Description

Grodan Mini Blocks are made from specially engineered stone wool, a horticultural material renowned for its superb air-to-water ratio. This means your seedlings will receive the ideal balance of oxygen and moisture for optimal root development. With Grodan's advanced manufacturing process, each mini block is uniform in size and texture. This consistency is crucial for predictable and reliable results, ensuring that every seedling gets the same level of care and attention. These 2-inch mini blocks create an environment that promotes vigorous root growth. As your seedlings establish strong and healthy roots, they'll be better equipped to absorb nutrients and withstand transplant shock when it's time to move them to larger containers or your garden. Each order comes with THCity Gloves.

Package Dimensions: 12 x 4.2 x 3.4 inches

    • Nice product, no glove. :(
I have a few grows now under my belt, but I am always looking for new products to use that will increase efficiency. Primarily, these end up being electronics that just make the entire process easier. I went the "el cheapo" route before and ordered some rockwool "cubes" that were in a huge sheet, and just absolute trash. They would basically crumble in your hands. I am happy to tell you that this is not the case with this product. These little blocks are the perfect size for seedlings or cuttings. They also are firm to the touch. The plastic around them helps keep the shape so it is much harder to accidentally close the air pockets in the rockwool. I would give this product a 5 star rating, but the glove in the picture was not included. ... show more

    • Cadillac Blocks
I bought these to try my hand at some larger plants like peppers and tomatoes in deep water cultures. Although they are 2" squares they will not fill all the way to the bottom of a 3" net cup due to the cup's taper. I will pick up some 6" cups to use in 5 gallon buckets and see what happens. These blocks are nicely packaged and came with a set of gloves. Unlike the bulk sheets of 1.25" blocks, none arrive damaged. I look forward to using these and will follow up with a report on my success or failure. ... show more

I have been using this brand for a couple of years in my porch hydroponic garden. I have placed multiple orders which always come fast and in perfect condition. They will last longer then any plant you grow in your Hydroponic garden. I will continue to use them due to the great quality and fast shipping. Thanks! ... show more

    • Might be good
Not the best for soil, more for Hydro. That was why I gave it a three star rating. Neither good nor bad for me? Fair enough?

    • Probably the easiest way to start seeds.
I use these for both hydroponic and outdoor (Soil). I like them because you can see the roots coming out the bottom. Occasionally, you get a seed that looks good but barely any root grow. In soil, you would never know.

    • Good quality control and production
These are perfect for cloning... I suggest you soak and stabilize their pH... well made and well wrapped

    • Rockwool is rockwool. And this rockwool is nice n fat.
Big fat rockwool cubes. They are nice. Careful thpugh, they killed a lot of seedlings as they sprouted. The rockwool is hard and just sheared the plants off as they sprouted. When I started softening the area at the top of the hole the sprouts stopped getting sheared off.

    • Too big for 2inch net cups
Review Image by Michigan Reviewer
Warning : these are too big for the standard 2" netcups . If you have standard 2" netcups, you need to buy the smaller 1.5" rockwools Other than that, these are good standard rockwools and I received my pair of gloves unlike others
