    They look great. A small dehumidifier is a must. You're going to need it for drying, big time.

    The more fan leaves you have the more humidity you will have which and the more fan leaves the less airflow there will be which is why i suggested defoliation. I have usually around 50-60% RH and as long as i have a fan and good airflow between colas i dont have any problems. As long as temps dont get below 60 F or 16C then it should be ok.

    Lovely looking plants. I’ve had similar issues in the past. I’d recommend upping the fan to max speed. A good dehumidifier will help lower rh too. I’ve just added mine and it’s reduced night time rh from high 80’s down to 40

    Lovely looking ladies, those things are really putting it on. The main problem I see is such a dense plant, that will always keep a higher humidity and even moreso within the plant. The buds being in such close contact will also generate a bit of heat around them and that too causes extra humidity along with all of the foliage transpiring. I've used dehumidifiers in the past to correct this issue. There are small tricks like the Damp-rid product for RVs and boats, but they are really only effective in smaller 2x2 tents. Larger size areas need the dehumidifier or if drawing air from a lung room, that room needs to have the humidity controlled and then the air intaking to your vent will also be at a good humidity.

    Thank you for the compliment SoOrbudgal, I am trying my best with the girls. Its just this high humidity has got me at the moment. I am quite worried about bud rot more than anything. I havent grown indoors for 15 years, and when growing outside I was just a plant them in the ground at let them grow grower pretty much for nearly 30 years. Even though I am really enjoying learning so much more about MJ, it can be quite daunting at times when its all new to you haha.
    I started seperating branches with straws and garden string, thanks to MeEasy for the idea, but unfortunately there are so many branches/buds that when I worked my way from the centre of the plant, by the time I got to the outer branches there was too much pressure on them. Snapped one branch unfortunately. Do you have any techniques/ideas that might work for me? Thank you

    I tried upping the exhaust fan speed to medium at lights out last night, didnt seem to work at all. So thinking of leaving it on high for the night to see if that makes any difference, would that cause any problems with the temperature? I have two fans going at the moment, one for between the light and plant, one blowing towards the top of the pot. Would adding more fans make a difference?
    Now with the defoliating Tersky haha. A few people know the trouble I had even thinking of touching a leaf at the 3 week mark of 12/12, the thought of doing it at this stage sends my anxiety straight through the roof lol. If I just stick to the ones not getting light towards the middle under the canopy, would that be a safe start?
    I apologise for all the questions, but I would really appreciate your advice. Thank you.

    Thanks for the replies girls and guys. It is becoming a bit of a struggle to keep the humidity down at night, temperature is sitting between 17C(62.6) and18C((64.4F) at night inside the tent. My anxiety levels have risen a fair bit in the last week. I have one oscilating blowing between the lights and plants that is positioned between the passive air intake holes( 4 x 200mm ). I also have another one at the other end under the exhaust fan blowing between the top of the pot and the bottom of the branches. I usually have the ducting heating set at 19C(66.2F), but kept that off with no difference in humidity. And turned the fan to medium instead of low at lights out, didnt change a thing. Have even tried keeping the window shut instead of open a bit in the room the tent is. During the day the humidity sits between 45-50%, occasionally down to 40%.

    F10werChyld I left the fan on Medium last night and didnt seem to make a difference unfortunately, so going to try leaving it on high tonight to see if that makes any difference. As for a dehumidifier, I was thinking about it even though I cant really afford it for two weeks due to just finishing setting up a cloning/propagation tent. But after reading Tersky comment about just exchanging humid air for more humid air, which makes sense to me, I think I will just have to keep trying other options as I cant afford one to do both areas at the moment.

    Oh my how beautiful almost to nice. Yes lower humidity it's so hard to make changes with the plant once they get to this stage a radical spreading of branches is almost needed. Some how spacers are needed in between those colas.

    I agree, upping fan speed will lower humidity a bit. Also adding clip on fans for air circulation and defoliating for airflow will help keep bud rot at bay. I disagree that a small dehumidifier will help tho as my experience has taught me that they dont lower RH but a few points at most. In order to control humidity with a dehumidifier you need a dehumidifier to handle the entire room the grow is located or the air exchange will just feed humid air back into the tent.

    Try upping the fan speed, but you may need to invest in a small dehumidifier. You'll get mold/bud rot problems if the humidity stays high throughout flowering.

    End of week 6 flowering..

    Hi guys and girls. Last day of week 6 since turning the lights to 12/12. Have had some issues with nutrient burn, temperature and humidity the last 2 to 3 weeks. Had to start supporting some buds today with bamboo stakes, they are starting to fill out nicely. I apologise for some of the pic's, the flash seems to be reflecting a bit more at the moment.
    Just wondering if anyone can give me some ideas on keeping the humidity down after lights out. The humidity was at 60% at lights on this morning. I usually keep the exhaust fan on low, it's a 3 speed controller on a ISO-Max 200. Would upping it to medium speed help?
