It totally depends on the strain. Some strains seem to smell 20x more intense when flowering than others. In addition to the sheer intensity of the smell, some strains smell less like traditional marijuana and more like something less incriminating.

Fletch, it depends on the sort of ozone generator/ioniser used.

There's two basic kinds of O3 gens- high voltage corona discharge and ultraviolet. Corona ionisers work by maintaining a high voltage potential across a pair of electrodes of some sort. UV ionisers have special ionising fluorescent tubes.


one of my UV ionisers


Corona type ionisers DO create oxides of nitrogen which combine with water/humidity to create nitric acid, just as you note. Your very own home-made 'acid rain!' They also rapidly collect dust and dirt on their electrodes, requiring frequent cleaning (at least 1x week).

However, UV based O3 gens don't generate nitrogen oxides and don't collect as much dust.

I've seen some comments saying ionisers/ozone gens are useless for scent control.

Someone's been handing out some seriously bad advice.

Ionisers, whether corona or UV type, are highly effective at scent control, so effective that they will de-scent buds still on a plant if used in a flowering area. Mind you, I'm talking about serious ionisers, not the $30 'shower yourself with negative ions!!!' type toys.

Ionisers have the added benefit of killing mould spores and bacteria wafting in air. You'll often see UV ionisers in meat shops and at the entry to hospital emergency rooms for the purpose of killing stray pathogens.

Carbon filters are good for scent control, but must have their activated carbon filters replaced periodically. I've tried re-activating carbon filters by baking them, which does re-activate them to some extent, but the re-activated carbon only works about half as long as fresh carbon. However, baking won't remove accumulated dust from carbon filters. They also can not kill pathogens in air.

Here's 1000 words for ya Al..



And the propaganda from their website reads..

The Aironic AH 202 is a negative ion generator that works ideally in bedrooms, small offices and studies, and has an effective range of 28 sq metres. It measures 107mm wide x 112mm sits comfortably on any table (would you like a pillow Mr. Ionozer?) and weighs just 240 grams. This is the portable, compact, multi-purpose ioniser that restores the air. * Available at Dick Smith Electronics shops around Australia.

So seeing as it would have cost around $80 Aus (about $50 US?) I'm guessing it's slightly better than a "$30 'shower yourself with negative ions!!!' type toy." What's your opinion?

BTW, the dispenser of bad advice had the unit located in his grow cupboard but it was behind the extractor fan, so it couldn't do the buds any damage.

I'm a newbie, but I'm straying from Newbie Central temporarily to post a link to a news story related to the original topic of this thread, Dumb Mistakes...Video Player 2.0
If you have seen thousands of stories like this and didn't want another , sorry. I thought some of the things mentioned in the story might have been of some interest/amusement.

Depends on the strain. Some strains really stink the place up while others are fairly mild.

DUDE!!! wtf the cop in that movie said they were getting a contact hi from touching the plants!!!!!!!!! what a dip shit.

the only thing i get is stick fingers

his contact high was probably from touching a joint to his lips afterwards

Small scale growers don't really have much to worry about. So long as only aa very trusted few know you should be fine. The guys getting caught are usually growing on an industrial scale in residential areas. Electricity must be stolen, and this is the first part of evidence the police obtain. After this they will investigate the property and usually find what they expected to.

dumbass ppl who feel that they have a right to grow it or have it in their possession due to state law are the ones that are going to get caught. i see alot refer to “medical marijuana” on these boards. u all need to get it through your head. any weed is illegal in thd U.S. u all just need to shh and grow your tomatoes in peace like the happy little gardeners we are.
