hi folks anyone used or using SAD IONISER or similar bulbs ive just invested in some i just want to know if they work do they stop the smell or eradicate some of it.... regards herbal

They are useful for small grows such as your freezer grow, they will reduce some of the smell. I would put a neutradol in there as well. The downside to them is the ioniser will not work during lights off. Also useful in the room you smoke in to help reduce smells along with a ambi pure. Not as efficient as a carbon filter though.

Yeah i've got something similar to it - an 'EzeeBreathe', put a few drops of this liquid stuff in it then turn it on, works well if you keep it near the grow room, supposed to be great for folk that have Asthma and those that suffer from Hay-Fever as well
