Allan Humphries: Welcome to Gardening Talkback on the ABC, Brian you've got a question for Allan Seale.
Talkback caller Brian: G'day, I want to know if it's possible to bonsai marijuana plants?
Allan Seale: (Goes silent and refuses to comment)
Allan Humphries: It's an unusual question Brian, what's the background to this?
Talkback caller Brian: I've got these marijuana plants in the back of the garden and they're getting a bit too tall and I'm afraid the copper can spot them over the fence. So I want to reduce the height, but not affect the yield.

Building a higher fence does not work looks like you are trying to hide something that is what happened here in Brisbane they had 5 kilo in freezer for personal use.
