Where to buy dry ferts?

[gy960]

Hey guys,

Where do most of u get dry fertilisers from (not online)?
Ferts: Potassium nitrate
Monopotassium phosphate
Potassium sulfate
Csm+ B
I only know ecocityhydroponics but i could only find potassium sulfate on their online catalogue.

Thanks.

Potassium nitrate is control items in Singapore, you need license to buy it. The rest you can buy from hydroponic shop

KF,

I haven't been fertilising through the water column with inorganic salts for a long while. Can't they get it from Dr. M anymore?
