The plant gets water when the soil dries. This could take 2-3 hours after the lights turn on or when the plants look thirsty. I did have an overwatering problem on day 11 after remoistening the outer edges of the pot because it was dry. She began to curl and droop but shes recovered well on day 12. I’ll let the soil dry out for the next 2-3 days before watering. Heading into week 3.
