The Tulga Parvati project aims to develop an autoflowering line from the Rasol landrace and Lowryder, with the possibility of multiple harvests a year for growers in India.

Rasol → Rasol × Rasol
From 30 plants, keep one male and three females as parents and work toward Rasol × Rasol seed.

In progress
Parent → F1
Grow Rasol × Rasol seed, select for resin, vigor and resilience, then cross selected plants with Lowryder for F1 seed.

Planned
F1 → F2
Cross selected F1 plants to make F2 seed.
2028
Planned
F2 → F3
Look for autoflowering F2 plants, select the best and cross them. About one in four F2 plants is expected to be autoflowering.

Log 01 / The starting point
From Parvati, with Love
Tulga Parvati begins with Rasol, a landrace from around the village of Rasol in India’s Parvati Valley. Fritz, a phenotype hunter who travels to collect local genetics, supplied the seeds for this project. The longer-term aim is an autoflowering line that could allow Indian growers more than one harvest in a year. The first step stays with Rasol itself: grow the starting material, select parents, and produce Rasol × Rasol seed. A cross with Lowryder comes later.
The starting material
The source description places Rasol at around 3,048 m, with cool, wet summers and snowy winters. It describes an April-to-November growing season, flowering of 10–13 weeks, outdoor height of 1.8–3 m, and aromas of tutti-frutti, mint, berry jam and saffron.

From seedlings to vegetative growth
The seedlings began life indoors under a 650 W LED with drip irrigation and continued into vegetative growth there. The plants grew in Terra Aquatica soil and grow bags, with Powder Feeding Hybrids and Terra Aquatica nutrients. The outdoor site for the next phase sits at 840 m.

In this grow, Rasol has shown a sativa-like frame: long branches, good lateral growth, an open canopy and narrow, elongated leaves.

Log 02 / Selection
One Him, Three Hers
Selection narrowed an initial group of 30 Rasol plants to one male and three females as parents for Rasol × Rasol seed.
Clones preserve all four selected plants. Some remain in the mother room; other female clones are flowering indoors, allowing comparison of the three candidates through harvest. The outdoor plants are there to adapt and produce Rasol × Rasol seed for the next selection round.
Into the outdoor bed
The selected plants moved outdoors in early April. By mid-May the bed was established, and the late-May photographs show how the plants were developing in the open air. The next Rasol × Rasol generation will supply candidates for the later Lowryder cross, with resin, vigor and resilience guiding selection.

He Made the First Move
Flowering did not progress at the same pace indoors and outside. Outdoors, male flowers appeared from late May. In June, the female plants showed individual pistils at the nodes, but they had not yet reached the indoor clones’ stage of flowering.

By mid-June, the female plants were growing on outdoors. The photographs record their structure and narrow leaves at this point, while flowering continued to develop.

Indoors: the clones flower earlier
The female clones indoors were ahead of the outdoor females. Inflorescences were already visible in early June, and the plants were flowering by mid-June. The clones preserve the parent material while showing how each selected female develops through harvest.
At the beginning of September, the outdoor male plants carried many flowers, some already open. By late September, the female tops had their first inflorescences with pistils. The outdoor parents have finally reached the flowering overlap needed for the Rasol × Rasol cross.

Seeds to come
The male and female plants are now flowering at the same time outdoors, with Rasol × Rasol seed the next milestone. The next planned step is an indoor grow of those seeds. Selection will focus on resin, vigor and resilience, followed by a cross between the best candidates and Lowryder to produce the first Rasol × Lowryder F1 seed.
