plants, Seed Germination (4 Sheets, 200 Cubes Total)

[96% POROSITY & 91% WATER-HOLDING ABILITY]- The density inside the rockwool gives it excellent moisture-retention and aeration properties. The unique moisture gradient from top to the base gives your plant access to the nutrient solution and oxygen. In addition, rockwool cubes for hydroponics has the ability to drain excess water, retaining just the right amount of water needed by your seeds to germinate. These abilities make the grow cubes ideal for delicate new growth
[GREAT FOR HYDROPONICS]- The rockwool cubes is well-suited to hold moisture, and it will not break down through your grow cycle. It will remain strong and continue to efficiently retain water. This makes it ideal to use with hydroponic systems. The rockwool grow cubes can be used for starting seeds, growing vegetative and fruiting crops, both short and long-term. What’s more, the plants grown in hydroponic media grow 30-50% faster than those grown in soil
[HIGHER GERMINATION RATES & CROP YIELDS]- In a study comparing rock wool for plant to two other conventional hydroponic seed starter, rock wool seed starter came out on top. Plants seeded in the rock wool produced 70% germination rates as compared to the other tow hydroponic medium that each averages a 50% germination rate. Additionally, crop yields have been shown to be 30% higher in agricultural rock wool in shorter planting period
[TEMPERATURE CONTROL]- The special inorganic fiber structure makes rockwool seed starter 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. Temperature is easy to control with agriculture rock wool in indoor hydroponics, and making a microclimate is highly beneficial, especially during winter when the temperature drops outside
[QUICK & EASY TRANSPLANT]- The hydroponics rockwool cubes can be used for direct seeding, propagation by cuttings or transplanting. Plants can spend their entire lives in rock wool cubes or be transplanted from them into other hydroponic grow medium or containers. The plants need not be removed from the seed starter cubes, but cubes and all can be transplanted into their new home. This is far less disruptive for the plant and allows it to acclimate to its new home more quickly
[PREPARATIONS BEFORE STARTING]- Before starting or transplanting any plants into your grow plugs, the initial wetting of hydroponic rockwool cubes is critical, ideally it should be immersed in a nutrient solution adjusted to pH 5.5-6.5, the immersion time is 24 hours. Doing this allows the nutrient solution to infiltrate all the tiny pores in the grow medium, ready for your plant to access, prepare the entire volume to be colonized by roots
