How to Germinate Marijuana Seeds: 4 Methods Plus Expert Tips


What Do Marijuana Seeds Need to Germinate?

When germinating cannabis seeds, think springtime conditions. In the wild, your cannabis seeds  would germinate in the spring so they can be ready to take full advantage of longer summer days! If you follow the guidelines outlined below, you will see the best germination rates:

Moisture – Keep things moist but not soaking (you can soak hard seeds for up to 24-32 hours, but do not leave seeds soaking in water for longer than that). If a seed’s root breaks through the shell and the moisture around has dried up, your seedling will die. Plain and simple.

Seedlings are fragile at first. Once sprouted, the roots need to stay constantly moist to stay happy and healthy. It’s important to make sure the seeds have access to water the entire time during germination, no matter which cannabis germination method you end up using.

Peace and Tranquility – Seeds need to be left alone while you’re waiting for the taproot to show up. Be careful when checking seeds, and treat them gently when you have to move them. Avoid touching their white root if possible; the taproot is very fragile and easily snaps off!

Warmth and Humid – Keep things warm to get the best germination rates, but not too hot! Think springtime. Seeds can definitely germinate in cooler temps, but germination tends to take longer when it’s cool.  Some people will also place a heating pad (the kind you get from a garden store for seedlings) underneath seeds to help aid germination. I have also set them behind a TV or on top of fridge, as both generate heat.

Young marijuana seedlings do better with higher relative humidity in the air. They grow faster and healthier when they can absorb moisture from the air through their leaves while their roots are still developing. If your seedlings are uncovered or the air is dry, try using a spray mister to keep the little ones moist.

Plant Root Down – After your seed has sprouted and ready to plant,  with your finger, push a hole in grow medium 1/2″ to 1″ deep, point the white root downwards into the growing medium to prevent the seedling from having to reorient itself. cover loosely with grow medium.
