Sterile Flood and Drain, compatible nutrients.

Hi guys,

I have decided to switch over using sterile system using H2O2 as the sterilising agent at 35% ~1ml/L twice a week. I am wondering what nutrients, additives, are compatible with sterile hydroponics? My plan will be to use Canna base nutrients with no other additives. What works with sterile? Do Fulvic/Humic acids break down with H2O2? What about enzymes like Rhizotonic? What other additives should be avoided with sterile Hydroponics?

First post, thanks to everyone here for sharing their knowledge. Much appreciated.

Cheers

Stick to strictly salts. Anything organic at all is a no go.

Try Jacks 321 Hydro. Best thing I ever did was switching to Jacks away from nutes with organic ingredients. Organic anything and hydro = bad.

Thanks! What I guess my actual question is ... What is organic? Anything that is not pure salts? Just for example, out of the Canna range would the only compatible additive to Aqua Vega/Flores be the PK13/14 ?

Pretty much all you need. If you haven't already bought them, save your money and get a gallon of each GH FloraTrio Micro/Gro/Bloom and CaliMagic. Cannabis is stupid expensive and no different than anything else.

I would like to try GH but it is not easily available for me. I am thinking of transitioning to Canna or the Nutrifeild A/B.

I have been using a local shops mix of grow/bloom, some Si, FlairForm CMX (recently removed with no problems) with nutrifield BudBirst/Veg Ignitor as additives which are sludgey brown fulvic mix. Since I am going to start using H2O2 for the pathogen control, I think I need to stop using BudBirst/Veg Ignitor. Are there any other additives that are common for styrile hydroponics? Or are we just playing with ONLY salts, not enzymes, acids, ect?

ONLY SALTS. PH downs are usually all acid based but that's fine.

What part of the world are you from ? I run a modular flood & drain, and I've tried a few things. Some with success some without.

Don't use Enzymes ! Nope

Don't use anything with Humic or Fulvic Acid

Just say no to beneficial bacteria, regardless of what people say, you're asking for a major headache.

Find a good H2o2 product ( I use Silver Bullet Roots) works out cheaper and works better than standard H2o2.

Growth Technology Ionic Hydro nutrients are perfect. 1 part Grow and Bloom. Clean ( I'd love to try Jacks 321, but can't get it in the UK )

Shogun Hydro Nutrients run very clean and I've had good results with the base nutes the silica, root stimulator and cal mag. The Pk from them I don't like at all and neither do my girls, seems like they start to regurgitate every time I give it to them.

I think canna has organics in it. Go with jacks, floraflex or current solutions. Can use MKP as a bloom initiator in weeks 1-2. Then use potassium Sulphate for boost in weeks 3-8.
think about using UC roots, pool shock or making your own hypoclorous acid, better then h2o2.

Canna is uses in flood and drain by MANY growers

The reason behind using only salts is that anything that is an organic molecule, the peroxide will attack, break down and then you are left with nothing to oxidize your pathogens which is what you were after in the first place.

Thanks for the responses, I have a good understanding of the WHY with H2O2 and I have tried running bleach/Sodium Hypochlorate (Aka pool shock) with success too. I have removed all humic/fulvic looking additives and just have Si, CalMag and the base nutrients made from my local store (who didn't even know what H2O2 was, they are a resailer of autopots and are not really interested in other forms of hydro) so I am considering a longer trip to get some nutes that have good reputation.

My options appear to be Canna Aqua or Nutrifield Elements. However both of these appear to "enzymes", "acids" and other random things in there which might not be compatibile with H2O2/Sodium Hypochorate.

I also seems the additives for these lines of nutrients are organic in nature. So I will not be adding them either. I want to use Silicon / CalMag / Base.

Does anyone have experience with either Canna Aqua / Nutrifield Elements in a sterile environment?

Also is there a difference between using H2O2 and Sodium Hypochlorate? Can you use Sodium Hypochlorate with organic additives?

Nice, what concentration worked for you?

I have a small bag, but haven't used it yet, because post-purchase research said that the pool shock people were using was calcium hypochlorite, and the only kind I found was sodium hypochlorite, which was just bleach in dry form, and worse for the plants than the calcium hypochlorite.

Sorry, I have used both Sodium/Calcium Hypochlorite. First in the form of bleach and second in Pool Shock. Have not noticed a difference between the 2 so far. I have only recently started using these products and my success/failure is only anectdotal. I have moved to using H2O2 to remove the biproduct of Hyphochorides (H2O2 gives of oxygen as it's bi product). However, I have heard cases for both products based economics and plant health.

I am happy these products do their job, since my plants are no longer dieing. However I have had to change my feeding regeime and I am not fully happy with the health of plants. I am now searching again for best nutrients for sterile.

I am leaning towards trying Canna Aqua due to the weight behind the name. I am aware of the cost, but at least I can at least bench mark off this nutrient and then go searching for cheaper/better alternatives.

I hope this thinking is sound. Is there another way I can explore this problem area?

CANNA AQUA contains Silicates, humic and fulvic acids, and algae extracts that lead to even better performance

I guess Canna Aqua is out?

I was using the Stickies in this thread for inspiration with my H2O2 usage.


Mr Al.B uses H2O2 with Canna Substra. Does this have organics in it?

Not every substrate is usable if you're growing on a recirculating system. Also, there is a reason there are special nutrients for this growing method.
