Xpie77 Grow report: Seeds Genetics Gorilla Glue - Week 4 of the Growth Phase (update)
Date: March 5, 2026
Strain: Gorilla Glue (Seeds Genetics)
Number of plants: 5 pieces
Current status: Average height now 17 cm (they are still growing quite slowly/compact in this phase, possibly due to genetics, LED intensity, or slight stress earlier).
Setup:
Pots: 11 liters with standard potting soil.
Lighting: 450W Bestva LED on an 18/6 cycle.
Tent: Mammoth Elite.
Ventilation: 2x 15W fans.
Humidity: 50-60%, temperature 24-28°C day / 18-22°C night.
Water/nutrients: Every 3-4 days, half-strength grow nutrients, pH 6.0-6.5.
General Observations
The plants are now about 17 cm tall and show compact, healthy vegetative growth. They have 5-7 nodes per plant, with strong side branches starting to develop. Leaves are dark green, thick, and shiny – no nutrient issues or discoloration visible. Gorilla Glue often grows a bit bushier and slower in the early veg phase before the real stretch comes, so this is normal.
The 450W LED provides good coverage, but at this height, the distance is likely still 40-50 cm to prevent leaf burn. Air circulation is fine, no mold or pests. All 5 plants are growing quite uniformly, with slight variation in leaf structure.
Below are a few examples of what Gorilla Glue plants can look like around this size/veg phase:
Detailed Plant Status
Plant 1: 17 cm, 6 nodes, sturdy stem, starting side branches.
Plant 2: 16-17 cm, compact, healthy leaves.
Plant 3: 18 cm, slightly faster, ready for light training.
Plant 4: 17 cm, uniform, good leaf spread.
Plant 5: 16 cm, robust, slight earthy smell noticeable.
Potential Adjustments
Continue light training (LST or topping) if you want more width.
Consider increasing nutrients slightly if they start growing harder.
Monitor stretch in the coming week; they can get longer quickly.
Next update: hopefully around 25-35 cm if the veg continues.
So far, everything is on schedule – compact but strong!

Xpie77 Date: March 12, 2026
Strain: Gorilla Glue (Seeds Genetics)
Number of plants: 5 pieces
Current status: Average height now about 28-32 cm (they're picking up speed in this phase, with clear expansion of side branches and nodes).
Setup:
Pots: 11 liters with standard potting soil.
Lighting: 450W Bestva LED on an 18/6 cycle (distance adjusted to ~35-40 cm for better penetration without stress).
Tent: Mammoth Elite.
Ventilation: 2x 15W fans (air circulation strong, temperature stable at 25-28°C day / 19-22°C night).
Humidity: 50-55%.
Water/nutrients: Every 3 days, now full strength grow nutrients (high NPK in nitrogen), pH 6.2-6.5. Run-off checked, no buildup.
General Observations
Week 5 brings a clear acceleration in vegetative growth. From the compact 17 cm in week 4, the plants have now stretched significantly and become bushier. They have 8-10 nodes per plant, with strong side branches developing well – typical for Gorilla Glue, which often starts slow but then suddenly pushes. Leaves remain dark green, thick, and healthy, with a slight shine. The smell is getting stronger: a mix of earth, pine, and light citrus is starting to emerge, but not overwhelming yet.
The LED is doing well at this height; no burning, but nice node spacing. All plants are growing uniformly, with minimal differences. I've applied LST to 3 plants to flatten the canopy and get more light down. No pests, no deficiencies – the potting soil is still holding up great.
Here are a few examples of what Gorilla Glue plants can look like around week 5 veg (bushy, healthy veg growth):
Detailed Plant Status
Plant 1: 30 cm, 9 nodes, strong side branches after LST. Central top still dominates, but width is growing quickly.
Plant 2: 28 cm, compact but bushy, perfect leaf structure.
Plant 3: 32 cm, the longest grower, multiple tops after light training.
Plant 4: 29 cm, uniform, good spread, light defoliation for airflow.
Plant 5: 31 cm, robust with a thicker stem, smell strongest here.
Potential Adjustments
Keep training (more LST or topping on 1-2 plants) to maintain a balanced canopy for the switch to flowering.
Slightly increase nutrients if they're growing harder, but watch for tip burn.
Monitor for stretch; Gorilla Glue can stretch significantly in the last veg weeks.
In about 1 week likely switch to 12/12 if height is ~40-50 cm (depending on desired final size).
Everything is running smoothly – the plants are building up nicely for a strong flowering phase! Expecting more stretch next week.

Xpie77 Grow Report: Seeds Genetics Gorilla Glue - Week 4 of the Veg Phase → Week 1 of the Flowering Phase
Date: March 19, 2026 (switch to flowering around March 15-17, now week 1 flowering)
Strain: Gorilla Glue (Seeds Genetics, photoperiod)
Number of plants: 5 pieces
Current status: Average height now 45-55 cm (significant stretch during the transition, from ~30 cm at the end of veg to here – typical for GG, which often stretches 50-100% in the first weeks of flowering).
Setup:
Pots: 11 liters with standard potting soil.
Lighting: 450W Bestva LED, now switched to 12/12 cycle (from 18/6). Distance ~30-35 cm to manage stretch without burn.
Tent: Mammoth Elite.
Ventilation: 2x 15W fans (good airflow is crucial now that the plants are getting closer together). Temperature 24-27°C day / 18-21°C night.
Humidity: Reduced to 45-50% to prevent mold during flowering.
Water/Nutrients: Every 3 days, switch to bloom nutrients (higher P/K, lower N), pH 6.0-6.4. Run-off checked.
General Observations
After the switch from 18/6 to 12/12 in the last days of week 5 veg (around 40-50 cm height), the stretch has kicked in hard – Gorilla Glue is known as a stretchy hybrid, and we can clearly see that here. The plants have grown significantly taller and wider in just a week, with new node spacing and pre-flowers developing quickly. White pistils (thin hairs) are appearing en masse on the nodes and tops – the first real sign of flowering. Leaves remain healthy dark green, but some fan leaves are starting to lighten a bit (normal during transition).
The smell is getting stronger: that classic Gorilla Glue mix of earth, diesel/pine, and light sweetness is really coming through now. No pests, no deficiencies, but some extra defoliation and LST adjustments have been made to better distribute light and maintain airflow. The tent is filling up nicely with 5 plants; managing the stretch was key to avoid growing into the light.
Here are a few examples of how Gorilla Glue plants look in week 1 of flowering (early pistils, stretch, beginning bud sites):
Detailed Plant Status
Plant 1: ~52 cm, strong stretch (+~20 cm), pistils everywhere on nodes and top. LST keeps it flat.
Plant 2: ~48 cm, remained compact but now stretching, white hairs prominent.
Plant 3: ~55 cm, the stretch champion, multiple pre-bud sites, smell the strongest.
Plant 4: ~50 cm, uniform, good pistil development, light defoliation for air.
Plant 5: ~49 cm, robust, thicker stems, pistils starting to curl.
Potential Adjustments
Stretch seems to be peaking now; expect some more elongation in week 2 of flowering, but then it will focus on bud swelling.
Nutrients: Continue using bloom formula, possibly add PK boost as bud sites fill.
Keep humidity low (40-50%) and airflow high to prevent bud rot – GG can make dense colas.
Monitor for nutrient burn; LED + stretch can make them hungry.
Next week: Week 2 flowering – buds will really start to form.
The switch has been successful and the plants are responding strongly – promising for thick, resin-rich colas later! Stretch was significant, but under control.
Xpie77 Grow report: Seeds Genetics Gorilla Glue - Week 5 of the Flowering Stage
Date: April 16, 2026
Type: Gorilla Glue (Seeds Genetics)
Number of plants: 5 pieces
Current status: Average height 68-78 cm (stretch completely stopped, now fully focused on bud swelling and trichome production).
Setup:
Pots: 11 liters with standard potting soil.
Lighting: 450W Bestva LED on a 12/12 cycle (distance ~25 cm for maximum light intensity).
Tent: Mammoth Elite.
Ventilation: 2x 15W fans (good air circulation, temperature 23-26°C day / 17-20°C night).
Humidity: 38-45% (kept low due to the increasingly dense buds).
Water/Nutrients: Every 3 days, flowering nutrients with PK boost, pH 6.0-6.3. Run-off checked to prevent.
General Observations
Week 5 of flowering is an excellent phase for Gorilla Glue. The buds are clearly swelling and becoming denser and fuller. The colas are now nicely tight, covered with a thick layer of white pistils and a sparkling layer of trichomes already visible. Some pistils are starting to color slightly to orange/brown – a good sign that flowering is progressing.
The smell is quite strong by now: the typical Gorilla Glue mix of diesel, earth, pine, and a sweet undertone fills the tent. Leaves remain largely healthy dark green, with some natural yellowing of the lower fan leaves (which I have removed). Additional defoliation is done to get light and air to the buds. All 5 plants are growing very uniformly and show no signs of pest deficiencies.
Here are a few examples of how Gorilla Glue plants look around week 5 of flowering (thick swelling buds, developing trichomes and pistils):
Detailed plant status
Plant 1: 75 cm, central cola well-filled and compact, trichomes clearly visible.
Plant 2: 70 cm, bushy with multiple thick side tops, pistils still largely white.
Plant 3: 78 cm, the largest and most productive, strong smell and beginning resin shine.
Plant 4: 68 cm, very balanced, buds swelling quickly and uniformly.
Plant 5: 72 cm, robust tops, light orange pistils on older parts, good trichome development.
Powerful Adjustments
Continue using PK boost to maximize bud swelling in weeks 6-7.
Keep that low and airflow high – the buds are getting denser, so mold prevention is important.
Check trichomes regularly with a loupe (goal: 50-70% cloudy + some amber for harvest, usually around weeks 8-9 for this strain).
Some light defoliation possible in week 6 if the canopy gets too dense.
Next week: Week 6 flowering – buds will not get fuller and more resinous.
The plants are doing great! Thick, sticky colas made with the classic Gorilla Glue quality and smell. This is going to be a nice harvest.
