Ive read that decreasing the temp differences between night and day decreases distance between “nodes, buds idr specifically” but they said it leads to more overall weed. Thicker buds, more weed/stem ratio?
I was wondering if anyone has tried this. I’m going to grow a kush plant for my first grow. Its going to be small and fat so i was thinking of keeping my temps around the same rather than letting them drop at night. Any oppinions?
A temp drop at night helps the plant in flower. Late in flower if u bring the temps down it helps the plant know its getting closer to time for harvest. I let mine drop around 64 at night. Dont know about the spacing but i believe it helps bring the trics out.

I read an interesting study/experiment a while back about how raising night temps a couple degress above day temps gives the tightest node spacing. Of course unless you have a really sweet climate setup this is not as easy as it sounds.

You can control node spacing with light intensity and light spectrum pretty easily. I have not noticed a big difference in temperature, but i never really looked either.

I’m not sure what you’re asking? I would suggest running light on timer regardless of what you’re looking for node spacing wise.
Well i ment with work, kids and life having timers would be necessary to control the lighting better
So, just did some refresher reading. Running temps higher at night will create the tightest spacing however it also slows growth the most. It was found keeping the smallest difference (a couple degrees) between day and night temps day being slighty warmer. Still gives the tight spacing and allows for good vertical growth too. Never actually tried to do this on purpose but with my temp controller and cooling/heating system in my space im pretty much maintaing a 2-3° diff anyway so…

Timer…a must!

Tents been running 50’sF at night and 80’sF day. been pulling killer plants out of it
Im not saying big shifts are not doable. I am only citing an actual experiment that produced these results. Plants of the same genetics all ran at diff ranges of day and night temps and this was the finding. Can you grow sweet flowers under big temp shifts sure. I dont think there would be alot of recomendations for a 30° swing though? Maybe your research into cold weather plants helped? Although autos (if thats what you choose from your huge grab bag? Lol) are crossed with ruderallis which is already cold tolerant so. Anyway, just swapping info. Enjoy!

Im not sure if its where I live (I pull filter outside air into the tent) but ive stopped trying to change anything and just run with it.
5 gal bucket with water in it for grow tent for humidity and nothing in flower tent.
Was going to heat tent and reservoirs" over mile high with snow outside" but it don’t seem to be necessary.

Ya, you should absolutely have your lights on a timer. I just wasn’t sure what the relation to node spacing was.

Wow 50’s at night. Thats not too cool?
Only problem so far is im starting some seeds and they seem to not really like it that cold even sitting on a heatmat.
Flowering tent plants don’t seem to care one bit going from 50F-85F
The 85F is from 1020w of led with the fan turned way down because it pulls 20F filtered air from outside into the tent. I just don’t have enough C02 in my house to grow big plants so I need outside air, you can really tell when airflows not there on the leaf structure of the plant.
