really need help with watering!
I am trying to grow seedling transplants. I am using styrofoam blocks with holes in them; each hole holds a seed plug that is made of a soil less mix.
The light is about 4"-5" above the plants. I have the blocks directly on the heat mat. I am currently watering about twice a day (once in the morning, and once at night).
The middle of the soil plugs are moist, but the tops keep drying out. Is watering twice a day too fast?
If the rest of the soil is moist besides the top do I still need to water them, or will they be okay?
Basically I'd like to know if twice a day with watering when they're on the heat mat is overwatering. I don't use a humidity dome.
I know people recommend bottom-watering for seed starting, but whenever I try this the soil ends up too moist and the seeds either rot, or they germinate and I end up with this white fuzz on the stem of the seedling (the white fuzz isn't on the soil just the seedling that germinates).
