Wasn’t sure what exactly I wanted to grow back then, but we found that we used the lettuce the most for a weekly chicken Caesar salad that was better quality than the bagged lettuce from the supermarket. We decided to replant the Gardyn Studio with all lettuce seeds from Johnny’s Seeds website and purchased these rockwool pods as they fit the pods perfectly. The product is easy to tear and fit into the pods, however the clear plastic wrap packaging around the 2 sheets of rockwool is just a one time use, so if you don’t use all of it you need to put the extras in something else. The studio model only holds 16 pods, so 98 was more than we needed and the left over rockwool I stored in ziplock bags for the next replant in a few months. In the Gardyn all the replanted pods with this rockwool have sprouted, so the product has met my intended needs and I would recommend them for any other Gardyn owner looking to plant with their own better quality seeds. Review: Easy to use - I had never used rockwool before, but it was the material used by my hydroponic garden system the Gardyn. This is the size that fits the cups. The edging where the cubes tear are a little wider than the cup, but I fit it in when its wet, then add my seed and moisten. It has a hole in the center, so you won't need an awl either. Good price, good value. Just what I was looking for. ## Features - 98 Rockwool Cubes for Hydroponics – Includes two half-sheets of 49 plugs (98 total) for easy handling and efficient shipping. - 1.5" Rock Wool Planting Cubes – Perfect size for starting seeds and rooting cuttings in hydroponic growing systems or propagation trays. - Clean and Ready to Use – Made from natural basalt rock and designed to support even water distribution for reliable seed starting and root development. - Ideal for Hydroponics & Soilless Growing – Use with DWC, NFT, ebb and flow, or any hydroponic system for consistent, clean root zone management. - Fits Standard Trays – Each sheet fits into standard 10x20 propagation trays.
