@DavidLMO I am soaking both seed and media in 1 tbsp peroxide to 2 cups of RO water. Any additional misting or watering is with the same solution. The pictured batch is planted in Hoffman's soil. They have been on heat mat and T5 lights since planting. Lights about 12hours/day. Not on a timer, so that is not exact. Subsequent planting seeds have been in Jiffy pellets and Root Riot cubes(expensive!). Both soaked in H2O2 solution. I am keeping the seeds covered until they sprout to get that little mini greenhouse effect. Hope this makes sense. What media are you using? I am thinking it is a combination of things at work here and think that along with the peroxide, the constant heat is good also. Would be interested to compare differences here since we have essentially the same seed from Brad's.
