Keep an eye out for slugs, aphids and spider mites; inspect plants regularly and use biological controls or gentle soaps where possible.

Yes, low-stress training or a modest screen of green can increase light penetration and boost yields without excessive height growth.

For high humidity cannabis cultivation focus on dehumidification, increasing airflow, pruning for airflow, and timing harvests to avoid prolonged wet periods; in small grows a dehumidifier and extractor fan are essential.

Harvest when trichomes are milky with some amber present and when weather forecasts show a dry window to avoid mould during bud drying.

It responds well to standard organic or mineral feeds with attention to calcium, magnesium and micronutrients to prevent deficiencies during rapid growth.
