Kerosene Krash 275g indoor harvest from two plants

Kerosene Krash indoor harvest insights

@marianomariano started with a 3-pack of Kerosene Krash feminised seeds, but 1 seed didn’t germinate. This left two seedlings which were grown indoors using LED grow lights. The grow room measured Home Box 120cmx90cm×180cm and two LED grow lights, each with 180W (total = 360W).

Each Kerosene Krash plant was germinated in a 1 litre container and then, about a week later, placed in an 18-litre container filled with a light mix soil which was enriched with mycorrhizae fungi. Nutrients came from Top Crop.

After 3 weeks of growth, the cannabis plants were tied down using low stress training (LST). The first nutrition was offered when the plants were around a month old. After that, the Kerosene Krash plants were allowed a long 10-week period of vegetative growth and then a 9-10 week bloom period.

Kerosene Krash is an elite indica strain made with some of the most consistently powerful, and pungent, USA cannabis genetics ever found by Dutch Passion. As the frosty bud pictures show, the combination of LST, long veg time and expert plant care resulted in a dream XL harvest. The buds and sugar leaves enjoy an unusually dense, oily trichome coating. The type of pro-grade buds you just can’t wait to vape/smoke!

Kerosene Krash grow diary by Mariano Mariano

As a relatively non-stretchy indica dominant cannabis strain, many repeat Kerosene Krash growers tend to offer a slightly longer period of veg growth especially when chasing the heaviest harvests. In this grow, @marianomariano allowed a generous 10-week period of veg growth. This allowed the Kerosene Krash plants to build a large frame with numerous branches and potential bloom points. Here are some comments made during veg growth:

In the following weeks, I continue to bend branches and I carry out a daily light defoliation – the growth is explosive all the time. Phenotype #1 grows faster than phenotype #2 and is now presenting thinner leaves from its more sativa-leaning genetics.

In the sixth week, I decide to top phenotype #2 and create more growth points. The stress of topping doesn’t seem to create any problems, nor does it slow down growth. In a short time, I find myself with a plant with 32 healthy and strong (apex) growth points. I let the plants grow in height by continuing to bend the branches for the next four weeks.

In the first stage of the grow, @marianomariano focussed on creating a large, multi-topped grow with numerous side branches. The choice of large (18 litre) containers, long 10-week veg period and powerful LEDs is the right selection for the heaviest yields.

These conditions are also recommended to any growers keen to maximise their indoor cannabis yields in general. As the two Kerosene Krash plants completed 10 weeks of lush veg growth, the time approached for indoor bloom to begin.

In the tenth week, I decide to start bloom and initiate (on both plants) a more aggressive defoliation leaving the stems bare for the first 20 cm. The stretch lasts about two weeks for both phenotypes. The distance between the internodes is good, the leaves/flower ratio is excellent. Unlike phenotype #1, phenotype #2 remains more compact.

Kerosene Krash resin production in overdrive

The indica-dominant Kerosene Krash genetics tend to show relatively modest stretch, often just stretching for 2 weeks at the start of the cannabis flowering phase. The onset of bloom also accelerated trademark terpene production.

The scent starts in a subtle way, but by the end of bloom the citrus chemical-fuel pungency is impossible to hide. Just a brief opening of your tent is enough to fill the air with reeking diesel aromas which have a pleasantly appealing and clearly satisfying quality.

From the third week after the switch, the first pre-flowers and trichomes begin to appear. The perfumes are now being felt.

Day after day the size of the flowers increases and with them the smells. Phenotype #1 seems to be ahead of phenotype #2. However, phenotype #2 delivers a production of trichomes never seen before, it’s a show for my nose and for my eyes. At the sixth/seventh week of flowering phenotype #1 seems almost ready to be harvested while after a thorough check I notice that phenotype #2 has pollen sacs on various internodes and between the flowers.

Rogue male flowers manually removed

Seeing a few male pollen sacs so late in the grow (around week 8+) is seldom cause for panic and can happen with any plants grown from feminised seeds, though it is unusual. Most of the buds and resin have already been produced by this stage.

Pollen is normally required at around weeks 3-4 for successful seed setting. Any pollen sacs seen around week 8 (or later) are far less likely to cause any issues. The correct approach was followed by @marianomariano who simply sprayed with water (this immobilises the pollen) and then removed any pollen sacs found during the daily checks.

At this point I spray with water and proceed to remove the pollen sacs. The growth of the flowers is affected but the production of resin continues relentlessly. In the following days I find small pollen sacs forming again and I eliminate them completely.

At the end of the eighth week of bloom, phenotype #1 is finally ready. The percentage of opaque/cloudy trichomes is around 65% with a small % of amber trichomes. Phenotype #2 still needs about two more weeks before harvesting.

At the end of the tenth week, phenotype #2 finally reaches the finish line. After ten days of drying, phenotype #1 is ready for curing and the weight of the dried flowers is 111g. The buds are very compact and fragrant, the terpene profile is very sweet and fruity and very reminiscent of a citrus mix.

After 12 days of drying, Phenotype #2 reaches a weight of 164g of dried flowers. Here too the buds are very compact and heavy with an important amount of resin. The terpene profile is very pungent and varies from diesel to fruity to spicy.

A super genetic that I will certainly grow again and that I recommend everyone to try.

Kerosene Krash expert tips for indoor growers

As the pictures show, this was an incredible harvest offering all the qualities demanded by connoisseur growers. An incredibly thick, velvet-like coating of trichomes, some gorgeous autumnal hues to the buds and one of the most penetrating chem-fuel scents you will ever find on an indica strain of this calibre. Well done to @marianomariano on a fantastic grow and some eye-catching, envy-inducing photographs!

This was a well-executed Kerosene Krash indoor grow and a good example that future growers can refer to in order to maximise both quality and yield:

• Long periods of veg growth, especially when growing less stretchy indica cannabis seeds, is a good foundation for any grower aiming for true XL harvests.
• Use of larger (18 litre++) grow containers is always recommended to growers seeking the largest growth potential. Aerated grow containers, such as large felt sacks or airpots, are also highly recommended to maximise cannabis root health.
• Topping cannabis plants (removal of the growing tip of a cannabis plant) replaces a single growth apex with several more. This costs time as the plant heals and repairs, but topping is a recommended high stress training technique that can reward the fearless grower with extra yield potential.
• Use of LED grow lights is another proven way to improve quality (THC levels & total cannabinoid content) over crops grown with older HPS light technology.
• Although not used on this grow, supplemental UVA/UVB lights is another way to nudge overall cannabinoid content a few percentage points higher.

Congratulations to @marianomariano on a memorable grow with some of Dutch Passion’s most powerful cannabis seeds. Kerosene Krash is a proud member of the High THC cannabis seed collection. This invitation-only club is home only to the very strongest strains in the collection, where THC levels are proven to reach and exceed 25%.

To achieve a 275g harvest from just 2 of these fine quality plants, with supreme potency and mouth-watering flavours would make most home growers proud! These premium quality feminised seeds are also available in packs of 5 or 10 for those with the space to accommodate them!
