This was my first time and probably last time starting seeds in RR! I had to help most of my seeds get through the precut hole because the RR are to tough for them to move through. After helping as many as possible make it through it seems like only 5 are gonna make it out of 8! I gave the m all 3 days in the rapid rooters and the cotyledons were all bunched up in the RR's trying to reach the top. 1 day after helping most of them out they all began turning from the pale green color to the dark green healthy color! Only one made it through successfully on its own and its the healthiest of them all. Unless anyone can tell me away to plant seeds in them without having this problem, i truly dont recommend these to anyone but pro's!
