cannabis seeds slow or no germination

Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

Climate considerations

Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.

Within a week or so you should see a seedling begin to grow from the soil.

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.

Use bottled water for germination. If you need to use tap water, fill a bucket with hot water and let it sit outside for a day. This allows the chlorine to evaporate so the water is safer to use for germinating.

To get your grow off to a great start, sourcing quality cannabis seeds is the best thing you can do. Not only will your germination rates be better, but your plants will also grow healthier with better yields at harvest time.

Some growers like to germinate their seeds in a glass of water. While this method technically is viable, there is also a risk that the seeds will drown if allowed to sit for too long. After all, seeds need a good supply of oxygen to grow.

11. TEMPERATURE TOO HIGH

Unless you are using cuttings, growing weed starts with germinating your seeds. If your seeds don’t sprout, for whatever reason, your grow will be over before it even has a chance to start. But If you know the reasons behind germination problems, your chances of getting your grow off to a great start will greatly increase!

Seeds don’t need light to germinate. In fact, too much light can decrease their likelihood of popping. You only need to worry about providing light once your seedlings actually emerge from the soil. But make sure to start with low light intensity before gradually increasing over time.

Do your due diligence and verify when local temperatures are high enough to set your plants outside. Usually, waiting a couple weeks for higher spring temperatures is worth it!

Tips

3.) Germination

You are about to water your seedlings for the first time, so prepare your water now.

If your growing medium takes longer than 3 days for the top inch to dry, it means the soil is staying wet too long, and plant roots aren’t getting enough oxygen. It also puts your plants at risk of getting fungus gnats . Try giving less water at a time until the plant is drinking more. It’s possible you may have a problem with drainage in your medium ( what is good soil? ) or there are no drainage holes so extra water can’t come out the bottom of the container. Always remove any runoff water instead of letting the plant sit in it.

If there’s no germination at all…

Try to maintain a schedule that lets you water your plants every few days without them looking droopy
