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

I use this with gardyn cubes and work amazing

I purchased these to use in my Gardyn and they fit and work perfectly.

The cubes were of good quality but a bit large for my tower garden. The 1" would have been better. They still worked with a bit of squishing.

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!

Got my rockwool in a paper envelope. Looks like they were smashed . Opened package and all off the cubes are falling apart. Very poor quality.

Great for starting seeds. Hydroponics or media easy transfer of started seeds.

For context, I use the Rockwool in my seed starting trays for my hydroponic towers. It's typically pretty simple, wet the rock wool let it soak, and place it in the individualized trays. Then from there place seeds etc. This Rockwool is very disappointing it disendergeated upon me applying water this has never happened I only purchased it because I thought I was getting a deal. I won't make that mistake again.

I grow freckles romaine all year long hydroponically and this rock wool works for me. Just place your seeds into the little hole and add water keeping the cubes wet until you can transfer them to baskets. Good to grow!
