Best of luck man. Sending good vibes to you and those beans ;) The humidity domes should help the medium stay moist, but of course make sure that top layer doesn't dry out, while making sure to not over-saturate.
My super high tech method of germination is also simply planting the seeds into soil (after a quick scuff in my super high tech "scuffbox") and I have excellent results - in fact I planted an 11-pack of Goji's on Sunday night, and have 10 healthy sprouts as of last night (so, basically 48 hours, but 36 hours since the first one broke ground), with the last one about to break the soil right now. But, I do believe that my super high tech germination method has a higher success rate with a tad bit of warmth. If you don't have enough seedling heat mats for all of those, just make sure they are in a room that is slightly above average room temp, ~72-75F to improve your chances.
Curious to see how many of these pop for you - we're all going to look like fools if you get > 90% - lol. If so, at least you'll have a bunch of seedlings to choose from eh?
What strains?
