Facts. Police attend Sam's flat for an unrelated reason and see a few plants in a cupboard. Sam, 35, says they are for his own use. He has no previous record.

What the law says. Cultivation (MDA s.6(2)) has a maximum of 14 years, with an offence range from a Band A fine to 8 years.[1] No warning scheme covers cultivation: the cannabis warning applies to possession only.[13] If convicted, a credible own-use account puts Sam in the lesser role, and the plant count is compared with the indicative 7-plant (Category 4) level. Below that, the court adjusts downwards within the Category 4 lesser range (Band B fine to medium CO), but 7 is not a permitted number.[1]

If…Then…
Very few plants, first time, credible own use, cooperationPolice may consider a caution or conditional caution, or charge → fine / low-level CO
Around 7 plantsCat 4 lesser starting point: low-level CO
Repeat grow after a previous caution or convictionCharge likely; previous record is statutory aggravation
Lights, fans or hydroponics in a dedicated roomAggravation ("specialist equipment" / ongoing operation)
Any sign of sellingSignificant role → custody range

Other consequences. Forfeiture of equipment (MDA s.27); a landlord may seek possession (Scenario 9); home insurance may be invalidated.

Myth. "Personal-use growing has a 5-year maximum." The cultivation maximum is 14 years; 5 years is the possession maximum.[1][2]

Rights. Do not accept a caution before taking legal advice: it is an admission and goes on your record.
