Honestly this is my first time using one I've bought usually my home made ones last for 6 months in my small grow. I heard a year, but some folks replace when they change their bulbs, I think those guys are the big time folks.
I just replace the carbon and inner screen in the carbon filters, once per run, cheap enough. The HEPA filters go about six months tops. Expensive over here, kinda getting over them.
I ordered my hood without clicking gift. Had a ups guy walk up to my door with a look on his face like he really didn't want to deliver the package the way it was, walked threw my 100+ house condo to get to my door. My heart kind of sank a bit. But no bad things came of it. Big ass Hydrofarm box with a nice picture of the hood on the side.
Exactly why I order it with gift wrap. I've had a similar instance
BRILLIANT! Plus rep if i still could. I make my own biocarbon so I have enough good hardwood char around. This is NICE. Right up my alley. Thanks for sharing! I am building one. This is going to neaten things up a bit around here.I have a can with a box around it. My vert room vents to the can. The led flower vent to the male cab, and it runs in to the box just above the can filter on the back. I have not closed in the veg yet, but when i do i jush cut a new port in the box. It is filled with natural hard wood charcoal, and i change it twice a year

I might have confused myself but I think I am a puller, I let the can fan pull all the air through the charcoal filter and out. I also have one can filter in the middle of the room just cleaning the air and blowing cold air up.
Pull this way..
If you have low humidity that will prevent the filters from going out. I was told if the humidity goes above 50% that the coal gets wet and stops working. Could be just bullshit but was told to me from a grower who has had to replace multiple filters for not being able to control the humidity of 500 plants lol.
I do the same as you minus the light
About five years ago I said to myself "in about 5 years the LED technology will be there. I'll check back later." (after my old "new means better" partner fucked off a 90 plant cotton candy kush run using some stupid kessil LED lights.)
You should check out the subforum for leds, shit hascome a long way even in the last 2 years.
Agreed, if you can DIY, grab some Cree, or Vero, COB's, and get soldering. There are a bunch of threads to help walk you threw construction in the LED subforum.
bust out the chem3 please.
