Which strains refuse to reveg and WHY?

[Douglas.Curtis]

Many of you have revegged plants, and I have revegged a growing number of them myself. Since I am relatively new to this, I wonder about strains which do not reveg and the reasons why.

Is it only autoflower genetics which cause the non-reveg ability, or is there something in photoperiod strains which also prevents it from happening?

Wonderful plant process though... I really enjoy watching the progress of transformation.

I am not an expert in revegging by any means (Although my nickname is a play on the word reveg lol). But I find this subject very interesting as well. I have failed to reveg plants that I am sure have no autoflowering genes in them. At least as sure as I can be.

This caught my attention though: are you sure it's a strain thing? Or is it a individual plant thing? The reason I ask, is I would assume that because the change from flowering back to growing is caused by a hormonal shift, maybe it could be more dependent on the plant? The same way some plants are easier to reverse than others, this process is also dependent on hormonal balance if I'm not mistaken.

Another silly thought: what about using plants that fail to reveg for an out of season grow? If they ignore the change in light hours, maybe they could flower uninterrupted through may-june?

Lastly, here is a pic of a plant I grew last year (Kali China), she started revegging with maybe 3 weeks to go, because I miscalculated and thought she would finish before noticing the increment in day hours. This was mid may if I remember correctly. The other ones thankfully finished before starting to reveg.

Not sure, and great questions.

My lebanese/church cross 'Lerch' will reveg very easily, and I have noticed many harvested 'stumps' in the past attempting to grow new leaves and branches. Trying very hard and putting out single blade leaves.

I have many more questions than answers at this point. Story of my life. lolol

I agree - ease of reveg often seems like an individual plant thing - or even an individual branch thing.

I recently coaxed 3/4 sisters grafted together back into vegetative growth. They were S1s, too, so more closely related than most.

I only have a couple of pics. This one shows three of the sisters.

The scion with very weird growth pictured in the foreground here succeeded ('though not from this growth). A bud from another scion (top left), also made it - she's just starting to really show, here. The browning bud partly visible in the upper right did not make it. It slowly further browned, but no other changes ever appeared.

I let her flowers get pretty mature, maybe just starting to die on the vine, before harvest. The one that failed was the most visibly 'done' at the return to a long day. Because there are so many strictly environmental factors that can make a plant frail before its time, I bet that genetic effects are often swamped by external influences.

It would be very neat to see photoperiod sensitive seed varieties that showed uniform failure (or almost 100% success) consistently!

It's also interesting that it's a cross with a Lebanese plant, because Lebanese landraces or at least some of them have some autoflowering capabilities, "semi-autoflowering" as they say in Ace seeds' website.

"Although its flowering is moderate (9-11 weeks), this Lebanese sativa matures early (at the end of summer) due to its semi-autoflowering tendencies, which mean it begins to flower after about a month and a half of life."

Apparently this behaviour is common also in hashplants from other hash producing countries, like Morocco, Syria and others. Not sure if it's because of the latitude or some other reason.

Is it only autoflower genetics which cause the non-reveg ability, or is there something in photoperiod strains which also prevents it from happening?

This is almost difficult due to the inability to clone auto-flowering DNA. All auto-flowering genetics must therefore be cultivated from seed. Autoflowering cannabis or day-neutral cannabis cultivars convert from vegetative to flowering growth as they get older.

I find that strange as well. It does indeed flower automatically when root bound. It also reveges very easy, when you chop flower and root ball and replant in fresh soil.

So -not- the autoflowering which prevents reveg, apparently. I've revegged one female twice now, so at least the genetics are capable of it occasionally. The cuts try to flower out and die though, still working on that. heh

Now that I remember, Chimera's 'Frankie's Church' also flowers when root bound, and all of them have revegged nicely multiple times as well.

I always thought that if the plant blooms too long (all trichoms are brown and the leaves begin to turn yellow from old age), it can't be returned to vegetative growth.

I have seen this on one plant that I grew a few times. It's a Critical Mass cut selected in Spain around 20 years ago (Critical Bilbo).

The guy who gave it to me warned me that it would start flowering if the roots filled the pot. He says it's because it's so old. I don't know if that's true, but it did indeed autoflower as soon as it filled the pot. The solution was doing the same as with yours, pruning the rootball, giving it fresh soil and back to growing. I don't keep it anymore because so many people here grow this same clone that I got bored of it. My friend still does the repotting of his mom every 2-3 months.

I tried to reveg a Bruce Banner that had gone for 12 weeks flower but it failed, this may be the reason.

The strain I had the best results with for re-veg was the old Giant Bogglegum from the early 2004 beans. It was an absolute beast. I would leave popcorn buds on branches after harvest and patiently wait giving 24 hours light, and very lightly misting those left over popcorn buds twice or even 3 times a day with a potion of H20, mycorrhizal fungi and grow formula . In around 30 days later, the bracts on those popcorn buds will pop open revealing new growth. Each bract that pops is like a separate plant, and growth can become quite crowded and vigorous.......

You will get increased yield and potency if everything turns out right. The growth though will appear a tad on the freakish side, but that's OK........... pictured below is the same Bogglegum monster re-veg from different angles. This particular plant was grown using aeroponics, which greatly contributed to the end result you see here.....
