my concept of going vertical in a 5x5 tent

The ideas simple. I was going to hang a 1000w bulb with no reflector directly in the middle of the tent. Instead of putting a fan underneath it to blow on it i was going to put my humidifier under it which blows a good amount of air straight up. I think this way i can kill 2 birds with 1 stone, dehumidify my room and cool it down essentially. I was going to put my carbon filter/fan right above the bulb to suck that air out from the humidifier/bulb. im probably doing to put 4 plants inside, 1 in each corner around the bulb. Im pretty set on doing this but i wanted some advice or feedback on what could be done to improve it. any tips on vertical growing would be great cause ive never done it before.

Yeah it will work assuming that dehumidifier blows even a modest amount of air and your extraction system is up to par. I'm sure it is. Make sure you have a nice sativa hybrid for maximum results.

I've done something similar to this a number of times, in different size tents.

Placing a dehumidifier in there wouldn't be my first option. Having your dehumidifier outside your tent will give you the same result by dehumidifying the air being exhanged into the room, without it taking up floor space in the tent, and without dumping heat into the tent.

A 1000W bulb in a 5x5 will cause your RH to blow through the roof, and then the dehumidifier will try to dehumidify, only creating a vicious cycle of heat/transpiration/RH rise/dehumidifty + Heat, and then it repeats. My personal opinion would simply remove the dehumidifier from inside the tent and place it outside. If you have your exhaust on, it will be taking the newly dehumidified air and dumping it out of the tent anyway making it less than optimal - very little dehumidified air will stay in the tent at that point (it may make it's way back when your room cycles enough air, but still no reason to have it inside taking up valuable floor space).

I personally just like to cycle the air from the entire room - and then you can easily control the rooms humidity with your dehumidifier, and cycle that air into the tent. I've done 8x8s with 3000w. The easiest way to keep humidity and temps in check was simple air exhange on something like a HUM-1 from C.A.P. or some other environmental controller. I've never had a dehumidifier in my tent, but always have one in the room it's in!

I think the filter/fan above your bulb is a great idea for air exchange, and to pull the heat from the bulb. If you're not using sunpulse UV bulbs, you could hook up a cool tube over your bulb, right before the fan so you could have your plants get closer to the bulb and not worry about them getting burnt (5x5 can get real small, real quick if you over-veg). If you are using Sunpulse though, it is recommended to not use glass around the bulb if you want maximum UV output.

However, sucking the air "right above the bulb" or sucking the air from the top of the tent really won't make that much of a difference as long as you're moving a good amount of air. Any 6"+ exhaust fan will move PLENTY of air to keep that temperature stable anyhow.

Listen to what dubdeuce said. Great advice. Also, think about 2 things with vertical growing.

1. DO NOT bump into that light with your bare skin or you'll be smelling bacon LOL

2. Get some glasses, because you will have light all up in yo face gurl.

Good luck and have fun cowboy.

Get welding goggles if you're gonna work with the light on IMO.

I agree the humidifier outside would be far more optimal. The space is precious and the added heat just means your exhaust will be working harder than it has to.

good advice but he said a HUMIDIFIER, not a de-humidifier...lol
yeah it will work but you are going to have to tinker with the system to see what is most effective for YOU...
Also, just wear glasses when you do go in there and DO NOT look into the light, it burns and you will see tracers for like 15 min...I KNOW!lol
i hang a towel around my cool tube while im the room working and this helps with light and heat, then you won't get burnt...good luck man and send some pics this way..

Im not running an intake, just exhaust. So it kinda has to be inside.

You can run it outside if you're pulling air from the outside. Dehumidify before it ever gets in. Will moderate temperature increase a bit. What's your typical relative humidity without it?

If you're running a 5x5 tent I'd suggest a 6" vortex style exhaust. 500cfm or so.

Actually, he said both! First he said he was placing a humidifier in there, but in the same paragraph said he could kill 2 with 1 and "dehumidify" the area. Tents are Heat/Humidity Traps. There is no need for a humidifier in your tent, just a fan on a temp/humidity control.

i have a cool idea... i dont know if u can do it with weed but you know what a topsy turvy is? maybe u could grow some upside down and train em towards the light. be careful watering though dont want to get that hot bulb wet! :fire: oh yeah and ive heard that 600W lights > 1000W lights cause more lumens per watt. and yes less watts less heat, in that tent u dont want to have humidity problems.. if u have the light already look into cool tubes! maybe u can make an air cooled one of some sort and shoot it out the top of ur tent

I can't believe you guys are supporting cooling a 1k with a dehumidifier. This is funny shit.

Sometimes you have to make things work. Really he's cooling his tent with whatever his extraction fan is. I assumed space was an issue for him. A shitty little fan is enough to get the warm air moving from the light to wherever he has his exhaust setup. You don't need much at all as you aren't trapping heat with a reflector. Granted putting a dehumidifier inside your tent is less than ideal for many reasons, but like I said, sometimes you need to make things work and it could work well enough for his purposes depending on it's design.

A little added heat might be the trade off he has to sacrifice to keep humidity in check.

It's obviously less than an ideal solution.
