Another interesting aspect of growing with LED's is pulsing them. Photosynthesis actually can occur at 100% with LED's being pulsed anywhere from 0-100 nanoseconds, longer pulses than this reduces photosynthetic effect. So by doing this we can save energy as pulsing the LED's for 100us on and 900us off would only have a 10% duty cycle so 1/10th of the total energy would be required compared to constant lighting. https://mywebspace.wisc.edu/tsharkey...ght%201995.pdf

physicsnole Reviewed by physicsnole on . LED growing- An instructional grow log trying this again. growing jack herer x bubbleberry in pure LED. these plants wont see any white light from seed to bud. tried posting pics once...so here we go again. questions or comments gladly answered. Dont think its been done quite like this before. ;) wish me luck! whiskeytango SnSstealth Rating: 5
