This is my first time growing vegetables. I planted my buttercrunch in starter cups indoors (under a plant light 8 hours per day) with the intention of moving them to my outdoor garden once they are a little more developed. However, they just kept becoming ....leggy? I have been waiting for them to start looking more like a HEAD of lettuce rather than a bag of spinach but alas it just keeps getting worse.

If it helps my zone is 8a
