Shark Shock

Shark Shock has decent natural vigour but dense buds are vulnerable in prolonged damp. Vigilant air circulation and early harvest planning reduce rot risk.

Harden plants off after the last frosts and when night temperatures consistently exceed 7–10°C. In Cambridge I typically move them out in late May to early June, depending on the year.

Switch to a bloom formula with lower nitrogen and higher phosphorus and potassium once flowering starts. Keep EC/PPM moderate and avoid overfeeding to reduce stretch and nutrient lockout.

Improve airflow, remove lower foliage to open the canopy and maintain RH below 55% during late flowering where possible. For high humidity cannabis cultivation focus on dehumidification indoors and sheltered, sun-exposed sites outdoors.

Selective defoliation can improve light penetration and airflow but avoid heavy leaf stripping. Remove only shaded leaves and do so early in flowering when plants can recover.

A 7–14 day flush is typical to help clear excess nutrients and improve smoke quality. Monitor plant condition and trichome clarity rather than relying solely on flushing duration.

Yes, low-stress training and topping produce multiple strong colas and can boost yields indoors. Outdoors in Cambridge, combine LST with a light defoliation to manage canopy shape safely.

Aphids, spider mites and caterpillars are common threats in outdoor UK grows. Regular inspections and prompt use of biological controls or organic treatments keep infestations manageable.

Aim for majority cloudy trichomes with some amber for a sedative effect and harvest before persistent autumn rain. In unpredictable seasons, harvest a little early rather than risking mould.

Excess light or heat can cause leaf bleached tips and speed up flowering unevenly. Match light intensity to canopy size and provide recovery periods to prevent stress-related yield loss.
