Hi all, I'm currently using TPN+ but after researching dry ferts on here I feel I'm now ready to take the plunge, more than anything to save my bank balance. I have found someone that sells 1kg Potassium Sulphate 1kg Potassium nitrate and 1kg Mono Potassium Phosphate for 18 pounds including delivery (unfortunately from ebay though). Is it worth avoiding these or are they exactly the same chemical make ups and do the same job as every other powdered ferts I have looked at? Are they a good deal? Just need to find somewhere for trace mix now and I'll be making the switch
