I don't like HPS for young plants. It's too red. They'll tend to stretch more than if you had them under a light with a blue spectrum.
stinkyattic Reviewed by stinkyattic on . Too young for HPS? Help Please! Hello, This is my first time grow, only growing a few hoping one will be female. Very inexperienced but I have done my research. I would like your opinion on how I should treat my babies. They are 15 days old, they have been under CLFs they're whole lives, 24/0 light period. I have recently moved them under 600W HPS and they are on a 20/4 timer. I just made the move today, and am wondering if maybe they are too young for the HPS. Please help! Thanks!! Rating: 5
