Fe2+ & Fe3+

[dannyfish]

May i know which Fe2+ & Fe3+ is better for plant intake?

i have ferrous gluconate powder & seachem iron, which 1 to dose better for plant?

I do not think it matters in terms of overall plant growth, the energy required is minimal for this change relative the the total Fe requirement of the whole plant.
0.05% of the plant vs say 40-50% of the plant for Carbon from CO2.........which would you predict is far more critical to energy demands for acquisition???

The Seachem and Fe Gluc are the same products..........

Hi,

I am pretty-sure Seachem iron is ferrous, Fe2+. http://www.seachem.com/Products/product_pages/FlourishIron.html.

As I understand it (always dangerous ), ferrous iron, Fe2+ is the directly usable form, for plants. The problem is Fe2+ is also less stable, needs to be dosed more frequently and is more likely to be adversely affected by water conditions, alkalinity in particular.

I know there have been some good discussions around here on the subject.

I mixed Feso4 with 50% glutaraldehyde and 50% water and it turned from green to dark (red/brown) next day…. :0
