They are slow growers obviously because they took a while to germinate and they and some have come up through the soil 4 days after the first. They are standing and going towards the lights. I have 6 cfls most of the biggest the 150 watt & 75 watt. Mylar on the walls, rapid test moisture tester, miracle grow soil, the temperature stays between 75-85 and 40-50% humidity. The seeds are top notch from a good bud. Is that a better description? Hoping that helps.....
