It
helps me to avoid some spam.
I receive a lot of questions and many ask for advice on the best type of hydroponic nutrient for a particular application.
I use a commercial product and follow their instructions to the letter, nutrient design is a potentially very involved science.
The nutrients available from the suppliers you see advertising on my pages will in the most part be very good and don't have to be too expensive.
But seek the manufaturers advice, as to achive the very best performance nutirent can be tailored to the plant you are growing.
