Does anyone know where I can buy alternative to #masterblend 4-16-38 dry #ferrilizer for #Hydroponics systems?

Prices on Ebay and Amazon (I don't buy from them) are ridiculously high.

The price of a 1,5kg pack is higher than the 5kg pack in the US.

I really appreciate your help.

Ridiculous prices of fertilizer in #France!

Buying 750g package of #Masterblend #hydroponic #fertilizer costs 69 euro from CDiscount, but in US, 6kg of if costs $39 on ebay.

It is really upsetting.
