I bought 10 ww seeds off of the net. germinated with paper towel method. all of the seeds germinated. planted them in my ebb and flow. put them in the cubes. put them down in the perlite. and only one of the seeds came up. Only one. It's about an inch tall and is looking perfectly healthy. I decided to pull up one of the grow cubes and check the seed. I pulled it out and the seed didn't look any different than it did when I took it out of the paper towel. any advice?
