Grobo Smell elimination MOD. Stay discrete with this new add on. You can invite grandma over again

Just a heads up I have messaged this gentleman 3 times and gotten no response. I like the suggestion about the one on Amazon that doesn’t attach.

I like this suggestion. I have a question, did it effect the temp or humidity? Also did you go thru the flowering and harvest with no smell? Thanks for this suggestion.

I’ll think of ordering one after 4 grows under my belt. :+1:t5:

I haven’t gone through the whole process but have this in hand to attach with magnet strips if needed. 12 x 12 x 2.5 Inch ABS Plastic Flange with 4 Inch OD Opening for Dust Collector Systems 73467

No impact or changes to what’s happening inside the box re: humidity or temps.

Thanks so much for the share.
See ya around.
Happy Growing.

I nornally use a loose inline fan and carbon filter in the room where I’m growing. I let it run 24/7. No odor what so ever and I’m growing about 10+ plants at a time

What a great build.
I saw you would like an address for calc on mailing.
I live in the burbs of Chicago.

When you have time, hope t o hear from you,

Order you own. I tied to reach them 3 or 4!times.


Thanks for the info.

Installed mine last night.


Can you use that plate on the back of the Grobo and vent direct to a window somehow? I have a
small window in the room I can vent from, just want to make sure it is “discrete”. The window is to narrow for a normal dual exhaust fan or anything like that.

How did you attached to the back of the Grobo? Do you have those pictures?

Were you able to actually do it without screwing it on? I was really considering this as I get closer to transition it is smelling more and more than I was actually hoping for!

Magnetic tape is what I used when running something like this.

I attached it with double sided tape and it doesn’t move at all.

You don’t have to vent it out a window. I have no smell at all and I’m almost at harvest. If you vent outside with no carbon filter you will be sharing it with the entire neighborhood.


Thanks, I am just dabbling right now. I can add a filter too if I need. I mostly want to get the window, the vent and things setup until the Grobo 2 comes. It should look just like a normal dryer vent. I probably will not need to run it until 2 are going. The little smell now I can take care of.

Just attached mine after waiting on them to come in stock! Works like a charm with the smell! Thanks for the idea :muscle:t5:


Perfect and under $100. Can’t beat it.

I must ask what did you do to keep the temp in chk? I notice my temp rising and humidity decreasing already along with my water temp going up all things I have before been well in control of with the two additional fans I have added inside myself.
