The cross produces a vigorous, uniform F1 generation that is highly resinous and beautifully fragrant. The flowers are very potent and produce a strong effect with an unusually clear head.
The fragrance is a blend of both lines, the sweet, syrupy ‘candy’ notes of the Kush combining with the more tart and piney fragrance of the Colombian. Based on fragrance alone the cross is unique and enjoyable. Add to that the wonderfully potent character and you’ve got a winner.
As I wrote earlier I will package exactly 100 tins of this seed, 14 seeds per tin, and offer them for sale. I will donate 100% of the proceeds to the Cannabis Genomic Research Initiative to support their research goals.
The work being undertaken by this group of researchers is groundbreaking in our industry. The knowledge and the know-how that will result from this project will spawn a wave of innovation in the Cannabis industry unlike anything we’ve ever witnessed.
If you’ve taken the time to read this far and you believe in advancing the public understanding of this crop please take a second and share this article or recommend it to a friend.
Remember, 100% your purchase of the Halcyon will go to support the CGRI. Can I count on your support? I hope so.
Transplanting cannabis seedlings from nursery trays up to bigger pots can be a messy and sometimes damaging process. This is not the case when transplanting plugs grown in tree seedling pots.
Press the empty seedling pot into the media to form a perfect hole and simply drop the seedling in. Seat the plug gently by smoothing the media with your hands. Then water in to allow the roots to settle into contact with the media. It doesn’t get any easier.
Gardening is, without a doubt, one of the simplest and greatest pleasures in my life. Most of the time, that is. I have seen my share of failures and made more than my share of mistakes.
Each time we start a new garden we begin with a picture in our mind of a successful outcome. For cannabis gardeners that picture is usually of a bountiful harvest of beautiful, fragrant and potent flowers that will supply ourselves and those we share with. As anyone who has taken up growing their own will tell you, it doesn’t always work out that way.
While marijuana is often referred to as a weed and it certainly can grow like one, it is not an easy crop to grow well. There are a number of common failures to growing the herb that can seriously compromise your results. Some of these failures are quite final and will simply kill your plants and force you to begin again.
My goal in writing this article is to draw your attention to the most common sources of failure and to help you steer clear of these potential problems. If you following these 5 Simple Rules in your first attempt, your chances of harvesting a quality crop are greatly improved.
Let’s get started. Here they are:
- Plan the timing of your garden.
Cannabis grown from seed indoors is, on average, a 120 day crop. A typical growth schedule might be 4 weeks from seed to first transplant, 4 weeks vegetative growth, then add 9 weeks to bloom and finish. That is 17 weeks, or just over 4 months.
There are people that will argue that they can finish a plant in less time and I have seen it done. But time is what it takes to make high quality flowers, so don’t rush yourself or your plants.
Also be aware of the months you’ve allocated to your garden and compare that to your personal calendar. Nothing is worse than getting 3 months into a grow and then remembering that you are supposed to travel for vacation just as your plants are beginning to bloom. Indoor gardens that are abandoned for weeks at a time frequently fail.
- Start with clean, well draining growing media.
The science of horticulture is constantly improving as are the materials used to grow crops indoors. In the past the commercial greenhouse and nursery industry used to grow their crops in clay pots and field soils.
The practice of using soils indoors has been replaced almost entirely by the use of sterile packaged growing media. The primary reason for this is to reduce the numbers of pests and pathogens that are introduced to the greenhouse.
Simply put, soil carries bugs and their larvae along with a whole raft of molds and spores. These pests, once introduced, are tough to fight and can be disastrous for your indoor garden. If the word ‘soil’ is on the label, don’t bring it indoors.
Packaged media comes in many forms. My personal preference is for Peat-Lite mixes which are comprised largely of peat moss amended with perlite, vermiculite or both.
A good usable peat-lite mix for cannabis would contain in the neighborhood of 60-65% peat. This makes for a medium weight mix that has good moisture holding capability, yet drains well.
- Use a complete fertilizer that is appropriate for your water type
Most packaged fertilizers carry on the label a guaranteed analysis of the elements inside. The most important of these are the N-P-K levels. N-P-K stands for nitrogen, phosphorus and potassium, the three macro elements that plants need to grow.
In addition to these macro elements are a group of lower concentration elements referred to as micro elements. These include calcium and magnesium, and in smaller amounts iron, copper, boron, manganese, molybdenum and zinc.
A complete fertilizer will contain all of these elements in ratios that are appropriate for growing plants. There are formulations made for growing fruits and vegetables that closely match the requirements of marijuana. These are absolutely fine for your garden.
In many parts of Colorado, home gardeners are using city or municipal water sources. Municipal water is treated to lower the calcium and magnesium content and to remove trace elements like iron.
This treatment makes the water taste better and makes it more useful for things like bathing and laundering clothes. Unfortunately for gardeners this means that there is less of these essential elements to feed the plants.
If you are on municipal water that is low in calcium and magnesium you will need to supply these to your plants via your fertilizer choices.
- Provide adequate light
The single greatest limiting factor in indoor cannabis growing is light. The most common types of artificial light used indoors to grow this crop are fluorescent and high-pressure sodium / metal halide bulbs. Both work well and can be used at all stages of growth. Both have their merits and their drawbacks. On/off time is controlled with a simple timer.
The most commonly used type of fluorescent lighting used in indoor gardens are high-output T5 bulbs. These usually come in 4 ft lengths, although 2 ft bulbs are available. The fixtures are made up of multiple tubes. Common configurations are 4-tube and 8-tube panels that can be easily hung over the plants.
T5 fluorescent lighting is highly diffused which makes it easy on the eyes. The bulbs run very cool making them the go-to choice when managing high temperatures indoors is a concern. They produce a very high quality light and can be used to grow your plants from start to finish.
High-pressure sodium and metal halide bulbs have a much higher output from a much smaller fixture. HPS/halide lights burn hot and produce huge amounts of heat energy. This all adds up to make them a more productive lighting source for indoor gardeners. Having said that, the heat energy, while easy to manage in the winter months, can be an expensive factor to try and control in the summer months.
All things being equal, my preference is to run HPS during the cold months and fluorescent bulbs in the summer. Taller plants will benefit from the extra punch of the HPS/halide bulbs in that the light will reach and be more effective in the lower half of the plant. Fluorescent bulbs have less power and therefore will tend to under light the lower branches of taller plants.
- Control your environment
Controlling your environment means keeping your grow area clean and clear of pests. This means removing any dead or diseased leaves from the plants, from the media and from the surrounding floors.
You must also control your ambient temperatures. Marijuana plants do very well in the 60 – 75 F range. Run your garden colder and you run the risk of slow growth and mildew/mold outbreaks. Maintaining temps higher than 80 and you invite pests like mites into your garden.
Colorado’s humidity can swing wildly from season to season. Generally you want to keep your indoor garden air moist, but not too moist. A reasonable working range is between 40 and 60% relative humidity.
It would be impossible to cover every potential problem in a single article. By paying attention to these 5 factors you will have eliminated much of the risk of failure facing first time indoor marijuana gardeners.
I have spent a good deal of time learning how to grow this plant successfully indoors. I hope you find this information useful. If so, drop me a note and introduce yourself or stop by my shop in Lafayette. One can never have too many gardener friends.

Part I of a 3-part series on managing pH in container grown cannabis
By Ben Holmes, founder of Centennial Seeds in Lafayette, Colorado.
I’ve been growing cannabis indoors continuously for seven years. Over the course of those years I have learned a few things about growing this crop. Without a doubt the most important lesson I’ve learned is the role that pH plays in healthy, productive plant growth.
Most cannabis gardeners think of pH as something that must be maintained in their water and the fertilizer solutions they apply to their crops. For the purpose of this discussion let’s think of pH as a condition that exists in the planting media, in and around the roots and in the aqueous film that coats the contents of the growing container.
In this first part we will identify three components of your grow that significantly impact your media pH: the growing media, fertilizers and water.
In my lab I grow in Fafard Peat-Lite media. I use a variety of Fafard mixes from their Super Fine Germinating mix to their Fafard Organic Formula FOF-30. I use their professional products in my seed production facility because they are the very best.
Peat-Lite lends some amount of acidity throughout the growth cycle, as do coco coir mixes. That acidity if allowed to progress unchecked will create unfavorable conditions at the root zone and will negatively affect plant growth.
The fertilizers we choose also affect pH in the container. More specifically, the form of nitrogen in our fertilizers greatly affects the direction of pH drift in planting media.
Nitrogen from organic sources are protein based. These proteins degrade to amino acids which degrade to ammonia and urea. Ammonia and urea can also be manufactured by industrial process. These nitrogen sources have an acidifying effect on media pH.
The second type of nitrogen, that which comes from nitrate sources has a net increasing effect on pH.
Used alone or when combined in specific ratios the two forms of nitrogen can be used to steer media pH one way or the other, up or down.
Your water and its mineral content also has an effect on media pH. The amount of calcium and magnesium carbonates present in your water determine how much buffering capacity your water has.
Water with high carbonates will work in concert with an acid producing fertilizer to neutralize the acid and to provide calcium and magnesium. Acidic water can be paired with a base producing fertilizer to counter act the increase in media pH.
This is useful knowledge, but how do you apply it to your own garden? The answer begins with a water test. If you are serious about growing cannabis you have to start with some key information about your water source. For our purposes you want to know the amount of calcium carbonates and total alkalinity in your water.
I will follow up in Part II with some examples of fertilizers that match particular water types.
The Waipi’o Hapa is a very special seed. It is a local heirloom variety originally imported from the beautiful Waipi’o Valley on the North shore of the big island of Hawaii, USA.
The Waipi’o Hapa is remarkably vigorous, finishes fast and produces heavy yields every time. The fragrance is of fresh lime and hibiscus flowers. The effects are undeniably Sativa, both stimulating and strong.
Waipi’o Hapa is recommended appropriate for: pain, energy, mood elevation, appetite suppression
The Roughneck is a hybrid Seed developed by Ben Holmes of Centennial Seeds. The seed is derived from Jamaican Lambsbread and the Purple Rhino IBL. The result is a powerful hybrid that expresses beautiful purple hues and a delicious, somewhat savory bouquet.
With its heavy Sativa influence, the effects are very strong and markedly stimulating. Roughneck is recommended appropriate for: pain, focus, mood elevation, appetite suppression.
The plant is easy to grow and very productive. Examples of Roughneck have tested >22% THC.
The Dakini Kush is a highly-productive, highly-resinous Indica variety developed in Colorado, USA by Ben Holmes of Centennial Seeds.
The plants produce very large, dense flowers that are literally matted with glistening trichomes. The fragrance is classic Hindu Kush with enticing notes of sandalwood, myrrh and hops. The effects are strong and relaxing.
The Dakini Kush is recommended appropriate for: chronic pain, anxiety, sleep, mood elevation, appetite stimulation.
The Dakini Kush is easy to grow and extremely productive. Examples of Dakini Kush have tested >22% THC.
