Jack Frost: Jack of All Trades

Jack Frost’s blend of bright citrusy sweet flavor with a woody, earthy undertone that is unmistakable. With so many strains smelling and tasting the same its nice to have one that really stands out in the crowd. The balanced hybrid has more sativa-heavy features than Indica.

The Indica undertones offer you a relaxed feeling without pinning you to the couch or making you retreat to the safety of your home for the day. It is ridiculously well-balanced and a great choice for wake-and-bakers. It is also a prime example of a beginner friendly bud when it comes to growing. Jack Frost isn’t fussy and isn’t time consuming. Once you get your seeds dialed in, the grow produces solid yields and a THC content that is higher than average.

Growing Tips for Our Seeds

The Jack Frost strain grows taller than most so carving out a grow site with lots of headroom is a must. Standing at over 6 feet tall when fully grown you are going to need an outdoor grow where the sky’s the limit or an indoor grow with high ceilings. You could even use a tent as long as the tent is 7 or more feet above floor level. The strain is known for being low-maintenance and also resilient, resistant to mold and disease, thriving in most environments. Jack Frost is one of the unique strains that actually requires a mild, cool climate as opposed to hot, humid environments like many other strains require. You can grow this strain outdoors almost anywhere. The grow cycle for this particular strain is pretty average, but it is the hand-off approach you can take to this bud that makes it feel shorter than most.

Dial in Your Growing Conditions

  • Indoor or Outdoor: Jack Frost plants will perform great in a cooler environment. Ideal growing conditions for Jack Frost plants require a temperature range between 70 and 75 degrees Fahrenheit. To maximize your yield and THC content you are going to want to stick to a strict 12 hours on 12 hours off light cycle. This cycle will trigger the plant into its flowering stage without much effort on your part.
  • Moisture control: The humidity needed to grow the Jack Frost strain is ideally, around 50-60% during the vegetative stage. Drop the humidity to 40-50% when approaching the flowering stage. This will keep mold and mildew off of your dense buds.
  • Training Techniques: Jack Frost plants can be trained using Topping and Low-Stress Training techniques. These techniques will help your plants get adequate light from top to bottom. Pruning off any yellow or dying leaves is crucial to ensure each individual bud gets the right light to grow into a healthy, smokable bud come harvest time.

The Germination Game Plan

Before you even plant your Jack Frost female cannabis plants, you will first need to germinate these seeds. To do so, refer to our free germination guide, knowing that they are backed by our impressive 90% germination guarantee.

Yields, Flowering Time and Harvest

  • Flowering Time: With an indoor grow you can expect the Jack Frost strain to harvest after its flowering stage of 9-11 weeks. If you planted outside then you can expect to harvest in October, so make sure that you plant them with that time frame in mind
  • Yields: Indoor yields are around 450 grams per square meter, while outdoor grows typically produce over 550 grams per plant. Both indoor and outdoor yields are larger than average. The longer flowering time is what helps improve yield size and will leave you with dense, rich buds that are worth the near three month waiting period.

Dominant Terpenes in Jack Frost: Frosty Nugs

The Jack Frost terpene profile is directly responsible for how this plant smells, tastes and what effects it has on its users. The most dominant terpene in this strain is Terpinolene while myrcene and caryophyllene are in the background contributing to the taste and how it affects the user.

  • Terpinolene: Most Dominant– This terpene has a fruity yet floral bouquet. It is also found in apples and lilacs.
  • Myrcene: Calming Properties- Found in hops, lemongrass and, you guessed it, cannabis, Myrcene helps with insomnia and anxiety.
  • Caryophyllene: Peppery Aroma – The Caryophyllene in Jack Frost can help support your immune system and digestion.

Dominant Cannabinoids in Jack Frost:

Cannabinoids, although in the background, play an important role in Jack Frost and are generally a huge part in the makeup of cannabis. That creative, relaxed and even talkative and uplifting feeling you get when using Jack Frost is due to its dominant cannabinoids. Each cannabinoid does something a little different.

  • THC: The Main Character – THC is the most dominant cannabinoid on the molecular level of Jack Frost. The crystalline compound tetrahydrocannabinol is the main ingredient of cannabis. Topping out at a healthy 21%, the THC in the balanced hybrid is responsible for how this strain makes users feel.
  • CBG: Small Amounts – While the CBG levels in Jack Frost are slightly less than 1% it still plays a small role in what the strain does to the user. CBG, even in the smaller doses featured in Jack Frost can help with its uplifting effects and othe medicinal properties

    These seeds produce plants with buds that are as frosty and sparkling as freshly fallen snow. The aroma is crisp and refreshing, like a breath of icy air on a snowy day.

  8. bagillies3620 Verified Buyer

    Really cool strain as it has a decent amount of CBG in addition to THC. Grew well in my tent setup. Bushier plants than I expected but nothing that pruning at the right time couldn’t fix. Great strain if you need to focus on weird bits of minutiae.

  9. LEDLoverX Verified Buyer

    Support replied fast when I messaged about a mislabeled pack, but it took them 6 days to actually ship the right one out.
