@Scissor-Hanz: Yes, 3% peroxide. I tried to find a consensus on how much to use. It seems everyone has a different idea. I settled on 5:1 (5 parts water to 1 part 3% H2O2, like @legalcanada said) because I watched a YouTube video where they actually germinated for 7 or 8 days. Their control was straight water. Their test amounted to 5 parts water to 1 part 3% H2O2. Their test seeds were in that solution the entire time and the sprouts grew faster than they did in the controls subjects. Until day 6, when the control seeds caught up. On days 7 the control seeds passed the H2O2 subjects in sprout length.
Granted, they were not cannabis seeds. But the test left me thinking if they sprouted while soaking, they probably would get damaged by the peroxide. It did leave them very clean. No mold problems during extended stays in the towels. Before that, the older seeds I tried to germinate got moldy (white fuzzy mold) in only a day. I obviously needed to clean up my process and this seems to work. I'll continue to clean my seeds before germinating.
@legalcanada: No worries, bro. Its all good, informative, and related.
