I do somewhere in between the two. I get a slight root mat, but not real tightly twined, and about an inch or so of green grass in patches. I've also tried both sprouts and full on fodder, and mine seem to greatly prefer this in-between stage. I feed it out I think at about 5 days. I was able to feed it out at 4, but with the colder weather my growing area is cooler and sprouting is slowed down somewhat.
