+ Speed Auto: Give Your Grow a Boost!

Speed Auto is an autoflowering cannabis strain developed by Sweet Seeds as a cross between an autoflowering Critical Mass – a fast flowering well-balanced hybrid – and Speed Devil #2 Auto (SWS25), in pursuit of creating the ultimate, rapid flowering autoflower which delivers pungent high quality cannabis.

If you want heavy yields of dense, resinous, slightly Sativa-leaning cannabis in lightning fast times, you will be more than satisfied with Speed Auto. In addition to a THC content of up to 20%, she contains an average 0.7% CBD. This versatile strain is suitable for both indoor and outdoor cultivation with indoor yields between 350-500g/m2 and outdoor yields of 30-150g/plant in a total grow time of 7 weeks from germination. Here is some further information on growing this strain:

  • Short height – this strain reaches a final height of 0.5 m indoors and 0.9 m outdoors.
  • Max EC of water – 1.0 in veg, up to 1.4 in flower.
  • Water pH: 5.8-6.0.
  • Recommended lighting: at least 450W LED.
  • Recommended nutrients: CANNA COCO range.
  • Recommended grow room temperature: avoid letting daytime temperatures exceed 28 °C.

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!

    • Advantages
      Awesome buds! A strong tranquilizing effect) Deadly potent even if not dried & cured.... Very stress resistant - I failed to feed it once in a while but the plant didn’t even notice it.) Ideal for a first time grower!
    • Disadvantages
      Yield could be better. I got 60-70g of buds. Smell is very strong - a carbon filter is a must.
    • General impressions
      A heavy hitter. Tasted it in early flowering and enjoyed its uplifting and positive energy boost. When dried and cured its effect is just deadly).

      All 4 seeds germinated at once! Light loving strain. Hungry for nutrients - even if you overfeed her she feels fine. If you use coco, the plant will reach 115-120 cm in height. Harvested on day 62. 
    • Disadvantages
      Low resistance to stress
    • General impressions
      Nice social strain. Better enjoyed with friends! Much potent than bonus AK.

    • Advantages
      The weed makes me very energetic and simultaneously very relaxed. I wouldnt describe the effects as couch-locking but just a state of relaxation with enough energy to do your work.
      It made me burst with laughs and creativity 😂
      Pretty strong buzz when you smoke it and a smell of citrus and earthy undertone. Also some cheese in the finishing 😋
    • Disadvantages
      None
    • General impressions
      I started fully inexperienced, with zero knowledge on how to grow cannabis. I chose this strain because I though it would be done fast. It was done fast for real😃
      I did many wrong moves on my ladies and they both were very healthy till the end of the grow.
      I got zero diseases, I broke the basic stem of one of my plants and after taping it healed immediately. This plant was so strong that It got taller than the other even with that amount of stress.
      Very strong strain and extremely fast (10 weeks from seed to harvest).
      My light schedule was 18-6 till the end and I didn't find any problem with the grow.
      As for the buds, they are big and thick, very very sticky with a lot of aromatic resin.😋
      It was definitely a great choice for my first grow and I am very happy for my achievement!

    • Advantages
      Great strain for beginners
    • Disadvantages
      No
    • General impressions
      This is a fab strain for a beginner, having never grown autos before and only photo's the simplicity of this strain is to place the seed in good soil and water with gentle nutes and it will do its thing for you. I think this plant just needs some very basic LST at week 3 and again each week and really thrives on its own. So if you are new to growing it's a nice no-brainer for a sweet smelling yield. 56 Days in total could have harvested sooner but wanted a heavier buzz.
      I grew these in quite large (nearly 30L) of soil which was far too much, these plants will do well in and 11L (3 Gallon) pot just fine. Im on with growing another run in these to see what the difference is.

    • Advantages
      Lots of benefits! Highly resistant to low temps. Easy to grow. Fast growing.
    • Disadvantages
      Novice growers beware! :)
    • General impressions
      Planted AK47 and Speed Auto seedlings outdoors on May 15. They survived many cold nights - sometimes the temp dropped below -4C. Started growing faster when the temp reached over +14C. Didn’t use any nutrients. Planted in organic soil when seedlings showed first round-shaped leaves. Added some root boosters. Speed Auto is now 38 days from seeding. It’s 64cm in height with a strong thumb-thick stem and started flowering already. The compact plant on photo is a bonus AK, the taller one is Speed Auto. I guess they will mature after a months and a half. 
      A fast growing strain! Resilient and resistant to low temps and minor growing mistakes. Humidity level 50. HPS lamps 150W.

    • Advantages
      Grows quicker than Jack's beanstalk.
    • Disadvantages
      With speed like that, I can't find any disadvantages.
    • General impressions
      This thing races through growth like a ferrari. I'm doing a dwarf grow in a 50cm tent. 3 3L pots. Big mistake! Fine if you've time to water and check on em every day. Its very bushy with huge fan leaves, so some defoliation, and leaf bending, and trimming is necessary for light penetration. I'm using a migro100 cob. I think I'm about day 41. Buds fattening up, but it'll be a small harvest. I'd recommend it, I fed at 1/4 biobizz fishmix, bloom and i'd topmax lying around, so that too. Check your local water analysis - it'll be on web and easy enough to find, to see what the ph is like, and look at ph after mixing. I saw a recommendation to keep ph of autos stable, but I grow in biobizz light, and they used to say it acted as a ph buffer, but now are offering ph up and down !!! More add on rubbish thats not needed. Another one is Neutralise - to remove the chlorine and chloramine - simple vitamin c powder does this for a zillionth of the cost. This plant just needs a bit of fixhmix, and bloom, and calmag for every watering.
