    Just what I was looking for to raise K without hitting N as well.

  2. Plantedrich (verified owner) –

    I like the ability to add just the potassium when I already have an excess of nitrate. Just so simple and so cheap to test when unsure of what the deficiency may be. Excellent price, service, and speed make it a great value!

    Dry ferts are by far the cheapest, store very easy and last a long time but the best part is that I can adjust exactly as each tank needs rather than adding parts I don’t want to tanks which are already high in those.

    A whole pound for $3 is very reasonable and what you get looks to be without impurities. I ordered all my fertilizers at once to save on the shipping

    There are several places to buy dry fertilizers. Nlocg is the lowest price by far. Well packaged, and great customer service. Can’t go wrong
