Regeneration - when the end is not the end.

Cannabis is considered an annual plant;

that is, the plant completes its life cycle in one growing season.

The seeds germinated in the spring and grow through the long days of summer,

until the shorter days of autumn induce the plant to flower and reproduce.

The seeds fall from the plant in late autumn and with the warmth of spring, they germinate in the soil.

When this happens the cycle is finished, and with the frosts and cold of winter the plant dies.

If, however, the weather is mild, the plant can survive winters that have no heavy freezes.

Outdoors, during the winter, the plants will grow slowly, but has soon as spring comes along,

the weather warms and the light is more intense, the plants respond with rapid new vegetative growth.

In such places as Hawaii, Jamaica or Thailand it is possible to have perennial weed plants.

Indoors of course, it is a different story as we are not as dependant on the seasons.

Indoors it is much easier to trick a plant into think it has survived the winter and it is spring again.

It is a shame to cut down a plant when it has an extensive trunk and root system;

Once the plants revert to vegetative growth,

they come back very quickly as they already have a well formed main stem and root system:

To Regenerate a Plant.

To prepare a plant for regeneration take the bulk of your crop byt leaves some lower branches with green leaves and some small buds; (See above.)

It is from the buds that the new growth will come from.(see below)

The plants revert much quicker when they are given 24 hours of light;

The light does not need to be intense at first, as the idea is to give the plant a long day so that it will revert from flowering back to veg growth.

Then give her a feed of nutrient which is high in nitrogen and micro elements.

After the first watering with a high Nitrogen fertilizer,

let the plant dry out so that the roots have plenty of oxygen so that they can absorb nutrients.

Moreover, as the plant has very little branches and leaves to transpire water, its water requirements are low.

Watch for magnesium and micro element deficiencies.

Once the plant has soon signs of new vegetative growth then turn the lights down to 18 hours a day of intense light.

You will see the new growth comes out of the buds(see below)

as the above plant shows more vegative growth, I shall post new photos to show the whole process, as the plant returns to rapid veg growth..

Happy regenerating,

great post john.

im interested to watch and see if your techniques and ways will make it re vegg quiker than average.

when ever i have re vegged or had a plant re vegg on me without me wanting it to it took a minimum of 6 weeks before it stopped re vegg. i have had them re vegg up to 2.5 to 3 months before though.

hi jay,

the difference between 20 and 24 hours would not be much.

Some plants take longer than others to switch back to veg

Did you fertilize well with a high nitrogen fert, and then let it dry right out?

The roots need lots of air to absorb micro nutrients.

I have done another post,

happy regenerating,

john

hi bigbuds,

Congratulations on winning bud of the month. it was well earned as your bud was excellent.

see below my friend,

happy growing,

I have no experience with autos;

but I think it could be a problem because of their short life cycle;

Light and heat, especially warmth, may be a trigger for them.

I do not know, but if you want to attempt regenerating an auto, I will help as much as I can if you post regularly.

I would be very interested in helping you do this, as it is new territory - not many people, if any, have done it.

happy growing,

john

Hey there Guru ,,

We have discussed the regeneration of "suicide bud" before in the shout !

It was a way back though !

I prefer do my auto's in the glasshouse as it cuts out the cost of a 20 hour light cycle ,

But when it comes to clearing up I'm kinda lazy in there ,

On that note I had stumps tick over for a long while after harvest ,

Some strains will tick over longer than others,,

I feel the more genticaly diverse the autos get the more chance we have of regenerating them,

But hey !

There is only one way to find out for sure ;)

You would know more than I do about autos Jay;

perhaps though it is possible, not with all autos but say with some, depending on the cross and how the percentage of genes from the rudalartis .

happy growing,

hi syn,

I think you are right in what you say - if the auto has minimum genes from the Siberia(I can not spell ruderalis), then I think it may be possible, as it is that side of the cross that would prevent the plant coming back and reverting.

I can only grow a limited number of plants and I like to grow them big, so I have never grown an auto,

but it would be cutting edge to see one regenerated.

have you ever tried cloning one?

happy growing,

john

hi jay,

I thought that may be the case; it may be a good test to see if the plant would regenerate;

if it clones, one may have a chance;

it it does not, then it probably will not regenerate either.

The autos are a very interesting strain;

if a breeder could isolate the genes responsible for the light independent flowering, and bred a strain that had only those genes except for genes from a normal plant, then it would be possible.

But to isolate the genes may not be possible as sometimes genes are passed on in groups.

It would take at least 4 to 6 generations, with access to a a sophisticated biotech lab, so i would not hold my breath waiting for it.

Things are, however, changing all the time, and what now is not possible may be possible in the future.

Please let me know how your experiments with your autos goes.

good luck,

happy growing,

john

Hey there folks,,

Jay

If the white russian has the genetics i think it does

(ruderallis x whitewidow x ak47)

That's similar genetics to the autos I've had run over in the past ,,

I always put it down to the ak47 gene ,,

The less geneticaly diverse and they seem to hold on to there suicidal tendencies !

It will be interesting to see your results

PeaceOut

I have never grown an auto:

here are the reasons why( besides having limited space and number of plants):

They do have a place for those who want a quick turnaround

BUT

In order to flower regardless of the light cycle they have to have a large percentage of ruderalis genes.

Ruderlatis is one of the 3 land races of cannibas:

it is a hemp plant(low THC) that has its origins in Siberia, but it does grow through out Eastern Europe as a weed strain.

It is a short plant that flowers quickly, as the Summer is very short.

This hemp strain was first sold as a cross with an indica by Sensi seeds years ago.

I do not grow these strains because they are low THC and are small low yielding plants.

I think Jay is dead right about regenerating these autos, as they must have at least 50% ruderlatis genes to be an auto.

most of the autos are F1 crosses; they have to be;

The ruderlatis land race has adopted to a very short season,

and this has probably taken thousands of years of genetic adoption;

the plants put everything into the chance of bearing seed;

I do not think they are capable of overcoming their genetic inheritance, and regenerate.

Indica and sativas, the other two land races of cannabis come from warmer, more variable climates, where the winter could be wild enough for them to survive and regenerate in the spring, when the days are longer.

This has never been a possibility for Cannabis Ruderlartis.

hence, why I think Jay is right.

I would love to be proven wrong through!

happy regenerating,

john

Hey John ,,

As you know I'm going to try and regen my Ice dream ,

I have a few stupid questions my friend !

What humidity would you recomend through the turn ?

There will be a lot of dying flowers there if all go's well !

How long should I expect to be on a 24 hr light cycle before she turns ?

I know this can take a while so even a rough idea is good !

Blessings ,,,,,

humidy si think should be normal around 50%

the plant will have a large root system but not much on top, so do not water her much, just one good watering with a grow nutrient;

on 24 hours of light, she will show very quickly with a week, and new growth will show itself at a guess within 10 days to 2 weeks;

post on it, and I will be able to let you know when she is returning to veg;

good luck,

and take care,

john
