While fits of the giggles may briefly sidetrack, this cultivar is useful as it allows consumers to retain attention and clarity. Artists, writers, and coders become engrossed in their work, taking advantage by plowing through projects or daily chores. 

These feminized Critical Jack seeds have high THC levels of 15–20%. That means overconsumption can negate drive and energy. Don’t be led to gluttony by these seductive flowers. In moderation, users experience long-lasting, wide-ranging effects.

As with all top-shelf cultivars, consumers may note mild side effects. Bloodshot eyes and a dry mouth result from dehydration. Keep a stock of eye drops and healthy thirst quenchers. Novices, in particular, should practice moderation as dizziness and modest paranoia may occur. 

What does Critical Jack feminized smell like?

The sweet, stunning flavor of a crop grown with fem Critical Jack seeds strengthens as the buds go through flowering. The floral aroma partners with a lemon zestiness. When the buds are dried and cured, they become a light green with vivid orange pistils. 

Break them open to release the delectable terpene profile with pine, citrus, and skunky notes. The tangy lemony pine inhale boasts some spice, while the exhale presents hardwood and pepper tones with a smooth, skunky aftertaste. 

The unique flavor profile combines several terpenes in varying proportions. The main ones in feminized Critical Jack seeds are:

- Alpha pinene (25%): Alpha pinene is one of two terpenes found in large quantities in weed grown from fem Critical Jack seeds. Conifers, and especially pine trees, contain alpha-pinene.

- Beta pinene (12%): The second dominant terpene is a monoterpene found in plants. Forest trees give off this abundant compound as a woody green pine flavor. 

- Beta-caryophyllene (20%): The essential oil of cannabis sativa, hops, and rosemary, this terpene has potent anti-inflammatory, anti-bacterial, and antioxidant properties.

- Beta myrcene (10%): Thought to be the predominant terpene in cannabis cultivars in North America, myrcene is widely found in plants and used for flavors and scents in chemicals.

- Limonene (8%): Especially concentrated in the oil of orange rinds, limonene supplies citrus flavors. More precisely, it’s responsible for the tangs of lemon that typify Critical Jack feminized cannabis seeds.  

How to germinate Critical Jack feminized seeds

The first step of growing weed involves inducing the seed to open and sprout a taproot. Seeds remain dormant until they’re in the right environment. Mimic a warm, humid, damp environment to germinate feminized Critical Jack seeds. 

Homegrown guarantees germination if you follow the simple step-by-step guide that follows:

You’ll need:

- Two dinner plates

- Paper towels

- Critical Jack feminized seeds

- Tweezers

- Purified or bottled water

Instructions: 

- Use the bottled water to wet one of the paper towels. Wring out any excess water and lay the towel down in the middle of the plate. 

- Use the tweezers to place the Critical Jack feminized cannabis seeds on the paper towel. Make sure at least an inch of space separates them.

- Wet the second towel, squeeze out excess, and drape over the marijuana seeds. Carefully peel up the towels to ensure there isn’t any standing water on the plate.

- Invert the second plate and use it to enclose the medium.

- Put the plates in a warm, humid spot that’s dark. Germination calls for darkness, not light.

Check the seeds regularly to see if they’ve sprouted. Don’t expose them to unnecessary light, and ensure the towels don’t dry out completely. Your Critical Jack fem seeds should present a shoot within 24–120 hours (1 –5 days). If they haven’t sprouted a little white taproot after five days, your seeds aren’t viable and you can toss them out. Buy your marijuana seeds from a trusted source to limit disappointment.

Outdoors, these plants develop best in a warm, dry, Mediterranean climate, but greenhouses are also great. Critical Jack feminized seeds sprout a plant that can reach beyond 10 feet tall. Long internodal spacing is typical of sativa strains, and this one’s no different.

Depending on the local climate, growers should be ready to harvest from late September till late October. A trouble-free grow can net farmers as much as 42 ounces of high-quality cannabis per plant. 

Growers can rear Critical Jack feminized seeds indoors, too. Unless you have a barn, use some training techniques to contain these wild plants. Topping, low-stress training, and bending are great ways to limit height. Also, remember your plants could double in size through stretching early in bloom, so pre-flowering topping is a good idea.

The Screen of Green (ScrOG) growing method involves weaving your crop through a screen and then tying it down. This mesh makes the plants develop laterally, exposing greater areas to light and limiting height.

Indoor growers must ensure air circulation and light penetration by regular pruning and LST.

Jack Herer was a pioneering activist whose unwavering support for hemp and cannabis legalization made him a pop icon. The sativa-dominant strain that bears his name was born in the late ‘80s. It combines heavyweights Northern Lights #5, Shiva Skunk, and Haze. The result is a large plant with numerous colas cloaked in sticky resin.

How long does it take Critical Jack feminized from seeds to harvest?

With autoflower seeds, growers can determine a harvest date before buying their seeds. There are some vital variables for feminized seeds, especially for outdoor grows:

- Summer length: The earlier you plant, the longer the vegetative growth before flowering occurs. 

- Flowering phase length: Outdoors flowering starts around the summer solstice on June 20/21. Critical Jack feminized should be ready to harvest 8–9 weeks later.

- First frost due date: The icy phenomenon kills crops, so leave some wiggle-room if Jack Frost comes early.

The length of the vegetative phase is a major consideration with Critical Jack feminized seeds. Outdoors, longer leads to bigger trees that should yield generously. Indoors, though, height restrictions mean you may have to shorten the phase, which could restrain final output.

Growers can count on up to five days to germinate and up to nine weeks of flowering. The vegetative phase could be anything from 5–15 weeks.

Grow medium: Critical Jack feminized hydro or soil?

Most growers agree that soil mediums enhance the flavor profile while hydroponic operations reap greater yields. Hydro is also more sterile—limiting the potential for pests.

Also, these particular Critical Jack feminized seeds produce sizable plants that may prove labor-intensive. You may even need to reduce the growing phase.

Homegrown also has autoflower Critical Jack seeds. The light doesn’t dictate when autoflower seeds bloom. Instead, the seedlings enter flowering automatically after 3–5 weeks in the vegging phase. As a result of this abbreviated vegetative phase, the life cycle is shorter. 

Critical Jack regular seeds are the original version of this strain and mainly get used by breeders wanting to create new cultivars.
