I put about 2 non stop years on one before I opened it up and swapped out the carbon. I use 6 inch diameter filters that are 24 inches long.

so i can actually open it and swap out the carbon. I should take some time and figure it out!!! My current filter is 4 inch diameter and about 12 inch long. It only last 4 months.
@Skybound How long your diy carbon filter last? I am thinking to build one myself, since I am able to buy all those things in local store.
I just brought this activated carbon pallets 4mm. Couldn't find more fine grain carbon though. Should I smash it into pieces?

If the carbon is too small, it will pack too tightly and air won't flow through it and you need air to flow as good as possible. The DIY filter lasted maybe a few months, surely till the end of my first grow. Remember, this is just a band aide, not a long term solution. The solution is to buy a bigger filter.
If you want, you can rotate your filter which essentially swaps the inlet with the end cap. Stand the filter on the cap and remove the inlet, then put a piece of cardboard on top and flip it over, remove the end cap and put the inlet on that side. Then flip it back over and put the end cap where the inlet used to be. Doing this will put the side of the filter that was used least closest to the inlet.

If your unit is riveted, you can drill out the rivets and use new pop rivets, or any threaded screw that will tightly fit into the existing rivet holes. You may also add some of your new carbon to what was in the filter if you think doing do will take up any empty spaces. Air, just like water will follow the path of least resistance and if there isn't a sufficient enough amount of carbon in the filter, air flow will prefer any voids where it also doesn't get filtered. If you need to additionally settle all of the carbon inside the filter, I suggest to NOT pack the carbon into the filter manually, but rather put the filter on a flimsy table and beat the table with 2 rubber mallets by making a drum roll. Anything that will produce high energy pulses will do as that will vibrate the carbon into the lowest position possible without crushing the carbon in the process. You can definitely get away with crushing some carbon, but the more that is crushed, the more restriction to air flow will be the result and that will make your fan work a lot harder and consume more electricity while in the same breath weakening the windings inside the fan.

It works, i made a extra small filter and it works. So I decide to buy more things to make a larger filter, main task is to increase air flow.
Not sure will it work properly. My nose fatigue to the odor. Have to wait my wife to tell me tomorrow.

Do you own a 3D printer by chance? I bet you can make a great filter on a printer.

No i do not own 3D printer. But now you mention about 3D printer, maybe i can call some company print the filter for me.
I love your ingenuity - that is awesome and looks like it's going to do the job for you. Let us know what the wife says!

It work like a charm.
No more odor according to my wife.The only down side is that I can't hang it up, so it's gonna cost some space in tent.

Can you hang it outside the tent and suck from the tent and blow through the filter? That's how my extraction is configured.
Glad to hear it beat the wife’s smell test, that’s awesome!

Yes i can, but i have to arrange the aluduct again. I am so lazy, so i'll wait until i got no space.

Remember that 2 clones? I put them inside the tent with White Widow. Something strange happens. It grow like White Widow now. Notice how the old leaves remain like sativa, and the new leaves grow like indica. Will it turn and become WW eventually?

The new leaf fingers didn't grow long enough to appear as the ones that did. Also, you don't have to reconfig your exhaust, I was just letting you know that it doesn't matter if you suck through the filter, or blow stinky air into it, the end result will be the same, but you do have options to reclaim the lost space.

Day 35, they are into flowering now. They are too high and i can't raise the LED light anymore higher. What can i do to prevent them from getting light stress?

I hang minor weights from the tops, just enough to redirect the tops out of the danger zone which in my case is between the COBs. If that won't work, I'll tie the branch to a fixed point on the side. If that also don't work, there's a technique called "super cropping". SC is when you crush the branch between your thumb and finger to soften and weaken the branch at that point so you can fold it in half. FWIW, I try to not us SC, but only because I lack the patience to crush the branch correctly and always end up splitting the branch vertically. When that happens, you can still lay the branch down, but it takes a few added days to recover and resume growing as normally. If you do get it right though, you essentially crush the branch into the center with your fingers, and from many different angles. If you can crush without splitting, you'll be in fantastic shape as the weakened point will form a knuckle which can hold fluids and improves flow through that point.

I watched super cropping on youtube, i do not have the guts to bend them.
But i just saw some people use net to control height or use it as LST. I just make myself a nylon net to limited their height. Hope it'll last until i come up with a better solution.

Scrog nets will only hold them back briefly and will serve later on as branch support, but for the first 2-3 weeks of bloom, all branches that are going to stretch definitely will do just that and it is then that you'll need to try other things. FYI, Scrog is short for "SCReen Of Green".
