Alright so is this color change brought on by a mere reduction to “x” degrees at night, or can it simply be brought on by a night fluctuation of “y” as it relates to day temp. I am running 83-87 day temps depending on what side of the house sun is on and around 73 at night. Would this work or would I need it colder. Not the end of the world either way but I am growing three purple strains, would be a bonus to be able to bring that out.
Also, what timeframe is relevant…only last couple weeks of flowering, right?
We have had three days with high of 50 and lows mid 40’s. Tent temp is 67 lights on and prob upper 40’s at night. This is what I got today out of one of my Gelato’s. Seemed like overnight but took a full 3 days to color up. Beautiful colors and a head of cauliflower.
