Germination is the first process a seed goes through in its life cycle. It is important to understand the process of germination, the conditions a seed needs to germinate, and how this affects your yCubes so you can optimize your germination at home!
5 Key Tips for Best Sprouting Results:
#1 : Don't expose your sprouts to plant food until true leaves emerge
Since the seed coat provides enough nourishment for the germination process, sprouts don’t need any plant food until the true leaves replace cotyledons (or first leaves)! Kelby will help guide you around day 10 to help you understand if it is time to add plant food based on the growth of your plants.
#2: Don’t use yCovers while sprouts are still germinating
yCovers lock in moisture and inhibit germination. It is important that you wait until you see true leaves and have thinned your sprouts before adding a yCover.
#3: Keep the pre-set watering schedule and ensure 14-16 hours of light in boost mode daily
Your Gardyn is already set up to meet the water and light needs of your seeds.
Water: The rockwool growing medium in the yCubes is very absorbent and doesn't require as much water as soil to germinate seeds. Keep your watering schedule on the pre-set mode to ensure your seeds get just enough water, not too much or too little. While water is vital to start the germination process, too much of it can cause germination issues so it is important NOT to overwater your yCubes.
Light: The light helps create the warm conditions needed for germination, and will help direct the embryo as it stretches for the light. Ensure 14-16 hours of light in boost mode daily. A smiley in your light schedule screen will let you know your plants are getting enough light.
#4: Periodically check the temperature and humidity level of the room in which your Gardyn is located in the Gardyn app.
The optimal conditions for germination is when room temperatures are above 70F and humidity is between 65%-75%.
#5: Cover using a lid with holes or a vent if germinating seeds in the Gardyn Nursery or a tray.
A vented lid helps control the temperature and humidity for your seeds, producing the ideal environment for sprouting.
Germination: From Seed to Seedling
Germination is a process in which an organism grows from a seed or spore. In this case, this is applied to the sprouting of a seedling from a seed.
A seed contains a new plant, or an embryo, with the outer cover protecting and nourishing the embryo. This seed remains dormant until it is given the growing conditions it needs to thrive. All seeds require to germinate is the right amount of water, light, humidity, and warm temperatures.
As the seed absorbs water, it begins to expand or swell, eventually splitting open the seed coat. Once the seed coat is cracked, the root will begin to grow downward to enable the plant to take up water and nutrients. The embryo will then shoot upward as it reaches for the light, and will eventually show the cotyledons, or first leaves.
How do I recognize a seedling from a sprout?
A sprout has just its first leaves, while a seedling has developed true leaves.
Screen your plants and be on the lookout for true leaves. Some plants may take longer to sprout than others. For instance, lettuce starts sprouting between 5-10 days whereas peppers usually sprout between 1-2 weeks. True leaf development follows sprouting.
You can scroll through the Plant Book in the Gardyn App for variety-specific information.
What are the next steps once I identify seedlings?
The development of true leaves also means that the yCube is ready for its first taste of plant food!
Be sure to keep the yCubes that do not have developed true leaves in a tray or Gardyn Nursery because they are not ready for plant food! Adding plant food too early can actually hurt your sprouts.
