Growing Tips for Critical Jack Auto
Critical Jack Autoflowering cannabis is an easy-to-grow strain that is preferred by novice growers. Critical Jack Auto marijuana plants will thrive indoors and outdoors, but have an easier time growing indoors because of the ability to completely control the climate. If you choose to grow indoors, you will have to replicate a steady environment similar to the climate of the Mediterranean. Critical Jack Auto cannabis seeds grow bright green plants with yellow pistils and resinous trichomes covering the bud sites so much that the buds appear yellow. If you choose to grow outdoors, you will need to hope for consistent temperature and humidity to grow these plants to completion. Doing so will ensure that you grow healthy buds from the top of the plants to the buds closest to the soil. Having access to a greenhouse is the best way to give these plants the perfect outdoor climate without having to put up with unexpected outdoor variables. These plants grow to a medium height and can reach around 3-5 feet tall. Because the plants reach a maximum indoor and outdoor height of 5 feet, they will need to be trimmed so they continue to fit in your grow area. The ideal temperature for these plants is around 70-79 degrees Fahrenheit and slightly cooler at night. Humidity levels should be kept around 40-60% during the vegetative growth stage and the flowering stage, but lowering the humidity every week will help this plant grow. Growing indoors will ensure that the moderate humidity levels and moderate temperatures are constant and maintained every day that the plants are in the growing stages. Pruning and low-stress training (LST) methods will help these plants grow correctly. Each method will help the plants maintain the desired shape and height. The Critical Jack Auto strain requires an 18-hour light cycle to reach the vegetative stage of growth. You do not need to change the light cycle to induce the flowering phase of growth.
Yields, Flowering Time, and Harvest
- Flowering Time: Growing indoors, you can expect the Critical Jack Auto strain to harvest after a short flowering period of 50-60 days.
- Yields: While Indoor yields are around 500 grams per square meter, outdoor grows typically produce up to 800 grams per plant. These yields are absolutely massive and will keep the grower flush with buds for a long time after harvest.
- Harvest: Outdoor growers can plan on harvesting their yields around the beginning of October, depending on when the seeds were planted.

Easy to grow and yielded high-quality buds. The plants were resilient and adapted well to various conditions. The smoke has a rich, cornbread-like flavor with earthy undertones.
Super fresh herb! Gets me nice and stoned and usually is a gem in the yard. Vibrant colors and usually a nice sticky resin on top. I buy online to get the most bang for my buck!

Nothing says “I love weed” like buying your own mj seeds online! I personally recommend this strain cause it’s a little easier to grow than most other strains, and it hits real nice! An indica heavy strain for sure, usually good for smoking in the evening, when I am already tired. Helps soothe those aches and pains, and quiets the mind.
Make no mistake, this weed WILL change your life. The smell and taste of this strain is unlike any other. The nugs themselves are sweet and fluffy. They look GREAT! I smoke it every morning, and every evening too. It’s an anytime smoke. Fun times and great vibes!!
I opened up the packet, 3 seeds all perfectly tucked away inside. Like little marbles ready to be put into the ground. Impressed by the fast shipping times Pacific offers their customers, and by the incredible looking marijuana I was able to produce. Can’t wait for that next harvest, gonna be a big one.
