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.

How do you transfer rockwool to soil?
Dip the stem of the cutting into rooting hormone. You can use either a powder or a gel. Plant the stem in the Rockwool cube, making sure the end doesn’t poke out of the bottom. Fill a growing tray until level with perlite, vermiculite or potting soil and tap the tray gently to settle the growing mix.
Can you bury rockwool in soil?
Dig a hole in the soil that is the same depth as the rockwool cube and twice the diameter, using your hand. 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.
When can I transplant rockwool?
Transplant! When your seedlings are about three inches tall and have roots protruding from the bottom of the rockwool cubes, it’s time to transplant. But about a week before you do, you should harden off your seedlings.
Is rockwool good for starting seeds?
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.
How long should clone roots be before transplant?
Roots should be at least two to four inches long before transferring to soil. You can absolutely wait until the roots are longer. I’ve kept cuttings in water for months!
Can rockwool cubes be reused?
Do: Reuse and Recycle Rockwool At the end of the plant life cycle, horticultural rockwool can be reused to grow different plants, or you can shred it to be composted and then reused in potting mixes or in garden beds.
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.
Is rockwool better than Coco?
” Rockwool is traditionally used as a hydroponic media for larger plants such as tomatoes as they do very well with the larger cubes for support. Coco coir holds the nutrients in the soil for the plant to absorb while also providing the support needed for heavier plants in the fruit production stage.
How do you grow tomatoes in rockwool?
To sow seeds, soak small rockwool cubes in water, and then simply put several tomato seeds in each cube. Place the cubes in a nursery tray with a humidity dome. You won’t need lighting until the seeds sprout, but keep them in a relatively warm spot. Keep the cubes moist during germination.
Can you use vermiculite in hydroponics?
Vermiculite. A 50/50 mix of vermiculite and perlite is a very popular medium for drip type hydroponic systems as well as ebb and flow systems. Vermiculite is inexpensive. The major drawback of vermiculite is that it retains too much water to be used by itself.
