If your seeds get exposed to light or rapid changes in temperature, these conditions will trigger them to use up their nutrient stores before they ever see soil, meaning they won’t have the nutrients they need to germinate. High humidity, on the other hand, can trigger fungi to grow on your seeds.

Before germinating your old seeds, try soaking them in carbonated water enriched with fulvic acid, germination booster, hydrogen peroxide, or gibberellic acid. For best results, use room temperature water and soak your seeds for 12 hours in a dark place.

IDEAL CONDITIONS FOR CANNABIS SEEDS

Yes, cannabis seeds can be stored in the freezer. The lower the temperature, the slower they decline. However, it’s usually not necessary to freeze your seeds. Meet the conditions we outlined above, and you should be able to preserve your seeds for up to five years and still get a high germination rate.

In a last attempt to germinate your seeds, creating a small cut in the seed’s shell may help. However, this is no miracle cure, and you’ll need to be careful to avoid damaging the inside of your seed.

The ridge is the slightly elevated side of your seed. Like other parts of the shell, this ridge can become extra tough over time. Removing it gently with a sharp Stanley blade can help your seed sprout.

This is a simple and cheap solution to start cooling down your growing environment. Fans disrupt still, hot air and will effectively create a convection current that will help to cool things down. The wind generated by fans will also gently stress your plants into developing thicker and stronger stems.

There are thousands of cannabis strains available on the market, and each one has been selectively bred over time to display specific desirable traits. Some breeders have managed to create cultivars that are particularly resilient to high temperatures. You can significantly reduce the risk of heat stress by starting with one of these varieties. Here are three heat-resistant strains we recommend.

INSTALL AN EXHAUST SYSTEM

Below, we’ll cover indoor and outdoor methods to prevent and treat heat stress.

Some growers find success using supplements to treat the symptoms of heat stress. These may be effective, but will only work long-term if the environment is cooled down using the techniques mentioned above.

Seaweed or kelp extract can help increase plant resilience both indoors and outdoors. Use the formula according to the manufacturer’s instructions and give your plants some extra protection using these nutrient-rich substances.
