@Growgirl1114,
Hey there✌️
I keep my seedlings @ 22-25°C and 70% RH
Veg. Cycle, depending a bit on the Strain, 20-26°C and a average humidity of 50-60%.
Bloom Cycle, also 20-26°C and a RH of 40-45%.
Keep the difference between day and night temp as small as possible!
Hope this helps a bit, cheerz..✌️
O.
