SUNJOY TECHNOLOGY CO., LTD. supplies industrial‑grade rock wool cubes from Tianjin, China, designed for hydroponic and soil‑less cultivation. The cubes are offered in three standard sizes - 25 × 25 × 25 mm, 30 × 30 × 40 mm and 50 × 50 × 50 mm - allowing growers to match tray configurations precisely. Each cube is produced from stone wool fibres that provide a neutral pH environment for root development. The product description highlights water retention and aeration properties that support healthy plant growth.
The stone wool material is non‑organic, fire‑resistant and sterile, which reduces the risk of pathogen transmission in closed‑loop systems. In the horticultural industry, typical bulk density ranges from 120 to 180 kg m⁻³ and compressive strength is around 0.3 MPa, values that align with the performance of SUNJOY’s cubes. These characteristics make the cubes compatible with automated irrigation and nutrient delivery equipment.
Growers of leafy greens, herbs and fruiting crops use the cubes in greenhouse benches, vertical farms and home hydroponic kits. SUNJOY states that minimum order quantities are flexible and that shipments can be arranged on FOB or CIF terms, but exact MOQ and lead time should be confirmed directly. The product is packaged in sealed, moisture‑resistant bags to maintain sterility during transit. Importers are advised to request the material safety data sheet and any relevant phytosanitary certificates before finalising the purchase.

Before placing an order, verify the product data sheet, including dimensions, pH and water‑retention figures, and request a material safety data sheet. Because the supplier’s response rate is low, consider confirming the contact details and establishing a clear communication channel to avoid misunderstandings. Checking the supplier’s verification tier and any third‑party audit reports can add confidence to the sourcing decision.
Logistics for rock wool cubes typically involve FOB or CIF incoterms, but the exact terms, lead time and freight costs must be confirmed with SUNJOY. Importers should obtain a pro‑forma invoice that specifies packaging weight, volume and any handling instructions. Payment conditions such as letters of credit or advance payment should be agreed in writing before shipment.
Quality assurance should include a pre‑shipment inspection to confirm cube dimensions, sterility and bulk density. Request a certificate of compliance with relevant horticultural standards and any phytosanitary certificates required by the destination country. Engaging an independent inspection agency can help verify that the received goods match the agreed specifications.
