How To Grow Auto Critical?

Critical Autoflower seeds can be grown indoors or outdoors under optimal conditions, to avoid any problems during their development. Although they are compact and robust, moderately easy to grow and hardy, we should always prevent any pests.

You can use different growing methods to retain and enhance the terpenes and flavors of your Critical Auto buds.

• Use a quality substrate. Perlite, peat or coco coir are ideal for moisture retention.
• Thanks to the experience of our customers with our  Critical Autoflower seeds, we know that we can increase yields up to 20%.

Autoflower cannabis seeds are a very popular strain among cannabis growers. They are known for their fast life cycle and their ability to flower automatically after a set period of time, rather than relying on changes in the light cycle like other cannabis strains.

As for the hours of light needed, Autoflower weed seeds can grow and flower with as little as 12 hours of light per day. Unlike other cannabis strains, they do not need a specific amount of light to go from the vegetative cycle to the flowering cycle. We recommend 18/6 or 20/4 to obtain Medium yields. This means that growers can have greater control over the growing process and can create an optimal environment for their plants without having to worry about light time.

However, it is important to ensure that the plants receive enough light for healthy growing, as the quality and quantity of light can affect the plant’s yield and growing. Another advantage of Autoflower seeds is their fast life cycle. These plants can grow and flower in as little as 8-10 weeks, which means growers can harvest several times a year.

Also, autoflowering seeds tend to be smaller and more compact than other strains, making them ideal for growing in small spaces or indoors. As for the quality of the marijuana produced by Auto seeds, it is important to keep in mind that genetics and growing conditions also play an important role.

However, many autoflowering cannabis strains have won awards for their taste, aroma and effects, proving that these plants can produce high quality marijuana. Remember that our cannabis plants also need good nutrients when our Autoflower seeds are seedlings, in their vegetative period and finally in their flowering period.

When you grow cannabis seeds outdoors, choose the best date for your crop, a place where our cannabis plants receive the most hours of sunshine. If on the other hand you like to grow your Autoflower 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.

Keep daytime temperatures between 68℉-80℉ and nighttime temperatures between 7℉-9℉ cooler.

Autoflower 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: In the Northern Hemisphere, growers should sow their autoflowering cannabis seeds in April, achieving a first harvest in mid summer and a second harvest between July and mid October. Healthy Critical Autoflower seeds produce about 21 – 24 oz/plant | 600 – 700 gr/plant of buds each.

Indoors, short life cycle of 8 – 10 weeks and produce about 1.15 – 1.32 oz/ft2 | 350 – 400 gr/m2.

Ideal Climate for Growing

Critical Auto strain thrives in a temperate climate, ideally characterized by consistent sunlight and moderate humidity. The optimal temperature range for cultivation is between 70-80°F (21-27°C), which promotes healthy growth and flowering. This strain is quite adaptable, but ensuring stable temperatures will enhance its yield and overall potency. For best results, aim for annual precipitation of around 20-30 inches (500-760 mm), while providing well draining soil to prevent waterlogging.

Cannabis seeds are sold for collection and genetic preservation. Check the law in your country before germinating them.
