    The title says it all. Im wanting to hear peoples experiences with pros and cons to raising beneficial microbes vs sterile hydroponics. If this discussion is in another thread please link me!

    Heisenberg has a great thread in the DWC section. I started brewing microbes the way he said and have not looked back.
    ETA - at least a dozen people in that thread had problems that H202 could not help, but the microbes did.

    cant go wrong with brewed microbes, good stuff & great for plants.

    Incorrectly-brewed teas can screw a whole grow up. That said, if you read a few books about teas, you should be fine making and applying them. I suggest picking up a copy of [​IMG].

    "Science is only beginning to understand the microscopic communities of plants and animals providing nutrient cycling, plant protection and plant growth mechanisms. The authors use non-technical language to describe the basic biology and chemistry of nutrient-cycling and plant-growing environments. They also include simple explanations about how to add biology to any plant-growing system and guidelines for conventional, sustainable and organic applications. Whether you're growing indoors in controlled environments and soilless media or outdoors in soil, this book helps you figure out methods for incorporating biology into your programs."

    Microbes do work in sterile media with mineral-derived nutrients, but I have a feeling you'd see more of an improvement using them with orgaincs (because organics generally don't yield as well). I found great white to be an affordable product that works in hydro, fyi.

    Is this in regard to a DWC setup or something else?

    Have you ever used the Great White in a tea or just directly into the rez? GW is what I use to make my tea along with Ancient Forest humus. I figure the $40 jar of GW will last a year and a half for making tea.

    A tea made with a focus on microbes is really hard to screw up once you understand the basic concept. You can't really overdo it with microbes (assuming you keep a diverse population) and the tea will never burn or otherwise harm the plants. My comments here pertain only to a microbe tea, and not to any sort of nutrient providing tea.


    Sterile res Pros:
    Water looks/smells clean
    no gunk build up
    no disease

    Sterile res Cons:
    Requires frequent scrubbing
    Requires chilling
    Requires light-proofing
    Requires purchase/application and upkeep of additional chemicals
    Often does not provide a totally sterile res
    Disharmonious to the grow process (though not harmful at all)

    Microbe res Pros:
    No gunk build up
    No disease
    No need for 100% light-proofing (though roots do prefer darkness)
    No need for chilling
    Only need to scrub res between grows
    Roots will be stimulated to grow and thicken
    Roots will be extended via fungal hyphae
    Microbes produce enzymes making enzyme products redundant
    Water uptake increased
    Induce natural stress and disease resistance
    Induce a slight resistance to pests, including mites
    Protects against root pests like gnats and aphids
    Products are cheap and last a long time

    Microbe res Cons:
    Microbes consume oxygen putting even more importance on aeration
    The tea needs to be made every 10 days for constant applications
    Some preparation is required; everything is not in one simple bottle
    Some education is required

    Lets not forget a microbe tea also makes a great foliar spray and helps protect cuttings from damping off.

    This is what I can think of for now, I invite anyone to modify.

    after transplant from soil to hydro, i used h2o2 at 7 ml per gallon. is this enough to throw off microbes? i think i will go with the microbe res, i should probably replace the whole reservoir before proceeding correct?

    I think 7mL of H2O2 would not be good for microbes...
    If there is residual H2O2, which there prolly is, you should change that out before putting in beneficials.

    H202 can take up to three days to completely break down, but probably falls below fatal levels after 12 hours. One should always make a fresh res before adding microbes the first time though, just in case some harmful bacteria already had a foothold.

    Sterilized soil offers no nutritional value because microbes are not present to break down food. You would have to supply synthetic ferts. We do not replace microbes by adding ferts, but by adding microbes.

    * ever since i switched to this method of growing.. no more PPM/EC, no more pH, no morre nute burns, healthy plants 24/7, roots look like monsters-- i dont use light covers at all (ill take a pic on how massive the root system gets ;) i <3 microbes

    right on, thats good to hear so many people are enjoying this method

    I would have recommended a sterile grow much easier ..no pH fluctuations cost less to do.. grows bigger buds and more potent bud
