Typical mistakes this strain helps you avoid

How to grow Guava Runtz for best results

Quick overview: Feminized photoperiod hybrid. 8-9 week flowering. Ideal for indoor tents or sunny outdoor spots. Medium difficulty.

Safe Start: Germinate in a warm (22-25°C / 71-77°F), humid environment. For a strong root foundation from day one, consider using a root stimulator like Azos from Xtreme Gardening.

Veg Stage: Provide 18 hours of light. Use an airy, well-draining substrate. It stretches moderately during the transition to flower, so plan your canopy management accordingly.

Flowering Power: Switch to a 12/12 light cycle. Maintain humidity around 40-50% and ensure good ventilation. To support bud density and resin production in peak flower, a quality PK booster can be beneficial.

Harvest & Cure: Harvest when trichomes are mostly milky with some amber for a balanced effect. Dry slowly at 16-20°C (60-68°F) and 50-60% RH for 10-14 days, then cure for a minimum of 2 weeks for flavor development.

Frequently Asked Questions

Indoors, with proper training, it typically stays between 0.80–1.20 m (2.62–3.94 ft). Outdoors, it can reach 1.50–2.00 m (4.92–6.56 ft) or more if given space and a large pot.

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you, Guava Runtz is one of those strains that makes you remember why you love growing. I ran a couple of these in my personal tent last season, and the first thing that hits you is the smell during the last few weeks – it's like someone opened a bag of fancy cream-filled candies right next to a gas station, in the best way possible. The structure is a grower's dream: not too stretchy, but with enough vigor to fill out a SCROG net beautifully. I used a simple organic soil mix and fed lightly, and they just powered through without any drama. The buds stacked hard and were absolutely caked in resin by week 8. The high is exactly as advertised – a really clear-headed, chatty buzz that slowly melts into a super-comfortable body relaxation. It's become my go-to for late afternoon sessions. For beginners, I'd say don't overthink it; just give her a good base and watch her work. For my fellow veterans, try a light defoliation around week 3 of flower to let light into those lower sites – you'll thank me later.
