Is there a scientific explanation for discontinue beneficials 2 weeks into bud?

[shaggyballs]

I noticed alot of nute companies don't use beneficials (fungi-bacteria) after week 2 .
Is there a scientific explanation for the discontinued use of beneficials 2 weeks into bud?

 

[LyryC]

Yes. Beneficials need time to establish the microbiology of the medium. They need to eat and poop and keep the cycle going before the plant can use their work. About a week or 2 and their in full throttle as long as they have the carbs they need.

You should stop using them because you waste them. You already accumulated enough through veg and now should just be feeding them carbs, molasses, depends on your nutes/medium. But yeah, if you want to add them, too late, but you should have been using them through veg, allowing them to establish themselves within the medium and at the roots.

Need enzymes in flower, to clean up/feed more.

 

[Granger2]

Yeah they should be established by then, if conditions and sugars are right. If you're using ACT's you're adding to the herd. I'm not worried though about wasting them, since it's a minor cost, and I want to be sure their numbers are high. -granger

Thanks


I heard flowering nutes will kill them also
At what ppm will nutes kill them off?

Is it just phosphorous that is harmful?

 

[bubblebert]

Salts in general are harmful to the micro flora. High levels can cause osmotic shock and kill your beneficials. I'm not sure on ppm's, but I try to stay below 10 on the N-P-K scale (except for a couple fish products.)

It may not be wise to be adding alien beneficials at all, in the same way in that it's moronic to go and introduce your hybrids to foreign cultures, when you know the temporary excitement caused by the introduction, will have undue influence upon the populous. My friend Butte was growing/multiplying his own naturally/locally occurring beneficials in the woods nearby his house, this is where it's at, imo. Beware of the well intended hippie, for he knows not what he does.

i stop at 4 weeks and i think its because it'd be a waste to continue to feed the roots when they are already developed to that point if you know your pot size and veg time then you will know what your working with, although ive heard its not good to have too much N going into flower and if you make your soil premixed with N then its a good idea to hold off flowering until the fill out the pot, that being said they need some N going into flower and the beneficials make it easier for them to access/breakdown along with other nutrients but when well established into flower this shouldn't even be considered a problem

 

[Tom Hill]

Ie the way (Toa) of it is this.. If it does not occur naturally in your local environment thus far then there is no cause for it to. But at some point, there may be cause. When there is, it would be really nice if there was still some outside/divergent material to introduce. So, please, if you have you eyes on the big picture, respect the significance of introducing outside germplasm into your environment enough so as to not do it willie-nillie. Peace, love, and donny osmond you damn hippies.

so your saying not to dump my soil outside if i've used superthrive because there might be a chance that the micro will throw my local ecosystem out of whack?


hell well i'll just take it to the experimental forests...if i cared that much, because i really wouldnt mind those bacterias being where i dump my soil because i really just dont think it's that important. maybe when microscopic bugs start dying and eventually birds i'd consider, as of right not there is no indication that these microorganisms destroy MY local ecosystem on a level larger than a grain of rice IF that.

 

[Tom Hill]

I thought superthrive was mostly just hormones and vitamins, fuck that shit goes back further than rollerskate rentals lol. Let's put it this way, if you are hungry and you live where apples are ripe now, you should be eating apples for lunch,, not imported jumbo shrimp from Australia.

 

[new3]

lol, i heard that! but when we reference this down to a microscopic level its a little different especially when your starting from scratch ie: indoor, i dont want to introduce outdoor soil into an indoor growing environment. lets put it this way, im living in the mojave desert, i can't get even a cactus pear because the harsh environment won't allow. But i would rather order fruit than not eat. im just referencing for indoor growers, its not my place to say what anyone should and shouldnt introduce into their outdoor growing environments but when you take that out of the equation there is still a basic need for micro.

I highly doubt any of the micro i used was sourced from any divergent material i only rock superthrive and bio tone.

but good discussion it deffinately leeds an eye into a deeper understanding of invasive species even on a micro cellular level

do you have any examples of certain companies micro that should be avoided?
Edit: dont know if i should be asking you this, but is there a way to find source material in a specific environment and replicate to the scale of actually being plausible for use in fertilization of larger scale(how would you farm your own micro from scratch sourced from a local environment)? if you have any knowledge i'd love to know so i can start making my own

 

[Tom Hill]

really, in a two+ month situation, it will be of such insignificant worth, as to go ahead and bypass it. It's like tryna suck blood from a rock.

 

[Tom Hill]

give 3 points to soil chemistry instead of biology in these short duration grows, and be leaps and bounds ahead.

 

[habeeb]

my schedule is as:

-sometimes, no inoculation. just didn't feel like it
-sometimes 1 time inoculation


I am one that thinks bacteria have no problem in salt environments. look at bio hydro, they know the system has them because pH level get's locked. also when I think of a piece of coir at microscope level, how would bacteria not just get in there..

I was 'trained" at organic section, even if you didn't inoculate with a product, spores and shit in the air will inoculate your 'soil' just having it sit there. there is no such thing as a sterile environment, even look at any hydro person to tell you this.. especially the ones fighting to run a dead res...


but to sum it up, I think even doing more then one time is a waste of money. but I will go to say it is fine if you want to buy it, as there is many species that I don't think would end up in your 'soil' just letting it sit in the air.. take a look at some of GHE work with bio sevia, they run hydro in greenhouses in summer France, and no root rot or any problems.. they attribute it to the bennies.. but then I will go to say they have been running the hydro systems without bio sevia / inoculations before bio sevia was created, or they used bio filters..


once again, I think it's all for a money making scheme, but going in knowing that bacteria multiply at a rapid rate, don't use it every feeding, or multiple times..


my take anways

 

[new3]

here's my take, i dont buy a particular product JUST for their micro, but when it is an added ingredient i stop feeding the plant 4 weeks into flower

veg - bio tone starter plus + super thrive
bloom-4 weeks just superthrive

both of these product do not solely rely on their micro-organisms but you do have to know they are there so you know when to take them away

This is exactly what I'm trying to figure out. It would seem to me that even fermented plant extracts, and guano teas could contain a high enough ppm to harm the herd. Making products like Gen Organics or Roots Veganic products harmful as well.
