I'm getting ready to start up 6 under lites in a 5'X4' space. I can't hack paying to operate HID anymore plus the heat is unaccepttable. I need to know how many LEDs for this space, and what rating, and brand. Thanks so much.
Do the plants detect the length of time in the dark like they do hours of light? For instance, if the plant is running a 18/6 light cycle and it is left in the dark for 12 hours would that shock it into starting to flower?
This will be my third time out. I've been running a 24/7 light cycle, but with 400w metal halide the electric bill is eating me alive. Starting fresh I want to go with a 18/6 light cycle, but not sure how much time will be added to the vegetative phase of growth. Can someone add insight?
