I bought a case over a year ago. There are two types...1 type comes with a 'hormone' for rooting the other is 'hormone' free. The hormone free type claim to be organic,and the best I can figure is they are made of a peat powder and some kind of cellulose??...
They powder if smashed and break down fairly quickly...
Rooting is always 100%....the way they hold tight around the cutting as you insert it into the cube prevents destructive insects from reaching the developing roots...as well as transferring moisture at a constant rate to all parts of the inserted cutting. Rooting is usually accomplished in 7 to 10 days if your conditions are dialed in.
