Rockwool Vs Coco Coir: What's The Difference?

[dan1989]

Hi everyone!

I'm growing in coco right now and am feeling pretty confident that I've gained a fair understanding of this hydroponic medium, which leads me onto rockwool slabs. I just read a thread where the guy is using them and it got me pretty interested. I'm definitely gonna order some and give them a try, I just wondered how you would compare working with the two. Any advice is massively appreciated like always.

From what I can find on cation exchange in rockwool it's sounding as if it's basically like coco and all hydroponics in terms of nutrient delivery. Little room for error :D
