Features

  • Premium MaterialOur rockwool grow cubes are very effective hydroponics substrates, made of high-quality basalt and chalk, being melted at high temperature then centrifuged at high speed to spraye into 0.005mm fibers and pressed into blocks.
  • Benefits of Soilless CultivationRockwool cubes are superior to other typical hydroponic supplies, with up to 96% porosity and 91% water. Even distribution of nutrients, does not absorb nutrients from the crop, encouraging rapid root growth and higher yield so that suitable for mechanized seedling.
  • Easy to TransplantRockwool cubes can be cultivated either whole or individually. Since the rock wool is transversely textured, we recommend wearing gloves and cutting with scissors instead of tearing by hand. Rockwool grow cubes keep the seeds long enough to establish a root system because of their high water absorption, so that the survival rate of transplanting is high.
  • Wide ApplicationThese rockwool starter plugs have pure composition and handy planting hole, widely used in hydroponic, seed starting, rooting, plant propagation, cloning systems and so on. Low environmental impact, easy to handle compared to other substrates, great for planting enthusiasts and commercial growers.
  • Package Included1 sheets of 50 cubes, 50 cubes in total. Simply soak the rockwool cube briefly(10 sec) in acidic nutrient solution and adjust its pH value around to 5.5. Don't squeeze it!

  • Conveniently sealed package, same number of baskets as cubes
Size: 50 Plugs+50 basket
These small rockwool cubes are ideal for quickly cloning plants that you will repot, or starting seeds that you will replant as seedlings. It is advisable to wear gloves and possibly a mask when handling rock wool, especially if you will be tearing the cubes apart instead of cutting them with scissors. I like that these small cubes come with the right amount of baskets to use them all at once. Because the whole cube will get re-planted with the plant to avoid damaging the growing roots, you can reuse the plastic cups, but not the cubes. This set does come with some instructions, an improvement over many others, making it ideal for a beginner. You can get started with any container that holds water… These are small enough to fit in a plastic storage box, something to raise the acidity of the water such as lemon juice, and hydroponic plant nutrients that you can find pretty easily in dry pellet form as replacements for the nutrients that come with a starter hydroponic system. This can be used indoors under a grow light, or outside. This would be a good gift for anyone starting out with hydroponics, any parent who wants to teach their kids about cloning plants or growing seeds, or anyone with a small patio garden. It does not come with a container to put them in, so that will also be needed, as well as the hydroponic plant nutrients. ... show more

  • Great Value for 50 pack
Size: 50 Plugs+50 basket
The Jowlawn 1" Rockwool Cubes have been an absolute game-changer for my hydroponics setup. With this 50-pack, it's not just a great value; it's an essential investment for any hydroponics enthusiast. These cubes are perfect for rooting, cloning plants, and starting seeds. They provide excellent support and a stable environment for healthy root development. The additional 50-pack of 1.5 inch Net Pots that comes with them is incredibly convenient. These have become my go-to choice for hydroponic growing, and I couldn't be happier with the results. If you're looking for quality hydroponic supplies, this combo is a fantastic choice. ... show more

  • Super compact
Size: 200 Plugs
These take up so little storage space which is super convenient. I will try them out as soon as the weather warrants.

  • Works great with my aquaponics system
Size: 50 Plugs+50 basket
I got these to use with my aquaponics system and so far they work great. We're winding down the season but I was able to grow a nice crop of lettuce.

  • Only 1" tall, not the traditional 2"
Size: 200 Plugs
I've been using Grodan rockwool in plug trays but thought I would see if these less expensive ones would work. They won't. Cubes I've been using are 2" tall, 1" wide in both dimensions on the top. These cubes are only an inch tall so they would not be anywhere near the water in my plug trays. They were cheap enough I'm not going to bother returning them and lesson learned, back to the quality stuff I've used in the past. ... show more

  • good growing medium
Size: 200 Plugs
For hydroponics or rooting cuttings applications, these little rockwool cubes are easy to use and convenient. I don't have to worry too much about the cuttings drying out, due to the moisture retention of the cubes.

  • Good quality rock wool
Size: 50 Plugs+50 basket
This is my third purchase of rockwool. The first time the squares were individually wrapped that worked great. The second time, the squares were very soft and also had to be cut apart. It got too soggy and the plants sprouted, but didn’t thrive. This rockwool is more firm, which I like, and it can easily be cut apart with scissors. The enclosed plastic baskets for holding the rock wool were deeper than I imagined for 1” squares, but it actually worked pretty well to cut them apart and drop them into the baskets. It made me think that I was using too big a piece of rock wool in my baskets in the past. I use this Rockwool in a hydroponic garden in which I grow herbs and lettuce. I’ve had very good luck sprouting seeds in Rockwool, and would recommend it to others, but I still wish I could find the individually wrapped squares, as they worked so well, and didn’t involve releasing fibers into the air when I cut it. I rate this rockwool four stars. ... show more
