✅ 👍 HIGH QUALITY 100% brand new Color: Yellow size 1 inch x 1 inch x 1 inch 200 pcs Rockwool is a mainstay growing media for commercial hydroponics growers, primarily those who implement drip irrigation systems. Originally used as insulation and also known as mineral wool or stone wool, rockwool was developed in Denmark back in the 1970’s for gardening. It retains moisture well, it retains oxygen well, it never impedes root growth, it is chemically inert, and it comes in a variety of sizes and shapes. These benefits contribute to its popularity amongst growers, accommodating almost any plant they are growing Preparation: Rockwool has a naturally high pH of 7 to 8. Prepare a solution of slightly acidic water (pH 5.5 to 6.5) by adding several drops of lemon juice using pH test strips to attain the correct acidity. Soak the rockwool cubes in this solution for about an hour. Sowing Seed: Place two or three seeds in the hole at the top of the rockwool growing medium. Water using a hydroponic nutrient solution. When the plants are 2 to 3 inches (5 to 7.6 cm.) tall, they can be transplanted into soil or placed in a hydroponic garden.
