Here is some useful information to learn more about seed germination.
What quality are my seeds?
- Most dark seeds will germinate when given proper conditions. Generally, pale-green or white seeds will not germinate.
- On average you can anticipate about 75% of your seeds will germinate. Ordering seeds from a reputable breeder can increase these rates to 85%+.
Timeline for Seed Germination
- 36 to 96 hours - Water is absorbed, root tip pops through outer shell and is visible.
- 10 to 14 days - First roots and root hairs become visible.
- 14+ days - Seeds not rooted by day 14 will probably grow slowly if they germinate at all.
Once a seed has roots, its cell growth accelerates. Seedlings develop into full vegetative growth within 4 to 6 weeks of germination.
Planting Your Seed
Planting your seed directly into a coco pod will deter the shock of transferring a young already-sprouted seedling Because the seed starts in its final resting place, your seedling will immediately start adjusting to its environment.
When planting your seed in the coco pod:
- Make sure you plant it knuckle deep (0.25 - .75 inches) in the moistened coco pod.
- Cover the seed with a small piece of the coco pod. This can be torn off the side.
- The lights in your Grobo will keep things warm in order for your seed to sprout.
Importance of Moisture Timing
Seeds need oxygen from the air to germinate. Coco pods that are too wet will cut off oxygen, drowning the seed. Coco pods that are too dry won’t provide the moisture needed for proper germination. As soon as the seed germinates and roots develop, the coco pod must start drying out to prevent damping off.
