Germinating Seeds; A fundamental breakdown.

There are two things to primarily consider when germinating seeds,


This is the way seeds know when it’s time to “rise and shine.” If you think about it Momma plant makes her seeds in the fall. The seeds hit the ground in the winter, where they wait till two things happen. It gets hot and….



“April showers bring May flowers” could not be any truer. Once the seeds sense this in tandem with the rise in temp *boom* taproot.

One of the most common beginner mistakes is over/under watering. If the media is constantly soaked then the new roots will have a hard time getting oxygen. Ideally you will keep the media moist and not wet.


For example In the photo above you can see the media isn’t touching the water. The water is in the bottom of the tray and when it evaportates (with the heat mat) it will increase the humidity inside the dome ensuring moist media.

#GrowFam Protip: Soaking with H202 

Hydrogen peroxide (H2O2) is quite popular in horticulture. It has an extra oxygen atom than water (H2O). When its molecule breaks down, this extra oxygen separates from the water, acting as a supplement to plants. It also helps in germinating seeds successfully by making them absorb more oxygen.

Soak your seeds in a 3% hydrogen peroxide for 30 minutes. Rinse the seeds several times with water before planting and plant them as usual. Doing this breaks down the hard outer covering of the seeds and kills any pathogen present on them. This allows the seeds to absorb more oxygen, helping them sprout efficiently.
