Look into controllers . Life has never been so easy since getting them
No I but I heard that’s a pretty sweet system . I use inkbird controllers . They’re were like 60$ for the pair . One for temp and one for humidity. If you go the ink bird route get the wifi one . I didn’t and regret it . Didn’t realize they even had it .I wanted to buy an AC Infinity T6, instead of the S6 because it has a controller, but I've spent so much money I was worried about spending more. Probably should have gone with the controller because it sounds like it would make a difference. I guess I can still buy one though.
Do you have the AC Infinity controller?
Nice, thanks for the reply! If I understand correctly, I need to crank up the humidity and then increase the power to my lights. If you and others are able to grow successfully with high temperatures, then I should be able to as well. I have a humidifier in my tent as of today, and am trying to figure out how to raise the humidity without lowering the intake fan speed too much. Gotta find that balance between fresh air coming in and not too much humid air leaving.I'm currently in week 7 of flower with a Red Dragon in a 3x3 with a TSW2000 atm and with tent closed Temps are 82F - 88F with RH 45% - 65% on avg. Light is 300 watts on 100% 16" from tops.
I have an 18" Turbo-Aire high velocity floor fan running 24/7 for circulation, pushes serious CFM of 11,000 @ 20 ft, im running on lowest setting so prob 3500 CFM.
An 4 inch inline cycling fresh air for 15 min every hour. This brings RH down to 25% and Temps down to 80F at the end of that 15 min, take about 30 min to get back up.
RH is higher in morning on watering, which I do at light on, and lower in afternoon.
No issues at all with heat or light stress.... dialing in my nutes feeding I'm still working on lol.
Yeah, I have the t6 and it works well.I wanted to buy an AC Infinity T6, instead of the S6 because it has a controller, but I've spent so much money I was worried about spending more.

It looks like you have the bottom vents closed. Open them up or more of them so you get more airflow. Filter them of course.Here's an update with photos!
I'm having trouble figuring out if the oldest plant (Canuk Cookies) in the back, is suffering from heat stress, over/under watering, nutrient deficiency/nutrient toxicity, etc.
The Canuk Cookies plant perked up after a small watering yesterday. I lost my first grow due to mold (over watering + temps too high, is my guess) so I'm trying to figure out how to water plants properly. I'm now waiting until the top soil is totally dry up to my second knuckle before watering. Because of the heat, maybe I'm waiting too long though.
All plants, with the exception of the Canuk Cookies, appear to be suffering from stunted growth. The leaves appear okay but the growth is very slow. I'm guessing that's probably due to a lack of light. I'm worried about lowering the light again though due to previously mentioned heat issues. These lights run hot! Too hot. Maybe also genetics? The Northern Lights #5 (in front of the Canuk Cookies) was very slow to start but is getting bigger more quickly now. The two seedlings (Peachy CBD and Lemon Pie CBD) are super-slow. Again, I'm guessing it's lack of light but could be heat stress and /or genetics also?
The Canuk Cookies looks okay on top, with the exception of some clawing. The lower leaves, however, are yellowing and dying. It's lost about 3-4 leaves in the last week. I'm thinking under watering +heat stress. What do you guys think?
I finally got a humidifier, which I'll install today. I'm hoping that will help a lot.
Thanks, as always, for any and all advice!
Edit: My camera filter makes these pictures look more yellow than they are in person. The Canuk Cookies does have yellowing on the bottom leaves as mentioned, but the other plants are a healthy green colour.
when you use leds the temps need to be in the low to mid 80s . It has something to do with the leaf surface temp. A search would concur what I’m saying.Nice, thanks for the reply!

So you have your inline fan running only 15 minutes every hour? I've been told that inline fans should be running 24/7 but now I wonder...If it works for you, maybe I should try getting a controller and doing the same.
I'm going to increase the humidity to at least 40-50% and try dialing up the lights after getting that part established. Don't want to change too many things at once or I'll get overwhelmed!
It's funny you know...Growing seems like an easy thing but there are so many factors to consider that you don't know about when starting out. I guess being a beginner is all about learning, even if it's the hard way!
Thanks again, everyone!
Thus is my 1st indoor, so don't take my post as a way of doing it, I was just sharing my experience. I learned the basics reading sites like this and watching YouTube.Nice, thanks for the reply!

How strong is your negative pressure? My heat issues turned out to be the amount of passive intake being insufficient (8" passive intake with a dust filter and a 6" high CFM exhaust fan). Adding a small can fan (AC Infinity Raxial S 8 - like 20-30 US$ fixed my issue.I've already spent so much money on this equipment, I think my wife would kill me if I bought more! Good suggestion though. I started off with a 4 inch fan and quickly realized that was too small. Luckily, I was able to return the 4 inch and get a 6 inch instead. I can't return the 6 inch fan, so I'm stuck with it.
For anyone reading this and wondering about fan sizes, go bigger! It's better to get a bigger one in the beginning, rather than upgrade later on.
Nice, which controlled power outlet do you use? Sounds very useful.The temps will be ok if you adjust the humid like he said, google vpd for more info there. But simply adding the humidifier will lower your temp as well. I have a 8x4, a 4x4 and a 3x3. My 4x4 has the ac infinity program which has temp setting to clear the tent, works and stress free. For my veg/cloning 8x4 I purchased a thermostat controlled power outlet to mock the ac infinity system. It was $20, and works amazing. Basically the outlet has a temp sensor and controller; My 8x4 no longer runs hot ever. Turns the inline on at temp alerts and pulls fresh basement air in to replace the hot air. Gl with it
Never seen that booster before! Looks great but in Canada it's around $100 or $78 USDHow strong is your negative pressure?

I have to double-check, but my lights have IR and-I think-UVB/UVA. Might be wrong about that. Thank you for posting this; I need to get a light meter to check my PPFD levels.Columbia, Jamaica, Mexico, Africa, ect all get hot and the plants thrive. 27-29°C (80-84°F) is about optimal imo.
750 - 850PPFD : 28/29C

Photosynthetic action @ 775PPFD & 1,000PPFD (if you use UVB; dots)

According to the data (and if not using UVB), you get to about 85% of maximum possible photosynthesis around ~775PPFD. Intensities greater than ~775PPFD facilitate slightly greater photosynthetic action but at diminishing returns. And more significantly, with high PPFD comes high heat and possible RH issues, ect. Staying between 750 - 850PPFD in bloom reduces the need to condition your environment while still maximizing (almost) photosythesis per unit area.
According to the data, if you suppliment with UVB, the gains in photosynthesis from increasing PPFD beyond ~775 PPFD are even less pronounced (@~92.5% of max @ 775PPFD).
I've thought of that but here's the problem: My lights have IR/UV light and I'm sitting in close proximity to them. If I understand correctly both IR and UV lights are hard on eyes. I have a pair of welding goggles that I wear when I'm working with the tent flap open. Don't want to damage my eyes.It looks like you have the bottom vents closed.

I wish you nothing but success! Good luck with your future grows!Thus is my 1st indoor, so don't take my post as a way of doing it, I was just sharing my experience. I learned the basics reading sites like this and watching YouTube.
I grew a plant outside last summer and in the middle of summer we had highs of 90F + (in western Canada) and its dry here RH in the low 20's most of the day, and the plant absolutely loved it.... so I figured why should it be any different in a tent?
I'm not really tracking everything either, just set it up and water/feed when it needs... still not dialed in on that yet either.
Some people are insane with OCD micro manage.
All I know is, the plant is happy, and doing its thing.
I was referring to the round vent holes at the bottom of the tent that are closed.I've thought of that but here's the problem: My lights have IR/UV light and I'm sitting in close proximity to them. If I understand correctly both IR and UV lights are hard on eyes. I have a pair of welding goggles that I wear when I'm working with the tent flap open. Don't want to damage my eyes.
If I open the tent flap on the left side in the photo, the light will be shining on me while I work at my desk. Indirect light, but still maybe not good for eyesight? I'm going for the better safe-than-sorry option for now. My wife also has a desk in the same room and I don't want to damage her eyesight also.
