Cultivation Guide for Cactus Jack
Select the cultivation location
Cactus Jack can be grown both indoors and outdoors. Indoors, you have control over light and climate, while outdoors it thrives best in a warm, sunny climate with low humidity.
Prepare the soil
Use well-aerated, nutrient-rich soil with a pH between 6.0 and 7.0. Organic additives such as worm compost or bat guano support growth and improve the plant's resilience.
Sow the seeds or plant the seedlings
Germinate the seeds in moist paper towels or water until roots are visible. Then plant them about 1–2 cm deep in the prepared soil.
Ensure proper lighting conditions
Cactus Jack needs plenty of light to reach its full potency. Indoors, LED or HPS lamps are ideal, with an 18/6-hour light cycle during the vegetative stage and 12/12 during the flowering stage. Outdoors, the plant should receive at least 8 hours of direct sunlight per day.
Monitor temperature and humidity
Keep daytime temperatures between 22–28 °C and do not let them drop below 18 °C at night. Humidity should be 50–60% during the vegetative stage and reduced to 40–50% during flowering to prevent mold.
Water regularly
Water the plants evenly, but avoid waterlogging. Wait until the top layer of soil is dry before watering again. Use filtered or pH-neutral water whenever possible to prevent nutrient lockout.
Optimize nutrient supply
During the vegetative stage, Cactus Jack needs nitrogen-rich fertilizers. In the flowering stage, reduce nitrogen and increase phosphorus and potassium to promote flower development.
Train the plants (optional)
Use low-stress training (LST) or other techniques to control growth and maximize yields. This ensures light is distributed evenly to all Flowers.
Pay attention to the flowering time
Cactus Jack has a flowering period of about 9–10 weeks. Check the trichomes with a magnifying glass—when they are milky white, it is the optimal time to harvest.
Harvest and dry the Flowers
Carefully cut the Flowers and hang them in a well-ventilated, dark room with a humidity of about 50%. After 7–14 days, they are ready for curing to develop their full aroma.
