AC or no AC

Question I have 12x8 grow room with eight bery white plants last ​​​​ grow I kept the lights on temperature around 76 to 77 and humidity around 55 to 60%, most of flowering and I had a lot of coloring and frosting up towards the end. My question is should I use my AC and try to mimic the weather outside and cool it down some the last couple weeks of flowering It is starting at 7th week now and I can get the temperatures down from 78 to 72 no problem with lights on and with lights off it can get down to around 66 67. Everywhere I've read as far as grow information from the normal websites says that berry white does great with humidity and temperatures and outdoors it thrives in warmer dry climate closer to 80°. So I figured indoors would be similar if you could make it that way. Just wondering if anyone's had any experience with this and mimicking the last couple weeks going into fall and if it helps with frosting up or not.
 
I say, The cooler the better during the last weeks of flower. Well, I don't mean down to 60F or anything like that, but cooler temps encourage trichome production. Your strain is 70% Indica, so it should love the cooler temps.
 
The top 3 things that effect quality/thc production; genetics, lights temp/humidity....like alltatup said you don’t want temps too low but if you can keep temp 65-75 and humidity below 50 you’ll notice a huge difference in how much frostier the buds get. Another thing I’ve done the last couple grows was raise my lights up in wk6 until they’re done. I read that in a article on here and it works. Raise those lights snd the frosty tops nearly doubles in in trichome production
 
Okay thank you I appreciate the advice my RH does raise when my lights are off not too much but enough to where I can probably turn the AC on to bring it down just a few degrees and take out some of the humidity. I just know that if you get cooler towards the end and raise your lights it's supposed to help with the density of the nugs. But I did not want to do a disservice and freezer out a week before they're done lol
 
bboyfromwayback Now that is some interesting info about less light in the last few weeks, and it makes sense regarding mimicking autumnal conditios!! I am going to try it on current grow. Thanks, bro!!!!
 
I tried the cheapo small dehumidifiers when I first began growing, but discovered they don't do shit, so I invested in a Frigidaire 32 pint one. It goes on sometime after I switch to 12/12 and stays on for the rest of flower. I live in a particularly humid region, and it's the only way to get through flower without any concerns about mildew or bud rot.
 
Raising the lights doesn’t help the buds thicken I increases trichome production. That’s why you want to wait until end of wk 6 or 7 when the buds aren’t growing much more and are really just maturing. It’s pretty much the same concept as a couple days of darkness before harvest. Wish I’d saved the article. Last grow at the end of wk6 I raised the lights to 24” above the canopy, I had some colas as close as 11”. Next day the tops were frosty as hell so next grow I tried it with same results.
 
Hi there, Sounds like you have a really nice grow room complete with humidity and temp control. I'm working towards the same but am having trouble working out the A/C installation. The obvious choice is to punch a window opening in my exterior wall and use a window mount A/C unit. Is that the approach you used? My dehumidifier was a gawd-send during the humid summer, but they produce heated output air hence the need for A/C.

That’s really interesting!! Shit, something new to learn every day. I raised my LEDS by 4 inches about a week ago. I was at the max height of my pulleys, and That was the distance between the pulley carabiner and the carabiner on the light assembly. 3 of the 4 strains have gone crazy frosty since then, actually allowing me to tell the difference between a couple of strains that I wasn’t entirely sure on.
Thanks Bboy!
 
Thanks to GWE! I only passed along the info lol.....crazy though huh? I was hoping somebody else would try it with good results to help confirm the results. I’ve done it the last 2 grows and I wait until the leaves start dying off so I know the plants done growing and both times the trichomes really came out. Almost double frostiness overnight. Another tid bit I’ve tried is from week 6 on all they get is ph’d water with molasses, no measured amount but probably close to 2 tbsp a gallon if I had to guess. But I been giving them molasses every watering from wk6 till harvest and the buds are cured within a week. I’ve done this with several strains, same results. Within a week there’s no fresh smell when you open the jars and the smoke is smooth.

Thanks for the article, that’s a good read! I’ve been raising the lights after week 6 but not the way they say to do it. I’ve been going from right above the canopy to one big jump up in height. Next grow I’m going to do it this way and see how that goes 👍🏻
 
You just gave me an experiment to conduct 😂
I only needed another inch or 2 of height, yet raised all 4 LEDs by 4 inches, because I would have to modify the hanging assemblies in order to do anything different.
I’m gonna modify 2 of them today so I can lower them back to the height my girls will accept 😂 28-30 inches... frickin cheap LEDS!
Then I’ll have one screen at optimal and one with higher lights, so we can see if the difference is as obvious as you’re thinking it is. I ♥️Science.
 
Forgot to ask- end of week six? I was planning on giving really light nutes till the end of week 7. Half strength basically half the time. Used the molasses on my outdoor, but have nothing to compare it to.
 
That’s just something I started doing and it definitely works at getting all the chemicals out bc by the time they’re ready just about all the leaves are spent and dead. However I read a article yesterday by Nebula where she said to keep leaves green as long as possible bc it makes your buds prettier instead of having brown leaves in your bud. I have to agree with her on that one. Buds aren’t as pretty but ready to smoke sooner
 
Raising the lights a little bit at a time seems to be helping out aww the fall colors are here
