Germ/Planting question

So I germed a bagseed I found while waiting on my bean order, but haven't made it to the hydro store for the coco ill be growing in. How long can an already sprouted seed survive under germination conditions before being planted? It came from some killer stony smoke and I'd like to keep it alive. Thanks all

Not long.. it's going to need light in a day or so after sprouting or you'll end up with yellow leaves in the towel and recovery can be iffy from that. Got some perlite? That should work temporarily.

get a jiffy pot for 20c and put it in there otherwise it could run out of energy needed to complete germination. You can putit straight in the new medium when it arrives .
