Jack Frost, a balanced hybrid, delivers a symphony of effects that elevate mood and foster relaxation while injecting a burst of energy. Its genetic lineage combines the best traits of Jack Herer, White Widow, and Northern Lights #5, resulting in a versatile strain suitable for various conditions.
Users experience a happy and euphoric high, often feeling uplifted and reinvigorated. The flavor profile is a refreshing mix of pine and citrus with an earthy undertone, making it a delightful choice for those battling stress, depression, and anxiety.
White Widow, a balanced hybrid first bred in the Netherlands by Green House Seeds, is renowned for its potent resin production.
This strain is a cross between a Brazilian sativa landrace and a resin-heavy South Indian indica.
White Widow has graced every Dutch coffee shop menu since its birth in the 1990s.
Its buds are white with crystal resin, warning of the potent effects to come.
A powerful burst of euphoria and energy breaks through immediately, stimulating both conversation and creativity.
White Widow's genetics have given rise to many other legends like White Russian, White Rhino, and Blue Widow.
Still, many growers prefer cultivation of the original White Widow, which flowers in about 60 days indoors.
Northern Lights stands among the most famous strains of all time, a pure indica cherished for its resinous buds, fast flowering, and resilience during growth.
It is believed to have first sprouted near Seattle, Washington, but was propagated out of Holland after 1985 at what is now Sensi Seeds.
Pungently sweet, spicy aromas radiate from the crystal-coated buds, which sometimes reveal themselves in hues of purple.
Northern Lights' psychoactive effects settle in firmly throughout the body, relaxing muscles and pacifying the mind in dreamy euphoria.
Comfortable laziness allows patients to relieve pain and sleeplessness, while its mellow contentment roots out depression and stress.
Several different Northern Lights phenotypes circulate the market, but Sensi Seeds recommends a general indoor flowering time of 45 to 50 days.
Jack Herer is a sativa-dominant cannabis strain that has gained as much renown as its namesake, the marijuana activist and author of "The Emperor Wears No Clothes."
Combining a Haze hybrid with a Northern Lights #5 and Shiva Skunk cross, Sensi Seeds created Jack Herer hoping to capture both cerebral elevation and heavy resin production.
Its rich genetic background gives rise to several different variations of Jack Herer, each phenotype bearing its own features and effects.
However, consumers typically describe this 55% sativa hybrid as blissful, clear-headed, and creative.
Jack Herer was created in the Netherlands in the mid-1990s, where it was later distributed by Dutch pharmacies as a recognized medical-grade strain.
Since then, the spicy, pine-scented sativa has taken home numerous awards for its quality and potency.
Many breeders have attempted to cultivate this staple strain themselves in sunny or Mediterranean climates, and indoor growers should wait 50 to 70 days for Jack Herer to flower.
Jack Frost thrives in a spacious environment that allows for its bushy growth and lateral branching. A room or tent should be at least 5 feet in height to accommodate the plant's stature and provide ample space for air circulation. Reflective walls are beneficial to distribute light evenly and maximize photosynthesis.
For Jack Frost, full-spectrum LED lights are optimal due to their efficiency and lower heat output. Positioning lights 18-24 inches from the canopy encourages robust growth. A 600W HPS can also be used, especially during the flowering phase, to promote dense bud development.
Proper ventilation is crucial for Jack Frost to prevent mold and mildew. An exhaust fan combined with passive intake vents facilitates a continuous flow of fresh air. Supplementing with a CO2 system can significantly boost growth and yield, as this strain responds well to increased carbon dioxide levels.
Jack Frost prefers a temperature range of 68-80°F with a slight drop at night. Humidity should be maintained at 40-50% during the flowering stage to prevent bud rot. A dehumidifier and air conditioner are essential tools to maintain these conditions.
Hydroponics can accelerate Jack Frost's growth, offering precise nutrient control and potentially larger yields. However, soil cultivation can enhance the strain's pine and citrus flavors. Organic super soil, rich in nutrients, is ideal for this strain to develop its full aromatic profile.
As Jack Frost transitions to the vegetative stage, adjust the light schedule to 18 hours of light and 6 hours of darkness to promote growth. Implement plant training techniques such as topping to create a bushier canopy and low-stress training (LST) to expose more bud sites to light, increasing yield potential.
Regular pruning is essential to remove unnecessary foliage and direct the plant's energy to top growth. Defoliation should be performed to enhance light penetration and air circulation within the canopy. This process also helps in the prevention of mold and pests. Monitor the plant's health and remove any yellowing or dead leaves to maintain optimal growth.
To induce flowering in Jack Frost, change the light schedule to 12 hours of light and 12 hours of darkness. This mimics the natural decrease in daylight hours and triggers the plant to enter the flowering phase. Additionally, ensure the environment is stable with appropriate humidity and temperature levels to support flower development.
During the flowering phase, Jack Frost requires nutrients with higher phosphorus and potassium levels to support bud formation. Adjust the feeding schedule to include bloom-specific nutrients and reduce nitrogen intake. Consistent feeding will support the development of dense, resinous buds characteristic of this strain.

Jack Frost plants are typically ready for harvest when 50-70% of the pistils have darkened and curled in. Trichomes should be inspected with a magnifying glass; harvest time is ideal when most trichomes are milky white with some amber. Clear trichomes indicate the plant is not yet fully mature, while too many amber trichomes suggest the plant is past its peak.
Begin by sterilizing cutting tools to prevent infection. Cut the main stem at the base for a full plant harvest, or snip branches individually for a selective approach. Trim away large fan leaves and smaller sugar leaves to expose the buds. Make precise cuts to retain the bud structure and trichomes, which house the cannabinoids and terpenes.
Hang the trimmed buds upside down in a controlled environment with temperatures around 60-70°F and humidity levels at 45-55%. Ensure good air circulation without direct airflow on the buds to prevent uneven drying. After 7-10 days, when stems snap rather than bend, the drying process is complete. Cure the buds by placing them in airtight containers, opening them several times a day for the first week to release moisture and replenish oxygen. Continue this process for 2-4 weeks to enhance the flavor and potency of the Jack Frost strain.
Store cured buds in airtight containers made of dark glass to block light, which can degrade cannabinoids and terpenes. Keep the containers in a cool, dark place to maintain freshness and quality. Monitor humidity within the containers, maintaining it at 59-63% to prevent mold growth and preserve the buds' integrity.
Selecting an optimal location is critical for the successful cultivation of Jack Frost. The area must receive ample sunlight, as cannabis plants require significant light for photosynthesis and growth. Protection from strong winds is also essential to prevent physical damage to the plants and to reduce water loss through evapotranspiration. Additionally, privacy is a key consideration to safeguard your crop from theft or unwanted attention, complying with local regulations regarding cannabis cultivation.
Cannabis thrives in soil with a pH level between 6.0 and 7.0, which allows for optimal nutrient uptake. The ideal soil texture is loamy, offering a balance of drainage and water retention, and is rich in organic matter to support robust plant growth. To prepare the site, amend the soil with compost, worm castings, and other organic nutrients to improve fertility. Regular testing and adjustment of soil conditions are necessary to maintain an optimal growing environment for Jack Frost.
Consistent access to water is vital for cannabis plants, which can be particularly water-hungry during the vegetative and flowering stages. If natural rainfall is insufficient, setting up an irrigation system becomes imperative to deliver water directly to the plant roots. This system should be reliable and adjustable to meet the changing water needs of Jack Frost throughout its growth cycle. Proper water management helps prevent stress on the plants, which can impact their development and the potency of the final product.
Jack Frost is best planted outdoors after the last frost date to avoid cold damage. In temperate climates, this typically falls between late April and early May. For warmer regions, planting can occur as early as March. Monitor local weather forecasts to adjust planting times, ensuring that soil temperatures have consistently reached at least 60°F (15°C) for optimal root development.
Transition seedlings or clones to outdoor conditions by gradually exposing them to outside temperatures over a week, a process known as hardening off. Space plants 2 to 3 feet apart to allow for adequate airflow and growth. Upon transferring, water the plants deeply to establish roots, avoiding over-saturation, and maintain a consistent watering schedule during the early growth stages.
Shield young Jack Frost plants from pests and animals with physical barriers such as cloches or fencing. In regions prone to extreme weather, employ row covers to moderate temperature fluctuations and protect from heavy rain or hail. Regular inspections for signs of stress or infestation will allow for timely interventions, preserving plant health.
Jack Frost requires a balanced feeding regimen that adapts to its growth stages. During the vegetative phase, focus on nitrogen-rich fertilizers to support foliage development. As the plant transitions to flowering, gradually shift to phosphorus and potassium-heavy nutrients to promote robust bud formation. Outdoor growers should perform soil tests to determine specific nutrient needs and adjust feedings accordingly. Consistent monitoring of pH levels is critical to nutrient uptake, aiming for a soil pH between 6.0 and 7.0.
For organic pest management, neem oil and insecticidal soaps are effective against common cannabis pests like spider mites and aphids. Introducing beneficial insects such as ladybugs can provide natural pest control. For diseases like powdery mildew, a baking soda and water mixture can act as a preventative foliar spray. Chemical solutions should be a last resort due to potential residue; however, miticides and fungicides can be used following strict adherence to application guidelines to minimize harm to the plant and environment.
Pruning Jack Frost involves removing lower growth that receives little light to redirect energy to the upper canopy. Topping, cutting the main stem above a node, encourages bushier growth and more colas. Trellising supports the plant's structure and maximizes light penetration. Low-stress training, gently bending and securing branches, improves air circulation and light exposure without significant stress to the plant. These techniques, when applied correctly, can significantly increase yield and overall plant health.
To determine the optimal harvest time for Jack Frost, monitor the trichomes and pistils on the buds. Trichomes should transition from clear to a milky white color, with some turning amber for a more sedative effect. Pistils will darken and curl inward, indicating maturity. Use a magnifying glass or jeweler's loupe to inspect these indicators closely for precise timing.
Efficient harvesting of Jack Frost involves clean, sharp scissors to cut the branches. Remove large fan leaves to access the buds more easily. Cut the branches into manageable sections, trimming away excess leaf material to enhance the buds' appearance and concentrate the cannabinoids. Work in sections to maintain control over the process, reducing the risk of damaging the plant and preserving its potency.
Drying and curing Jack Frost outdoors or in non-controlled environments requires attention to humidity and temperature. Hang the trimmed branches upside down in a space with good air circulation, away from direct sunlight. Aim for a consistent temperature around 60-70°F (15-21°C) and humidity levels between 45-55%. This environment will facilitate a slow, even drying process over 7-14 days. After drying, place the buds in airtight containers, opening them daily for the first week to release moisture and prevent mold. Continue curing for 2-4 weeks to develop flavor and potency.
Store Jack Frost buds in airtight containers made of glass or food-grade materials to maintain their potency. Keep the containers in a cool, dark place to prevent degradation from light and heat. Check periodically for signs of mold or moisture, and use desiccant packs if necessary to control humidity. Proper storage will preserve the happy, euphoric, and uplifting effects along with the pine, citrus, and earthy flavors of the strain.
