Catfish

Use the paper towel or direct-soil method and keep temperatures around 20–25°C until taproots appear, then transplant carefully to avoid root shock.

Start with a balanced vegetative feed and switch to a bloom formula higher in phosphorus during week 3 of flowering, tapering nitrogen down in later weeks.

Control humidity with fans and dehumidifiers, space plants to improve airflow, and remove lower foliage to reduce damp microclimates around bud zones.

Yes; low-stress training and topping encourage an even canopy and better light penetration, increasing usable bud sites without excessive height.

Harvest when trichomes show a mix of cloudy and amber for balanced effects, usually late September to early October in most UK microclimates.

Yes; outdoor cannabis cultivation suits Catfish if you pick a sheltered, sunny spot and plan for disease prevention given Sheffield's variable weather.

Dry slowly for 7–10 days at 18–21°C and 45–55% RH, then cure in jars with daily burping for the first two weeks and continue for at least a month for best flavour.

Aphids, spider mites and thrips are common; use integrated pest management—predatory insects, neem oil and careful hygiene—to keep populations down.

Many growers reduce feed and flush with plain water one to two weeks before harvest to improve smoke quality, but follow your nutrient system guidance.

Stiff, woody stems can indicate maturity but always check trichome development and pistil colour for accurate harvest timing.
