I got 16 seeds jumping up in seperate kegger cups 22 inches under a 600 watt metal halide conversion bulb running 24 hours a day.They aren't growin' fast. what gives? Any suggestions?
Tell us more details: - how old? - those cups have drainage holes? - how much you watering? - what kind of soil? - are you feeding? - distance to light? Post pics.
Maybe throw a fan on the bulb and lower the light about 6 inches. Also, seedlings generally grow slowly. -C
I think hes safe with a 600 w MH on leaving them at 2 ft. Seeds Grow slow man, wait til your ferting them, then they will shoot up.
