Frequently Ask Questions
Everything you need to know about this strain.
Use 18/6 for veg and 12/12 for flower. Aim for strong, consistent PAR levels in flower.
Keep RH under 50 percent in late flower and maintain steady airflow. Remove dense fan leaves to improve bud circulation.
Start a mild flush one to two weeks before harvest. Stop heavy feeding and use plain water to clear salts.
Moderate nitrogen in veg and higher phosphorus and potassium in flower. Avoid nutrient spikes that stress resin production.
Use slightly lower night temperatures and avoid excess nitrogen in late flower. Add bloom boosters with PK late in flowering.
Yes. Low-stress training and light topping produce even canopy and higher yields. Keep training early to avoid stress in flower.
Spider mites and bud rot pose the main risks in dense canopies. Inspect plants weekly and treat quickly at first sign of infestation.
Harvest in late September to early October in temperate zones. Monitor trichomes for desired amber to clear ratio.
Cure for at least two to four weeks in airtight jars with daily burping early on. Longer cures improve smoothness and flavour.
Use a well-draining soil with good organic content and stable pH around 6.0 to 6.5. Avoid heavy compaction and waterlogging.
