I bought a couple 25 trays of root riot cubes. Before I used coco pellets or rockwool. These riot cubes feel just like a sponge. They have really small holes and even if you try to enlarge them they go back together. I pushed 10 beans down in them and it just seems way to tight. Can they sprout ok under this condition ? I place them fairly shallow so they don't have to fight too hard to escape. Thanks for any help.
