so i hear many strains will turn purple when in temps 50f and below but whats the limit right now its 18f where im at (JUST HAD A HUGE SNOW STORM) and my ladie is sitting on my window cill is it too cold for her?
Too cold by a window... Your plant should be around 20c @ lights off, minimum 18c... if your stems are turning purple, then its a good indication that the plant is too cold. Look for the underside of fan leafs for purple coloring too.
