These Grodan Rockwool cubes are ideal for raising seedlings and cuttings. Once roots start to emerge through the cubes you will need to plant them on into larger Grodan Transplanting Cubes or some other medium.

Growing media is an essential part of any hydroponic growing system. Simply put, growing media is a soil substitute. There are many types of grow media available, each offering different advantages. These media are all inert, sterile substrates that have excellent aeration properties. Rockwool 1.5” cubes are ideal for starting seedlings / cuttings, and then can be transferred into 3″ or 4” cubes. Afterwards, growing cubes are either planted onto Rockwool slabs or into your hydroponic system.

Happy Newbie

I am fairly new to Hydroponics and growing veggies this way. I was thankful to be able to pickup these cubes (via eBay) from BubbleGrow. They were very quick to dispatch these to me and they arrived very quickly as well. Very happy with this service. The cubes look like good quality cubes too. Thank you!
