A Variation on K-Lite

[Ray]

I've used K-Lite fertilizer exclusively on my plants for about 12 years. I was recently in a discussion with the fertilizer pro's that suggested that paphs and phrags might do better with a bit more ammonium-based nitrogen.

5% of the nitrogen in K-Lite is ammonium, the balance nitrate. The factory blended a batch for me that's 15% nitrate, and I am experimenting with it.

If anyone else would like to play along, I do have it available.

Id like to give it a try but will it do well with other orchids too?

I don't see why it shouldn't.

Ray, how will I order some?

From my perspektiv, it should be good for Cattleyas too,
because Ammonium brings the water/substrate more to the sour side and the best PH is arround 6.5 ?!

Nitrate allone raises the PH, so from this Aspekt, it is a good choice.

I also noticed that seedlings grow better with ammonium in the fertilizer.

That's why I created my Fertilizer myself, with K-Lite Idea in mind, but not so extreme.

It works fine, but I haven't a longtime-experiance now

11,94 N - 3,72 P - 5,0 K - 4 Mg - 4 Ca - 4,3 S + TE
Arround 40% of the nitrogen is ammonium.

The PH of my RO water with this mix is arround 6,5 to 6,8 , 0,4g/l and a EC arround 400 us/cm

So, If I would live in the US, I would give the new K-Lite formulation a try
