Hey @SWSVIC
3+ months later with this setup, would you change anything?? I’m about to get to that point and I’m going to pretty much copy your setup. Figured I’d ask if you would change anything if you could go back!
Thanks homie

Honestly there is nothing I would change, I love it. I do plan on taking it a little further by upgrading the fan and carbon filter prior to my next grow.

I just tried installing this system with only one connection from the flange piece to the inline fan to get some heat reduction going.
Only bad part about it was that my Grobo unit back plate doesnt sit flush with the shell and it isn’t flat, so this doesn’t exactly fit 100% and leaves some pretty large air gaps… I just taped around it to make a seal for now, but now it’s not removable.
There is an option to POSSIBLY double layer the sticky magnets on a spot or two and that MIGHT allow it to sit flush with the Grobo, but it would be probably be pure luck.
The right side of my Grobo is also kinda bent so I see some light coming out compared to the left side which sits flush -_-

I haven’t put mine on yet. But this is good to know! I’ll report back my findings
Just fill in the areas with an extra layer of magnets as I did. PS: I’ve never taken mine off nor do I really ever see a need to. Thus I have taped it off using white electrical tape. Looks great and creates a perfect seal.

Ah okay thanks. I guess I didn’t read the part about double layering the magnets, once I get a day with stable temps in the Grobo I’ll try to remove my tape and add another layer of magnets and see if that helps. For now it’s taped on.

For the DIY hack and for the Disclaimer lol

Okay so since I finally got my temperatures at a safe spot to do some adjusting, I removed the flange and added two layers of magnets on the vertical short sides because those are the ones that aren’t sitting flush. The horizontal top and bottom sides were fine.
However, a 2nd layer of magnets isnt enough to make it sit flush either, and it looks like a third would be too much. I ended up re-taping in a nicer manner that looks much better and with the double layer magnets its a smaller air gap, so I think it’s a win win.
I looked at your pic; your Grobo’s large back plating sits flush with your Grobo… like I said, mine is bent from either shipping or bad construction, so it’s never going to fit right as far as I can tell.
With that being said though, I’m not upset at all, because with the tape and extra magnets it still works pretty well.
This system provides at least 4-5 degrees of heat reduction for me from what I’ve noticed so far.

Happy to hear it, sort of the nature of the beast when using a removable setup. Of course the issue could have been solved with a gasket and screwing the joiner flange Directly into the back of the unit, but the less invasive approach was much more appealing to me. Also when coupled with the white electrical tape seal, the same results are achieved. I have another environment MOD which I will be implementing prior to my next grow. Stay tuned brother!
Yeah the less invasive approach you took was what was appealing to me as well. I definitely didn’t wanna do anything to my Grobo that could potentially end in me destroying it.
It’s definitely working, I actually am getting about 6 degrees of heat reduction from when I had the fan off/system disconnected until letting it run the past 45 minutes… I think the extra adjustments actually are making a better seal.
I’ll be watchin for the new new

Get yourself some white electrical tape and seal off every point that you see light leakage.

Good idea… didn’t think about doing that to be honest, was more focused on the flange.
Probably gonna be better for maximizing the carbon filter once my plant is in flower too I would imagine…Haven’t added that on past the inline fan yet, no need atm, but plan on getting it set up in due time.

Agreed, I did the same.

I used clear packaging tape to seal up the gaps on that back/side panel

I kinda want to do a test to see if turning the inline fan off for the system is viable, as in, will the exhaust still be able to escape and not suffocate the Grobo? You have any experience with this? Since it’s taped its not really removable as easy as magnets would be.
Like I’d want to believe that the exhaust will still find its way through the ducting, but I have a fear it might not have enough force to escape?
yeah it could overheat in that scenario

It’s viable, I’ve tried. I shut my inline fan off at night when the lights go out as my house is another 3-4 degrees cooler when I sleep. I would not shut it off with lights on unless your place is in the 60’s.

I have only turned the fan off for a short period (once) to test the efficacy of the heat/smell reduction system. I would not recommend turning it off for an extended period of time.
