Who ever said that strains of marijuana can only live for one growing season? Your plants do not have to die when the harvest arrives: there is a method that allows them to defy the Grim Reaper and to rise again - for a long time. It is called “revegetation” and it is the biological key to growing genuine trees of grass that keep on growing, even after multiple harvests. The limits on weed's longevity are unknown, but some have said that the key to its immortality has already been found.

Cannabis does not have a genetic indicator determining its time of death. Its existence depends upon the authentic breath sustaining its life: light. It is this luminescent energy that, along with other environmental factors, determines your plants' longevity. Your plants can live longer if, for example, you place them indoors after the harvest. And this is why they can grow for years in tropical areas whose photoperiod is stable year round (12/12).

Revegetation, or life after the harvest

You can add years to your plants' lives if you stoke their photosynthesis, the most important factor for their survival and longevity. This process will allow them to revegetate after the harvest if you use the correct techniques. You can pull it off if you transfer them to indoor growing and increase their photoperiods. Replicating the same thing outside is difficult, as in our part of the planet conditions do not allow them to survive the winter.

Light can function as an authentic elixir of youth for our plants.

For your plants, to revegetate is to return to life. And to make this an efficient process you will, in addition, have to change their substrate, prune their roots, and use growth fertilizer. With the arrival of the summer you can take them outside; what before were plants will now be almost trees. And they can live for 5 years or more (if the process is repeated), although their effects will be more and more narcotic.

How to concoct the elixir of life for your favourite plants

Would you like to keep that plant you've fallen most in love with? And even see it grow, year after year? If your answer is “yes,” you'll have to save as many leaves as possible when you cut the buds, and subject it to a double transformation: a new substrate and a change of roots. Then you'll need to subject it to an 18/6 photoperiod, which in approximately 10 days will bring your baby back to life. New roots? Aside from the inevitable renovation of the substrate to eliminate metallic salts and work with the richest possible soil, you will have to begin by healing the radicular system. To do this it is necessary to remove the rootball and cut three fourths of it, all in order for new roots to develop, which will grow with greater force and absorb more nutrients. In just a short time the plant will begin to grow quickly once again.

The secret of cannabis longevity can be found in tropical areas

Lights are not the only thing that can “resuscitate” a plant and bring it back it to life. Its buds also can be reborn, in a natural way, in those parts of the world where the photoperiod is always 12/12 and temperatures are very stable. This is, above all, the case in the tropics, home to Sativas for thousands of years, where one can find genuine cannabis trees that do not die because they alternate between flowering and vegetation phases.

In the equatorial zones there have been cases of very old and giant wild Sativas.It may be that the secret to the longevity of these trees of weed lies in the blessings of their tropical surroundings, which allow for spectacular growth of the vegetation, not comparable to that found in any other ecosystem. Their very stable range of temperatures (usually oscillating between 24º-30º), their abundant rains, the fertility of their soils and the existence of a continuous photoperiod, are without a doubt the best natural conditions allowing marijuana plants to revegetate all by themselves.

Perpetual pot! Where? On the paradisiacal Reunion Island

The longest-living genetic ever documented is to be found on Reunion Island, an idyllic African isle that “belongs” to the French state. There grows, amidst coral reefs and majestic volcanoes, a local island strain that can yield two and even three harvests in a row. This is Reunion's so-called “perpetual pot,” which, with its long branches and thin leaves, grows like creeper in the jungle terrain of this little isle near Mauritania.

Hot and humid climates like that on Reunion Island are like superfood for grass.

Villagers sow them hidden in rough and green volcanic lands that lead to the heart of the island's volcanoes, so that the strict French authorities cannot find them. There, they develop very long internodes to stretch towards the capricious light filtering through the thick jungle vegetation. Two characteristics (the equatorial climate and the difficulty of accessing light) are shared by other large and long-living marijuana plants that have been found around the globe.

Buds forever: immortal grass is here

The dream of a marijuana plant that yields shining buds for years has come true. Immortal weed has arrived. “We have found the fountain of youth for marijuana,” proclaims the management at BC Seeds, a Canadian bank that may have found the genetic switch to prolong the life of marijuana into a very, very distant future. The biggest problem is that it is a transgenic strain, and adverse effects are feared.

The Canadian bank has already announced that the seeds for this immortal ganja will go on sale this February. But this is no trial run: they have a phenotype of this strain that has already turned 10 years old and stands over nine meters tall ... because they won´t let it grow any higher! And it produces annual harvests, like clockwork. The only concern they have when it comes to releasing this “eternal” marijuana onto the market is the consumer's reaction: would you plant it?
