Rockwool mini's ?

I was at the hydro store today and was picking up all my summer nutes and soil and I picked up a pack of rockwool starter cubs and I got home to see that there mini's not the ones I'm used to. But then again I could fit more in this way and am wondering are these ideal for clones and how well does the mini rockwool keep water for producing roots? I might like these better if they work the same as the bigger ones? Any help with this is great as I don't know it all

i use the little rockwool cubes for clones works a treat u dont water much at all the rockwool holds alot alot of water so its good for lazy people like me.

peace

are they the 1.5 inch ones ? thats what i use.

Yes there the mini 1.5 inch I'm used to using the 4inch I think because these are small . Wich is a good thing if it has no impact on the size of the plant later on. And I can't find one reason so sweet now I can take three times the cutings/clones!! I like it
