Genetic tree


A super reliable, highly resilient, and very easy to grow plant that boasts an impressive THC level close to 20%, with epic yields of easy to trim, citrus pine dense buds. Critical Auto is perfect for beginner growers and those who want abundant harvests of monster-sized yields in a short time. Fast Buds were able to enhance all the desired traits that make Critical so popular, resulting in a medium tall plant that performs incredibly well in hot climates. Despite her Indica dominance, Original Auto Critical is perfect for social scenarios and provoking creativity. The best choice for commercial growers and amazing for hash and extracts.

Bud description

The buds will be compact, yet have a large mass meaning they have the ultimate bag appeal. Upon first inspection, you will notice calyxes bulging with a density that can be squeezed with force. Critical Auto will flower with a golden hue from the pistils that are oozing resin making her a hash makers delight.

Smoke report

After lighting a joint, there will be an immediate effect that is deeply relaxing. A balanced hybrid that will provoke creativity as well as a physical body effect that is both calming and serene. A great choice for social nights out, musicians, artists, gaming, or chilling with friends watching movies. Be warned that smoking too much can leave you in a dream state that can last for hours.

Plant Appearance

When growing, expect plants to reach a height ranging between 90-140cm, meaning growers with limited space may have issues. Critical Auto will grow short compact internodal spacing that will produce dense nugs at every internode, making her a heavy yielding variety (450-600gr/m2) that may require plant support. Outdoors this girl performs incredibly well and especially in a Mediterranean climate, where she will grow with a Christmas tree growth structure that is full of dense, frosty buds at every branch.

Grow Tips

She can be harvested multiple times in a year outdoors and will not require much plant maintenance. Because Original Auto Critical is known for her large yields, using a bamboo cane or a trellis to support the weight of the buds early on is advised. Training this strain in the early stages of growth will increase the number of flowering sites, enhancing production even further! Due to her large size, training is especially important in cases where space is limited.


When smoking Critical Auto the flavor can be described as a delicious blend of lemon, citrus, and pine, with an earthy aftertaste. On the exhale, there is a strong floral, citrus flavor that is long-lasting and can be enjoyed with every toke. A very unique taste that old school and new school growers will love.

Happy with my Critical
From the originals line I have grown this one, Sour Diesel, Amnesia Haze, and Northern Lights. I have really liked all of them, I don't think I could choose a favourite.

I got bud rot :(
The flowers grew really big and fat, which is great, but I wasn't expecting to see bud rot on it. I did grow it outside so I guess this is the reason, but I'm just so sad about it...

Bud rot is from moisture. Hot days and cool nights causes condensation and rot happens quickly.

Fun grow
This was a lot of fun. I did a. lot of training so she went a little longer in veg. She's a bit of a heavy feeder but very easy to grow and a strong strain. Nice smooth pine flavors. I will grow again soon.

I got this as the free seed in my order
I didn't know what to expect with this one as I hadn't read up about it much, as I didn't actually buy it I got it free, but I'm more than happy. It was very easy to grow and it grew quite big. I'm think of making a new order and getting another pack of this Critical, maybe I'll try some others from the Original line too. Thanks fast buds!

Is the soil type and the ph important and does it vary according to which seeds I use thanks
Hello, the type of substrate you use isn't very important but the pH is. You can definitely have good results without measuring the pH levels but for the best results possible you should check the pH of the nutrient solution and make sure it's within the acceptable range for the substrate you're growing in. Remember that the pH varies according to the substrate and not the strain.
