In this video I explain what the Masterblend formula is and how I mix it up for a one gallon recipe. I also cover the basics of NPK and what the numbers 4-18-38 stand for. I find this hydroponic nutrient solution works very well for my fruiting plants such as tomatoes, cucumbers and peppers. It is also very economical since you use so little at a time.
