Discover a versatile hydroponics starter bundle

Halatool brings you a practical, beginner-friendly kit designed to support rapid propagation and clean, soil-free growing. The set combines 36 small rockwool cubes with 30 sturdy 2-inch net cups, offering a ready-to-use foundation for cuttings, seed starting, and early-stage growth in soilless systems. The focus is on reliable moisture management, easy handling, and a compact footprint that fits small spaces or educational setups.

What you get

• 36 x 1.2-inch rockwool cubes engineered to hold moisture while allowing air access to developing roots
• 30 x 2-inch mesh cups with durable plastic for stable planting and simple transplanting

Why this setup can help your growth workflow

The rockwool material blends strong water absorption with good air permeability, creating a stable environment for seedlings and cuttings. The net cups enhance portability and make it easy to move plants between lights, shelves, or different growing areas without disturbing the roots.

Ideal uses and scenarios

• Seed starting in a soilless setup, indoors under grow lights or in a controlled space
• Cloning and propagating cuttings for faster establishment and transplant readiness
• Small patio gardens, classrooms, or hobbyist setups where compact, reusable components are valued

How to get started

Separate cubes with scissors as needed, then briefly soak each cube in a nutrient solution to balance EC and pH for your seeds. Once roots appear, transfer the cube and seedling into the net cup and begin growing soilless.

Safety and care tips: wear gloves when handling rockwool, and note that cups can be reused while the rockwool cubes are typically disposed after use. If you have questions about quality or fit for your setup, Halatool is available to help.
