Cold weather and resin production/flowering times

Have been growing an OG kush clone for years and have noticed many slight differences depending on grow conditions:

1) If plant is subjected to colder temps(62 - 68F), resin production seems to increase, flowering times decrease but so does yield.

2) If plant is subjected to warmer temps(75 - 80F), resin production decreases, flowering times increase but yields increase also.

3) Some subtle differences noticed when using different nutes, additives etc. but environment seems most important when using same genetics.

Anyone else noticed similar environmental effects?

The other evening, i was trimming when I grew weary. I put the unfinished stuff in the refrigerator overnight and the resin exploded all over the buds. Itdrew the resin out of the buds and STINK, didn't it stink. From now on I will strip the plant of the fan leaves, and refridge it again, I was very impressed with the product...

Seasmoke, that is an interesting idea. I will definitely do an experiment next time I harvest. Did you partially trim it or was it like an entire branch with leaves and all?

Just take off the fan leaves, finish trimming the next day. My fridge still smells like bud LOL.

I need a big ass fridge!!! If the experiment works I might need to rent a meat locker '

I will have to drop the temps in my flowering chamber the last couple days before harvest , From 78 to say 50 and see how that works .

Another thing that happened that didn't before was they got a purple "hue" on them... not quite enough to call it purple bud, but it was still impressive to say the least...I know i'll do it again and refine it if I can. By the way it was White Widow I was working with. Next up is some WR.

Well , I keep my temps at 78 with lights on and 68 with lights off . I can drop the temps as low as I need too . My grow boxes have hvac so temp control is easy .

Give her hell. Good luck, I hope you get similiar results.

Nice fellas. Wont have a chance to try the fridge until harvest but I definitely notice higher resin when my temps are lower in flower........ but be careful too low a temp can lower your yield.

Here is a pic of my "cold temp" OG Kush

Damn pic didnt load..... check it out here www.cannagen.com - its the second pic in the rotating images(jar)

I just cut em down, stripped em, in the fridge they went....results comming...soonnnnnn....

Remove time from the equation and you have your answer.
IE dont change your flowering time

Bic - The flowering time increases yield but the goal is to also to keep the resin production high. Increasing the flowering time doesnt solve the problem.

Seasmoke - Any results??

Yes, same thing...these were the same plants I did it to the first time. WW that I took all the mature branches and left the stuff underneath and anything scraggly...they filled out nicely. This time I did half one day and another half the next so some of it had 2 days. It stayed fresh...i'm hoping for an additional 1/2 lb. Nice and crystally, sticky stuff. I took them before lights on so the thc would be at its highest, then after removing the fan leaves put them in a paper bag and placed that in the fridge. I didn't squash them though.

Okay. Ill be doing this experiment in about week. I will take high resolution pics and compare refridge buds to non-refridge buds. Should be interesting.

I don't think it's the cold for the last day that increases resin production, it's the darkness...Think of it like this, in nature the plant realizes it's the end of it's life cycle when it's darker longer...it realizes the cold is coming and it's about to die, so in a last ditch effort, it increases resin production in a last ditch effort to grab any available pollen...what I do, which works wonders, is on day 58 or 59 of a 60 day flower cycle, I turn the lights off and leave them off for 2-3 days before harvesting...when I pull them out to chop, they stick like a fly trap...I think what's happening when you're putting it in the fridge, is the lights go out when you shut the door and it's the darkness that's giving you the results you're seeing and not necessarily the cold....

OZUT - another intriguing hypothesis. The only way to know for sure is to do the experiment. I am going to chop down a branch put it in the fridge for 12 hours just like it was in the grow room. Then Ill chop another branch and keep it in darkness for 24 hours and compare.

Cant wait 2 c u guyz results, these rudalis auto strains or however u spell it is new and didnt they come from Russia/Syberia? I dont think WW is auto flowering tho...I want to try it on some auto-flowering strains Thx for the ideas.

I'll shed some light!

1) Resin output is not so much dependent on temperature as much as it is dependent on the humidity of the environment (as well as the genetics). The plant produces the resin for many reasons, but one of the main reasons is to prevent desiccation (drying-out). In an environment with a low humidity level, the same plant will produce more resin than if placed in an environment with higher humidity. This is why indoor plants are usually covered in crystals (since indoor humidity is relatively low) and outdoor plants can sometimes have very little resin, as it's subject to the high humidity levels from summer rains.
2) As far as temperature is concerned, we need to remember that temperature is simply the speed at which the atoms (and therefore molecules) are moving. This is why colder days slow growth rate (and output). Quick Example - If a plant needs to transport some fixed nitrogen from its roots to its new shoots (at the top of the plant), the speed at which the actual nitrogen atoms travel is slowed due to the lower temperature. So what takes 30min. on a 75degree day, could take over an hour on a 60degree day. Warmer temperatures also hold more water than colder temperatures, which explains why you noticed the lower resin with the higher temperatures.
3) I always use the same nutes, so I can't add to this one. But I would totally agree with what you said.

-Hope this helps
