24 hrs of light equals one more veg day every 4 days if comparing to 18/6. More lighted hours=more growth. My clones grow anywhere from 12-24inches during a 2 week veg period using foxfarm soil that I add vermiculite to and a 400 watt hps system with no co2 and good internode lengths.
highroller99 Reviewed by highroller99 on . Do You Use 18/6 or 24 hours of Light? So What Does Every One Use? 18/6 or 24 of light to Veg? Ive been reading some manuals that discuss both as an option. Ive always done 18/6 with my plants. I was wondering if there would be any added benefits to do 24 besides an increase in veg growth. I know with 18/6 the down side is you miss some veg growth because the plant can sometimes confuse the plant into thinking it should flower but doesn't. So any one have any down sides of 24? I know that 24 can cause hermies and more Males. Rating: 5
