CBD is a cannabinoid that is known for having medical and anti-anxiety properties. Most photoperiod strains these days are high THC, low CBD, and it can be hard to find high-CBD photoperiod strains. Learn more about THC vs CBD.

Photoperiod strains usually take longer to harvest than autos. In general, photoperiod strains are ready to harvest 3-4+ months after being sprouted from seed, though the final time depends heavily on your grow style and which strain you choose. Even photoperiod plants flowered from seed tend to take longer than an auto-flowering plant to be ready to harvest, and the yields are much lower. Photoperiod plants do best when given some time in the vegetative stage before they start flowering, and aren’t as well suited to quick harvests.

When growing photoperiod cannabis plants outside, flowering naturally begins when the days get shorter. For outdoor growers, this means that plants must be planted in the spring, and they grower must choose strains that will finish in time before winter.

Note: The auto-flowering internal clock is why it’s recommended to never take clones from auto-flowering strains – clones will be on the same time clock as their mother. Learn more about why it’s not recommended to take clones from auto-flowering plants.

Not convinced? Well, this will absolutely blow your mind. You know how everyone knows all ruderalis is low in THC and basically hemp. Everyone is dead wrong. A recent attempted reintroduction of industrial hemp to Siberia turned out to be a disaster. The Siberian Times reported on October 9, 2013, “We planted seeds of various types, with and without fertilizers,” noted Nimazhap Badmayev, a scientist involved in the project. “Our climate is extremely continental, with low precipitation. So, the plant adapts itself to our dry climate by increasing the concentration of THC (tetrahydrocannabinol).” Hemp turning into cannabis in Siberia of all places. The scientist continued, “No matter how much of this nice foreign hemp you plant, our local conditions will force it out.”

Breeding and Reproduction

Don’t forget, germination is the starter’s gun for an auto and that bean is going to race toward harvest.

Vegetative Growth

The seedling phase lasts for about seven to 14 days post-germination. High, 70 percent relative humidity (RH) and daytime temps within the 68-77°F range are optimal conditions for auto seedlings. As is a standard 18/6, 20/4 and even the 24/0 light cycle that all photoperiod growers are familiar with. With as little as eight hours of daylight, an auto seedling can persevere where photoperiods would wither. Moreover, the hardy auto can endure less-than-perfect environmental conditions. Cooler temps as low as 50°F would stunt most photoperiod seedlings but the ganja grunts can endure.
