Last year I crossed several OT Tetra x OT Tetra without any luck. But my few crosses with Flugelhorn Tetra Collection I purchased from The Lily Garden seems like I am getting high germination. I tested a cross planting 10 seeds, placed in the west window, no special heat. Out of the 10 seeds 9 has so far germinated. Planted in 2-1-2011
