Plants And Kh

[riksworld]

Hi guys,

Was woundering if anyone know exactly what optimum KH for plant growth is?, im currently doing a planted tank and would just thought id ask as i dont want them to die

it depends on the specie, i've known people have planted tanks with a Kh of 14d/ 250ppm

If oyu inject CO2, it will bring it down anyway, for plants to survive concentrate on:

light
ferts
CO2 (optional depeding on other factors)
