Final yield: 116 grams
THC content: 23.04%
Tsarina Feminized is a 60% indica bred for the 2026 Sensi Seeds Breeding Grounds project in partnership with Aficionado French Connection’s Leo Stone and Professor Q. This strain was created from Aficionado’s finest lines from California (Maple Leaf Indica, Faberger, and Pianono) which were further refined at their outdoor breeding facility in Colombia, before being shipped to Sensi Seeds’ breeders in the Netherlands.
To give our Tsarina Feminized cannabis plant the best chances, we grew it beneath a 1000 W lamp in an 8-litre pot filled with BAC Lava mix. We kept our grow room at a stable 23°C during the daytime, with temperatures dropping slightly to 21°C at night and a relative humidity of 65% during the vegetation stage.
Germination & seedling
To germinate our seed, we used the Paper Towel Method and simply folded up a few paper towels, placed them on a plate, and sprinkled them with just enough water so they were damp, but not dripping wet. Next, we placed our seed on top and covered them with another damp paper towel before placing it all inside an open plastic bag and leaving it in a warm place out of direct sunlight.
After a couple of days, our seed had cracked open, and the taproot was now sticking out about a centimetre. We then planted our seed, with the taproot pointing down, into a pre-soaked Rockwool cube and put that underneath a 600 W lamp so as not to overload it at this fragile stage.
At this point, seedlings are incredibly delicate and too much light, heat, water, or even nutrients can prevent them from sprouting. After three days, we gave our plant its first feeding with 100 ml of pH-balanced water (pH 6.2; EC 0.8) mixed with a small dose of rooting hormone.
By the end of week one, our seedling was standing 11 cm tall with a fairly slim stem, which required some extra support. By now, we were watering daily with 100 ml of water mixed with Bio Grow liquid nutrients (pH 6.0; EC 1.4).
Vegetation
At the start of week two, we moved our Tsarina Feminized cannabis plant to an 8-litre plastic pot, set it under our 1000 W lamp, and doubled the volume of water to 200 ml per day. Throughout the week, our plant doubled in height to 22 cm and sprouted a few new sets of leaves along moderate internodal spacing.
In week three, our plant continued its rapid growth to reach a height of 31 cm and grew multiple new sets of leaves while the first lateral branches began to appear. By now, the stem was thick enough to support the plant without assistance. With all of this rapid growth, we once again doubled our daily feedings to 400 ml.
Before switching to flowering, we hung satchels of Neoseiulus californicus and Amblyseius swirskii from the plant’s lowest branches. These small packets are filled with hundreds of tiny bugs that have a symbiotic relationship with cannabis plants, so they don’t harm the plant at all but hunt down and eat pests like spider mites and thrips, which can destroy even the healthiest plant. These satchels are replaced every four weeks to ensure a fresh supply.

Flowering
As we entered week four, we made the switch to flowering by flipping our lights to a 12/12 day/night cycle and changing our watering habits. We were now feeding our plant with 800 ml of water (pH 6.0; EC 1.8) mixed with Bio Flower liquid nutrient. By the end of the week, our Tsarina Feminized plant was 37 cm tall with multiple new sets of leaves growing from fairly long internodal spaces, while the lower lateral branches were starting to take shape.
In week five, our plant grew to a new height of 44 cm, and new branches were beginning to grow from the upper inner nodes. By now, the plant had developed a slight lean, though it was still perfectly capable of standing on its own. This wouldn’t ever truly go away, but the plant would mostly correct itself as the weeks went on. We were now watering with 1000 ml per day to keep up with the new growth.
Week six saw our plant gain 10 cm to finish the week standing 54 cm tall. The lateral branches were developing rapidly, and the plant was taking on a much bushier appearance, though internodal spacing remained on the longer end. While the curve in the lower stem remained, the plant had largely straightened out and was growing completely vertically. With flowering set to kick off soon, we upped the daily water to 1500 ml; this wouldn’t change for the rest of the grow.
Over week seven, the plant continued its steady growth, climbing 9 cm to a new height of 63 cm. The lateral branches were growing rapidly, and the plant had taken on a rather cylindrical shape, with the branches staying fairly close to the main stem.
In week eight, our plant’s vertical growth slowed down a bit, reaching 68 cm tall. This slight slowdown was accompanied by explosive growth of the lateral branches, which were stretching outwards and upwards to give the plant a classic Christmas tree shape. By now, we were seeing the very first pistils appear at the tops of branches, showing that flowering had officially begun.
Week nine saw our plant grow to a height of 75 cm as the lateral branches continued to grow, developing a fairly even canopy and giving the plant a very lean, airy frame. Each flowering site was now displaying a small cluster of pre-flowering pistils, and full bloom was setting in.
Throughout week ten, our Tsarina Feminied plant began to slow down its vertical growth, gaining only 5 cm to finish at a height of 80 cm. The lateral branches mostly stopped growing longer as well, meaning that the main stem was now rising well above the lower canopy while the entire plant blossomed as flowers began to properly develop.
Week eleven was more of the same, as our plant grew another 5 cm to finish the week standing 85 cm tall. Flower development was somewhat slow, as the buds didn’t grow much larger over the week, though they did become noticeably denser.
Week twelve saw our plant slow its growth even further, growing to 89 cm. This week also saw the flowers begin to grow rapidly with each passing day. The main cola was beginning to run together, and the lateral branches were starting to be pulled down by the increasing weight of their flowers.
Over weeks thirteen and fourteen, our plant reached a height of 96 cm and the conical, chunky buds continued to grow larger and denser. Some of the lowest braces were being bent past 90° and were at risk of buckling under their own weight. Extra support for these slender branches may be needed. By now, many of the pistils had turned from white to amber, and harvest was nearly at hand.
In week fifteen, we harvested our Tsarina Feminized plant at a final height of 98 cm.
Harvest
To harvest our Tsarina Feminized cannabis plant, we cut it down at the base, removed all of the fan leaves, and hung the plant upside-down to dry. Our drying room is kept at a constant temperature of 15.5°C and relative humidity of 50%, and we left our plant here until the smaller branches were dry enough to snap when bent. On average, this drying process takes 10-20 days, depending on the size of the plant.
Once dried, we removed the buds and trimmed off the remaining leaves. Trimming these flowers was fairly quick and simple, as they had somewhat light vegetation and were fairly large and dense. Once trimmed, the buds were put into glass jars for curing, and the jars were left open for 24 hours to allow lingering moisture to evaporate. After a day, the jars were sealed and “burped” several times a day, with the frequency being reduced to once per day over the next several weeks. Typically, the curing process takes 4-6 weeks and is key to creating a smooth flavour in your final product.
In the end, we were able to harvest an impressive 116 grams of dried flowers with a THC content of 23.04%.

Terpene profile
As our Tsarina Feminized cannabis plant approached maturity, it began giving off a powerful, room-filling aroma dominated by tart cherry pastries, caramelised citrus peels, notes of creamy dessert, and a subtle musky, gassy aura. This smell was truly powerful, and discreet growers should be prepared.
Once the buds were dried, they kept their powerful scent, which was highlighted by sweet cherries, citrus custard, roasted caramel, and a hint of buttery brioche alongside musky, nutty undertones. These scents all make an appearance in the flavour, which starts with a burst of sweet and sour cherries and baked custard. On the back end, we tasted notes of creamy caramel, nutmeg, and a subtle whisper of gas, which are all accented by a smooth, desert-like finish.
The effects of Tsarina Feminized were euphoric, warm, and mentally calming with a deep physical body stone, from its indica lineage. The sativa genetics could be felt as a subtle sparkle early on, but they were quickly followed by deep, serene body bliss that left us locked to the couch. This really is a “dessert high”, ideal for after dinner or an evening in.
