The 4x4 Grow Tent Club

Or would it not leak out the vents because of the negative pressure from the filter pulling the air upward away from the vents?

This, generally. I mean... I wouldn't store fresh corpses in there or anything. But that odor would probably be pretty well concealed, too, lol.
 
You will need to keep your bottom vents open unless you install an intake fan. There is no smell as the extractor keeps everything moving up. I did my grow with the flaps open. It was no issue.

This is music to my ears =)

Does it matter what type of ducting I use? Is there any specific type I need to use ie Insulated vs non-insulated etc. I'm looking on amazon and can't tell if there are different types aside from insulated vs non.

Thanks!
 
I used normal ducting. I also set up the filter and fan on the outside of my tent and poked the ducting inside the tent. It worked fine. I was very worried about the smell. Just wasn't an issue. The big charcoal filter is fantastic.
 
I made a charcoal filter with a pretzel tub, some window screen, aquarium sealant and activated charcoal I had for the fish tank. Had to tweak how much charcoal I had in it but it's working great now!!
 
Just got my tent today!! Super excited, now I can get the room ready for flower.
I need to build my screen and let her adjust to the change. Probably 2 more weeks till I flip her to 12-12.

What kind of extractor do you have? You need to open up the bottom vents unless you have an intake fan. The tents are very well sealed, so if you zip everything up you will have big problems.

Happy growing. You're off to a good start. :thumb::goodjob::cheertwo:
 
No exhaust vent on the tent. I just have a vent open on the bottom and the big 6 inch open on the top to act like a chimney. I have a fan inside the tent. Temps are fine so far. No worries yet.
Eventually I will exhaust it I to my flower room which is exhausted outside.
 
Hey guys I'm just here to show you my new setup in my 4 by 4 tent. I'm approaching week 4 of vegetation from seed.
Decided to go with a new light this time around instead of the LED. I'm running the Sun System with a Philips 315 LEC bulb. This light seems like it's going to be nice!

Yeah last time I had to do some extra work because I didn't have it. This is how I did it last grow with 7 gallon smart pots (I'll never do that again). I cut a corner of my top try out so I could get my vacuum in to get all the water out.

So I have my 3x3x5 tent all sealed up except for a computer fan on the top.
Temp is @70. I'm running a 300W full spectrum LED
Idk why people have problems with temps in their tents. Mine is in my basement and I'm in MA. It was in the 50's last night!

Got my new light in yesterday!! Spent some time this weekend setting up my carbon filter and run off system, almost done having everything set up. Just waiting on 2 2' T5 HO single bulb lamps and some specialized UVA/B bulbs to come in so I can set those up, and just need to build my net.

Big shout out to our sponsor Techman(SunPlus), in my limited time so far this light seems phenominal for the current price, seems like it'll have no problems flowering a 4'x4' tent.

In the below pic light is @36", I'm pulling 900-1000 umol/s at the top of the plants, and in the furthest section of the tent I was only able to find a couple spots that dipped to about 200-250 so far, the majority of the outer perimiter was still puling 400-500 umol/s, so I'm very pleased with my findings so far.
