Germinating cannabis seeds

It is important to germinate your weed seeds carefully if you want to have a healthy harvest from day one. Although there are several methods to germinate our Feminized cannabis seeds, at Blimburn Seeds, we recommend our customers to follow our easy and simple technique.

Before removing our Key Lime Jack seeds from their packaging, remember that cannabis seeds are alive and delicate. Our hands are full of bacteria that can easily infect seeds and ruin our germination.

Set Up Your Germination Station: Begin by moistening two paper towels with room temperature water. Lay one paper towel on a plate and spread the seeds on it, spacing them about 2 cm apart. Place the second paper towel on top of the seeds, and make sure to remove any excess water from the plate. Cover the setup with another opaque plate and store it in a warm, dark location.

Monitoring: Make sure paper towels are still moist by checking every 4-6 hours and spraying room temperature water. Typically, germination should occur within 24 to 120 hours. Once the seeds have sprouted tap roots, plant them with the roots facing down and cover with about 2 cm of soil.

Remember to water the soil regularly by spraying to keep it moist. It may take up to two weeks for the plants to start growing.

Ideal Conditions: Maintain a consistent temperature of 69.8 ºF – 78.8 ºF (21 ºC – 26 ºC) in the germination area. Use purified room-temperature bottled water with a pH level between 5.5 and 6. Keep the seeds away from light, allowing exposure for less than 1 minute before and during germination. Avoid touching the seeds or applying pressure to them.

Record Keeping: To qualify for the three month germination guarantee, it is necessary to follow all the steps outlined in our germination guidelines. Please do not use alternative germination methods, such as using a water bottle or planting directly into soil. Document the germination process through photography or video, as it will be requested when assessing claims for replacement products.

During this period, the plants develop thick, resin rich buds with a distinctive citrus aroma, reflecting their lime forward terpene profile. The flowering phase rewards cultivators with dense and flavorful yields.

If on the other hand you like to grow your Feminized seeds indoors and you have good tents, textile pots for growing, led lighting, air extractor, to circulate clean air and of course a good carbon filter to avoid problems with neighbors or the law.

These Feminized plants need low humidity to thrive. Keep relative humidity (RH) levels at 55%-60% during the vegetative phase. Reduce RH to around 40% during the flowering phase. By harvest time, you can reduce RH to 30%.

Outdoors, breeders in the northern hemisphere should sow their cannabis seeds in April for harvest in mid October. Healthy Feminized Key Lime Jack strain produce about 15 – 17 oz/plant | 450 – 500 gr/plant of buds each.

Indoors, these crops have a flowering time of 8 – 9 weeks and produce about 1.64 – 1.82 oz/ft2 | 500 – 550 gr/m2.

Ideal Climate for Growing

The Key Lime Jack strain flourishes in a warm, sunny climate typical of Mediterranean and temperate regions. The ideal temperature range for cultivating this strain is between 70–85°F (21–29°C), which promotes vigorous growth and robust yields. This variety also benefits from well draining soil and plenty of sunlight, making it essential to provide at least 6-8 hours of direct sunlight daily. Moisture control is crucial, as Key Lime Jack prefers moderate humidity levels to prevent mold and mildew.

These regions offer the warm temperatures and ample sunlight essential for this strain’s success.

What does the strain smell like?

The buds of Key Lime Jack are rock hard, soaked in resin and carry a crystalline sheen from the heavy coat of trichomes. The flavor is a blend of citrus, lime, pine and herbal notes.

Key Lime Jack makes a smooth, soft smoke and combines a wide range of effects for a balanced experience, blending indica and sativa. Thanks to its high resin production, it is a good choice for high-quality extracts and concentrates.

A good terpene profile enhances the flavors of the buds of cannabis plants. Terpenes are volatile organic compounds that are produced in the cannabis plant and have an effect on the aroma and flavor of the buds.

These terpenes act as a kind of energizer for the flavors of the buds, as they add a fresh, citrusy touch to the sweeter flavors found in the buds. On the other hand, terpenes also have an effect on the effect that cannabis produces when smoked, as some terpenes have sedative properties, while others can act as stimulants.

For this reason, it is important to know the different terpenes found in a given cannabis strain before smoking it, in order to get the most out of the flavors and effects they produce.

Key Lime Jack Terpenes

Key Lime Jack leads with a bright, zesty lime-and-citrus aroma layered over crisp pine and a green, herbal edge, a fresh, uplifting nose inherited from its Key Lime Pie and Jack Herer parents. Beneath those top notes sit two dominant terpenes that shape the strain’s depth and drive its euphoric, happy, relaxed balance, each adding a different layer to this 50/50 hybrid.

Myrcene anchors the profile with a deep, earthy-musky base carrying a soft, herbal undertone that grounds the zesty top notes. Widely associated with deep relaxation and physical ease, it drives the soothing, body-calming side that keeps the balanced high from tipping too far into cerebral territory.

Caryophyllene adds a warm, peppery, faintly herbal-spicy bite that gives the aroma structure and contrast against the citrus brightness. Often tied to easing tension and everyday stress, it lends the calm, grounded quality that pairs with the strain’s uplifting, focus-friendly side.

Together, these two terpenes give Key Lime Jack its signature contrast: a fresh, lime-and-pine aroma over an earthy, peppery base, paired with a balanced, uplifting-yet-relaxing experience that works at any time of day.
