beneficial bacteria in hydro

i have always grown in hydro and always worked toward a sterile enviroment

its my understanding that BB in hydro is generally considered a No No!

i am curious if this school of thought also holds true in a drain to waste enviroment

in a recirculating enviroment the bacterial issues would obviously work against you since the bad bacteria would fester in the res for a week or 2

but if your in a dtw system and not re-using the water would adding BB be a good thing

im just not sure ...it could be the medium enviroment would be negativley effected i suppose idk... is the issue with bacteria an issue in the medium, in the res or both and is BB additives a negative for medium

i know i repeating myself...trying to form a thought and get it out

since i switched to drain to waste i no longer have the need for bleach,hygrozyme.sm90,zone sterilizing additives...does this open a door for BB?

I've sent pm to link as to why and and why not-

pm was sent to protect this forum from commercial links...

do you use a BB additive?

also..i have read something about aminos feeding bacteria or something... anybody have anything to note about aminos and there relationship to bacteria?

thanks chatty

i tend to be chatty myself

you could post the link here...this way anyone who is curious can share in the knowledge

i dont think theres a rule against posting links...so long as its not your own plug

As far as amino acids are concerned check out the Wiki entry:

Amino acid - Wikipedia, the free encyclopedia

fwiw, when I make my own compost tea with BB, I make sure *all* the amino acids are present and especially the Vit B group.

heres a copy and paste of what chatty linked in PM

Why we DO NOT Recommend the use of Beneficial Mycorrhizae (Fungi) and Bacteria in Hydroponics!
Mycorrhizae are beneficial fungi that penetrate the roots of most plants in nature. This symbiotic relationship is beneficial in that the plant provides sugars to the fungi, and the fungi enhance nutrient uptake for the plant. There are two major groups of mycorrhizae: ectomycorrhyzae and endomychorrhizae. The 'ectos' do not actually penetrate the cells of the roots, but are found between the intercellular spaces. Ectos have been found to be able to utilize a range of organic compounds such as proteins, peptides and amino acids (1, 5, 7,). However, these fungi are restricted to coniferous tree species (gymnosperms) and Ericacious (heath/ bog) species where soil breakdown of amino acids is minimal (1, 2, 5).

Endomycorrhizal fungi aid in water and nutrient uptake, especially phosphorus, but do not aid in mineralization of organic matter, and thus have not been found to take up organic nutrients (1-7). Unlike ectos, 'endos' invade root cortical cell walls and can form branched structures called arbuscules which are efficient sites of exchange between fungus and root cell. Endos are primarily associated with herbaceous plants (angiosperms) commonly grown in greenhouses and hydroponic systems (1-7).

In hydroponics, there would be little value to be obtained from mycorrhizal associations in this situation. Their value is to provide improved uptake of water and minerals from the soil / growing media. In a hydroponic setting, the plant has constant access to all the water and dissolved minerals it needs. The mycorrhizal fungi would do little to improve on a root constantly bathed in water and minerals, however may aid in nutrient uptake under plant stress and low root biomass (3, 8). Most hydroponically grown plants are of angiosperm origin, and since endomycorrhizae are not known to take up whole organic molecules in any situation, these fungi would not benefit in the uptake of a root based supplement product containing these substances. Many products make claims of enhanced growth and yield from beneficial microorganisms added to the nutrient solution along with organic fertilizers. This phenomenon can be attributed to the enzymatic secretions of these fungi into the solution to breakdown organic matter into its essential elements for uptake and transport to the roots (8, 9). Essentially, it is the same as adding extra fertilizer.

In soil mediums where organic fertilizers are used, the extra surface area provided by the mycorrhizal associations can act to enhance nutrient uptake, and to break down (via enzymatic secretions from the fungi) organic matter into its essential minerals useable by plants. Beneficial bacteria are useful in this situation again by breaking down organic matter and rendering it useful to plants in its simple mineral form. Organic fertilizers are slow acting and slow releasing, and these beneficial organisms are necessary in situations where no added mineral salts are present. However, there is little to be gained even in soil and soilless mediums when complete fertilizers with all essential nutrients are present. The use of Beneficial Bacteria in hydroponic systems can clog lines, filters and pumps.

ok so the above link says NO to BB

says it will clogg drip emitters

ok...maybe its the increased algea or bacteria that clogg things up

but arent we adding BB when we add products like aminos (dark energy), or kelp or even fulvic acid

so why are these forms of BB ok were oters are not

IMVHO - I strain my compost tea with the finest grade screen silk (I forget now the size of hole; it's tiny) and I'm convinced that any bugs/eggs/debris/solids of any kind do not get through and I've had no problems.

are you in a drip system? whats your medium?
