DWC pot grow - the most vital nutrient

Some growers say this others say, many different opinions… In you opinion , what is the most vital nutrient in a DWC grow?

What do you think is the 2nd most vital nutrient in any DWC hydro pot grow?

All of them are important or you will have defficiencies!

The most important is a solid pH and a good balance of nutrients. If your pH isn’t on the money they your plants will be sickly.


Calcium and silicate since they are least avail in hydro and usually plenty in soil, any base nutrient line will require the addition of both :wink:


BOOM @Donaldj Totally agree… silicate especially.


Thanks alot

I have heard of people feeding diluted milk, molasses etc. Any ideas if this is viable?
