FAQs
What is the benefit of the Donut Ring technology?
The Donut Ring acts as a water chamber that ensures your dripper is perfectly placed every time, leading to more uniform water distribution throughout the entire block.
How does Optidrain improve plant health?
Optidrain technology enhances the drainage performance of the rockwool, preventing stagnant water at the bottom of the block which can lead to root rot and other pathogens.
Can these blocks be used with other Cultiwool sizes?
Yes, these blocks are designed to work as part of a system. You can easily transplant from Cultiwool Macro Plugs or 4 inch blocks directly into these larger 6 inch cubes.
Does the foil wrapping need to be removed?
No, the black/white foil wrapping should stay on. It is designed to prevent algae growth on the surface of the rockwool and help manage light reflection and temperature.
Are these blocks suitable for commercial hydroponics?
Absolutely. Cultiwool is known for its high-quality European stonewool which offers the consistency and reliability required for large-scale commercial cultivation.
