Sativa seedlings tend to send down a long taproot in the first ten days, and starting them in shallow cups or jiffy pellets means they hit the bottom and stall before the first true leaves expand. A tall starter pot, even a cut down bottle, avoids the check in growth. I went with the transplant timing suggested on https://hazesativaseeds.com, which is to move up as soon as leaves reach the pot edge rather than waiting for roots to circle. Two transplants total is usually plenty for a full grow.
