4/20 : Seed soaked overnight (12 hours) and then planted into soil in Solo cup. Kept under fluorescent lights at 23C and 60%RH. Since determined the well water here is bad for germination. Having better luck with distilled water for the seed soak.
May 3: seeds soaking in distilled water for 48 hours, rolled in mycorrhizae and then planted.
May 17: still having problems. One germinated but the other four didn’t. I must have used the high sodium well water when preparing the soil, or these seeds were out of the fridge a bit too often. Will try again.
