SUPERTHRIVE

[latewood]

I've been growing indoors for 30 years .. Im no 'expert', but I have done enough crops to know what to expect ... this is my first grow using SuperThrive ... following label directions, much like you all have ... my plants are in excellent shape, like always, ... and I see NO difference with the SuperThrive ... if it has done anything beneficial, it isnt evident to me ... I'll probably keep using it, since it could be doing something discreetly, but I surely doubt it affects sexing ... in fact, this crop had one male, and that is only the 2nd male I have gotten in 30 years ... purely coincidental, Im sure, but something to ponder ... :smokin:

I've run across this several times and must comment.


I feel that your observation is all the more reason to use Superthrive. You are not supposed to notice anything other than a healthy plant. Imo.

I have pondered this query...

I think people misconstrue Superthrive...I don't believe it to be a producer of monster 'bud', but a stress relieving vitamin mix that keeps the plants happy/healthy. Imo

It took a while, but that is my take on Superthrive.

When I 1st read up on superthrive, I decided to use it because it is a stress relieving "elixir", so to speak...
Matter of fact, I originally bought it to relieve the stress plants experience through transplanting.

One of the 1st rules of successful cannabis growing is; What?
Keeping the plant stress-free if possible. It is the key factor in early development to produce fem's...[big:thumbsup: tip]

So, If an early stress free growing environment is the key to more fem's...then we can assume that Superthrive, with it's stress relieving tendencies...Helps to create more fem seedlings. That addresses the male/female ratio debate...again just MO.

I would like to add...there are several factors* that are overlooked in this debate. Factors* that are relevent and have been proven to cause more or less females in seedlings.

*There was a study** was done by Henk, owner of Dutch Passion, on their feminized seeds. If it goes for feminized seeds then it goes to regular seeds in my opinion. (Check out the "had to be said" thread in the grow lounge...I posted a report from "dutch passion" that explains the experiment/results)

**source-information came from page261 section2 chapter8. Indoor Marijuana horticulture; Better known as the Indoor Bible. Buy one @amazondotcom

OK, I will post this and let it sink in, talk to you folks, later lw

I have no firm decisions on the stuff, one way or another, it could very well be like you suggest, maybe the Superthrive only makes itself obvious when there is a deficiency ... very possible ... I may start some seeds in a few days, depends on what my present clones do ... I will NOT use the Superthrive on one plant, and see if I can see a difference ... if anything develops regarding the Superthrive test, I will post it up ... :thumbsup: ...... :smokin:

Supposedly, the Vitamin B-1 in SuperThrive and other products doesn't do shit for roots whatsoever. The naphthylacetic acid and some of the other components in it, however, does. Read the excerpt below for further details.

The Myth of Vitamin Stimulants:
"Vitamin B-1 reduces transplant shock by stimulating new root growth"[/align]

The Myth
Ever seen this advertisement? â??[Product X, which contains vitamin B-1] stimulates the quick formation of new root hairs and revitalizes the delicate feeder roots that are often damaged in transplanting. [Product X] is especially designed to hasten the development of bareroot roses, shrubs, shade trees and bedding plants that have been moved to new locations. It helps plants become established quickly and ensures vigorous growth.â?� Another adds a little scientific terminology to convince you: â??Vitamin B-1 (plus minor elements and chelating agents) is great for root growth and helps reduce transplant shock.â?� Or how about this one? â??The combination of Vitamin B-1 with essential micro nutrients forms a highly effective mixture...and lessens the chances of transplant shock and plant stress.â?� Arenâ??t you convinced that if you donâ??t use products with Vitamin B-1 your transplants will suffer? Apparently administrators at one large university are. Under their â??Typical Tree Protection and Relocation Specificationsâ?� is the following: â??48 hours prior to cutting, an application of vitamin B-1 shall be administered to the rootball of the tree.â?� If a university requires this practice, it must be legitimate, right?

The Reality
Applying vitamin B-1, or thiamine, to root systems of whole plants does not stimulate root growth. This is a myth that refuses to die, though it has been repeatedly refuted in the scientific literature. To understand why, it helps to think about this in a historical perspective. Many decades ago the plant growth regulators called auxins were isolated and characterized. Auxins were found to stimulate cell elongation in both root and shoot tissues. Commercial preparations were developed that contained auxin and vitamin B-1 among other ingredients. Research in 1949 found improved root development in plants treated with one of these preparations (Transplantone, which contains both auxin and thiamine), but noted the importance of auxins in this response. Further research throughout the last half of the 20th century investigating the application of auxins to root systems suggested that auxins may stimulate root growth, but that vitamin B-1 on its own does not. So what does work for stimulating root growth and reducing transplant shock? A review of the historical and current literature suggests the following:

Indole butyric acid (IBA) is one of the most common auxin formulations especially in tissue culture. In cuttings, it has been found to increase the number of roots, to increase rooting percentage, to increase both parameters, or to do neither. IBA has had some success in root regeneration in transplanted trees; it may help redirect resources to the roots by suppressing crown growth.

Naphthylacetic acid (NAA) is also a commonly used auxin and often the active ingredient in commercial preparations. NAA tends to be toxic to seedling root development, as it inhibits primary root growth and enhances lateral root growth. This latter activity may account for NAAâ??s success in regenerating roots of transplanted and root-pruned trees. Like IBA, NAA apparently suppresses crown growth, which also may redirect resources to the roots.

Paclobutrazol (PBZ) is another plant growth regulator that seems to stimulate root growth in containerized as well as established tree species. Like the auxins, PBZ reduces crown growth which may assist with root resources.

Fungicides may increase root growth, but overall this is not beneficial to the plant. Fungicides kill beneficial mycorrhizal species, and the lack of mycorrhizal colonization means that plants must put more resources into root growth than they would if mycorrhizae were present. Furthermore, there are beneficial fungi and bacteria that control pathogenic microbes and roots colonized by beneficial microbes have been shown to grow more than those without.

Nitrogen supplements can improve root growth, and conversely the absence of nitrogen will depress root growth. Uptake competition from bacteria, fungi, and other plants can be intense and so nitrogen is often limiting.

Vitamin B-1 (thiamine) is an important component of tissue culture media, in which isolated plant tissues can be propagated. Its use for stimulating root growth in whole plants is not supported in the literature and one study reported that root growth was greater in the control treatment (water) than with thiamine. Plants in the field manufacture their own source of thiamine and it is therefore unnecessary to add any additional levels. Many fungi and bacteria associated with plant roots also produce thiamine, so itâ??s likely that healthy soils will contain adequate levels of this vitamin without amendment.

Why does the mystique of vitamin B-1 transplant tonics still persist after decades of scientific debunking?

The Bottom Line
â?¢ Vitamin B-1, aka thiamine, does not reduce transplant shock or stimulate new root growth on plants outside the laboratory
â?¢ A nitrogen fertilizer is adequate for transplanting landscape plants; avoid use of â??transplant fertilizersâ?� that contain phosphate
â?¢ Healthy plants will synthesize their own thiamine supply
â?¢ Healthy soils contain beneficial microbes that synthesize thiamine as well
â?¢ Difficult-to-transplant species may be aided by application of auxin containing products in addition to nitrogen, but read the label and donâ??t add unnecessary and potentially harmful chemicals (this includes organics!)
â?¢ Adequate soil moisture is crucial for new root growth; be sure to irrigate new transplants frequently and use mulch to reduce evaporation

Or at least a contact placebo effect based on the expectations of the gardener?

my babies went through a shit load of stress and i used S.T. throughout the entire grow....7 out of 8 females. 1 hermie but i knew it was a hermie when it was a baby because i found it outside and saw pistils and nutsacks ....but i ripped th3e sacks off and revegged thinking it would be a 100% bitch instead i got a chick-with-a-dick..
much love....nasty

Very intresting info kush .this is the stuff i love reading about A1 kush thanks.the postman.

heres the main bud after vegging for 1 week. white russian

After reading through the last 2 pages...I conclude that despite one guys published experiment or the ongoing debate here; Many growers use and are happy with the results of using superthrive...
You cannot tell an individual, that has grown and experienced certain positive results using superthrive, that it does not work.

However...I conclude that superthrive is another additive, that can be replaced with other "like" additives; Acheiving similar results. Liquid karma for instance. I use both ST and LK, and have also used Advanced nutrients B-52.

There is no doubt, that I have better faster germination rate with higher % females, using ST...

Now one more thing I would like to say about this subject.

You are all dedicated growers...taking the utmost care to grow the ultimate plant. Therefore, Regardless of what you use, You will have positive results...It's called 'KARMA'

I gotta go tend the garden lw

[mobay]

man let me tell you that this white russian weed is the shit.

[postmandave]

man i cant wait bro, compared to the jamiacan strain was it a lot better
as if it was man that cross with the wr will be sommit else.the postman.
