How one Ice Cream Haze plant delivered over 500g indoors

Ice Cream Haze grown indoors with SCROG

Key grow notes

• Vegetative Duration: ~7 weeks
• Flowering Duration: ~12 weeks
• Stretch: Strong vertical stretch for around 5 weeks after switching to 12/12
• Trichome Production: Very high
• Structure: Branches required a second support net due to flower weight
• Water Consumption: Up to 13 L every 2 days during late flowering
• Growth Pattern: Vigorous, sativa-dominant growth with excellent SCROG response
• Overall Performance: Robust plant with heavy yields and excellent resin production

Early growth: strong roots and easy training (week 1–7)

Germination took place in a small 0.2 L coco/perlite mix at 75% humidity and 22–24°C. Max used Greenhouse Feeding Bio Grow, Alpha Boost, Plagron Sugar Royal and Power Roots. The feminised seed popped normally and developed strong roots quickly.

The young plant was transplanted into a large 75 litre cloth sack filled with 70% coco and perlite, plus 30% compost, worm castings, rock flour and Bio Grow. Mycorrhiza was added for extra root support. Humidity stayed at 60–65%, temperatures 22–24°C, with pH-adjusted water (6.2–6.4) given every two days in increasing volumes.

During veg, nutrients included Plagron Power Roots, Pure Zym, Calmag, Alpha Boost, molasses and Greenhouse Feeding Enhancer every two weeks. The plant was topped once and placed under a SCROG net around one month after germination in an 80×80 cm tent under a Greenception GCX 4 LED.

She responded very well to training, with regular defoliation and tying down. Towards the end of veg, small doses of Plagron Coco A&B were introduced as a gentle boost. Watering increased to 6–8 litres every two days. By the end of the vegetative phase, Ice Cream Haze had grown robustly, filled the net nicely, and showed strong, healthy roots with no major issues; perfect for the switch to flowering.

Flowering: managing the stretch and stacking buds (12 weeks)

After about one week of transition, the plant moved to a 100×100 cm tent with the more powerful Greenception GCX 9 LED. Switching to a 12/12 cannabis light cycle triggered the classic strong sativa stretch. The canopy quickly filled the first net and space to the lamp became tight.

Max added a second net to manage the height and support the increasingly heavy buds. Without it, the branches would have bowed down under their own considerable weight in late bloom. The upward drive continued for about 5 weeks into flowering but remained manageable with the double-net setup.

Humidity was kept at 45–55% with temperatures of 24–27°C. Nutrients shifted to Greenhouse Feeding Bio Bloom, with mild doses of Plagron Coco A&B from week 4, plus Green Sensation, Alpha Boost, and molasses. The plant showed a real thirst towards the end. Max poured around 13 litres every two days during flowering.

Trichome production was outstanding, with the buds looking dense and heavily frosted. The sativa side was clearly visibly in the robust structure. Overall, the plant was easy to manage despite the vigorous stretch, with no major problems beyond the expected Haze behaviour.

Harvest results: over 500g from a single plant

After 12 weeks of flowering (total ~19 weeks from cannabis seed), Max harvested. After one week of drying, the total weight was 591.33 g.

Subtracting stems, he estimates a dry yield of around 530 g from a single plant in the 75 L fabric sack under LED — a highly impressive result. The buds showed excellent bag appeal with heavy trichome coverage. Max enjoyed the entire grow:

I enjoyed working with the plant. She has shown a clear urge to stretch but otherwise actually showed no special problems.

Grower’s final thoughts

Ice Cream Haze developed very well with strong vigour and that signature sativa stretch. The robust structure made training worthwhile, and the heavy trichome production was a real highlight. While the spicy-hazy aroma with creamy sweet notes scored moderately, the visual appeal, yield and effects were very satisfying.

This grow shows why Ice Cream Haze feminised seeds remain so popular for indoor cultivation. She rewards growers who manage the stretch with excellent frost, potency, and big yields. THC levels typically average 20–22%, with some phenotypes reaching 25%+ in optimal conditions — delivering the powerful, uplifting euphoric Haze effects that connoisseurs love.
