The One

Use 20–30 litre pots for a balance of root space and manageability; bigger pots give larger yields but need more space and water management.

Aim for 40–50% RH in late flowering and increase ventilation to prevent mould; use dehumidifiers or extract fans if necessary.

Switch to 12/12 once plants reach desirable size in veg; with feminised photoperiod seeds this timing controls final height and yield.

Reduce nitrogen and increase phosphorus and potassium in weeks 5–8 of flowering to support bud density and resin production.

The One has average resistance but is vulnerable to bud rot in damp conditions, so maintain airflow and inspect regularly.

Yes, it responds well to organic feeding and compost teas, though you will need diligent pest and mould prevention practices.

Both topping and scrogging work well; use topping to control height and scrog to maximise light distribution and even canopy.

Use an inline fan with carbon filter, ensure fresh air intake, and create a slight negative pressure to remove humidity and odour efficiently.

Plan for good insulation, a controllable heating option for cool nights, and dehumidification to counter coastal damp; fit adjustable LED lights, an extractor fan with carbon filter, and space for oscillating fans to keep airflow even.

Harvest when trichomes are milky with some ambers, typically late September to early October in the UK, but monitor for autumn rains and potential mould risk.
