Grodan Gro-Block Hugo 6 x 6 x 6 is a large rockwool block made for transplanting established plants into a high-performance hydroponic root zone. Its size gives roots room to expand while the rockwool structure maintains an excellent balance of moisture retention and oxygen availability. This is a popular choice for drip-fed hydroponic gardens where growers want clean, consistent media and strong root development through longer crop cycles.
