Add some calmag???Hello people I was watching a video on YouTube the guy was saying his plants could handle more light when he upped the ratio of nitrate nitrogen to ammonium nitrate, he was in a drip system in rock wool so basically hydro, that got me thinking
I then messaged Harley smith of npk industries and he said the same as I was thinking about buying the raw nutrient line he recommended not to as I’m in dwc.
What nutrients or powders can you recommend which have a high nitrate to ammonium ratio which will be good for hydro/co2/high intensity light?
Good stuff brotha! Gracias‘For many plants - especially fruiting plants like tomatoes or cucumbers - the ideal ammonium to nitrate ratio has been established to be around 2:8 and this usually implies that pH will tend to increase as a function of time since the amount of anions absorbed will be larger. Using larger ammonium to nitrate ratios - like 5:5 - may bring you more pH stability but this may be at the cost of crop productivity.’
‘In the end the nitrate/ammonium ratio is perhaps one of the biggest weapons you have in controlling how your plants change the pH of your nutrient solution. However aiming for the most stable pH - in terms of cation/anion absorption - might not be the best bet since this might reduce your crop's yield. At optimum nitrate to ammonium concentrations most crops tend to experience some moderate pH increases as a function of time. Nonetheless different crops respond to ammonium to nitrate ratios differently so you might want to give different ratios a try to see what works best for you, both in terms of yields and easiest crop management.’
