Auto Sublimator Seeds – R-Kiem Seeds Sativa Autoflower · 20% THC & High Yields

Auto Sublimator by R-Kiem Seeds is a premium Sativa-dominant autoflowering strain designed to deliver massive yields, intense resin production, and a potent 20% THC level in record time.

Are you tired of waiting months for a photoperiod Sativa to finish, only to end up with airy buds and underwhelming resin production? Growing high-quality Sativas can often be a test of patience, requiring strict light schedules and constant canopy management to prevent them from outgrowing your indoor tent.

There is nothing more frustrating than investing time and nutrients into a long flowering cycle, only to realize your plants are stretching out of control or failing to produce that sticky, terpene-rich resin you crave. When you are forced to choose between a fast harvest and top-tier quality, your stash suffers, leaving you with mediocre flavor and a weak, short-lived high that barely gets you through the afternoon.

Auto Sublimator eliminates the wait and the hassle, bringing you the legendary genetics of the original Sublimator in a lightning-fast, 78-day autoflowering format. With its robust structure, this strain easily reaches up to 1.50 m (4.92 ft) while packing on dense, frosty flowers that yield up to 500 g/m² (1.64 oz/ft²). You get the uplifting mental clarity of a Sativa, the physical relaxation of an Indica, and a mouth-watering citrus aroma—all without changing your light timer.

Stages and monitoring of Auto Sublimator

Preparation and Start

Set up your environment correctly to give this vigorous autoflower the best possible beginning.

• Germinate seeds at a stable 22–25 °C with high humidity.
• Plant directly into the final pot to avoid transplant shock.
• Use an airy substrate like Monkey Coco 50L Monkey Soil.
• Apply Bactomatik Rex by Agrobacterias to accelerate root mass growth.

Vegetative Growth

Maximize structural development without stressing the plant during its short vegetative window.

• Maintain a continuous 20/4 light schedule for optimal photosynthesis.
• Keep temperatures between 22–26 °C and humidity around 50–60%.
• Avoid high-stress training like topping or FIMming.
• Use gentle Low Stress Training (LST) to expose lower branches to light.

Flowering and Harvest

Focus on bud density and preserving the delicate citrus terpene profile during bloom.

• Lower humidity to 40–50% to protect dense flowers from mold.
• Add Mega PK Liquid by Agrobeta during peak bloom for heavier yields.
• Flush the substrate thoroughly 10 days before the estimated 78-day harvest.
• Dry slowly at 20 °C to lock in the fresh lime aromas.

Short- and long-term advantages and benefits

• Lightning-fast cycle: Because it finishes in just 78 days, you can achieve multiple harvests per year, which means a constantly full stash.
• Massive resin production: Thanks to its Sublimator lineage, it produces a thick layer of trichomes, making it perfect for extractions and vaporizing.
• Impressive height and yield: Reaching up to 1.50 m (4.92 ft), it maximizes vertical space, allowing you to harvest up to 500 g/m² (1.64 oz/ft²) indoors.
• Balanced hybrid effects: With 20% THC and a 65% Sativa dominance, you enjoy uplifting mental clarity without overwhelming anxiety, ideal for daytime use.
• Low-maintenance growth: As an autoflower, it doesn't require light cycle changes, saving you time and reducing the chances of light-stress hermaphroditism.
• Refreshing terpene profile: Its strong lime and citrus notes provide a smooth, flavorful smoke that delights your palate with every puff.

Frequently Asked Questions

Does Auto Sublimator need a specific light cycle indoors?

For the best results and maximum yield, it is highly recommended to run a continuous 20/4 light schedule (20 hours of light, 4 hours of darkness) from germination to harvest. This maximizes photosynthesis without stressing the plant.

Can I top or prune this strain?

It is best to avoid high-stress training like topping or FIMming on autoflowers, as their short vegetative phase doesn't allow enough time to recover. Instead, use Low Stress Training (LST) to gently tie down branches and improve light penetration.

What size pot should I use?

To accommodate its vigorous growth and potential height of 1.50 m (4.92 ft), plant the germinated seed directly into an 18 L or larger fabric pot. This prevents root binding and transplant shock.

Personal Experience of Pevgrow’s CEO (Alan)

When the guys at R-Kiem Seeds dropped Auto Sublimator, I knew I had to run it immediately. As a huge fan of the original Sublimator vaporizer and the feminized strain dedicated to its creators, my expectations were sky-high. I popped a few seeds in 20 L fabric pots with a light, airy coco mix, and man, they took off like rockets. By week four, they were already showing serious pre-flowers and stretching aggressively.

During the grow, I kept the lights on a strict 20/4 schedule. What really blew my mind was the resin production. Even for an autoflower, the frost buildup started incredibly early, and the smell of fresh lime and sweet citrus filled the tent. Because they get pretty tall—mine hit around 1.40 m (4.59 ft)—I had to do some light LST early on to keep the canopy even. After a solid 10-day flush, I chopped them right around day 78. The high is exactly what you want for a creative afternoon: a sharp, clear-headed buzz that eventually melts into a nice, relaxed body vibe. If you love making rosin or just want a top-tier Sativa auto, this one is a must-have in your garden.
