Hey tommy thanks for your reply! I’ll raise my lights and see if that helps with the temp! They are 640watt but turned them down with the dimmer to about 40% light strength
Yeah…you can show your grow…no problem.
Also, what stage of growth are you in? If the highest temp you got to was 82.5, that’s not too bad. Personally I could live with that and would love that humidity. I’m in Florida, so pretty tough here. On the Internet, I see high temp thresholds of 75-85, so 82.5 seems okay…but it’s what you’re comfortable and ultimately what the plants like.
Ok cool, I will send a pic right now after this comment. And about what stage Of growth i Am in so something that has confused me… to my understanding there’s a seedling, veg, and flower stage. I see people veg for 4 weeks but does that include the seedling stage? Maybe you can tell me by this info… I planted on 5/30/20, they appeared above soil on 5/31. From 5/31- 6/11/20 they were win 18oz red solo cups on a light cycle of 18/6 with humidity around 74%. On 6/12/20 I transplanted into 5 gal fabric pots with the same 18/6 light cycle but now humidity is around 66-70% and I also began to introduce nuits but at less then half of what the fox farms nuits recommended. So, am in “veg” mode From 6/12/20 when my plants were transplanted or have I been in veg mode all along since my seedling sprouted? I just don’t know when veg actually occurs after the seedling basically…
People probably have a slightly different idea of when those transitions occur. Seedling is from seed to a couple/few nodes of growth. Veg is from then to when it starts to flower, and flower after that. Don’t sweat the exact transitions. Just make sure you’re environment is good for that stage of growth. I’ve found for me, the most critical is during flower, especially late flower when the buds are packing on weight. In my environment, that’s when the RH can really hurt me and cause mold in the buds to form. The timeline you gave sounds good. Since you’re in flower right now, your temp and RH are decent. It would be good to get the temp down a little, but you’re in an okay spot where I would be okay with it. Can you get your lung room (the room where the tent is sucking it’s air from) cooler to maybe knock the tent temp a couple degrees to get it below 80? Like I said though…not to bad currently, IMO.
One thing I see right off the bat is to mount your LED drivers outside the tent. That’s what I do to reduce some heat. Also, some dehumidifiers put off heat. Does yours? Or is yours one of those types that don’t have a compressor causing heat and noise?
Also, I’m assuming it’s just not in the photo you took, but I don’t see your inline fan.
What are led drivers? The lights came assembled like that all I did was just attach to ratchet straps. And I don’t have a dehumidifier in the tent cause humidity control hasn’t been a problem yet but I do have a small dehumidifier that I already purchased but have not used yet. Here is a better picture of the tent…
What is that device at the back, left of the tent? A humidifier?
The drivers are the silver boxes mounted the LED frame. You can detach those, mount those outside the tent, and run wires inside to the LED.
Oh wow ok I never thought of that for the led drivers! I will look into that. And yes the left corner device is my Honeywell evaporative humidifier
At this point in your grow, I wouldn’t think you would need the carbon filter attached. I would detach that carbon filter until flowering when it’s needed to get rid of smell. Taking it off will also improve air flow, even though that T8 is a monster for a 4x4. Also, it will just make your carbon filter last longer.
Yeah o didn’t realize how monster the T8 was going to be. Reason I bought it was cause I thought I would need it for temp control but I really don’t know what I need or needed… wish I came across this community before all my purchases. Do you think if I purchase an additional fan to put into my vent at the bottom of my tent, that that would make a difference. You see what I have to rely on for bringing air back in… open tent flaps and just those small fans for circulation…
You’re’ good with the T8…it’s always better to oversize than be under. This way you can run that T8 at 50% and get the circulation you need. Plus, when you do need the carbon filter, you will still be getting good circulation because adding the filter does reduce the efficiency of the fan, and you can bump up the speed on your T8 a couple notches. Don’t be afraid to turn that thing up a couple notches now (after removing the carbon filter) to see what impact that has as well.
Do the walls of your tent slightly suck in with it closed? If not, crank your T8 up some.
For what you have, I would think the fans you have in the tent are good. You may need to reconfigure there orientation when the plants get bigger though.

Wow thank you for all the help man, really appreciate it! I will remove the carbon filter and see what impact that has. My T8 is set to the 3rd fan speed and the tent walls suck in very nicely even with the tent flap open! I will apply your suggestions and see what helps!

If you need to put that T8 to full use, you can get support poles to keep the tent from sucking in due to the negative pressure. Gorilla Grow Tents has a kit they call “high cfm kit” You can see them in use in my tent

LOL…very true…that T8 will make that 4x4 fold up. Also, curious why you have your filter on the floor? Wouldn’t it be better to have it sucking the hot air from the top of the tent?
Plants looking nice, btw.
Wow thank you for that! I’ve noticed that when I raise my T8 to a speed of about 5, I start seeing a little bend in the tent so I was always cautious not to go near that speed, I will certainly loom into those poles!
I get that question a lot, and for whatever reason my setup just seems to perform better that way. Don’t really know exactly why
