The Grodan GR32 Hugo is a 6 x 6 x 6-inch stone wool block for growing full-cycle vegetable and fruiting crops in a hydroponic system. Each block has a planting hole sized for a 1.5-inch A-OK or Macro starter plug and comes wrapped in plastic. The improved stone wool is built for more even water and nutrient spread and easier re-wetting after the block dries back. It suits growers running drip irrigation who want a large, controllable root zone and track block weight and EC through the cycle. Against smaller starter blocks it holds more water and buffers swings better, but it needs pressure-compensated drip and careful saturation to avoid oversoaking.

The Grodan GR32 Hugo Gro-Block is a 6-inch stone wool block that gives full-cycle crops a uniform root zone. It is made of improved stone wool, which helps water and nutrients spread more evenly through the block. This case holds 64 wrapped blocks with a plastic covering.
The large growing volume suits most vegetables and some fruiting plants through the crop cycle. The block's improved re-wettability makes it easier to restore water concentration in the substrate. It also helps growers monitor and manage water content and EC. Each block has a planting hole sized for a 1.5-inch A-OK starter plug or Macro plug.
To use, saturate the blocks in a nutrient solution of about 1.5 EC and 5.5 pH. Apply it with a coarse spray or by submerging the blocks for up to 2 minutes. Do not leave them soaking. Record the wet weight at saturation and track block weight during the cycle. Then insert a well-rooted starter plug into the hole.
