Tues Feb 16th:
Haven't needed to water seedlings since planting; soil is still moist but not too wet.
Some stretching in White Rhino, Special Queen, and Blueberry (non-fem) seedlings, most likely b/c they were left on heat mat too long (light is a good distance and stretching seems to have stopped after taking the seedlings off the mat).
Using fan to strengthen stems - probably won't be re-planting them deeper until it's time to move to bigger pots since the stretch isn't too bad.
Finally removed helmet head seed from Blueberry (fem) seedling, but one cotyledon is still small and pale, and overall growth is slower than the other seedlings.
