Chemdawg Grow Timeline
Chemdawg Seeds & Genetics
Genetics: Unknown (believed OG Kush ancestor) | Breeder: Unknown (Massachusetts, early 1990s) | Type: Hybrid (Indica-dominant)
Chemdawg has mysterious origins - believed to have emerged from the New England underground in the early 1990s. Its genetics are the foundation of OG Kush, Sour Diesel and Gorilla Glue #4. Seeds are available feminised from multiple breeders. The strain is potent (20-25% THC) and highly aromatic. For growing basics, visit our beginner cannabis growing guide.
Indoor vs Outdoor Growing Chemdawg
Chemdawg performs well indoors under HPS or LED. Its branchy structure responds excellently to SCROG - see our SCROG guide. Top at the 4th-5th node and implement netting 2-3 weeks into veg. Intense aroma during flowering requires a quality carbon filter. Outdoors, suits warm dry climates finishing in mid-to-late October. Our outdoor growing guide covers site selection.
Nutrients & Feeding for Chemdawg
Chemdawg is a moderate-to-heavy feeder with tendency to show nutrient burn if EC is too high. Start at 75% of recommended doses. Nitrogen-dominant in veg at EC 1.2-1.8. CalMag important throughout. Flush 10-14 days before harvest. Full schedule in our nutrients guide.
Common Problems & Solutions
Sensitive to humidity - bud rot risk elevated given its dense cola structure. Maintain RH below 45% from week 6 and ensure strong airflow. Overfeeding causes rapid tip burn. Some phenotypes sensitive to pH fluctuations - maintain 6.0-7.0 in soil. Check our pH guide for troubleshooting.
Harvest, Drying & Curing Chemdawg
Ready when 70-80% of trichomes are milky white with 15-25% amber. Intense diesel aroma peaks at harvest. Trim carefully - the sticky resin coats everything. Dry 10-14 days at 18-21C. Cure 4-6 weeks in glass jars. Full instructions in our harvest guide.
