Would like to ask anyone know of a good water soluble garden plant food,i am currently using miracle grow from the uk,but my stocks are nearly finished,I have seen food for sale in small bottles but it is too expensive to use,i have hundreds of plants so need something cheaper.grateful of any advice,thanks.

I don't know what they call the stuff, but it's a pink powder I buy. About 10 Baht a small packet or 25 baht a container about the size of a very small baked bean tin. The instructions are to put 1 tsp in a litre of water. I use it on my orchids once a week 3 or 4 squirts. I don't know if they are fed enough but they flower regularly on it.

Thanks Mosha for your advice.i will look into that,although i am looking to buy a large quantity...
