ONA GEL

It does the trick on residual smell from opening and closing the grow room.

I would not use it by itself though without carbon filtration

 

Ona gel will cover up some smell...

But if you have an indoor grow with no carbon filtration for smell, it's gonna be hard to cover all that funk with some Ona gel alone.

If you live in close proximity to others, carbon filtration is a must...otherwise everyone who strolls past your place will smell your grow.

 

Don't have it in the same room as the grow. It supposedly effects the taste and smell of your weed.

 

I heard it's bad for health full of chemicals..if breathed in i wouldn't use it unless in case of emergency..

 

I use Ona block pro, it's excellent at covering up smells and lasts a long time. But like others said, for smoking or opening your tent, it's very helpful, but it's not suitable to cover up the smell of a grow. (And shouldn't be kept in the grow area).
It's also very nice to have around in case of fan breaking, power going out, etc.

 

Also I just thought it comes in different flavours. I haven't used the original (here'd its quite a chemical smell) I got the fresh linin and it is a nice smell.

 

Mine smells like a urinal cake.
