Preparation and Start

Begin with a solid foundation to avoid stressing this fast-growing autoflower.

• Germinate seeds at a stable 22–25 °C (71.6–77 °F).
• Plant directly into the final 18 L pot.
• Avoid transplanting to prevent stunting the taproot.
• Use Bio Rhizotonic by Biocanna for explosive early root growth.

Vegetative Growth

Maximize structural development before the plant automatically switches to flowering.

• Maintain a constant 18/6 or 20/4 light cycle.
• Keep the substrate airy and water only when dry.
• Avoid high-stress training; stick to gentle leaf tucking.
• Apply Automatik Fuel Cannotecnia for perfectly balanced autoflower nutrition.

Flowering Stage

Focus on environmental control and bud density as flowers begin to stack.

• Lower relative humidity to 40–50% to prevent bud rot.
• Ensure good airflow around the dense central cola.
• Add Carbobloom Cannotecnia to boost resin and sweet flavors.
• Keep temperatures around 20–25 °C (68–77 °F).

Harvest and Curing

Patience at the end guarantees the best flavor and a smooth smoke.

• Flush the substrate thoroughly 10 days before chopping.
• Harvest when trichomes are mostly milky for deep relaxation.
• Dry slowly at 18–22 °C (64.4–71.6 °F) in the dark.
• Cure in glass jars for 3 weeks to maximize sweetness.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve always had a soft spot for the original Bubblegum, so when TH Seeds released this auto version, I had to run it in my personal tent. What surprised me the most was how incredibly stable and fast it is. I didn't have to overcomplicate the feeding schedule; it just grew vigorously and started stacking frosty buds right on time.

For my setup, I kept it in an 18 L pot under a 20/4 light cycle, and the sweet, candy-like aroma took over the room by week six. It’s a must-have in my kit for those times when I want a quick, reliable stash of nighttime smoke. The body stone is heavy and deeply soothing, perfect for chilling out after a long day at the office.
