Hydroponics Rockwool Cubes & Net Cups - 72 PCS 1.2 Inch Cubes With 56 PCS 2 Inch Cups For Soilless Growing

Hydroponic gardeners, this rockwool and net cup kit is exactly what you need for successful seed starting and plant cloning!

You get 72 rockwool cubes measuring 1.2x1.2x1.57 inches each, plus 56 durable 2-inch net cups - plenty for multiple growing projects.

The rockwool is made from high-quality basalt that's been melted and spun into fibers, then compressed into these perfect little cubes.

What makes rockwool so great for hydroponics is its amazing water retention and air permeability - it holds moisture perfectly while still allowing oxygen to reach the roots, which is crucial for healthy growth.

Each cube has a pre-made hole for easy seed insertion or cloning.

The net cups are made from sturdy plastic that won't deform or break, with slots around the sides that allow roots to grow freely into your nutrient solution.

The setup is simple: soak the cubes briefly in your nutrient solution, plant your seeds or cuttings, wait for germination and root development, then place the entire cube into a net cup in your hydroponic system.

The roots will grow through the net cup slots and into your nutrient reservoir.

A quick safety tip - wear gloves and maybe a mask when handling dry rockwool, as the fibers can be irritating.

This kit is perfect for Kratky method, deep water culture, or any hydroponic system where you need reliable seed starting media.

Whether you're growing herbs, vegetables, or flowers, this combination gives you the perfect foundation for healthy, vigorous plants without any soil mess.
