That's what healthy Babies SHOULD look like..., perfect color, VERY healthy. (Where did YOU find the Pics??? LOL ) Your on the right track. The Peat & Coir stuff is anti-microbial, and is used for a filler. But no problem with small in-door grows. The soil, pre-mix is some good shit. As of 2 months ago, the Dirt Doctor started a new procedure. Your first pic is a good example. See all the new roots, going in circles? When transplanted to bigger pots, these will "eventually" grow outward, especially if you force them to by just watering 2 inches further out to make the new roots seek the moisture. But also, the Dirt Dr., on bigger root balls, He takes a razor knife, cuts from top to bottom, the outter roots, about 4 to 6 cuts. Then loosen's the roots, get them sticking out, then transplant. This causes the new growth to spread out 70% faster than just moving from one pot to the next. On the size you have, I soak in warm water/seaweed for an hour, then comb out the new roots, then transplant. Or, use a bigger container to start with, negating all the additional work. Great Job, so far.
