What makes a cannabis seed good for outdoor growing?

Outdoor cannabis seeds are bred to withstand natural challenges like pests, rain, and temperature swings. The best outdoor strains develop strong root systems, thick stems, and greater resistance to mold, making them perfect for open-air environments.

When is the best time to plant outdoor cannabis seeds?

The ideal time to plant outdoor cannabis seeds is after the last frost of spring, when temperatures consistently stay above 60°F (15°C). In most regions, this means planting between late April and early June for a full summer growth cycle.

Can autoflower seeds be grown outdoors successfully?

Absolutely. Autoflower seeds thrive outdoors and are a great choice if you want multiple harvests in one season. They don't rely on light cycles to flower, making them perfect for regions with shorter summers or unpredictable weather.
