Do you filter your intake?

Hey guys,

Im sure we have all had to take off our filter covers from time to time for a good wash. Im using 1 tent to feed another atm, helps with heating. Ive been quite shocked at the different between the 2 filter covers. Both have been in there for 2 grows.

Tent feeding - unfiltered intake:

It really shows the difference, these are srticky girls to, the thought of all that dust . Everyone has to change filters so should have/end up with one spare.

I've never seen one that dirty tbh... Maybe your getting cement dust from the floor?

I use a old 4 inch rhino hobby to cover my outside air to inside grow space air intake, then every ducting has at least a double layer of stockings or a square of cut filter cover which i cover all the air flow joins with

i had concern of passing pollen between spaces and these controls seem to have contained it well

I had some fungus gnats in the basil in our flat when I started so I was quite keen not to get them in my grow. This is why I stuck a filter in front of my passive intake. I used a single layer of this: https://www.amazon.co.uk/gp/product/B07 ... UTF8&psc=1 and it seems to work quite well... The duct tape doesn't stick well on the tent, but the suction of the fan keeps it sucked right to the inlet. I'm growing autos so light leaks are no issue for me, but you might have to use multiple layers and extra caution to make it light proof. It seems to work well and I'll have enough of it for multiple grows even if I chuck it out at the end of each run.

I havE a passive inlet but my CF covers are usually dirty after each grow, i think that`s down to big dog walking in and out of kitchen when he`s been outside freating dust or whatever, feck knows tbh. :)

Hi,

I plan to cut a piece of washable air conditioner/furnace type filter on intake just to keep some of the dust and dirt out.
