HYDROPONICS Grow Media -Size 1"x1" Rockwool / Stonewool ( 200 cubes / pack)

Product Details:


  • The renewed starter grow plugs result in a maximum number of usable and homogeneous seedlings.
  •  Both form and strength have been substantially improved for good machine and manual processing. 
  • Whether sowing or transplanting, the new plug is the solution to achieving homogeneous sowing. 
  • Grodan A-Ok plugs are designed for seed and cutting propagation prior to transplanting into  larger growing media. The V-shape design of the plug discourages tangling of roots between the plugs in the A-Ok plug sheet. 
  • Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. 
  • Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages.
  • Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. 
  • Seedlings started in starter cubes are easily transferred to larger blocks or any other media, if desired.
  • Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
