The hydroponic grow medium you never knew you needed!

We have grown lots of plants in this grow media when we were testing it. Comfortably grow most plants in this reusable hydroponic media, chilli, tomato, lettuce the majority of herbs - even strawberries!

Designed, engineered and manufactured in the USA, the innovative TetraBase™ grow medium is a worthy investment for lovers of hydroponic gardening. 

Environmentally-conscious, Tetrabase is made with 100% recycled Polypropylene (considered to be the safest of all plastics.)

Designed specifically for commercial DWC & NFT hydroponics systems, TetraBase ™ is a clean and inert media that can be re-used forever.

TetraBase™ molecule-shaped pieces have a unique interlocking design that will get stronger as the root system grows and expands, delivering the support large plants require. TetraBase™ does not affect pH, attract pests or encourage bacteria growth- saving you time and money.  

Why TetraBase™ ?

  • Debris and dust free
  • Reusable
  • pH Neutral
  • Non-porous
  • Non-abrasive
  • BPA free
  • Economical
  • Environmentally-friendly

“The time TetraBase saves me from constantly having to adjust ph levels, as well as the time spent pre-cleaning other medias plus the fact that it's forever reusable made TetraBase the obvious choice for us at Intense Labs”

Not just for DWC or NFT gardeners, TetraBase™ is great alternative for indoor gardeners who use clay balls (LECA) for their indoor ornamentals.

How much do I need?

Allocate 1 x 320gm bag per 140mm Mesh Pot. Place your small grow cube or sponge in the mesh pot first, then carefully add the TetraBase™ molecule-pieces. Fill to the top of the mesh pot.
