temps on 1st grow

im 5 days in to my grow with 4 plants they all have 4 leaves on! there in a 2x2ft x 8 ft cupboard im only using a 125 cfl envirolite i have no fans yet but will! my temps are sitting around 75 deg and humidity about 45 percent is that ok? i open the door slightly when the lights are on thanks

sure, around 70% for early seedling development, 55-70% during veg and 30-40% during flower.
Get a fan.
Peace
