DSM ferts and dry ice

I'm using the Dry Start Method today with some eleocharis 'belem' (dwarf hair grass).
My substrate is sand (Diamond Black).
I could spread individual pearls of Osmocote + into the substrate, but I'm not sure it that will work.
I have an aggressive slope that I hope to hold in place by growing a thick carpet for the sloped section of the tank.

Does anyone have a rough idea of how to use dry ferts to mist plants in the DSM?
I don't want to overdose them. I figured I should just mix a gallon of water to the parameters I usually shoot for, and use that to spray down the plants lightly once a day or two.

Also, has anyone on here heard of using dry ice to flood a DSM tank with CO2?
I'd be interested in trying it. Obviously you wouldn't want to freeze the tank, but a cube of dry ice becomes quite a lot of CO2.
If you let a cube evaporate (it should only take a few minutes) into a tank, and sealed it up with saran wrap, I'd think you'd have 50% or more CO2 concentration, which sounds pretty beneficial to me.

I think I'll be trying both Osmocote+ and spray ferts and see which seems to have a better response.
