Baby Blu

Use 18/6 for veg and switch to 12/12 for flowering; consistent dark periods are important for reliable flowering.

Maintain good airflow, control humidity below 50–55% in late flowering and remove dense fan leaves to improve circulation.

Standard three-stage feeds work well with slightly higher phosphorus and potassium in flowering and moderate nitrogen in vegetative growth.

Harvest when trichomes are mostly cloudy with some ambers, typically early to mid autumn in a UK season.

Selective pruning and topping improve light penetration and yield, especially under indoor conditions.

Dry slowly over 7–10 days at 18–21°C with 45–55% RH, then cure for at least two weeks to improve flavour and smoothness.

Yes, it tolerates moderate temperature swings but prolonged cold and wet conditions late in the season increase risk of mould.

Baby Blu adapts well to SCROG because of its branching and cola structure; SOG is possible with many clones but requires more plants.

Use preventative measures like sticky traps and biological controls, inspect regularly and treat early with approved measures to keep populations down.

Using controlled climate cannabis growing—such as a greenhouse with dehumidification—lets you stabilise RH and temperature, which reduces mould risk and improves resin development.
