🌲 greetings from Italy 🇮🇹

[ilSognatore]

[FONT=Arial, Helvetica, sans-serif]hello [/FONT]britannic[FONT=Arial, Helvetica, sans-serif] growers
[/FONT][FONT=Arial, Helvetica, sans-serif]in the Italian area, with some of my colleagues, we are growing with ion-exchange resins.
the resins are used in hydroponics, completely replacing traditional fertilizers.
I would like to know if anyone, who escaped from the European Union , has ever tried this system.

if you are interested in seeing how a cultivation with resins proceeds, I invite you to visit my 3D.

the plant in question is the Alice of delicatessen seeds

the resins I'm talking about are these:

I grow hydro and only use npk and micronutrients and never really had a problem with my plants... my theory is if it aint broke dont try and fix it..

Genetics play the biggest role..

This is the uk manny purple stardawg cut that i currently have in veg ...

Welcome here. Are you advertising these products?

[FONT=Arial, Helvetica, sans-serif]hello dear friend

congratulations, you did a nice job with your plants !!!
with your system you still have to introduce fertilizers in dwc vessel.
with resins must not add anything to the solution.
just add water when there is



the big difference is in this detail.[/FONT]

I'm not a promoter of the company that produces resins.
they cost so little that I do not think there are revenues.
in Italian we are experiencing this type of cultivation, and we wanted to share it with you.
I repeat that we have no commercial interest.
only simple scientific research aimed at the cultivation of cannabis. [/FONT]

We haven’t quite escaped from the eu yet ...
What exactly are these products?

 

[AgentPothead]

They appear to be fertilizer that works on basis of ion exchange. I found a few papers from the 1960s that DOW was working on but they didn't seem to follow through.

There seems to be a german company offering one Lewatit HD 50 https://www.lenntech.com/Data-sheets/Lewatit-HD-50-L.pdf I think the main take aways are that you can't leach nutrients out by overwatering and it seems to take up the unusable salts and in their place release salts usable by the plant. It seems to balance the nutrients in the solution with what's left in the resins as well,so you can't over fertilize them either.

Hey AgentPothead,
it's exactly like you wrote !!
I am also trying to fertilize my plants with these ion-exchange resins.
I'm Italian as a Sognatore.

He has opened this thread in various sections of other countries here on ICMag to figure out if anyone else around the world has ever used or still uses this type of fertilizer.

These are my plants, right now I'm in the second week of 12/12.

I have never yet completed a cycle with this method.
Now i'm going to see what happens in bloom.

As for the vegetative phase, nothing to say, the plants have grown healthy and strong, without deficiencies or excess of nutrients.
All this only by adding the dose of resin recommended by the manufacturer, once, and then adding water from the tap (not decanted) when needed, without measuring EC and PH.
It seems that everything automatically regulates itself.

If someone knows something more about this method, intervene as well.

Hello everybody!!

 

[AgentPothead]

I'm glad you guys made the thread, always interested in new ways to grow my weed. For whatever reason, it doesn't seem like there are a ton of ion exchange fertilizers available in the US so this might be a more european technique for the time being. Would be interested to see a grow diary using these if you guys have one.

I am also experimenting with my cultivation with ion-exchange resins and it's all very well.

They are a real substrate. To work they need only water, not even decanted, and 30/50 gr. every 50 centimeters of plant. End!

However, they were invented in the 1960s and experimented by NASA technicians to cultivate in space orbit. We really find it strange that no one, not even "us Italian boys", knew something about it.

To judge from these first answers I would say that for the cultivation they did not spread, in fact even we Italians did not know them.
As long as one of us has "discovered" them
To honor him, I must add that to us, the resins, made them discover "Samuraj67" ... that I thank!


However, they are very well known (and used) for water purification.

See on: https://en.wikipedia.org/wiki/Ion-exchange_resin
But you can do a lot of other research.
We would like to open our eyes to all friend growers

P. S .: big sales chains sell it to cultivate ... and we did not know it !!


Ad Maiora Semper!

Wow! It's clear that it has no lacks!

I do not speak English well, I can assure you that the resins work and I thank the guys who wrote and named me.
I use the resins for several years and I guarantee that only a few types of cannabis have problems with the resins, they do not use special water, but normal tap water.
.... you can put all the resin you want and you'll never ower from fertilizer. You will never see photos of my crops because I do not publish photos (I'm very reserved). I recommend the use of resins to those who are not experts or who like me do not have time to grow or do not know how to do it, they will take care of your plants for you.
sorry for writing errors

Man I forgot about this thread but somebody repped me and I saw it. I really wish this fertilizer came to the US, it still seems to be a European thing mostly.
