Dark Knight

Maintain 20–24°C by day and allow a 3–5°C drop at night; humidity around 40–50% during late flowering helps prevent mould and preserves trichomes.

From seed to harvest expect roughly 12–14 weeks indoors including veg; extend slightly if you run a longer veg period to increase yields.

Yes, Dark Knight suits SCROG well due to its compact structure and large central cola, while SOG can work if you use many small plants and strong lighting.

Reduce nitrogen and increase phosphorus and potassium as flowering progresses, and monitor EC to avoid salt buildup; flush lightly before harvest if residues are a concern.

Improve airflow, keep late-season humidity down, remove lower shading foliage, and consider using dehumidifiers indoors or timed ventilation outdoors if possible.

Harvest when most trichomes are milky with some amber for a balance of potency and flavour; leave an extra few days for fuller terpene development if conditions are stable.

You can grow it outdoors near Inverness, but expect a shorter season and consider polytunnels or greenhouses to protect from rain and cool nights.

Use integrated pest management: sticky traps, predatory insects, regular leaf inspections and neem or bacillus thuringiensis treatments as required; avoid high-residue chemicals.

A light flush can improve smoke quality if you've used higher-salt feeds, but balance flushing with plant health to avoid stressing buds in the final week or two.

Look for UK-based resources that cover ventilation, humidity control, insulation and light schedules suited to small rooms; local growers' forums and community groups around Inverness often share practical tips for equipment and layouts.
