White Iverson

Plant after the last heavy frosts and when soil temperatures are reliably above 10°C, usually late May in many parts of the UK.

It tolerates some maritime influence but heavy salt spray will stress foliage; position plants behind hedges or use temporary windbreaks for protection.

Use staking, tie branches low, create windbreaks and choose a sheltered microclimate to reduce mechanical damage.

Use a balanced NPK regime early on then higher phosphorus and potassium during flowering, and supplement with silica to improve stem strength.

From seed expect around four to five months outdoors in cool climates, depending on local warmth and the specific phenotypes.

Yes, feminised seeds reduce the chance of male plants and maximise productive use of limited outdoor space.

Increase airflow, prune lower foliage, avoid dense canopies and harvest promptly if wet weather is forecast.

It is relatively suitable for short season outdoor cannabis growing because of its eight to nine week flowering time, but success depends on local microclimate and early veg growth.

Flush with plain water for the final ten to fourteen days before harvest to improve smoke quality and reduce residual nutrients.

Use a loupe to check trichomes; harvest when most are cloudy with some amber for a balanced effect.
