About Gorilla Glue #4

Gorilla Glue #4 is a high-resin hybrid bred for potency and thick, resinous flowers. The strain delivers fast-acting euphoria that transitions into deep physical relaxation and suits experienced users seeking strong effects.

Grow Difficulty:

Growing Gorilla Glue #4 in humid greenhouse conditions demands active mould prevention and careful ventilation. The plant is otherwise robust but benefits from experienced canopy management and dehumidification.

Flowering Time:

Flowering normally finishes in 8–9 weeks under controlled light cycles. Outdoor growers can expect a harvest around early to mid October in the UK.

Yield:

Yield potential is high with proper feeding and pest control, producing dense, resinous buds. In a greenhouse in Carmarthenshire, individual plants can deliver substantial harvests when trained well.

Height:

Plants tend to reach a medium to tall stature with sturdy main colas. Branching is vigorous, and training methods like SCROG work well to control height.

Environment:

Indoors, Gorilla Glue #4 responds well to controlled environments and yields heavily when trained. Outdoors in Carmarthenshire the strain can mature into tall, resin-coated plants and benefit from sheltering from persistent rain.

Climate:

In Carmarthenshire, humid greenhouse conditions require strict humidity control and airflow to prevent bud rot. Maintain 40–50% relative humidity during flowering and provide frequent air exchange to protect floral integrity.

Q
How can I maximise bud sites without increasing height?
A
Verified answer
Use low-stress training and a SCROG screen to spread the canopy and create many even bud sites while controlling vertical growth.

Q
What is an effective flush schedule for this strain?
A

Flush with plain water for 7–14 days before harvest depending on nutrient strength to reduce harshness in the final smoke.
Common question Posted by Urbanseedbank Answered
Q
Should I top Gorilla Glue #4 or just train?
A
Verified answer
Topping once early and following with training gives a good balance of main colas and lateral growth; avoid excessive topping late in veg.

Q
Which drying humidity is best for dense GG4 buds?
