Day and night temps

[theother]

Been playing around with this for awhile and it seems to me I am consistently getting a larger yield and generally higher quality when my day and night temps are very nearly the same. I do still cool it down in late flower but that's it.

Anyone else noticed anything similar?

I've read that keeping your day/night temps the same will result in much less stretch, henceforth tighter internodes/better stacking. I'm about to flip a gg4 room (very stretchy), and will be keeping temps @ 80 throughout 4-5 weeks of bloom, hoping that basic science prevails.

I'm not positive I would count on it to keep stretch down exactly, IME so far everything grows better and faster (including vegetative growth). It may well be that my intermodal spacing is tighter, but it's not dramatic. What is dramatic is the growth rate both in stretch and in flower. I find that the same strains flipped at the same time, the plants with the same day and night end up on average 6" taller than a room with a 5 degree drop at night. I don't have an exact average for yield increase but it is dramatic.

An interesting thing to me is the increase in nutrient uptake. The plants are straight up hungrier. A year ago when I tried it for the first time I ended up under feeding. I have ultimately raised my ec about 30% and rarely clear water. In a sealed enriched completely even environment it seems the nutes end up being the limiting factor if your not careful.

These plants are amazing, I didn't think I had that much more to learn lol, but that 5 degree change definitely taught me some stuff.
