What size rockwool cubes for germination?

What size cubes and what brand, do you use?

should i use 1,5" or 1" cubes?

where can i buy them?

I think i will try the 2,5x2,5cm cubes, i get 150 cubes. With  the 3,6x3,6cm ones i only get 77 at the same price.

I ended up getting the 2,5x2,5cm grodan cubes.
They seem big enough. Also bought some biogrow and biobloom to experiment with.

Sounds like the same cubes I'm using, the ones that have a holes for the seeds on them ?

Mine do too.
Unfortunately my germination rate fell to about half. So only half the seeds germinated.
I then did as i have done before with germination soil and the germination rate was about 85% with the same seeds.

maybe i was unlucky.
