Light on temps pushing 90F

[2Bad]

So I had temp and humidity to the T but I didn’t have air circulation.. should I have my exhaust on still?

I dried whole plant then trimmed. It seemed about right dryness, obviously tried it right away and big difference after a few month of curing, but I did mess something up

Personally I put in a closet with the door cracked and have a small fan oscillating outside of it giving indirect air . Many ways to do it I'm sure.

I run into heat issues in summer, so I use both an exhaust and intake fan. 5x5 tent with a 6" duct booster fan exhausting into another room, and a 8" duct booster fan drawing air from the other room. I went with the 8" on the intake for more cfm because I'm pulling air through a furnace filter. Even if you don't have a separate lung room to utilize, if your temps are that high, you should at least get the air moving in & out of your tent, and into whatever room the tent is in.
Lower the light % for cooler temps. Find your light chart, or check for a youtube par test for your light. I could get 900 at 60% at 6" with a 680 watt. That would be enough for flower.

My post wasn't directed at you in particular. Moreso most all newbs don't understand that the dry and cure portion of the grow is just as important as the cultivation part.

hey everyone I have Super lemon haze and gorilla glue I checked on today and noticed temps just over 90 degrees. 4th week of flower and I would assume it’s been this hot for a week or two since I put my sf7000 on 75% power. Any signs of stress you guys see??

what ppfd and or dli are you running here? we're hitting 31 constantly in peak summer if no ac running, the ones that don't respond well to my climate/parameters get culled quick. can see no visible stress on your plants no. it's a beautiful cultivar you got growing there.

*have found the majority or plants to display heats stress at temp of 92-93f and above.

So I don’t have any light meters maybe I should grab one, I definitely got it below 80 now, fan up a little and light down a touch. Thanks!

fiance has a flagship galaxy which takes dli readings accurately when compared to manufacturers chart and iphone xs, iphone 12 using the Photone app. we got fan oscillating over canopy and another running down the hid reflectors and extracted through ceiling vent

I've got a quantum light meter and its fairly expensive. Now before you run out and buy one, do you have a smart phone? If so, there's smart phone apps for free that can be pretty accurate depending on your phone's hardware capabilities. A free app like PPFD Meter would save you a bit of cash and would be good enough to keep you in the ballpark with your light output.

Yep I use the Photone app, I don’t trust them 100% they are free after all, but I use it to get in the range I want to be and adjust the light to the response of the plants from that point

Didn‘t read it all but room temps really dont matter all that much… its plant temps and that had a bunch of influences. I wont go over them all but if the plants look good then your probably fine.

running a slightly higher range of VPD will increase transpiration and transpiration causes evaporative cooling, wind will increase cooling further by forced evaporatio. So room temos maybe high and plant temps can still be ideal. Of course there are limits to this.

if your carbon filter was exposed to over 60% humidity it can cause the carbon to swell and restrict airflow. This is where quality of the filtet matters. But all will restrict airflow a little to start with.

If you want to take all the guess work out of it then it will cost ya the grand price of about $25 for an IR temp gun to measure leaf and plant temps.

Hey guys I have one plants that’s getting some discoloration, other 3 seem fine for now.. any ideas? I’ll get ppm readings in a bit, 900 or so going in every feeding

Sooo runoff showing more than 1000 ppm on 3 of 4 plants, 4th plant showing 500.

Putting in around 1000 ppm so some kind of lock out I’m assuming…

Ph was 6-6.5 in runoffs
