best way to germinate seeds indoors

Line the bottom of the first plate with a few layers of wet tissue and drain any excess water from the plate.

Place the cannabis seed, root first, into the hole and cover with a small amount of growing medium – just enough to block light, not enough to obstruct the seedling when it emerges.

Step 1. The setup – How to germinate cannabis seeds

This article explains how to correctly germinate your cannabis seeds, covering everything from optimum temperatures, to potting your seedlings and transferring them outdoors (or inside under lights).

Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.

Seeds should be placed on top of the tissue, allowing each seed as much space as possible.

For seeds to germinate, most must be kept warm: about 65 to 75 degrees Fahrenheit. A favorite place to keep seeds warm in order to germinate is on top of the refrigerator. Or, you can purchase seed-warming mats to place under the seed trays. Once a seedling emerges, they can tolerate fluctuating temperatures (within reason). Whatever type of light you use, natural or artificial, make sure it produces enough heat to keep the plants in the 65- to 75-degree range.

It is quite economical to start seeds indoors, especially when the seedlings grow into robust plants. However, growing seeds indoors can be challenging. To significantly increase your chances of success, avoid these common seed-starting mistakes.

To be able to identify seedlings as they grow and to know when they will be ready for transplanting, you should label the seed containers as you are sowing. For every type of seed sown, use popsicle sticks or plastic plant markers and permanent ink pens to record the plant name and date sown. Insert the plant labels into the soil near the edge of the container or tray.

Keeping Seeds Too Cool

The amount of water you supply can make or break seedling growth. Watering is one of the most challenging aspects of seed starting. Because seedlings are so delicate, there is very little room for error when it comes to watering. You must keep the sterile seed-starting medium damp but not wet.

There is no benefit to a tough-love approach with seedlings when they are young. They will either instantly die or become weak and then fail to thrive. Even the most stalwart plants, when young, need a considerable amount of coddling and attention.

It is important to have pots and soil ready to go.

Sprinkle seeds in groups on the damp paper towel, close the lid, and make a note to yourself what type of seeds are where, especially when you have seeds that look identical, for example- broccoli, kale and cauliflower.

Plant them at a depth of 1-2 seeds size ( shallow depth for small seeds, deeper for bigger seeds) , and gently mist them daily for the first week.

Sounds familiar? Once you try the paper towel method to start seeds, you will rarely go back to the soil method. Here’s why.

For the first 1-2 weeks after planting them in pots, mist the seedlings or gently water them, and keep the soil moist. They are fragile and can fall over easily!

There is one extra step of planting the germinated seed in soil. So if you want to plant a whole field of flowers or vegetables, this method will not be practical.
