What about bringing in cold air from outside into the tent?It's 40 outside at portable a.c. is out of the question until late spring
Is your ballast dimmable?Hello everyone,
I setup my new 4x4 grow tent earlier this week and powered it up to dial in my temp before I start my grow. Well turns out originally I was getting temperatures of 85 to 87. I spoke to a local grown shop and he told me it was cause of my in line fan being subpar so I replaced my active air 6 inch with a max fan pro series 6 inch which in turn only helped by 1 to 2 degrees at then most. So I decided maybe I should buy new ducting rather them the crap I had from lowes that was 6 years old but never used. Luckily it lowered my temp I had a steady 77 on top of my hood and 79.1 on the floor 3 hours later the tent climbed over 80 it's currently been on almost 5 hours I got 82.9 on top of hood 84.9 floor.
So here's a break down the room that the tent is in was 65 before the tent came on the setup is
4x4x72 lighthouse hydroponic tent
600w hps
6 inch max fan pro series
Ventilation setup
Carbon filter - (pull) fan (push) - duct - light - exhaust out door (door cracked just enough for vent to go into hall)
Currently the carbon filter is disconnected since it is a 4 inch carbon filter with a 6 to 4 flange I figured at first that may have have been the cause.
So I think I may know what my problem is but would like some insight to see if anyone comes up with something different.
I am thinking I may have to run a active intake instead of the passive vents on the bottom I believe the vents that are open on the tent are reflecting off my white walls and heating up the room the tent is in thus raising my Temps any ideas?
And if this is what I need can I get away with a 4 inch intake and how much come would I need?
Please help thanks in advance!
This. Your room will cool when your fan is at the end of your run after everything. You also are pulling air through your carbon filter too fast with your current set upWell I see you already purchased the fan, but if you haven't plugged it in yet I would simply change the placement of your fan. Instead just have the ducting run from your carbon filter, straight into the light/hood, and your fan pulling air directly from the hood. In line fans work much more efficiently when pulling air than pushing. And if you didn't already buy the 6 inch fan, I would say another 4inch fan would do the trick, if placed where your current fan is along with the setup I described.
Ambient temperature is the biggest factor here. You can try to pull air in faster by adding a fan used exclusively for that purpose. But the rate at which your removing heat hasn't increased. It's better to eliminate the issue than to constantly fight it. Make sense. The faster you can pull that air past the light, the cooler the room will be. At the same time you want to make sure your carbon filter is rated to handle the cfm rating, other wise your filter will not be doing its job effectively. Hope that helps.
Lmao... This is absolutely wrong. Go to a physics class.With fans, blowing or sucking doesn't effect or change the efficiency. A lot would argue blowing is actually better but who knows. You'll have to break out that other fan unless you can vent cold air in to the tent like skyrocket said, that would be your best option
Read some more buddy, or better yet try it out for yourself, if you did you'd see that blowing or sucking the air generally doesn't make a difference in temp of your tent. Here, I did a little research for you to show you that, as I said, a lot of people would say blowing air is better....Lmao... This is absolutely wrong. Go to a physics class.

You don't have to be enrolled in a physics class to understand something like ventilation in a small tent
As well as the fabric filter that goes on the outside of the scrubber. It's supposed to catch larger dust and debris before hitting the carbon filter. Blowing out would do the opposite and may end up blowing little fibers from the pre-filter around your tent.Lol..i can find a bunch of links in my favor as well. The bottom line is that there are benefits in growing to both configurations however you said "blowing or sucking doesn't change the efficiency" and that is simply not true. Blowing is more efficient in a small run or at lower speeds. Sucking is more efficient at higher speeds or anytime a drag will be added to the airflow, equipment, bends, etc.. Think of it like sound. Depending on your setup the efficiency does vary method to method. In most cases it is more efficient to pull if you have a single fan setup. Carbon filters are made to be pulled through because pulling is the better option, ok ok and maybe it also has to do with possibility of mess
Also do this. I draw in 20 degree colorado nightime air in from outside. I use a 6 inch fan with a power reducing controller, set it to medium fan power and point the air to pass right underneath the hoods. Stays 68 to 72 in my grow.What about bringing in cold air from outside into the tent?
Absolutely! This is what I was referring to when I mentioned using a small fan to remove the standing heat under the hood. If that heat isn't constantly removed, it will sit there like a hot pocket of air, accumulating.Also do this. I draw in 20 degree colorado nightime air in from outside.
