We could hardly wait to get our Papi Chulo OG Feminized germinated, but we knew it was essential to prepare our growing area. For lighting, a 1000W Green Power Phillips HPS bulb was attached three metres above the rim of our pots. BAC Lava Soil Mix was the chosen medium, and throughout the different stages of growth, we supplemented Bio Grow or Bio Bloom. The EC levels of our nutrient solution varied, but it was always pH’d to 6.0 before applying it to our plants.

To encourage growth, Papi Chulo OG Feminized received a light schedule of 18 hours on and 6 hours off throughout vegetation. The lighting schedule was then switched to 12 hours on and 12 hours off to initiate flowering. Daytime temperatures reached 23°C before dropping to 21°C during the night. As the cycle progressed, humidity levels were reduced from 65% to 60%. Oscillating fans circulate air around the canopy, and inline fans extract odorous, stagnant air through the carbon filter.

Germination & seedling

To germinate our Papi Chulo OG Feminized, we placed our seed between two moist paper towels enclosed between two ceramic plates. After 36 hours, a short taproot emerged from the paper towels, and we carefully removed our seed before placing it taproot down into its new 1-litre container. 

Always remember to put the seed taproot down, this will help establish the root zone, and the shell casing will be removed naturally as the root pushes it upwards and out of the ground. Throughout the remainder of week one, we supplemented 100 ml of water with an added root stimulant around the base of the stem.

Vegetation

In week two, our Papi Chulo OG Feminized had grown to 13 cm, and we knew the root system was developing. To encourage further growth, we implemented Bio Grow nutrients with an EC value of 1.4. The volume remained the same at 100 ml, and the solution was applied around the base of the stem. On the 10th day, we discovered feeder roots peeking from the drainage holes of our container and transplanted our seedling into a 5-litre container to encourage continued root growth. 

The introduction of Bio Grow and the extra room for the root zone fueled rapid growth, and in week three, we were excited to see that our Papi Chulo OG Feminized had doubled in height. Our plant had developed seven-finger leaves with a vibrant, lime-green colour with sharply serrated edges. Lower auxiliary branches were extending, and internodal spacing was average. By the week’s end, Papi Chulo OG Feminized reached 27 cm, and the volume of the solution was raised to 400 ml.

Throughout week four, we increased the nutrient levels and raised the final EC of our solution to 1.8. The volume of the solution was doubled to 800 ml and applied evenly over the surface. Unwilling to use chemicals, we release predator insects that hunt and pest-damaging insects. Satchets of Neoseiulus Californicus and Amblyseius Swirskii were placed upright on the soil’s surface to control potential pests like fungus gnats, thrips, and aphids. Throughout the week, growth remained vigorous.

Flowering

By week five, we had decided to initiate flowering and changed the lighting schedule to 12 hours on and 12 hours off to facilitate this hormonal shift in the plant. Bio Grow nutrients were discontinued and replaced by Bio Bloom nutrients. The solution EC remained at 1.8, but we increased the volume to 1000 ml, while humidity levels were reduced to 60%. Massive nine-fingered leaves were visible, and to support the additional weight, plant stakes were attached to the mainstem using plant ties. 

We assessed our plant’s performance during week six, and everything was going as planned. The amount of vegetation exponentially increased, blocking lower branches from direct light and adequate air movement. As airflow within the canopy is essential, helping to avoid microclimates of warm, moist air, we defoliated larger fan leaves and lateral branches. By the week’s end, our plant grew 20 cm, and we upped the amount of solution to 1500 ml. 

Over time, the salts from the synthetic nutrients can accumulate in the soil and cause pH problems, nutrient imbalances, and poor root health. As part of our standard operating procedures, we flushed our medium in week seven by pouring a high volume of pure water through the soil until there was around 10-15% run-off. The run-off water was removed, and after flushing, we continued our regular feeding schedule.

In week eight, white stigmas were visible on every branch tip and bud formation was beginning to take centre stage. Our plant stood 114 cm and had filled out into a well-shaped plant with a dominant apical cola. It had been four weeks since our last application of Neoseiulus Californicus and Amblyseius Swirskii, and we released another sachet of each predatory insect. Luckily, the canopy and the leaves’ underside were scouted regularly, and there were no signs of unwanted pests.

It was evident that our Papi Chulo OG Feminized was directing all of its energy towards bud formation and we recorded only 2 cm of vertical growth in week nine. The flowers on the plant were expanding and starting to connect, forming colas at the end of each branch. A layer of trichomes was now beginning to litter the surface of the sugar leaves surrounding each of the buds. As the bud swelled, we lowered our room humidity to 58%. 

Lower branches that weren’t receiving enough light were removed In week ten, and the growth energy was redistributed to other branches. As our Papi Chulo OG Feminized buds swelled, we dropped the humidity levels to 52% throughout the final weeks. We continued using the Bio Bloom nutrients at an EC of 1.8; the solution volume was 1500 ml for each application, and the pH remained unchanged at 6.0. 

Week eleven recorded no vertical growth; all the energy was spent producing flowers. As we entered the garden daily, we were greeted by floral scents ranging from sweet to pungent. Our carbon filter was working well, and outside of the grow, the smell was undetectable, but Inside, it was unmistakable. 

After four weeks of heavy feeding, we flushed our medium with pure water before resuming our regular feeding schedule. The colour of our leaves was still a healthy, deep green, which indicated there were enough nutrients for optimal growth. It had also been four weeks since our last application of beneficial insects, but as we didn’t see any issues and harvest was approaching, we opted against releasing more predator bugs.

By closely inspecting the trichome head, we discerned harvest was nearby in week twelve. We began to see amber trichome heads on the leaves but not on the flower. Checking the trichome heads on the flower is the best sign for estimating an approximate harvest date. Still, when they appear in numbers on the sugar leaves, it can be taken as a sign harvest is approaching and preparations should begin. 

We began week thirteen with us inspecting the trichome heads. As an indicator of plant ripeness, growers are looking for 10% transparent, 80% milky, and 10% amber trichome heads. On inspection, we could see an increasing number of amber trichome heads. That ratio was sure to increase over the next ten days, and we felt our Papi Chulo OG Feminized was within the harvest window to begin a final flush.

All nutrients were eliminated, and our Papi Chulo OG Feminized received pure water until harvest. We also performed a “pre-strip” of foliage, removing large fan leaves which hold unwanted moisture, subsequently helping to increase the necessary drying time when numerous plants are involved. 

In the fourteenth week, our Papi Chulo OG Feminized reached 120 cm. The majority of stigmas had turned brown and receded into swollen bracts. Trichome head inspection revealed the desired clear/milky/amber ratio and the effects of flushing were evident in the fading colour and yellow leaves. As the plant matured, alluring aromas added layers of complexity to the already enticing profile, and it was time for harvest!

Harvest

Our process for drying cannabis is standard in the industry. We first remove the large leaves from our Papi Chulo OG Feminized. Anything without trichomes will be of no use later. In climates with very low humidity, keeping this extra biomass can help slow the drying process, but in most instances, it is removed. The drying area is dark and climate controlled at 15.5°C with 60% humidity.

We cut our Papi Chulo OG Feminized at the base of the stem and brought it into the drying area to be hung upside-down. Multiple fans moved the air around the drying plants, but the precaution was not to blow directly on them. After a week, we checked the dryness of our buds. The outer layer was still moist, so we continued the hang-dry for at least another week.

On day 21 of the hang dry, the outside of the flowers reached our target moisture level. The exterior of the buds was dry and slightly crisp, but the core of each bud retained significant moisture. Once jarred for curing, the internal moisture will escape to the surface and rehydrate the outer layer. Before jarring our Papi Chulo OG Feminized, we trimmed off the excess sugar leaf and set it to the side to make edibles with later.

We filled our glass jars and left the lid off for the first 24 hours. The jars were then sealed and kept in a dark, cool cupboard. Every few hours, we would burp the jars. This is opening the jar and letting the released moisture escape. The burping process allows the Papi Chulo OG Feminized buds to reach an equilibrium of moisture levels from centre to surface. Lids were left off for an hour each time we burped for the first two weeks. 

Each time the jars were burped, our Papi Chulo OG Feminized aroma grew stronger. We were now getting a complex terpene profile that had many influences. The process of curing the jars lasted for six weeks. During the final four weeks, jars were burped only once per day. Our flowers had reached the proper degree of dryness and maintained a consistent texture each time our jars were opened.

After completing the curing process, we were left with 97 grams of premium cannabis flower. Samples were sent to a second-party laboratory for cannabinoid testing, and results came back with an extraordinary THC content of 27.26% 

Terpene profile

Papi Chulo OG Feminized has a terpene profile that predominantly consists of limonene, a-pinene, and myrcene as the significant contributors. This plant’s initial onset of detectable odours came within the last month of flower. As harvest approached, the scent grew more assertive. As the flower was hanging drying, the scent kept adding layers. By the time our buds finished curing, a complex meshing of aromas had enveloped the senses.

As the nose inhales, the air surrounding Papi Chulo OG Feminized, a sweet lemon scent backed by a refreshing pine scent, tingles the senses. Floral bouquets then provide a backdrop for musty, earthy odours and pungent skunk aromas to mingle with the sweeter side of the profile. The flavour profile is a mirror of the terpenes. Lemon and earthy notes coat the tongue, complimented by a dash of pine and Kush-like undertones.

The lineage of Papi Chulo OG Feminized is 70% indica/30% sativa, and that is representative of the multiple layers of effects. The immediate effects are uplifting. An initial blast of mind-boosting, euphoric feelings is an excellent representation of widespread sativa-like effects. This gives way to a heavy body stone that provides complete relaxation. The impacts of Papi Chulo OG Feminized were long-lasting and significant for the evening.

The outcome

We thoroughly enjoyed the cultivation cycle and were overwhelmed by the results, which produced 97 grams of top-shelf cannabis with an exceptionally appealing terpene profile and aesthetic. No training techniques were used, and the plant grew in its natural composition. However, some extra support was needed to handle the weight of the buds. The effects were hybrid, with qualities of both indica and sativa. Dried buds were electric green and covered in a layer of snowy trichomes. 

Our feeding schedule was simple, and Papi Chulo OG Feminized is a low-maintenance strain which could be an excellent addition to any new grower’s garden. Nevertheless, for people looking to push the limits, the whopping 27.26% THC content of our Papi Chulo OG Feminized is undoubtedly at the top of the scale, making it a popular choice amongst experienced consumers.
