is it okay if I have two different grow lights in 1 grow tent my oy concern is like maybe one grow light will overcome the other or heat up the other one or something

I literally asked this exact same question months ago when I set my first tent up. In a lot of cases it will benefit you. Like 2feather I have mars hydro ts 600 x2 and and other lights that have more UV to balance it out. If your worried about heat point a fan at em or get an ac

yes ever since I have two lights my grow tents temperature rocketed I mean not to the point where it's harmful to the plants but to the point where it's not suitable temp for them I'm just going to probably put another clip fan in the tent that should probably cool down.. 2 clip fans should be alright you think..?

Yeah you can put the ac in your room and then the air intake will be cooler just make sure your exhaust goes outside or you’ll just be blowing hot air back into your room.

I have a fan blowing air into my tent and then I have my filter hung and connected to an exhaust fan pulling the air the filter and then out of the tent.

Try balancing the cfm between the intake and exhaust. The filter creates more resistance on the exhaust side.

I'm wrestling with this a bit too; ended up thinking about micro-climatology in grow tents while on a smoke break (Ruby Slippers, I need more of that strain...). I started thinking of my tent in meteorological terms:

Is your tent inflated (positive pressure)?
Positive pressure will increase temps and decrease humidity - pushing in more air than you are exhausting.
Stronger intake fan, weaker exhaust (High pressure = low humidity)
** Fan will become less effective as tent pressure increases; eventually no effect will be felt at the vent.

Is your tent sucking in (negative pressure)
Negative pressure will act almost opposite - temps drop / humidity rises
This effect is negated a bit by the lights.
Weaker flowing fans on intake, strongest flow exhausting out roof / up high (Low pressure = high humidity).
**As above, the fan will become ineffective as the negative pressure overcomes the fan.

I was trying to cool my tent by sucking in more air from down low, This increased the air pressure inside the tent, the denser air carried the heat of my light better, so the cool air warmed up, and the high pressure bit me again by stealing my humidity. Balanced thesystem and all is (sort of) under control.

Hope that helps.

so your not filtering your exhaust air?

sorry I'm worded that wrong my carbon air filter is inside my tent my inline fan is outside I'm using a small fan for an exhaust on top the 10

Actually I have negative pressure going on right now and my humidity is dropping it's a v
at a temperature of 81 degrees and humidity temp of level 55.. I usually have my humidity temperature is around 60---65 however ever since I got a second light it drops in my temperature rises I'm having a hard time controlling that but my plants are doing okay

When trying to balance out temps relative to humidity, I try to remember as temps rise the air will hold more moisture. So you'll need to add humidity to hit that vpd sweet spot at higher temps 78-84 for example.
Then once you flip pull the humidifier and fire up the dehumidifier for the remainder. Slowly drop temps as you finish flower to mimic fall season.
When I hit that vpd sweet spot at 82-84 I notice major accelerated growth.

Huh - that worked for me, quickly too.
I also used a hand sprayer, and placed plates with soaked paper towels to increase humidity a bit more. I'm expecting to fight low RH until I get more biomass growing in the tent.

Hope you can find a solution - I'll post again if I can nail it down here.

Ooohhh i need a okay a dehumidifier to see what I've been doing is Ivan unplugging my inline fan that's connected to my carbon filter and that raises my humidity level but I have to keep track so I didn't know if to get a dehumidifier..thank u

I just now I unplugged my carbon filter fan in it raise my humidity level 80.. I can have my dehumidifier is not working it's only been an average of 55 humidity and I needed around 60 it's a week one as a Vicks and I had to get a better one I have some cool plans I'll post a picture

You absolutely can use different lights. I looked this up a few months ago as I was using 2 different lights at the time, and I learned that light cannot block light lol even if it is not visible to the naked human eye, lights shine through eachother. I hope this helps.
