### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Awesome company!!!

Fast shipping, great products! I've used their Megacrop for years and needed calmag due to using RO water. As all their products, it comes in cheaper and works better than any other products I've used over the past 20 years growing. On top of that the customer support is above expectations! Amazing people and company!

Really impressed. Similar review left for another one of these nutrients. Just need to try the PK booster now and I'm looking forward to it!Bought the smallest size and was shocked at how concentrated it is and it's in powdered form so it will last years in every sense of the word. The sellers site has detailed information which you can find research to back up quite easily: the nutritional profile, how it stacks up compared to other nutrients of the same type etc.
