Excellent Bud-to-Leaf Ratio

Those who are familiar with Critical Mass will appreciate the complexity of the smell and taste of Speed Auto: her tightly formed pale green buds have a high calyx-to-leaf ratio which makes trimming a breeze! Her great visual appeal comes alongside a pleasant, uplifting high which boosts creativity!

  This is a fabulous strain for a beginner who has never grown autoflowering plants before. The only downside is that the simplicity of this strain is to place the seed in good soil and water it with mild nutrients, and it will do the work for you. I think this plant just needs very basic LST (Low Stress Training) in week 3 and then every week thereafter, and it really develops on its own. So, if you're new to growing, this is a great choice for a fragrant yield. It took 56 days to harvest, but I wanted a more intense high.
  I grew them in a fairly large pot (nearly 30 L), which was way too much; these plants will do just fine in an 11 L (3 gallon) pot. I'm growing another crop in these to see what the difference is.

- Disadvantages

- General impressions
  
  Planted AK47 and Speed Auto seedlings outdoors on May 15th. They survived many cold nights—sometimes the temperature dropped below -4°C. They started growing faster when the temperature rose above +14°C. No nutrients were used. Transplanted into organic soil when the seedlings showed their first round leaves. Added some root boosters. Speed Auto is now 38 days from seed. It is 64 cm tall with a solid stem about an inch thick and has already started to flower. The compact plant in the photo is a bonus AK; the larger one is Speed Auto. I expect them to mature in about six weeks. A fast-growing variety! Resilient and tolerant of low temperatures and minor growing errors. Humidity level 50%. 150W HPS lights.
