Quite sad today.. day 49 and i'm starting to see some foxtailing for my first time ever. I had no more height after stretch =/ along with 85-95F temps. So today I lowered the light intensity hoping they'll calm their tits.
 
You have to try to lower plant temps bro… increase airflow through the plants. Lower the humidity to further increase transpiration rates onto of forced evaporation

Room temps are one element that effect plant temps but there are things you can do to help lower plant temps.

At those temps you may not get them as low as you want but can atleast improve them significantly.

There are many that run room temps from 80-90f on purpose.

Ideally when you increase transpiration you want to decrease nutrient concentration but you can’t really do that well in your situation. None the less give a bit more run off to help lower available nutrients after making some adjustments.

Do you have an IR temp gun and what are the plant temps. TKe reading from all o er the plants and gove a range if you can

You think I should lower the humidity with high temps?

I was thinking the opposite im so dumb lol although the humidity has been low.

I dont have a temp gun

Thank you for the tips Aqua (:

If its low already then leave it and increase airflow through the plants… you want to have good air flow to the underside of the leaves. Yeah it may slighty stress them but it will be less than the stress from the heat.

Oh yea no i blast them with wind I figured it would help with the heat. and the humidity has been around 40's.

edit: Ik the light is at like 16inches cus the stretch was way more then I intended. So it was at 90% intensity now its at like 60% after today.

Good plan… just make sure the wind is below the canopy and not over or blowing down on them

Pew pew

LeafST will be within 1-5 degree difference than ambient with LEDs afaik so far.

Ambient > 83f
leafST around 78-80 or so.

Does this apply to an oscillating fan? I have a fan below the canopy line and another above blowing air across the top of the canopy. Apart from windburn what is the detriment that can happen? You mentioned airflow being important on the underside of the leaves. I'm guessing this is because of the transpiration that happens here rather than the photosynthesis happening on the tops of the leaves? Would it be best to position the ceiling fan lower so that it sweeps across the top of the canopy rather than over it?

Aorflow iver the canopy is meaningless unless pushing heat from HID lights away… for some reason ppl are still doing this with LED. Your 100% bang on the leaves t from the underside and thats why it’s important to have the airflow under and through the canopy… to carry away the humidity that the leaves produce or you end up with unfavourable micro climates. I can expand on this later if you like but in off to a wedding rehearsal so will be a few hrs
 
Ok the humidity that’s important is the humidity directly at the underside of the leaf not the room. This is where the leaves exchange water vapour and gases.

You can have perfect humidity in your room and not ideal airflow. Literally say 55% room but when you measure it inside the plants it can be 80% or higher leading to issues caused by improper VPD. That can cause nutrient uptake issues and especially an environment thats favourable to mold, bacteria and fungi infections.

Many don’t realize how big this difference can be.

This is why its absolutely the most important to have airflow through and under the plants and use good pruning techniques.

Try turning your fans off and put a hygrometer inside them for 5 min. I bet you will be surprised how much it rises.

If you have dense plants and low airflow through you will be able to see this also. Thats why its a good idea to take random readings in the plants every so often to ensure this does not happen.

Airflow over top of the plants is really of no benefit unless using HID for the radiant heat they produce

One of the benefits I was told in regards to having a fan sweep across the top of the canopy is to mimic nature and to help strengthen branches. Is this not true?

If air movement below and through the canopy line is what is most important then it would seem that an oscillating fan set at the same level of the canopy so that it blows through the canopy would be best. Also have it come from opposing sides so that wind speed doesn't die half way through the canopy and only half of the canopy gets the gas exchange benefit?

On this last grow I had a stationary fan in the corner mounted to the ceiling blowing directly down to the floor. I'm assuming when the air hit the floor it spread across the floor and as air pressure built up it pushed the air up through the canopy. Would this be a better air circulation strategy?

It all depends on your fan setup. No 2 rooms are the same. I try to make a cyclone type action with exhaust at the top and intake at the bottom.

Mixing fans at or under canopy level.


Wind that moves the plants can aid in them developing a stronger structure… it doesn’t matter if the air is at the top or under as far as that result. But silica will do far more for that imo

Perfect. You've helped me figure out my fan placement! Thank You!
 
It's starting to look like normal stacking. This strain i've grown 2 times before and it only took around 50-60 days to finish flower...
but with the lights closer this time around they're about 2 times the size and still swelling
... i'm assuming it's gonna take twice as long now lol

You're complaining that you're getting bigger plants and more flower than last time? 🤔
 
The issue was that they threw out a new full set of pistols and they were already cannabalizing its self.

Barely has any green on a couple plants, so I don’t think it’ll finish up and I’ve never harvested any plants with white pistils still on it that was any good , have u? Genuinely asking

Thankfully I've never had to.

First time i grew Strawberry Cough, i took it 14 weeks and found 1 fan leaf with mildew so i cut it down with completely white pistils. Trichs were 90% cloudy, no bullshit it was very enjoyable smoke, but definitely couldve been better!

Did the white pistils fall off or na

Damn gotcha . Do u know by chance was it the light intensity or heat that was ur issue?

I chopped because i found mildew, pistils just turned during the dry.
 
Here’s pictures of the full plant can someone tell me what went wrong 😑 it kinda looked like this last time too. Seems to happen around day 30 . This time a lot of leaves went yellow then shriveled brown and fell off .
