Critical Blue

Use 18/6 during veg and switch to 12/12 for flowering. Maintain a stable dark period to avoid stress and hermaphroditism.

Yes, full-spectrum LEDs with strong PAR output during flowering produce dense buds. Keep panels at the recommended distance to avoid light burn and ensure even canopy coverage.

It prefers moderate humidity in vegetative stages and lower humidity during late flowering to prevent bud rot. Good airflow and dehumidification are essential in damp climates.

Standard cannabis NPK feeding works well: higher nitrogen in veg and increased phosphorus and potassium in bloom. Avoid overfeeding; flush lightly before harvest if excess salts build up.

Check trichomes for mostly cloudy with some amber for balanced effects. Typical indoor harvest falls between seven and nine weeks of flowering.

Dry slowly in a dark, ventilated room until stems snap then cure in jars at 60–65% humidity. Burp jars daily for the first two weeks to stabilise moisture and flavours.

Yes, its dense buds can attract botrytis in wet conditions. Plant in a well-ventilated, elevated spot and consider early-season fungicide if your region is persistently rainy.

Absolutely — indoor LED cannabis cultivation is an efficient way to control temperature and humidity, which benefits Critical Blue in variable climates. Use quality LEDs with adequate PPFD and manage height with pruning or training.

Mainline, SCROG or topping work well to create an even canopy and increase bud sites. Keep training early to reduce stress during flowering.

Both media produce good results; soil is more forgiving for intermediate growers while hydroponics can boost growth and yield if you manage EC and pH closely. Choose based on experience and resource availability.
