Works like a charm
Planted five seeds directly in holes of presoaked cubes and placed into humidity tray under minimum amount of light. Within two days all five seeds had germinated, sprouted and already grown into robust healthy seedlings an and transferred seedlings in rockwool into soiled pots.Two months later... Unbelievably healthy plants.

The smaller cubes fit inside a 4 inch curve easily.
Everything works fine with these just wish they were a little deeper holes and I wouldn’t have to dig them out to put the other 1 inch cubes in.

Great!
I've been a grodan user for 15 years. They wouldn't come as fast so I tried these. Far superior product in every way. Takes in water much easier and there aren't any hard spots in them like I've been seeing in other cubes

Works well for hydroponic setups. Roots moved through within 3-4 days.
