Product Questions & Answers
1. How many pallets are included in a full truckload?
A full truckload contains 20 pallets. Please have a forklift onsite at the scheduled delivery time to unload the pallets from the truck.
2. What is the planting hole used for?
It provides a placement point for a compatible rooted starter plug, allowing roots to develop into the surrounding stone wool.
3. What does electrical conductivity tell growers?
Electrical conductivity, or EC, indicates the concentration of dissolved salts in the nutrient solution. Monitoring it helps growers manage feeding conditions.
4. Are these loose individual blocks or wrapped strips?
This offer is for the wrapped-strip configuration. The stated case quantity counts individual blocks, not strips.
5. Why does moisture distribution through the block matter?
More even moisture distribution helps roots access the substrate throughout its height and supports more consistent irrigation management.
