night-time film exposures can be shot in as little as 15 seconds (moonlight, clear night) or 20-30 minutes (just starlight) that's not a lot of light, the light at night renders few colors and contains little "usefull" light for plant growth. This perhaps explains the "effect" of night-light has on things; There are a few flowers that only bloom at night, but that is regulated by hormones, not the light directly.
4x5 Reviewed by 4x5 on . An experiment in regards to stray light and light cycle interuption... I am going to be conducting a little experiment over the next few months. The basis for my experiment will be how much light is needed in order to interupt, stress and revert the flowering plants back into veg growth. The reason I am doing this is because I always see posters asking about absolute darkness and flowering. i have also seen it stated in various books that grow area MUST be kept completely dark. Is COMPLETE darkness needed or is it just another optimization factor that is Rating: 5
