Legigo1 Inch Rockwool Cubes Seed Starter Plugs for Hydroponics, RockWool Planting Grow Cubes for Hydroponic Tower Garden Soilless Cultivation Plants Germination Cutting Clone (4 Sheet, 200 Plugs)

Good stuff. Works great. Good value

Great value for the package. Rock wool comes packed nice and is a great medium for starting seeds. Germination goes as expected and great for root development. Would buy again and plan to use again next spring!

Good quality, they retain water well and 75% if my seeds have germinated and I have been able to plant them straight in to soil

Thank you so much

PROS:I cannot think of any.CONS:(See photos) 1 inch cubes are only half the length of other brands so they are much too short for 1 inch net cups.They are soft like cotton candy and flaky like biscuits and fall apart with handling. Plus, they excessively shed glass fibers when handling.Because you have to use 2 to make the size of one normal sized 1 inch pod and they fall apart, the price is no bargain.I AM an avid hydroponic grower and have experimented with several brands of rock wool for my lettuce, greens, cucumber, beans, tomato and seed starting systems. I use Kratky, ebb and flow, deep water, and hybrid systems.Although prices may differ I have found that all the rock wool cubes I ordered were basically of similar quality, allowing me to grow enough veggies to be able to share my bounty with many friends and neighbors and even strangers who appreciate fresh produce.That was until I ordered these. Some broke apart while taking them out of the box.Some flaked into pieces as I was removing them from the pre soak. There was way too much "rock dust" falling from the product.As I have already mentioned, each pod was 1/2 the size of any other 1 inch pod I have ever used, so I had to double them up to prevent light from entering my system.I do not recommend, so will be returning them and purchasing another brand.

My plants are growing well in these. I didn’t cut them apart soon enough but they cut easy when wet and it came with simple instructions to balance pH.

Warning, don't try to break these apart. Use scissors. They'll tear.

Works great
