A time lapse video is created by taking pictures at regular intervals (here the camera is set for every 5 minutes) and rendering them together as a video. - The lights are on for the entire duration of the shoot (usually lasts a few weeks). For vegetative growth (meaning just leaf/stem growth, not flowers), I have never noticed any negative effect of constant light. - Plant: Anthurium veitchii ~ ~ #houseplantjournal #hpjtimelapse #planttimelapsevideo #leaftimelapse #houseplants #anthurium #anthuriumveitchii
