MI0512 1.5” Rockwool Starter Plugs for Hydroponics, Rockwool Grow Cubes, 1 Sheets of 28 Plugs (Small)

Order this rockwool all the time for our aeroponic tower gardens. These seem to be sturdier and do not melt away like some. Great value!

Arrived quickly. One cube was damaged, seller refunded 100%. Used remained cubes, 2 didn't even germinate the seeds. 100% satisfied with the remainder. Easy to use and fit snuggly in my 12 seedling nursery. VERY easily transplanted to soil. Will purchase again

it’s very shapeable and stays wet for the most part. it can break apart and melt if it stays in water. it’s a sensory nightmare for sensitive skin. the whole bag is filled with dust that looks like fiberglass dust and it will get everywhere.

Perfect. I tried 3 other brands. The 1st was too hard and wouldnt absorb water. The 2nd was too soft and fell apart. These really are just right. They get and stay wet not soaked and dry out about every other day.

1 1/2 " rockwool cubes for my gardening needs are just the thing for starting seeds and/or cuttings! You work with them wet to keep the dust in check especially if you are cutting them apart. They are perfect for the tiny squares starter tray I'm using at this time. These come in a slab, you, depending on your needs may prefer to use as a slab, I'm separating mine for my project and am totally happy to have these on hand. They perform well as any rockwool should, holds and nurtures your seedlings/cuttings until they are ready for next level advancement, onto another slab if you wish or set atop other substrate to continue growth, whatever your method, just take the cube and your offspring and move them right along. Great to use, inhibits other soil related problems, so yes, love them! Happy Growing!

Out of the whole pack I had about 1/3 of them damaged and unusable. The ones in good condition worked great. I'd use these again. I'm sure the delivery team is responsible for the damage for the most part. I'm giving 3 stars because of how easily they ripped up.

Excellent for seed starting in different hydroponics systems. Cut to fit with kitchen shears. Not a perfect fit for the Gardyn system, but close. Use a chopstick to press a hole in the center for seeds.

Complete waste of money, and time. These would not hold a seed, extremely dry and just a plume of probably dangerous dust when opening the package. They flake apart and have no use what so ever. I am really upset, cant even return them because the nearest location is 20 miles away, 20 miles back cost more in gas than the return.
