^ I was thinking about that, but do you have it mounted to the framework of your house? does it cause vibration still?

If you mount it to the framework of the house you'll still get vibration noise.

The only way I've found that works great is bungees.

Let me find a pic for you of mine.

If you look at the fan, you can clearly see the silver metal bracket that generally comes with fans. In the ceiling are eye hooks then I used the bungee to position the fan where I wanted it.

got a question about this, so if I push air through the tube and out the top, where should the fan itself be? still at the top of the room or more towards the bottom? right in the middle?

as far as I'm visualizing it would go [fan --> flex duct --> cooltube --> flex duct --> attic] I guess I could put some flex on the intake of the fan still and just put that where ever I want to suck the air from. but if I am using the fan as both cooling for the light as well as exhaust for my room what would be optimal placement?

You want the fan sucking air out of the top of the tent so you get the hottest air out. It's still plenty cool enough to cool your light.

Yeah, I see what you got going on in there... next time I have some time I will try and rig something like that up.... I have a lot of paracord, I'll probably try that stuff first, see if it helps. I would have to go buy some bungee cords if those are absolutely necessary.

yesterday I took the fan off the wall and I just set it on the wire shelf at the top of my closet, on top of a cushion to help quell the vibration.... I dont know how much it helped... I wonder if you can get an app for your phone that reads dB? that would give me a solid answer.

Bungees aren't necessary they're just easy and elasticated.

I've got two 400 watt HPS lights. Just waiting on flower time to join the club. How much space can a 400 cover? Would a 4'x4' or 5'x5' area for each light be too large to get decent buds?

That'd be the one. I don't think I'd ever heard it used outside of a very competitive Scrabble game before today and then two people in one day.

are you a promoter of defoliation? just in the lower leaves or???

I believe in only have enough plant matter to make use of the penetration power if your light.

This technique is called "mainlining" a user called NUGBUCKETS has a tutorial about it.


I use a 400w obviously that why I'm in here lol. So at best without a big dense canopy I get around 2-2.5ft of usable light penetration. So anything that's lower than this point from my lamp down gets removed.

These girls are standing at almost 2ft tall and are only 6 days into 12/12.

Jon you mean 2.5ft from the bulb right? I find about 12-15" below the canopy it's pretty fucking dark in my grow so I try to take off everything down there. I was doing 18" but found I needed to be more aggressive.

Yes from the bulb down. The plants in question in the pics have currently about 10-14" of growth left on them. Currently though the canopy isn't too dense right now.

I may strip off more over the next 8 days or so.

But I agree with you.

You generally find people moaning about density and shitty popcorn are those people that haven't trained or pruned based on their lighting being used.

Ain't that the fucking truth! My goal is always to get an evenly canopy where I get growth all through the useful light zone. The better I do at that the better my yields and are. Once I have that I just try to just give the plants what they need to do their thing and they always do it really well.
