Good day, y'all! I've found a new slow-release fert formula that seems to be the one I'm looking for since slow-release gypsum ferts has unfortunately out of production here in Jakarta.
They are SAPROTAN FertiPhos and Meroke Korn-Kali B (you can refer them as FertiPhos + Korn-Kali B).
What I'm interested with fert formula is that these ferts are affordable; unlike the gypsum ones, 1 kg of each of them (2 kg in total) costs only about US$ 1. Yes, just around one dollar!
Second, they're double as a Cal-Mag fert too, therefore promising me less time to mix my Cal-Mag ferts every time I water my cacti.
Here are the components:
FertiPhos:
Korn-Kali B:
I'll plan these ferts to be mixed by 1:1 ratio, though I'm still looking for any opinions or additions from y'all.
With my times ever gone busier and busier, I do hope these ferts will do justice to my cacti as I'm still trying to give my best to what remains in my collection
I'll still consider still using my fert formula to water my cacti as I start using FertiPhos + Korn-Kali B or complement my fert mix proposal with a 43-0-0 slow-release fert. Also, I'm simplifying my soil mix by using only scoria, pumice, and zeolite. Kanuma starts to get less affordable somehow.
Wish me luck!
