Hiya This is kinda embarassing but im not having much success starting seeds in RW cubes. Pre soaked cube in ph'd water 5.5, started seeds in paper towels, when they popped I put them in the hole in cube maybe 6/7mm deep, put cube in humidity dome and left on windowsill. I can see the seed in the hole, its been 3 days now and it doesnt appear to be moving upwards. Any ideas what im doing wrong? Should the cube be under lights? More patience? Thanks!
