Plantastic has set an industry standard for quality nutrients through three decades now.
Plants and their needs usually don't vary greatly - only their environment will produce major changes. Our standard Plantastic formula provides for a vigorous lush growth through a generous blend of various nutrients and additives provided.
But for the use of rockwool (Vertex, Grodan, Growool etc), a minor "tweak" was needed to modify the formulation to maximise performance. Basing the modification on a European rockwool formulation, we set out to make sure we were not getting excessive salt build up through the rockwool, nor was there any gross variations in pH levels. Through buffering and balance we achieved this, and have provided a nutrient that is free flowing through rockwool and has a well buffered pH.
Plantastic Rockwool formulation is not a major change from the original Plantastic formula. To do this would be an unnecessary re-invention of a truly superb nutrient - just a few small changes to maintain maximum performance for growing specifically in rockwool.
