Once it germinates though, how often you should water marijuana seedlings varies according to the temperature of where the marijuana seeds are growing, but as a rule of thumb, you should water the marijuana plant once the soil is dry. An easy way to tell is if you try and lift the edge of the pot with one finger; if it feels “light” then it’s time to water, if not then leave it a few more days to evaporate and check back often to water. Usually, when you follow this technique, it helps with the formation of trichomes on your marijuana plants during the flowering phase which is equal to dank-er flowers.
After the hassle of choosing a seed and getting it to sprout then grow, another of the big questions is how often should you water marijuana seeds until they germinate. You should not water marijuana seeds once you place them to germinate in a warm moist place. If you give your marijuana seeds water very often you will drown the seedling and it won’t be able to crack out of its seed.

Now that the Marijuana seed has germinated, how often should you water Marijuana seeds?
When you’re growing cannabis, you want to keep your plants strong and healthy through every stage of the growing process — and that includes the seedling stage.
If you try to grow your seedling in a container that’s too large, the root system won’t be able to absorb all the water in the soil. If you start growing your seedling in a container that’s too small, the roots won’t have space to extend and will start to wrap around themselves, which will also impact their ability to absorb water.
Be mindful of how much you water your cannabis seedlings
Growing your seedlings indoors with artificial light gives you more control over the process, making it easier to ensure your plants are getting enough light each day. If you’re growing with artificial lights (compact fluorescent lights that emit cooler, blue spectrum light are especially effective), aim to give your plants 18 hours on and six hours off each day.
