How to Grow Runtz x Layer Cake for Maximum Yield and Flavor

Starting strong and staying steady is key with this forgiving hybrid. It thrives in controlled environments but handles outdoor conditions like a champ.

1. Germinate seeds in a moist paper towel at 21–32°C (70–90°F); transfer once the taproot reaches 5–10 mm (0.2–0.4 in).

2. Plant in 11–20 L pots with well-aerated soil or coco; Barneys Farm seeds respond best to stable root zones.

3. Use 18/6 light cycle in veg; switch to 12/12 to trigger flowering after 3–4 weeks.

4. Apply gentle LST early to shape the plant; avoid topping due to its compact nature.

5. Monitor pH at 6.0–6.5 (soil) or 5.8–6.2 (coco); maintain EC progressive with growth stage.

6. In flowering, reduce humidity to 40–50% and boost airflow to protect dense buds from mold.

7. Harvest in 65–70 days when trichomes turn milky to amber for peak potency and flavor.

Keep your Runtz x Layer Cake plants healthy by maintaining clean grow spaces and consistent climate control. During flowering, prune lower, shaded branches to focus energy on top colas and improve airflow. After harvest, dry slowly at 18–22°C (64–72°F) and 50–60% humidity for 10–14 days, then cure in glass jars for 2–4 weeks to enhance flavor and smoothness.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Runtz x Layer Cake in my 1.20 x 1.20 m (4 x 4 ft) tent with a 600W LED, and damn—this strain impressed me from day one. Minimal stretch, bushy structure, and those buds? Frosty as hell by week 6. I used a simple soil mix with Royal Queen Seeds additives and went heavy on PK in week 4. Yield was 720 g off one plant—dense, sticky, and purple as a grape soda. The high hit fast: creative, then deeply relaxing. My only tip? Don’t overwater—she likes her roots dry between soaks. This one’s a keeper.
