    Default Mycorrhizae in hydroponics!!!

    Almost any plant can be grown in soil can be grown can be grown in a hydroponic system, from trees to fruits and vegetables.

    Because no soil is used, a liquid nutrient delivery system supplies all the nutrients a plant need.
    Why should plants also need mycorrhizal fungi?
    Simply put, mycorrhizal fungi offer the same benefits in hydroponic applications as they offer in planting media and soil. Mycorrhizal fungi are good at what they do, especially in the delivery of phosphorus and nitrogen to there plant symbionts. As they do in other growing systems, fungi grown in hydroponic systems expand the effective root area into the surrounding growing substrate, be it coconut fibre,roockwool,oasis cubes,gravel,perlite or vermiculite clay pellets or other material.
    The same hyphal extension that occurs with colonised roots in soil also occurs with roots in hydroponic systems, weather plants are growing in soil, a planting mix or a hydroponic growing substrate, mycorrhizal fungi provide the same basic benefits to the host plants.

    •inoculated roots in hydroponic systems are more resistant to pathogens including,rhizobia Pythium( I think we get the message here talkers.
    •mycorrhizal fungi can create physical barriers around roots to protect them disease and pathogenic fungi.
    •colonised plant roots branch and form more feeder roots, so more nutrients can be retrieved from the surrounding area.
    •mycorrhizal fungi grown in a hydroponic system can support mycorrhizoshperic organisms that provide protective metabolites.

    Mycorrhizal considerations for hydroponic systems
    As with any growing system, for mycorrhizal fungi to thrive and benefit plants in a hydroponic system, growers must use the appropriate species of mycorrhizal fungi to colonise the plants being grown. They must also consider several other factors.

    A hydroponic system that intends to support colonisation of roots by mycorrhizal fungi must be fully aerobic. To ensure that the fungi will survive, growers should maintain oxygen levels at 6-8 ppm(for context, most tap water provides 5 ppm of oxygen) oxygen can be added to the growing environment via air stones or bubblers( alltgough hydrogen peroxide can also oxygenate it will kill mycorrhizal fungi and host plant tissue and should not be used).
    Most hydroponic systems use some form of media to support plants such as rock wool or expanded clay pebbles, many scientists use a modified hydroponic system for there studies, using sand as a growing medium and saturating with nutrient solution, but mycorrhizal fungi will grow in nearly any substrate, or even water alone if it provides enough oxygen.

    I have warned people here!!!!!!
    Hydroponic growers often add phosphorus to nutrient delivery systems, but an increase in phosphorus levels can result in decreasing amounts of mycorrhizal colonization. When large amounts of phosphorus are present in the system, at levels of around 70 ppm fungal spores go dormant and will not germinate. By monitoring phosphorus levels and avoiding adding too much fertiliser growers can encourage the formation of mycorrhizae.

    The presence of chlorine and chlorimines in public water systems can also effect the mycorrhizal growth, chlorine dissipates into the atmosphere in about eight hours but chloramines take days to evaporate and should be removed from water used in hydroponic applications. You can find this shit out yourself easy enough it's getting tiring writing stuff that's easily obtainable pmsl..

    The ph of water in hydroponic systems is also important. Most mycorrhizal fungi require a ph range of 5.5-7.0 to survive. Mycorrhizal mix packages often list the required ph levels

    I'm sorry those of you using gws as this will be a bit of a knovk back possibly.
    Have you been wasting your money talkers, I'm sure you'll have your opinions and who will brace the temps?????

    Finally maintaining proper temperatures will maximise mycorrhizal colonisation, Arbuscular(I've said the types we use somewhere) mycorrhizal fungi thrive in temperatures of 65-75(24-30), which is the ideal temperature for most plants. Growers should be aware that vesicles, spores and fungal hyphae will not survive temperatures above 120 (49). Plants would die under such extremely high temperatures aswell. When storing mycorrhizal inoculants growers should also consider appropriate temperatures.

    Using inoculants
    Hydroponic supply sources offer mycorrhizal mixes specifically designed for hydroponic systems. In these blends,spores and hyphal fragments are mixed with delivery media in liquid or powder form. To establish mycorrhizae, make sure the inoculants are in direct contact with rooted or unrooted cuttings before they are placed into the hydroponic system, or soak the starter cubes in liquid formulations or granular formulations mixed with water, as in soil, the spores will germinate when they are signaled by the root exudates.
    Many formulations can be added directly to the hydroponic nutrient delivery system; the particles within the mix are small enough to pass through systems without clogging up lines of emitters, mycorrhizal formulation suppliers should indicate the proper ways to distribute the inoculants.
    Mycorrhizal fungi do not generally reproduce in hydroponic systems, so it is a good practice to add more inoculants to the nutrient delivery system as roots develop to ensure maximum colonization throughout the life of the plant.
    How much more and how often?
    The plants can offer the answers,fast root and plant growth require more frequent addition of inoculants. Because it takes about two weeks before mycorrhizae to become established(shit think do we even ever get mycorrhizal fungi established with weekly res changes sorry) application should be discontinued a few weeks before flowering for flowering crops and a few weeks before harvest of others, such as lettuce.
    He names a load of veggies and shit here but I'll just put the cannabis people
    Claroideoglomus claroideum. C, etunicatum. Funnelliformis geosporum. F, mosseae. Glomus microaggregatum.
    Rhizophagus clarus and R. Intaraddices are successful inoculants for cannabis growing in rock wool, using mixes of several inoculants results in healthy plants.

    Hope this is a bug of useful information family,
    Hobbit I'm actually still gathering info trichoderma but if you have any specific questions I'll email the writer of the book and hopefully get them answered as he has helped me with a couple answers before.

    Good call on the sticky Bud. Red i was laying in bed thinking about this last night. Especially in regards to the res change and having to rebuild you colony before next change. Also still have nagging thoughts about how pointless it is if using synthetic nutes. I still cant find any info on the OPs comment that it will survive up to 1.5 Ec. There may be a ring of truth in it though as even organics do have an Ec. I have been sticking my pen in all sorts of organic slurries these last couple of days. Just to throw a spanner in the works mate I have come across a few articles saying that tricha is best not used due to its feeding on other fungi and bacteria. As always there are as many opinions as posts lol. Cheers for taking the time brother. In regards to questions for the author, mate id like to know which bacteria and fungi share the most beneficial symbiosis with weed plants and where these guys like to hang out in the wild. Gotta get me a microscope asap. If I can get enough info together I want to try totally organic coco grow next.

    Lol sounds like me most days and nights lololololol
    Microbe man(Tim Wilson) the one from the compost tea thread I copied from done a show and I have the pod cast for ya if you want and he says there also trichoderma is fine but we need to take into account that they eat other fungi, it's all about balance and if I'm honest the same bennies for one plant are near enough the same as any other they only really differ when it comes to the likes of plant kingdoms they come from.
    Perennials,trees shrubs etc,
    There's not that many to learn in the way of the bacteria,archea, fungi, nematodes,Protozoa they all have to be taken into consideration.

    Can I ask why you will use coco mate? It's not known to have a very good cec which doesn't get you off to a great start at least in terms of ease of growing.

    I'll get you a list of the bennies mate and these answers also lie in the another book this dude wrote teaming with microbes, these 2 books along with his third teaming with nutrients are a god send

    Lol Red you must be single as well lmao. Send me the podcast bro. For some reason that I can't figure out I cant get itunes t down load properly so i haven't listened to the other ones yet. I will try download on another computer tomorrow. Mate i just would like know to more about different species outta pure interest and cause i'm single atm. I did read an article that said they manage their own balance, and that, just for example, if the tricha eat the fungi it helps the fungi. The analogy was that of pruning a shrub the more you prune the denser the outcome. Same principal as air pots. Now while i know this to be true in stems and roots I couldn't get my head around fungi operating this way. Sooo in my mind laying in bed lol i gets to thinking how do they manage themselve and does fungi actually like a good topping. Hence my questions mate. In regards to growing a plant organic in coco, the answer is simple, I haven't seen it done mate. I'm going to try and source that book from the library. Really appreciate your knowledge and your amazing effort to get it out there mate .
    Cheers RED

    I've hesrd some good things about this working well in coco also on podcast pmsl,
    I am very much single brother and possibly the free ladies helping me get this way or at least my passion for the green kind did probably,
    The fungi grow hyphae this is where I would start a search for the fungi..

    Onto something I've been reading more about is the way trichoderma also penetrate plant roots but they tend to get there sources/food please bare with me because I'm only just goi g deeper into it still brother, from organic matter instead of root exudates,
    More to come on this for sure.
    Hectic day here soooooooo damn hot ffs,
    Gimme your email again plz H I emptied out my inbox and I'm still not to good at sending or using the emails unless it's a straight reply lol.
    I use this for podcasts seems to work really well and you can see there's a few to get through pmsl

    Just called podcast in iTunes
    Then you'll be able to subscribe and download the lot.
    It's a pleasure sharing knowledge brother it is the key after all!

    Interesting mate I thought the tricha were mostly feeding on carbs straight from the plant roots. Of course your right I expect I may have not understood the fungi topping thing , maybe its the hyphae that multiply when tricha feeds on fungi. That would make more sense. Ive had too many rainy days this week so not much work and I may be suffering from info overload. My whole desktop is covered in shortcuts to be re read. So Im gunna take a couple days to digest what I got then re read. I will pm you the addy mate. In regards to organic coco, the biggest hurdle may be getting the nutes in useable form. I wonder how quick the soil life breaks down minerals into useable form. Probs not quick enough. I did try organic coco with a tomato plant but failed.

    I will start a coco grow with you this week mate, if I was you just leave it for now, the one book will make things clearer,
    But the little head clear will help lol,
    Gotta spend the day with my daughter as I get the bonus fathers/birthday combo so the garden has to get shunned a bit lol.

    I'll get bricks of coco tomorrow and I'll get some reading done later on some coco notes, I know gypsum will be are friend here to and I think we will be using straight botanical teas, fpj's for feed with regular top dressing of some decent compost,
    This should be exciting brother I should of done this a while ago.

    Not sure what to do though,
    Plant counts at 8 but I got the 2 autos finishing now so I think I'll have to try a auto so I'm flexible with lighting.
    Soon bro

    Cool Reds, take me with you mate. I got no more room for another weed plant or desire to have another lol. But I have plenty of strong health tomato seedlings self sowing every where, If you dont mind I will grow one of those and keep you company.

    When i tried with tomatoes Red I used chicken manure and molasses teas and it failed. I expect not enough readily available nutrition was the cause there. I think that worm casting teas may be much better for this purpose. In regards to top dressing coco with compost, mate that would seem to defeat the purpose in my mind. For me the aim that would make more sense is to come up with a method that could then be used in a hydro system.

    I think you would have to in coco or hydro mate. You may just pull it of in coco but id be doubtful. I wonder what PH your soil/coco life would like mate. Adding gypsum would have to make that coco alkyline and that might kill your herd bro. Just a thought.

    I think mate that ultimately learning how to brew different blends for different growth stages would be the ultimate tbh. If I had no control at all over being able to knowingly boost certain nutes at certain times would make gardening a little less fun and challenging. I see this subject of soil life as another tool in my arsenal mate to be used in conjunction with other sound practices.

    Haha you have no idea how often i hear that mate. But when i'm done overthinking I usually end up with a result that's worth it. Over thinking is much more fun than underthinking I rekon. Mate it would be nice if we could all go organic but people dont wanna change their method when they are getting results. And fair call. Why would a guy growing monsters in his DWC stick a plant in soil and go organic? Well he most likely wouldn't but if you could come up with a way to get similar results in his system with organic nutrients then he would be more inclined to give it a crack. I always feel guilty about any run off and waste from using chemical nutes growing weed.

    Oioi Red,can you believe they had that book teeming with microbes in my library. 10 outta 10 mate. I couldnt put it down , read the whole first section and some in one sit. It is the best book ive ever read mate and in terms of gardening and soil books I havent seen any thing close. ( I have some great books on soil chemistry etc) So well written. Ive had all these pieces of info floating about my head some of it for years and the book just tied it all together. I also learned a lot of new info. Gunna finish part 2 tonight and then re read it mate. Cheers so much Red. And it seems you were right I may have been overthinking a fair few things. I love how he cross referenced info over and over through the chapters so I never had to turn back pages to re read info. Gooooood Shit mate.
