Thanks! No pride until I cure and sample them lol. Growing is only 30% of my battle.I'm aiming to finish them July 3rd. When I looked up how many hours of light they would get it was close to what Malawi Africa would get. My more complicated explanation is below.I have been dropping the light schedule progressively since week six for several reasons.
-lowering the light schedule allows the plants to finish earlier
-it causes more sativa like pheno type expressions to occur
It has been said that lowering the schedule from anything under 12 significantly reduces yield but I disagree. Plants have a daily light integral of how much light with and without c02 they can utilize before it becomes too much. Cannabis only requires 43-48mol²/day of light and with my lights at 12/12 they would supposedly receive 70mol²/day whereas with a 9.5/14.5 schedule I would have 56mol²/day still being above the requirements of cannabis. I could actually go down to 8/16 and be right at 47mol²/day keeping me in range.
With that being said, I believe the reason for loss inn yield was due to the inefficiency of HPS/Blurples not being able provide adequate PPFD to aid in development when anything below 12/12 occurred. However DJ Short has stated that 12/12 is a farce for the most part and that sativas can really express themselves below 12 hoursIn nature it would be called senescence and, for me at least, it is achieved by lowering the feed progressively over the last few weeks. I'm only watering at 200ppm of feed and 200ppm from tap water and by the last 3 days I'll be watering with plain water. Essentially it's a flush or leaching, I consider it leaching or fading rather than flushing, and by doing this it removes excess fertilizer and let's the plant pull nutrition from its leaves hence the yellowing.
I've been testing bud on the plant that had 1000ppms and buds that had 500 ppms. The bud that had less feed smokes cleaner, smoother, and burns better with less crackling.
