Hey basically what the title says.. Has anyone used one during their grow? Or possibley as their main odour control? I was just wondering if with a one plant grow, using a largish 30cm long air ionizer (heaven fresh hf-100 - uk) would be sufficient during the majority of the grow, if situated within the grow box at the top next to the exhaust fans. It wouldnt effect the plants in anyway obviously, they are just negative ions.. It would increase the stealthlyness of the grow massively, no whoosing from the fans, and hopefully no smell.. If needed i will be using a few diy carbon filters, but ill get this anyway and see how long it will prevent the smell from leaking. For £20 i think its just worth trying... Opinions?
