Need tips for RAPID ROOTER seed germination

Have you used Rapid Rooter to germ seeds?
How often did you water it? Seems that dry out fast, way faster than rockwool.

I just got some today from Amazon, haven't even opened em up. I got em for starting seeds too.

insert bean and water once or twice a day

I like rapid rooters a lot. One thing I do even though they are already damp I soak them in water for a few minutes before I insert seed or clone. Soak them for at least a few minutes, gently squeeze some of the water out and I don't have to water at all the first week or so.

if you use a rapid rooter tray, the tray will hug the rooter cubes and reduce the surface area exposed, reducing amount of water lost due to evaporation
