    Default Upkeeping microbes in rdwc

    Hello all I have been using both Hydroguard and Photosynthesis plus in RDWC.

    I have been using PP for some time in coco and love it. I'm now using HG and PP in RDWC, its all a bit haphazard at the moment.

    I initially add full strength HG when the system is filled wait a few days and add half strength PP. I then just add a 100ml or a splash of each weekly (or when I remember) for up keep as I add new nutrient solution.

    HG contains only Bacillus Amyloliquefaciens @ 1.00 x 10 4cfu's ml. PP contains Bacillus Amyloliquefaciens @ 1.00 x 10 7cfu's ml along with loads of other good bacteria and mycorrhizae.

    Dose for HG is around 12 ml per 20 litres at full strength, with no mention of upkeep dose.

    Dose for PP is initially 60ml per 20l followed by weekly doses of 30ml per 20 litres.

    Any advice on the dose for these two products would be great

    Could I drop the hydroguard ?

    Do I need to keep on adding or will the population of good bacteria just continue to grow (I don't add sugars to the system)

    Would you recommend full strength in RDWC.

    Many thanks

    You really need reds to answer these questions. As he has run a fully organic dwc with good results that I've not seen before

    This is an interesting post mate. I always wondered should I be adding anything to my reservoir along with the nutes, but I was always unsure in case it affected my ec. I had used silver bullet roots before after reading such good reviews on it. I would have added it to the reservoir the first two weeks along with first feed but then never added it the remainder of the grow. Always wondered should I be adding it every time I change the res. Or am I good to just go with water and nutes and maybe add the silver bullet if it’s needed

    Hello mate if you run Silver bullet you run a sterile system so no point in adding microbes.

    I did try Silver Bullet and didn't rate it at all. The lads in USA use poolshock or its equivalent when running sterile it works out much cheaper.

    Cheers mate appreciate that advice. I got silver bullet roots when I bought my system and have never really used it. I think I added it at the start on my first grow and that was it, but thinking now I should maybe be using it throughout. However still unsure how I would use it though, says it lasts in your system for 5 weeks however I change my reservoir with new water and nutes every week, so does that mean I would have to add it every time?

    Or would I run it with just fresh water in the system for a couple of hours then change everything out and add the new water with the feed? Leaving residue in the system for the 5 weeks if that makes sense

    I've ran hg bacillus bacteria in my res to help keep root rot in check and thought it worked great and added it every res change. But I was growing in dwc buckets so was easy to swap out but expensive. Reds didn't us hydro guard but made his own from rice milk if I'm correct.
    I'll link reds in and ask him to pop in .
    He's the guy to set ya right toblue

    You will need to add SB, pool shock or whatever else you use to keep your system sterile at every res change mate especially when the warmer weather kicks in. Some people even use bleach.

    I'm hoping to get away without a chiller for as long as I can and have heard it is possible when running a live system.

    Sweet mate that makes sense, wasn’t too sure if some of the SB residue or something stayed in the system which meant you didn’t have to add it every water change. Think I’m going to run SB throughout my entire next grow after reading this thread and add it each change.

    Take it I would be checking my background ec and then add the SB, and then check the EC again before adding my nutes? Not even to sure if it affects your EC or not will maybe have to experiment a little with 10litres of water beforehand.

    Mate would you add the SB at manufacturers guidelines? I know you use a fraction of the manufacturers guidelines for nutrients but wondering if the SB was different

    I'm no expert on SB but its not a nutrient so would go with the manufacturers recommendations (which are not to clear from memory) the product is made for DWC. I personally wouldn't include the SB EC into my Nutrient solution (if it has an ec). I am no expert on running a sterile system, tried it and it didn't work for me but that isn't saying it won't work for you, I think most RDWC folks run sterile, it is what the RDWC system manufacturers recommend.

    Cheers dude thanks for the advice, yeah that all makes sense it’s always good to run what your thinking in your head by someone for a second opinion. Reason why I love this place mate

    I would drop the hydro gaurd and be reintroducing pp weekly If it says so mate.
    I only used mycorrhiza twice in all throughout the grow once at the seedling stage when they first show roots then 2 weeks after they go into the system, I would introduce lactic acid bacteria weekly though the day after res change. I didn’t really change the nutrients at all throughout veg but did in bloom weekly of course.
    I didn’t do any ph’ing on a couple grows with no worries bud if your going to ph then leave do it at res change and leave it before adding the pp.
    The LAB (lactic acid bacteria) is easy to make but most people prefer the nice exspensive bottles!

    Many thanks Redz. Looked at the LAB and will get on making some tomorrow. Few questions if you could be kind enough?

    1. How much water to rice when making the rice water, is the water cold or warm, is the rice wholegrain or white? Does the milk need to be full fat

    2. How long does this LAB store for in the fridge and does it need feeding.

    3. What is the dose of LAB per litre to put in RDWC and how often do I dose, what is the daily dose for humans and how often do I dose.

    4. You recommend dropping the Hydro Guard and just using Photosynthesis Plus and LAB will this stop root rot (nutrient temps under 23 more likely 18-20)

    I see GH do one called BM (Bioponic Mix) which contains Trichoderma Harzianum this is supposedly the dogs bollocks when it comes to fighting root rot and other root disease. My concern would be getting it into the system and keeping it alive. Maybe a tube of Bio filter foam around the epicenter inlet would work.

    Is my thinking correct? Hydroguard contains Bacillus Amyloliquefaciens @ 1.00 x 10 4cfu's ml. Photosynthesis plus contains Bacillus Amyloliquefaciens @ 1.00 x 10 7cfu's ml, does suggest PP contain just short of twice as much colony forming units (cfu's) of the bacterium.

    Be great if someone could explain as I don't understand the colony forming unit/ml (cfu's/ml) calculation.

    Hay toblue

    Hope you get the answers you after mate.
    All this micro living in hydro is way beyond me TBH. Lots of people do have good results just using synthetic nutrients but with the addition of amino acid, fulvic acid’s, vitimins etc.

    Am I right in thinking in hydro that by feeding the microbes It just then release extra potassium phosphate, amino acid’s to the plant.

    I Do you like the idea of Microbes but I just see more of benefit using synthetic nutrients at the right time when you need them and exactly how much you need to.

    Also in synthetic nutrients if you get the pacific nutrients in powder form aswell you can tweak your liquid nutrients at different stages of growth- veg boosters, starter flower boosters and end flower boosters, vitmins. you can really pinpoint precision fertiliser for your plants.

    Regarding your root rot problem, In a hydro system I think you will definitely benefit from purchasing a chiller.

    Not saying your wrong mate and by the sounds of things you know a lot more than me, just thought I’d get the post Active again . I do like talking about nutrients and feeding regimes, just figured out how to work the speech text on my iPhone LOL.
