i had some seeds germin for almost 4 days now and 2 of em have a fuzz at the base of the mainroot and a green tinge toward the seed, common sense tells me this is natural but then again i saw the same thing wen my last crop of mush failed from FOREIGN BODIES!!!!! is the fuzz starter roots and the green its begining in color change to a stem or did something infect it, im askin to b sure cuz ive only ever seen a white mainroot popping out.
Just based on your descrip could be perfectly normal. Sounds like root hairs and possible normal coloring, but a pic is worth a thousand words. In any event, if the taproot has popped then germing is over, plant them asap. And if you have mold or not, your choices at this point are to throw them away (no point) or grow them out to see what happens (no downside). So just grow on and let us know what happens.
