Eliminate all unwanted smells with this doo-hickey I created. The additional fan pulls air more efficiently through grobo’s carbon filter pulling air through the inlet and all leaks around box. Smells can not escape.
You can use it with just the fan up until early flower stage, then when the magic starts to happen you can slap a carbon canister on it. There’s even a hook in the box to hang your gas station scent trees,
(don’t do that though) or any scent boosters you like with out affecting the plants atmosphere. It’s nice. Trust me. I can invite the elders over wants this quarantine is over. We all know the grobo is the shiznit, it just needed a lil razzledazzle to make it all complete. I hope this helps, stay safe family.
