SINGAPORE — A drug abuser who grew two pots of cannabis plant for over a month in an improvised greenhouse he created inside his Yishun HDB flat was on Wednesday (25 March) jailed for four years.

Artamu Ibrahim, a 45-year-old Singaporean, pleaded guilty to one charge each of drug cultivation, drug possession and drug consumption.

Another count of having drug taking utensils was considered in sentencing.

Found out how to cultivate cannabis online

Officers from the Central Narcotics Bureau raided Artamu’s home on 9 September last year after Immigration and Checkpoints Authority officers detected a suspected drug taking tool at SingPost Centre’s Parcel Post Section.

Inside his Yishun flat, the anti-narcotics officers found two small containers containing a total of 4.98g of vegetable matter on a table in the master bedroom. The vegetable matter was later found to be cannabis.

They also found two pots of cannabis in a makeshift greenhouse, along with numerous instruments and reagents used for cannabis cultivation, in another room. The pots weighed 1.83g and 49.7g.

Artamu admitted to cultivating the cannabis plants, which were about 45 days old. He found out how to cultivate the plants online, and read up on the amount of water, humidity level and temperature required for the plants.

Used electric timer to control fans, ventilator

Inside the tent that he built, Artamu used light bulbs, a spotlight and LED lights to boost the plants’ growth. He also used fans to control the temperature inside the tent, alongside a ventilator and a humidifier.

And he used pH agents to control the acidity of the water for the plants, and a weighing scale to measure the amount of pH agents.

So elaborate was his set-up that Artamu used an electric timer to maintain the amount of time the fans, the ventilator and the lights were switched on and off.

“He had measured the humidity, temperature and soil wetness in the grow tent and the pH level of water using two humidity meters, a thermometer, a 3-in-1 meter and pH readers,” said Deputy Public Prosecutor Lu Yiwei.

“He had also used an IP camera, which was linked to his mobile phone, to monitor the meters and the cannabis plants when he was not home,” the prosecutor added.

After his arrest, Artamu provide urine samples, which tested positive for cannabis.

In 2006, he was jailed for 10 months for consuming cannabis.

For cultivating cannabis, Artamu could have been punished with a jail term of between three and 20 years, or a fine of between $5,000 and $40,000, or both.

He will begin his prison sentence on 6 April.
