Blue Velvet

Install extraction fans and passive intake to achieve several air exchanges per hour, and add horizontal air flow fans to keep air moving around the colas.

Water when the top few centimetres of medium feel dry; frequency depends on pot size and environment but typically every 2–4 days under moderate conditions.

Use a balanced vegetative feed followed by a bloom formula higher in phosphorus and potassium; reduce nitrogen late in flower to improve bud finish.

Control humidity with dehumidifiers, increase light penetration and airflow, and remove large fan leaves that block circulation around dense buds.

It is better for growers with some experience due to its susceptibility to mould and the need for active humidity control.

Begin low-stress training in early veg and top or FIM prior to flowering to encourage an even canopy and reduce internal shading.

Dry slowly to a 60% relative humidity target and cure in glass jars for at least two to four weeks for improved flavour and smoothness.

Yes, feminised seeds reduce the chance of male plants and are useful in limited spaces where every plant counts.

Yes, Blue Velvet adapts well to compact setups when kept short with training, but you must manage humidity and ventilation carefully in confined areas.

Inspect undersides of leaves for spider mites and aphids, check new growth weekly, and use preventive biocontrols or gentle insecticidal soaps if needed.
