To Plant Seeds:
- Insert 2 seeds in the hole on the top of the rockwool cube.
- Pinch the hole closed.
- Place the cubes in a nursery tray and cover with a humidity dome to lock in moisture.
- Maintain at 70 – 80°.

Do seedlings in rockwool need nutrients?
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.
Why won’t 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 start seeds in a hydroponic system?
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.
When should I start feeding my hydroponic seedlings?
As for when to start using them, a good rule of thumb is to start using them when your plant begins to grow its first true leaves. The leaves that first sprout (after germination) on a seedling contain all the nutrients the seedling will need for the first few days of its life.
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.
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 put rockwool cubes in soil?
Rockwool cubes, 1 or 2 inches wide and 1 1/2 inch deep, are used for germinating seeds for seedlings that are then transplanted into soil or hydroponic gardens, reveals Simply Hydroponics. Cubes 3 and 4 inches wide are used as a primary growing medium for small plants.
Do I remove rockwool before planting?
Cut the rockwool cubes apart with scissors. Remove any rockwool from the outside of the cube that you can gently tug away. Place the cube into the prepared planting hole and pack the soil around the base of the seedling.
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.
When can I transplant seedlings?
The ideal time for transplanting your seedlings is about 3 weeks after they sprout or when you have 1-2 sets of true leaves. It’s better to get them in new containers before they start to show the signs of stress listed below.
Why do split seed do not germinate?
Split seeds don’t germinate because: Water or moisture is required for seed germination or dormant seeds are extremely dry. The seed has to absorb water in order to become active. The softened seed coat splits open as the seed grows too big for its encasement and germination has commenced.
