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

These are perfect. We have a Gardyn and didn't realize they are bigger then what we needed. But, they are ready to trim and once I soaked them in water they cut right apart with scissors. Make sure you wear gloves. Its melted, spun rock so the little pieces can be irritating to your skin. My plants flourish in them and for the price its great!

Because they weren't packaged with other things. They are 100% useable! Unlike some other vendors ship their product. I ordered some 1 inch by mistake. And they were shipped in a way that they were crushed. And if they have been crushed or squeezed. They are garbage, because the air get destroyed. So I would order 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.

I use these in my gardyn. They end up costing less than 5 cents each compared to Gardyn's $5!

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.

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!

These rock wool cubes work great. Would buy again. Highly recommend

Rockwool is not something that's all that complicated. In terms of it's water-holding ability and its abilities as a growth medium, its good. However, these plugs are the absolute worst of the different kinds I've tried over the years. They are beyond fragile; even touching them the wrong way (especially when they are saturated) will tear them in half. I understand that rockwool as a material is not super structurally sound, but being that these plugs heavily favor a certain grain direction, they tear super easily. I can't help but not recommend these plugs. I've used about 20 of them so far, and I've had to discard nearly half of them because they are so fragile, and break apart before I'm ready to use them. I know there are better options out there, so I will be going back to my previous preferred brands after this.
