Feminized
Critical Purple pairs Critical Mass vigor with Purple Afghani colour and aroma. Expect 7 to 9 weeks of flowering and yields around 500 to 600 g/mยฒ indoors. Keep veg light strong and use LST to flatten the canopy. Lower night temps in late flower to boost purple expression. Aim for 20-26ยฐC day temps and 12-15ยฐC night temps during colour phase. Use bloom nutrients with higher phosphorus and potassium after week four. Dry slowly at 18-20ยฐC and 50% RH, then cure for at least two weeks to deepen flavour. MasterSeeds offers feminized packs with clear grow notes for Canadian hobbyists and commercial growers.

Frequently Ask Questions
Everything you need to know about this strain.
Germinate on a moist paper towel, then transplant to light soil. Provide 18/6 light during veg and keep temps at 20-26ยฐC.
Harvest when trichomes show mostly cloudy with 10-30% amber. This balance preserves uplift while adding relaxation.
Lower night temps to 12-15ยฐC during late flower and reduce excess nitrogen. Maintain good nutrition and avoid stress spikes.
Use higher nitrogen in veg, then switch to bloom nutrients with increased phosphorus and potassium. Reduce nitrogen after week four of flower.
Use low-stress training and topping early to shape an even canopy. Apply SCROG for maximum light use and uniform buds.
Install a carbon filter and ensure steady exhaust airflow. Keep humidity stable and avoid plant stress during bloom.
Aim for 5.8 to 6.2 in soil and 5.5 to 6.0 in hydro. Test runoff regularly and adjust slowly.
Dry for 7 to 10 days at 18-20ยฐC and 50% RH, then jar with daily burps for two to four weeks. Extended cure up to eight weeks deepens flavour.
Spider mites and powdery mildew present common threats. Maintain airflow, inspect leaves, and use organic treatments early.
Yes. High THC offers strong relief for sleep issues and pain. Low CBD makes this strain less suited for CBD-focused protocols.
