Rockwool Cubes 1 inch, Rock Wool Planting Cubes, Rock Wool for Hydroponic Growing, Perfect for Rooting, Cuttings, Cloning Plants, Seed Germination (4 Sheets, 200 Cubes Total)

Works great

I use these every year to germinate my seeds before transferring to the garden! 1 box has gotten me 2 years. High germination rate.

theSeed holes were missing or out of line.on the large padcauses the plants to grow off center

Works well for my seedlings, and hydroponic tower.

I have made 1,000 and 1,000 of clones with things like Root Riot and had great success. It's my first time with Rockwool and it works Great. Took a group of cuttings, mix 1/4 strength Lucus Forumla on top of the rockwool in a tray, poked a small hole, loaded my cuttings, put a dome on it under light and in 6-7 days I had roots. No rooting hormone was used. I left the rockwool pretty wet for the first 3 or 4 days and then drained it to stress the plants a bit.Talk about easy and cheap!

Wouldnt recommend

This particular rockwool falls apart easy. Delicate when using a blade to separate them. They work fine otherwise, retain liquids well, etc.Have had a fair number fall apart though, so there might be a higher quality version out there. I have used other rockwool before that was more dense that this particular batch. A decent mediocre quality. They definitely work though, 100% success cloning with them.

We purchased this for our home made aeroponic tower garden. This product worked great. We had great success in growing a variety of vegetables from seeds. The growth rate varied for each vegetable. The rockwool retained moisture but did not grow any mold. I would recommend.
