When they have finished soaking, remove them from the water and carefully add them to the hydroponics system and allow the system to run without any plants until the pH of the system stays between 5.5 and 6.0 — this means the cubes are stable and can be used.

When should I transfer hydroponics?
Plants should be transplanted when they have developed 2–3 sets of true leaves. Transplant is the stage that comes after propagation; it’s when you move your young seedlings into your grow-out system.
Why wont my seeds germinate in rockwool?
If soil conditions are too wet, an anaerobic condition persists, and seeds may not be able to germinate. Do not leave your rockwool totally submerged in water! If your soil (or in our case rockwool) is too cold or too hot, your seeds may not sprout.
Can you plant rockwool directly into soil?
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.
Is rockwool bad for your lungs?
Not only is rockwool unfriendly to the environment – it’s also potentially harmful to your health. New blocks can contain a lot of dust and loose fibers that can get in your eyes, mouth, skin and lungs. If you’re using rockwool, you should be using a mask, goggles and gloves when you work with it to protect yourself.
Can you start seeds in rockwool?
Rockwool cubes are popular for germinating seeds in because of their excellent moisture retention — they are great at helping to keep seeds or seedlings from drying out but don’t let them sit in a waterlogged environment. Moisture is the critical factor in seed germination.
How often should you water seedlings in rockwool?
Rockwool holds about 80% water and 20% air when oversaturated and needs to dry out (similiar to a soil-based medium) before it is watered again. In an ideal environment, Hugo Rockwool blocks generally need watering once a day in the Vegetative Growth Stage and twice a Day in the Bloom Stage.
Can you put seeds in hydroponics?
Here are just a few reasons why you want to start seeds in a hydroponic system as opposed to soil: Much cleaner than starting seeds in soil. Seedlings grow faster after germination. Easy to transplant into a larger hydroponic system.
Can you use seedlings in hydroponics?
Create some space in the growing medium in your “grown-up” hydroponic system. Place the entire cube with the seedling inside this space. Gently cover the cube with more growing medium. Water the seedling from the top with a nutrient mix in the first few days.
Do I need to soak rockwool?
Soaking the rockwool as a way of preparation which can correct the pH level of the substrate. Even if the rockwool has an adjusted pH prior to preparation by manufacturers, soaking rockwool can help ensure that the medium drains sufficiently as it usually ships completely dry (7).
How long does rockwool last?
ROCKWOOL insulation should last the lifetime of your building if installed in a properly designed system according to spec. ROCKWOOL products will not decay since they are inorganic, so they will retain their properties assuming no physical damage occurs. 23) Is there any off-gassing with ROCKWOOL products?
Do you add nutrients to rockwool?
Unlike soil, rockwool does not come with any nutrients in it. That means you’ll need to add a nutrient solution to the water you irrigate with. Fortunately, rockwool holds nutrients well, keeping them close to the roots.
