If You Want A PK (Phosphorous-Potassium) Bloom Booster Proven To Work Because It Was Made Specifically For Our Types Of Plants And Hydroponic Growing Then Keep Reading...
If you've ever tried a PK bloom booster... only to find... that it did nothing for your plants... or... it created brown spots or leaf tip burning... then... here's how to never have that problem again... AND... get all the flower-boosting benefits of feeding your plants PK.
Here's the story: many years ago, before hydroponics and indoor growing became popular, plant research showed a specific combination of Phosphorous and Potassium would make plant's bloom bigger and produce heavier harvests.
This agricultural research was performed in an outdoor environment on high-volume agriculture field crops like corn and soybeans.
And because phosphorous leaches out of soil quickly... especially... when field crops are heavily irrigated... all the PK bloom boosters were created specifically for outdoor field crop growing.
The most important thing to know is they all have more phosphorous than potassium in their formulas because phosphorous is so easily depleted when growing field crops outdoors with mass irrigation. This extreme phosphorous ratio is NOT the mixture we want.
