Dr. Hornby's Piranha is a  perfect companion for the Doctor's Voodoo Juice:  The juice provides your plant's roots with beneficial bacteria and Piranha provides 24 different fungi that will benefit your plant's roots.  Roots are unseen and neglected by most growers but they  are absolutely essential to plant vigor so they grow lager, and uptake more water and nutrients.  

Dr. Hornby's exclusive formula contains 8 species of trichodermia fungi, and 16 species of endo and ecto mycorrhizal fungi.  Trichodermia increase root mass, and mycorrhizal fungi can expand surface root mass by 700%.  Put Dr. Hornby's Piranha fungi to work or you and watch plants grow faster, better and stronger- from the ground up.
