(this story is not true and im just speaking hypothetically.....)

I think the most important thing is dont buy a scales or baggies, dont attract attention to ur house and if u do get arrested act as stupid, worried,anxious and apologetic as possible (bit of crying doesnt hurt either). My m8 got brought in for 6 plants (he's a pretty experienced grower) they asked him how much did u get off the plants? he said " i think it was 2 VIDEO BOXES of leaves and one video box of buds, but i only smoked the leafs cos the buds didnt burn properly". the copper replied '' ye, i think u have to dry them out first".
Take ur chances mate, its your human right and the government shouldnt be allowed to tell u what u can and cant smoke. I think the pros outweigh the cons with risking a grow.
