The classic Grodan Gro-Blocks have been a mainstay of professional hydroponic horticulture since their initial release in 2004. Grodan Gro-Blocks provide the foundation your plants need for healthy root development and vigorous growth.
 

Grodan’s Gro-Blocks are used in grow rooms and greenhouses worldwide. Trusted by hydroponic growers for over a decade, Grodan Gro-Blocks allow professional cultivators to grow more top quality produce with fewer inputs. The homogeneity of Grodan Gro-Blocks provides growers with a solid, consistent base for optimizing crop production. Cultivators can easily achieve a great balance of oxygen to nutrients and drive rapid plant growth. Grodan  Gro-Blocks are clean, disease and pest free, lightweight, and easy-to-use. Professional growers love Grodan Gro-Blocks because they allow efficient use of water and nutrients throughout the growth cycle.

  • Effortless start-up of propagation. Grodan Gro-Blocks are perfect for propagating young plants under a wide range of propagating conditions. The Grodan Gro-Blocks are easy to saturate and water is distributed uniformly throughout the block, for reliable root development and plant growth
  • Excellent root growth throughout the block. The Grodan stone wool ensures uniform distribution of water and nutrients throughout the block, encouraging the roots to penetrate deeply into the block.
  • Greater firmness for better handling. During the propagation stage, blocks generally will be manually or mechanically handled several times. Due to the greater firmness of the Grodan Gro-Blocks, this handling is no problem and the Grodan Gro-Block will maintain its shape and structure. The stable firmness of the blocks becomes particularly important when the blocks are placed, spaced and picked up several times during propagation.

Description

Grodan  Gro-Blocks: Available in Sizes to Suit Your Grow

 

Grodan 3” and 4” Gro-Blocks

Grodan  3” and 4” Gro-Blocks are ideal for supporting small plants throughout their lifecycle or for the early vegetative stage of larger plants before transplanting on to a Big Mama or Gro-Slab. Both size blocks are available in standard and shallow depths.

Grodan Hugo 6” Gro-Block

Grodan Hugo Gro-Blocks can support many species throughout their lifecycle. The Hugo comes with a pre-fabricated hole that’s perfectly sized to accommodate 1.5” Grodan A-OK Starter Plugs™. Be sure not to rush the propagation period and allow your seedlings or cuttings sufficient time to fully exploit the stone wool in the Grodan A-OK Starter Plug™ before transplanting.

Grodan Big Mama 8” Gro-Block

Our massive Grodan Big Mama 8” Gro-Blocks are the go-to for cultivators with the loftiest growing ambitions, able to support very large plants and even small trees throughout their lifecycle! Simply sit a plant, well-established in a Grodan 3” or 4” Gro-Block, directly on top of the Big Mama and the roots will quickly colonize their spacious new home. Big Mamas are not recommended for flood and drain — manual top feed or drip irrigation only. Adequate irrigation is critical to keep the Big Mama within the proper WC range.
