Using a sliding schedule, that decreases light weekly, throughout flower can speed up harvest time, but less time growing/flowering and less lights does mean some loss of total yield. If you schedule it so that the light period only drops to the low of 10 hours the last week, overall yield shouldn’t suffer too much, not very significantly, but it also does depend on the various strains as well, some will react more or less favorably to such schedules, most likely noticing the biggest loss in yield in equatorial sativas, that are used to getting near 12 hours of light their entire life-cycle.
Got a New grow journal coming up as soon as I get the seeds planted. It germinated this afternoon and I am going to put it in starter soil tomorrow. “Grow Box SSH” will be started tomorrow. Gonna use the Golden Tree with my pH Perfect nutes. Later ya’ll Jerry
