About Secret Formula
Secret Formula combines Northern Lights vigour with Haze clarity to deliver a resilient, resinous plant suited to cooler maritime regions. The variety performs well both indoors and outdoors, offering a balanced effect, citrus-forward flavour and dependable yields when grown with attention to ventilation and shelter.
Secret Formula is an indica-dominant hybrid that balances mellow depth with a clear head. The structure favours compact buds with a resinous profile.
THC levels are reliably moderate to high, typically sitting between 18 and 22 percent. This potency gives a noticeable effect without overwhelming newer users.
CBD remains low but perceptible, around 0.5 to 1 percent. The low CBD keeps the experience predominantly psychoactive while offering a subtle balancing effect.
The lineage is Northern Lights x Haze, blending classic indica depth with sativa-derived lift. This cross brings resin production and aromatic complexity from both parents.
Seeds are offered in feminized photoperiod form to give predictable female crops. Growers control vegetative time to manage final plant size and yield.
Growing Secret Formula in a cool Scottish outdoor climate requires steady attention to ventilation and disease prevention. The strain suits growers with some experience who can manage humidity and secure plants against coastal winds in Fermanagh.

Yield is medium to high when plants receive regular feeding and good light exposure. Outdoor plants in sheltered spots can reach the upper range with careful canopy management.

It tolerates maritime conditions moderately well but benefits from a windbreak or planting behind hedging to reduce direct salt exposure.
Supplemental feeding helps, especially phosphorus and potassium during flowering, but avoid over-fertilising which can stress plants in cool soil.
Regular checks for aphids, spider mites and caterpillars are important, and prompt removal of affected leaves limits outbreaks.
Control stretch by timing the flip to flowering indoors or by topping and low-stress training before late summer outdoors.
SCROG and low-stress training work well to maximise light capture and reduce wind exposure for heavy colas.
