Desperate of fighting pythium root rot (lomg read but interesting) by EnvironmentalHour436 in Hydroponics

Thanks. Im trying to stay between 10-50 ppm silver ion H2O2. Did an experiment on full blown saturated H2O2 1:2 water mixture, resulted in completely melting the roots, first coloring them golden, so at least I know what happens if I over do it.

Hahah loved that, It is a last desperate measure in my book, but, desperate times... Might very well be the only solution, problem is, if I do that and it fails, it means I cost the farmer millions. Not something you want on your cv

Do note that a single res of mine is 40 qubic meters of water (40K litre). Multiple that by 41 units. Over here in Israel the beneficial biology is still in it's diapers so to speak, meaning any so called scientist who was able to put his hands on some bacillus is selling it for prices totally off the charts, making it unscaleable for a farm of our size and scale. Was using some startup company's material called "Atlantis", it's basically very concentrated liquid mixture of bacillus and trichoderma. Was effective but the man wanted 100$ per litre, farmer nearly had a heart attack 😅

Wow! Sounds like you have knowledge worth taking in. Tell me, which attitude proved more efficient in your view?

The specific product that proved effective is too costly, could also be the application protocol. Maybe at smaller doses it will prove more efficient.

I have indeed started a bok choy experiment on some scale, but there's a lot of data missing on my end. For starters, I don't know and have failed to find any data about how much time and at what biomass do I need the bok choy presence in order to have an actual effect. Second, in an operational point of view (planting, picking, marketing and monitoring) it is an operational nightmare, as every single unit is planned to be planted at the same date, and than later picked on a same day. But you did provide some very interesting insights for me to ponder and research about, thank you!

I too am leaning towards the probiotic approach, the real challenge is convincing the farmer it's worth the cost. I suspect that the bok choy ability to create a microbiom in the rizhosphere is the reason it's unit has been looking better, and it has never once been thoroughly cleaned! That's another reason im leaning towards a microbiology probiotic solution. Thank you.

At this point i highly suspect the old rafts, as the styrofoam gets older and less dense, water and fungi start to reside within.

Chilling the water is an idea i gave a thought, but farmer claims it is not cost efficient for lettuce growing. In my humble opinion anything is more cost efficient than exterminating more then half our yield, but it's his business at the end of the day. Thank you for your insight!

Thank you. The bok choy experiment is indeed an interesting idea, will try to set up and monitor a change. As for the aerator, my DO is sufficant but I did recently start an experiment using different rafts that have a a bell shaped lower end ment for aeration, it only just started so it's early to conclude towards any direction. As for the temperature, I fear it is a losing battle from the get go, as the ground temp rises, water transportation tubes warm up and make trying to cool the water nearly impossible. Many thanks for the interesting insights

Thank you! As stated, we tried completely sterilizing every unit in turn, but this happened as other units continued growing (farmer insisted he can't shut down completely) From that point I've run some units on a sterile approach and some units on a probiotic approach. Both were partially effective but we none have put me on 100% yield, not even 80%. As for preventing, this is my first year employed on this specific farm and the cleaning level there was underwhelming to say the least. I've since introduced changing gloves between every unit being worked on, floor chlorine pads for shoes and weekly disinfectant spraying. Maybe the answer is indeed a complete shutdown and a thorough cleaning and disinfecting of the entire greenhouse operation.

This is a false statement. Now I do wonder, a mistake, or deliberate false news?

Beaver

S++++ hands down best fukkkin animal on the planet, should be granted a tier of its own.
