Worried your sativa will be too wild, too slow, or too hard to manage?

Many growers hesitate to try pure sativas because they expect uncontrollable height, endless flowering times, and fragile plants that demand constant attention. You end up babying them, avoiding pruning, or even stashing the seeds in a drawer—afraid to mess up your grow.

Cum Laude changes that. Born from a triple hybridization of elite sativa cuttings, this feminized strain combines explosive growth with surprising resilience. It’s built for growers who want a true sativa rush without the stress—fast, stable, and ready to thrive whether you’re growing indoors or under the sun.

How to grow Cum Laude feminized seeds

Quick overview: Sativa-dominant feminized strain from Positronics · 70–80 day flowering · medium difficulty · ideal for sunny outdoor grows or controlled indoor setups.

Safe start: Germinate in a moist, dark environment at 22–25 °C. Transplant carefully when the taproot reaches ~1 cm. For a stronger root foundation, Root Juice BioBizz boosts early development and resilience.

Directed growth: Keep vegetative phase short to control height. Use 18/6 light cycle indoors. Opt for well-aerated soil and avoid over-fertilizing. BioBizz Pre-Mix provides balanced organic nutrition without stretching.

Efficient flowering: Switch to 12/12 light cycle. Support heavy colas with stakes. Maintain RH at 40–50% and ensure strong airflow. Apply Jungle Juice Bloom Advanced Nutrients during peak flowering for denser, resin-rich buds.

Harvest and refinement: Harvest when trichomes turn milky to slightly amber for a balanced high. Flush 7–10 days before harvest. Dry slowly at 18–22 °C and 50–60% RH, then cure for 2–4 weeks to enhance flavor.

Personal Experience of Pevgrow’s CEO (Alan)

When I first grew Cum Laude, I was skeptical—sativas usually stretch like crazy and take forever. But this one surprised me. I kept the veg phase short, just 3 weeks, and used soft LST to open up the canopy. The plant grew fast but stayed manageable, and the smell during flowering—wow—was like walking through a Mediterranean forest with hints of anise and earth. The high was clean, uplifting, and lasted for hours. The real game-changer? Not overfeeding it. I stuck to a light organic feed, and the terpene profile exploded. It’s now one of my go-to sativas for a creative boost without the anxiety.
