How to Grow G13 Haze Seeds for Maximum Yield and Flavor

Get the most from your G13 Haze plants with this expert grow guide.

Quick overview: Feminized photoperiod strain from Barneys Farm. 65–70 day flowering. Medium difficulty. Ideal for indoor SOG/SCROG or outdoor Mediterranean climates.

Safe start: Germinate in a moist, dark environment at 21–32 °C (70–90 °F). Transplant gently when the taproot is 5–10 mm long.

• Use a light, well-aerated seedling mix.
• Keep humidity high (60–70%) in the first week.
• Provide gentle light (e.g., T5 fluorescents) from the start.
• For a faster start, Root Stimulator de B.A.C boosts root development.

Directed growth: Maintain a vegetative stage of 4–6 weeks with an 18/6 light cycle. This strain grows vigorously and benefits from training.

• Use LST or SCROG to control its medium stretch and maximize light exposure.
• Transplant to its final pot (11–20 L) during late veg.
• Keep pH at 6.0–6.5 (soil) or 5.8–6.2 (coco).
• For strong, green growth, Canna Start provides a balanced nutrient base.

Efficient flowering: Switch to a 12/12 light cycle to initiate flowering. G13 Haze develops dense, resinous buds over 9–10 weeks.

• Reduce humidity to 40–50% to prevent mold.
• Support heavy colas with stakes or a trellis.
• Feed with a bloom-focused fertilizer rich in phosphorus and potassium.
• For maximum resin and flavor at the end, Sensi Bloom A+B Advanced Nutrients optimizes bud development.

Harvest and refinement: Harvest when trichomes are mostly milky with some amber for a balanced high.

• Flush your plants with plain water for 7–10 days before harvest.
• Dry slowly at 18–22 °C (64–72 °F) and 50–60% RH.
• Cure buds in jars for 2–4 weeks, burping daily.
• Proper curing enhances the smooth citrus-pine flavor.

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you, G13 Haze is one of those classics that reminds you why you fell in love with sativas in the first place. I grew it last season in my SCROG setup, and the way it filled the screen with dense, sticky colas was pure art. The high is incredible—immediate cerebral euphoria that doesn’t send you into the stratosphere. It’s the perfect strain for a long workday; I stayed focused, creative, and totally present. The flavor is top-tier: a sharp citrus punch that mellows into a smooth, earthy sweetness. It’s not the easiest plant I’ve grown—watch your humidity—but the reward is a premium, flavorful bud that’s consistent every time. If you want a high-THC sativa that delivers on every level, this is it.
