Magnum

A loamy, well-aerated mix rich in compost and worm castings supports strong root development. Aim for good drainage to reduce the risk of root rot in damp conditions.

Maintain lower relative humidity in flowering to prevent mould; 40-50% is a good target. Use dehumidifiers or increased ventilation and prune the canopy to improve airflow.

Look for mostly cloudy trichomes with some ambers for a balanced effect and good resin. Harvest timing can vary by a week either way depending on desired potency and effect.

Provide 16-18 hours during veg and 12 hours during flower with sufficient intensity for dense bud formation. Keep light cycles consistent to avoid stress and potential hermaphroditism.

Magnum benefits from a steady, organic nutrient programme with a phosphorus boost in mid-flower. Avoid overfeeding which can build up salts and harm microbes in organic grows.

Pests can be an issue in damp climates; monitor for spider mites and aphids regularly. Introduce beneficial insects and use organic foliar sprays as a preventative measure.

Yes, but site selection is crucial; choose a sheltered, sunny spot with good drainage. Consider early varieties or secure cover to protect against late-season rain.

Use organic amendments like kelp and guano and maintain stable late-flower temperatures to boost terpene production. Gentle defoliation to expose bud sites to light also helps.

Feminised seeds remove the need to cull males, saving space and time for home growers. They make planning harvests and canopy management more straightforward.

Begin with a living soil mix full of compost, worm castings and mycorrhizal inoculants and feed lightly with compost teas. Keep the soil biome healthy and avoid synthetic fertilisers to maintain biological balance.
