About Oppenheimer

Oppenheimer is an indica-dominant hybrid that performs well in protected environments and tolerates the challenges of a moist western coastal climate. It offers medium to high yields, dense resinous buds and a sedative, relaxing effect profile suitable for evening use.

Grow Difficulty:

Under a moist western coastal climate Oppenheimer is best suited to growers with some experience. It tolerates humidity but requires good ventilation and careful mould prevention.

Flowering Time:

Flowering finishes in about eight to nine weeks under proper conditions. Growers should monitor trichome development rather than strict calendar dates.

Yield:

Yields are medium to high in a protected greenhouse and can be consistent outdoors in favourable spots. With proper training and feeding a greenhouse in Down can push production further.

Height:

Plants reach a medium-tall stature, often between one and one point eight metres. The structure features sturdy main colas and a compact side branch pattern.

Environment:

In Down growers commonly run Oppenheimer in greenhouses to stabilise conditions. In Down outdoor cultivation can work if plants are given wind protection and a dry micro-site.

Climate:

Growing Oppenheimer in Down demands strict humidity control because of the moist western coastal climate. Greenhouse ventilation, dehumidification and timely canopy management will keep mould risks low.

A little stem rot on the lowest colas one year; solved by pruning and moving plants to a drier bench area in the greenhouse.
