questions about ONA BLOCKS

i'm growing indoors and am in the flowering stage. in vegetation stage, there was a slight odor... when in the flowering stage, i'm assuming that the odor will get way stronger when the process continues..

i have two sharper image ionizers that emit O3 ozone, a rock salt lamp for natural neg. ions. and an ona block.

my question is about ONA blocks. it says it actually neutralizes the odors. what are all of your experiences with ONA blocks? i usually just open the lid for a minute or two as that is long enough for the room to really smell of ONA smell, the smell is nice, but then it has this industrial smell to it. can ONA be a giveaway just as easy as the smell we are trying to hide?

any comments i will appreciate. thank you

oh yeah, if anyone has any other cool ideas besides ona, ionizers, carbon filters to get rid of smell, i'm open to suggestions.

im stuck on this 1 too. cant afford £400 for carbon filter, and i cant find no ozone things around england nor a "neg ion wigg-ama-thing"

cool kamakazidude. maybe with two of us, someone will pop in and help us..

i too had the same problems with the ONA blocks an the industrial smell....
basically i ditched the blocks...and bought the carbon fliter off a mate for $490AUD
(A STEAL!)=) worth every cent.
but if your not doing that many plants, i personally have found ionizers efective enough...

thanks greenstick for your words. i plan to only use the ona sparingly. so would you think that a small desktop ionizer and shaper images large ionizers would be enough to help hide the odor of two plants growing? i plan to not do more than that at one time.
