You might be thinking of H202, You can dilute this alot to oxygenate water for seedlings, Believed to increase rate of germination although I haven't tried it.

Seeds pretty much germinate easily in most mediums as long as its moist, and around mid twenties Celcius (luke warm water).

From your pics you have the seeds diretly exposed to the light.... its probably better to have them covered in the medium, so stick them deeper inside the Cotton...(thats if that is cotton in the picture), but only just under the surface... you need light on them but not directly on them if you know what i mean.
Robsta Reviewed by Robsta on . germination problems ok- so i wanna try my green thumb out some. i got some seeds from a friend, he said it was from some mid's a few months ago (possibly a year or more but not much more). most of em are dark brown or grey, a few white ones (i know those are no good) - pics attached. first i threw them straight into some jiffy pots/cubes/whatever i picked up from the local garden store. 3 of the best seeds i could find per cube, did about 10 cubes (used 30 seeds of like 70 something). waited a week, Rating: 5
