Gorilla Cookies Auto Grow Diary and Strain Review

This run with Gorilla Cookies Auto from Fast Buds started as a three-plant indoor cycle. I knew the strain could be strong, but I mostly wanted to see how it would behave in my own box with coco, Simplex nutrients and a fairly hands-on routine.

The setup was a 120 x 60 x 180cm (47.2 x 23.6 x 70.9in) box with two LED lamps giving 300W in total. All three plants went into 15l (4gal) AeroPots filled with a prepared coco mix, and the light schedule was 20/4 from the start.

Starting the Run

Grow Notes

I started the seeds late at night in 50ml (1.7fl oz) of water with 3% hydrogen peroxide, then moved them into cotton pads by lunchtime. While they were waking up, I prepared the medium.

The base was 50l (13.2gal) of washed BioBizz Coco Mix. After washing, I had about 40-45l (10.6-11.9gal) of coco, plus 15l (4gal) of perlite and 5l (1.3gal) of vermiculite. I mixed 20l (5.3gal) of water at ppm 10-15 and pH 6.3 with 25ml (0.8fl oz) Simplex Coco A and 25ml (0.8fl oz) Simplex Coco B, then brought the solution to ppm 400 and pH 5.8. The substrate soaked for about 1h before going into the pots.

Week 1

All three seeds rooted without trouble and went into the 15l (4gal) AeroPots. Two seedlings came up first, both without helmet heads, and the third one followed later the same day. They stayed under plastic cups while they settled.

Once everything was alive and looking fine, I switched the box to 20/4. The first watering was very light: 0.3ml/l CalMag, 300g (10.6oz) for each plant, with the solution at ppm 270 and pH 5.7.

Week 2

The second week was mostly about letting the small plants establish themselves. I didn’t try to rush them with training or heavy feeding.

The young plants looked steady enough, so I kept the routine calm and watched how they reacted to the coco mix. At this point, the main goal was simple: keep the roots moving and avoid making a beginner-style mess before the plants had any real size.

Veg Progress and Training

Week 3

By week 3, the plants were ready for more attention. I started working with LST and opened the structure little by little instead of making one hard bend and hoping for the best.

Feeding was still being tuned by the numbers. The solution sat around pH 5.7 and ppm 550, and I kept checking the runoff because the coco was telling me more than the leaves at this stage.

Week 4

I installed a ScrOG net this week and kept shaping the plants through it. The idea was good, but the room was already starting to feel tight for three autos in this box.

Watering was around 3.5l (0.9gal) per pot with pH 5.8 and ppm 750. Runoff came out lower, around ppm 450-400, with pH near 6.8, so it looked like I was underfeeding. I also sprayed Delta 9 on the leaves at the end of this stretch.

Week 5

Week 5 was where the canopy really started getting inconvenient. There was a lot of leaf mass, and watering through the greenery became annoying. I removed the ScrOG net because the cells felt too small, and honestly, I got nervous about locking the plants in too early.

I kept defoliating in small sessions. The plants didn’t seem badly stressed by it: I’d trim in the evening, check in the morning, and they looked fine. The smell appeared around this time too, with something that reminded me of coffee. Feeding moved up from around ppm 820 toward ppm 900-950 because the runoff still suggested they were eating more than I was giving.

Early Flower

Week 6

Preflower had started by the end of the previous week, and now the plants were moving into real flowering. The room was stable, but the middle plant was clearly behind the other two.

I watered three times during the week, twice with nutrients. The feed stayed on the stronger side for this run, but I was still watching the runoff carefully instead of guessing. Leaf volume was still heavy, so defoliation remained part of the routine.

Week 7

At the end of week 7, I ran into salt buildup. I measured input and runoff every time, so the problem didn’t come as a complete surprise, but it still meant I had to slow down and clean things up.

The pots were flushed, and the plants were moved back toward a safer rhythm. One useful lesson from this week was that the feeding had to match not only the plant size, but also how much coco and root mass were sitting in those 15l (4gal) pots.

Week 8

Two of the plants were already close to harvest, while the middle one still needed more time. The space issue became very obvious here. Three plants in a 120 x 60cm (47.2 x 23.6in) footprint was too much for this run.

The first two plants came down around this stage and gave 300g (10.6oz) dry between them. That number made me happy, but it also confirmed how crowded the box had been. The last plant stayed in the room and went onto cleaner water before its own finish.

Late Flower and Finish

Week 9

The final week was all about finishing the last Gorilla Cookies Auto. I watered with ppm 45-70 and pH 6.2, expecting a lot of foxtailing because of my own mistakes along the way.

Even with that, the plant looked close enough to the end. I wasn’t chasing a perfect finish anymore. I just wanted to let it ripen cleanly and avoid creating a new problem in the last few days.

Gorilla Cookies Auto Yield and Final Thoughts

The last plant added another 210g (7.4oz) dry. Together with the first two plants, the full run finished at 510g (18oz) in 10 weeks. The weight definitely pleased me, especially after fighting the lack of space for most of the second half.

The only real headache was the box size. A 120 x 60cm (47.2 x 23.6in) space was just too small for three Gorilla Cookies Auto plants in this setup. During flower, the aroma in the house was extremely strong, and it was not something I could have ignored without proper filtration.

After drying, the smoke was very tasty. I picked up citrus, earth and a gasoline-like note. The effect was heavy enough that working afterward didn’t sound appealing at all. For me, this was more of a sit-down-and-watch-something strain, and it hit the body pretty hard.

My final impression is positive. Gorilla Cookies Auto gave a strong harvest and didn’t feel overly difficult, but it clearly needs space. Next time, I’d either run fewer plants or give them a wider room from the start.
