Review & Effects
Black Jack strain is worshipped by many potheads and is one of the most popular strains. Black Jack strain cannabis is a cross between Jack Herer and Black Domina. The result is an Indica-dominant hybrid. Black Jack strain was created by Sweet Seeds. Also, there is another variety of this pot bred by Nirvana Seeds. This kush is sativa-dominant, and one of its parent strains is different. This post portrays the phenotype where Indica dominates.
Requirements for Growth
How to Start Seeds of
You can start your seeds in damp paper towels, coffee filters, napkins, or seed starter plugs. Simply dampen the medium with distilled water, place the seeds on the medium, and store in a warm, dark place for 3-5 days.
Once your seeds have sprouted, be sure to transfer them into soil or some other type of substrate as soon as possible.
The Best Soil for Growing
Tupur Mix is a coco fiber-based soilless medium that contains a heavy amount of perlite; and nothing else.
In other words: It's the PERFECT growing medium for seeds, clones, and young plants.
Keep in mind that while mature plants LOVE stuff like seabird guano and earthworm castings, whereas younger plants prefer clean, well-draining soil; and a light nutrient regimen that gets progressively stronger as the plant grows.
That's why we love Tupur Mix - it allows for MAXIMUM control over your feeding regimen!
This substrate is designed to let you feed your plants as often as possible without overwatering or burning your plants.
These unique factors make Tupur Mix ideal for young plants in containers, automated watering systems, drip-to-drain, ebb-and-flow, deep water culture, and aquaponic gardens.
Tupur Mix strikes the perfect balance between drainage and moisture retention while still allowing for adequate aeration to prevent water logging.
How to Plant Clones of
When repotting a plant, the substrate should always come out of the smaller container in one piece.
Another key to transplanting clones is to make sure that the substrate in the new container is saturated with water to allow you to pack the soil down around the plant once it's been transplanted.
Best Nutrients for Growing
Stop wasting money on overpriced nutrients and start getting the results you want with this COMPLETE nutrient regimen! The Humboldt Secrets Starter Kit will allow you to grow the PERFECT crop every time!
The Humboldt Secrets starter kit has everything you need to get your plants through to harvest and enough concentrate to make between 125 - 150 gallons of solution!
This premium line of nutrients is compatible with all growing mediums and works equally well indoors, outdoors, and in greenhouses!
The Humboldt Secrets line is one of only a few cannabis-specific nutrient products and is made with premium ingredients for maximum nutrient uptake.
That's why we recommend it!
Best Light for Growing
The best indoor grow light on the market today is the Gavita Pro 1700e LED 120-277 Volt. This versitile, full-spectrum LED light delivers the perfect balance between output and efficency!
The Gavita Pro 1700e offers full lighting control and plug-and-play adaptability. Plus, this unique LED array is designed to omit the perfect wavelength of light for maximum growth and optimum plant health.
There simply is no substitute.
For additional control over your light cycle; including automatic sunrise and sunset, auto-dim/auto-shutdown, and temperature calibration; we recommend also purchasing the Gavita Master Controller EL2.
Nutrient Deficiencies in
For help diagnosing and correcting nutrient deficiencies, refer to the chart below. For more information about diagnosing nutrient deficiencies in cannabis, be sure to read: "What's Wrong With My Plant? - Diagnosing Nutrient Deficiencies in Cannabis."
When to Top Your
We recommend topping your plants when they're about 24 inches tall and before they begin flowering.
Growers who choose to employ low-stress training techniques (SCROG or SOG) may end up topping multiple times.
Topping a plant temporarily deprives it of growth horomones called auxins that are present in the tips of the shoots and regulate vertical growth. In the absence of these hormones, the plant begins to grow horizontally for a few days until the auxins recover.
This "horizontal growth" leads to the development of multiple meristems that can each eventually support a large flower.
That's why topping is a widely accepted practice that has been shown to dramatically improve yields.
Possible Side Effects of
Marijuana consumption may trigger adverse effects in some people. Less experienced consumers are more likely to experience side effects, including but not limited to:
Dry or Red Eyes
Increased Heart Rate
In general, these effects dissipate after a few minutes as your body metabolizes the THC.
