[Packing List] You will receive 1 soilless culture medium with 50 plugs in total, which is enough to support planting a large number of plants, and you will experience the pleasure of planting.
[High-quality material] Our rock wool plug is a very effective hydroponic product. It is made of high-quality basalt. After melting at high temperature, it forms fibers at high speed, and it is compressed into blocks by a proprietary process. It has soft and uniform texture, good water absorption and strong air permeability, which is conducive to root growth.
[Usage] The pH value of the new stone wool Square is relatively high, generally 7-8, so please dilute it with water until it reaches 5.5-6, or add appropriate acid, squeeze some lemon juice to reduce the pH value of the juice, and then use it. Please wear gloves when using.
[Easy to transplant] Growing cubes make seeds long enough to establish root system. Because they have high water absorption and retain a lot of oxygen, you can cut them into different sizes. The cubes wont corrode after immersion, so they are easy to transplant to net pots, soil.
