The Australia Institute have published a new paper "Drug Law Reform - Beyond Prohibition". It's based on a bunch of reaearch showing that prohibition of MJ (an other drugs) just isn't working. The bloke who wrote the paper was interviewed on Hack on Triple J today. The audio is not available yet but you can probably download it next week. Tak DP83___summary.pdf

I've grown a couple of times using a 40L rectangular tub under 400W with 2 plants. The plants were OK, but found that the roots took over the bucket and made it fairly hard to maintain. Next time I'll be using a control bucket.

I've grown lettuce before with very little sunlight. Check out the DPI site, it might have the information you're looking for.

As expansion said .. a 10kg (~22 pounds) plant !! Can someone point me to the seedbank where I can find some of those seeds :: Just love the way the media is abused in Aus. Tak

Courier Mail (Brisbane) Sunday 1 August 2004 A series of drug raids in southeast Queensland has uncovered sophisticated hydroponic cannabis "hot-houses" using thousands of dollars worth of equipment. Officer in charge of Queensland's drug investigative group Detective Inspector Brian Wilkins said an entire Gold Coast house was converted into a hydroponic operation. Some growers were spending up to $25,000 on equipment. Several southeast Queensland crime networks are believed to have established a virtual cottage industry of small-scale hydroponic cannabis producers in a series of homes, according to a recent report for the National Drug and Alcohol Research Centre. Det-Insp Wilkins said the hydroponic hothouses were becoming more elaborate with growers using industrial fans, air-conditioning, extractors, expensive lighting systems, water pumps, and high quality fertilisers. Hydroponic growers could produce significant quantities of cannabis within six to eight weeks with some plants yielding more than 10kg of cannabis each, Det-Insp Wilkins said. On July 15 Queensland police seized more than 400 cannabis plants from an upstairs section of a screen-printing factory at Andrews on the Gold Coast, charging a man, 65. Over the following few days a series of raids across Queensland resulted in police seizing hydroponic equipment from a property at Julatten, west of Port Douglas, and in the Brisbane suburbs of Mt Gravatt and Chappel Hill, as well as hydroponic cannabis plants growing in the Bundaberg and Rosedale areas. In March, three women were charged after police found 35kg of hydroponic cannabis hidden in two homes in a Southport street, Police said drug growers were renting private homes and converting them to cannabis hothouses. They were operating 24 hours a day, 7 days a week. The telltale signs of a [hothouse] included humming noises from extractor fans and water pups, smells and fertilisers, hoses through windows, blacked-out windows and lights running non-stop.

Do you have an existing air con in the house? Is it a fully ducted unit (ie. has holes in the roof for cool/hot air and a central return air inlet (where the filter is located)? I have ducted air I don't think it would be very suited for temp control in a growroom. The air coming into the room needs to flow through the house and back into the return valve to be re-cooled/re-heated. As each room doesn't have it's own zone (ie. a number of rooms are connected to a single feed pipe) if one door is shut, then the room doesn't cool or heat as the pressure from this room just provides more airflow to other rooms in the zone. Once the door in the room is open (even just a little) the ducted air keeps the temp nice all the time. I would guess that if you left your growroom door open to keep it cool with the ducted air, the smell would get right through your house. Sorry if my explanation doesn't make sense, can probably knock together a diagram of how my system works if it helds.

Has anyone tried using the DrDAQ to monitor a growroom? The software for it looks pretty easy to work. They come with (onboard) temp and light sensor, and can handle pH and two other probes. I was thinking of putitng the unit near the entrance to my exhaust vent so it can monitor temp of air on the way out, and the light sensor can tell me if the light has come on as expected. Was also thinking of maybe a temp + pH for the res tank also. Leaves one spare for something else later (maybe EC). Think it is a bit sus checking on my room regularly so though this might be useful to check things out without a visit - don't want to waste money though if someone has had a bad time with one of these before.
