1. History

The history of the Chemdawg strain starts in the early 90s where a group of cannabis breeders from Colorado were following a band on tour and took some of their weed with them, they had named this weed “chem bud” due to the unique chemical and diesel flavors.

When they got to one of the shows, they sold a couple of grams to a group of friends who quickly realized those were some special buds and, lucky for them, the buds had a couple of Chemdawg seeds (before they actually knew what they were) which they stored.

When one of the friends, who was also a cannabis grower, went back to his home on the East Coast, he germinated some of the seeds and started selecting the best phenotypes to continue developing those genetics even further.

As you may know by now, his effort paid off, and soon enough there were two versions of this strain going around, one was Indica-dominant and the other was a Sativa-leaning hybrid.

Both of these versions quickly spread around and several breeders developed new strains with these genetics, getting known by almost every cannabis consumer, becoming extremely popular and giving birth to a lot of famous strains such as Sour Diesel and OG Kush, although this isn’t confirmed, several old-school growers swear by it.

2. Specifications

These precious genetics were boosted by the Fast Buds team to provide a super tough, potent, and easy-to-grow strain.

Our Chemdawg Auto from our Originals line grows around 90cm and is very resilient to diseases and colder climates but watch out because if you’re growing outdoors, your neighbors will be able to smell it easily.

This strain can be cultivated even by beginner growers due to it requiring minimal maintenance and can produce up to 400gr/m2 in 8-9 weeks, this is one of the shortest varieties we have to offer and can be the perfect choice for those growing on a balcony or in a limited grow space. 

As soon as the trichome production starts, you can expect a terpene profile that resembles a mix of chemicals that is a delicious blend of diesel, gasoline, and petroleum.

With up to 20% THC, you can expect a super potent high that will take you into another world and leave you there, while you relax with a strong corporal high that will leave your whole body melting, a perfect effect to relax after a long day of work or inducing a good night of sleep.

3. Week-By-Week Guide

This post serves as a general guideline on the conditions kept throughout this grow cycle, our week-by-week serves to give cultivators an idea of what to expect when growing this flavorful genetics.

 

Grow Specifications
Light Fixture: LED
Light Cycle: 18/6
Humidity: 50-75%
Temperature: 20-27°C
Grow Space: Indoor
Nutrients: Synthetic
PH level: 5.8-6.5
Seed to Harvest: 8-9 weeks

 

Remember that this timeline has been written to help you and the results may differ depending on your ability to grow cannabis and the conditions provided, have in mind that you should adjust the conditions depending on your growing setup.

Week 1 - Germination

Week 1 is where this grow journal starts, the growers started by germinating the Chemdawg Auto seeds directly into the soil and in a few days the seedlings came out of the soil, but the grower fed them with a light nutrient solution which was too much for the fragile seedlings and they presented minor signs of nutrient deficiency.

 

Height: 2.54cm
pH: 6.0
Humidity: 50%
Temperature: 26°C
Watering: 100ml

 

Have in mind that this isn’t the germination method we recommend but if you’re not a beginner and know what you’re doing, there shouldn’t be a problem at all as long as you maintain proper conditions which should be a temperature between 18-25°C and a relative humidity of around 70%.

 

Chemdawg auto guide: week 1

First week of growth by Cbalderson601 and ROM1012.
 

This week starting out rough. I thought full seedling strength would be fine to start since my medium has no nutrients in it I was wrong. Showing signs of nute burn so i did a small flush -Cbalderson60

As you can see, the seedling has the leaves tips yellow due to overfeeding, now, this will not cause problems because they were burned lightly but if the nutrients dose was stronger, it could end up killing the seedling.

Week 2  - Vegetative stage

After your plant has developed the first pair of true leaves, you can go ahead and start feeding Grow nutrients in a 3-1-2 ratio, meaning the feeding should contain mora nitrogen which is the macronutrient cannabis plants need to develop green matter such as leaves and stems,  just have in mind that you should start with a lower dose to avoid overfeeding.

 

Height: 5cm
pH: 6.0
Humidity: 50%
Temperature: 25°C
Watering: 200ml

 

This week was great. Once she received the proper watering and nutrients she bounced back with no problems. I also backed light up 2 inches. She is healthy now (new growth) and a good resilient strain so far no signs of stunting. Real compact plant too showing 4th node and only 2 inches tall. -Cbalderson60


As you can see from the grower´s comments, after flushing, he started feeding again and his plant recovered with no problems, remember that to avoid problems you should check the pH and PPM if possible, this is the best way to avoid nutrient lock.

 

Chemdawg auto guide: week 2

Second week of plant growth by Cbalderson601 and ROM1012.
 

As you can see from the photos, the plant has not shown any more symptoms of nutrient deficiencies and is now looking perfectly healthy.

Remember that cannabis plants need a couple of days to recover from stress so by providing the best conditions that you can, your plant will recover and continue to grow with no problems at all.

At this stage, you should check and adjust the growing environment to be at  18-25°C and a relative humidity of around 65%.

Week 3  - Vegetative stage

By week 3, the roots should have established and you will see new growth day after day, if you wish to apply any form of plant training, now would be the best time to do it, although this strain develops a short internodal space you should think about what will work best with our Chemdawg Auto.

 

Height: 7.6cm
pH: 6.0
Humidity: 50%
Temperature: 25°C
Watering: 300ml

 

A Lot has happened this week. Let's start out with the light I'm using it lacks red. She wasn't growing the fastest. Also I wanted to get bigger leaves and stretch that's where red comes in.... I decided to do lst this week she a small one though. I almost just let her grow but more tops more yield -Cbalderson60

As said above, due to the short internodal space it may be hard to tie down the branches but if you do it properly, you will benefit from it so the grower decided to go ahead and try it.

When applying any form of plant training, even low-stress training, it's vital you do it slowly and carefully because you don't want to stress your plants, as you may know by now, cannabis plants need some time to recover and when talking about autoflowers, it can end up ruining your harvest because they have a limited lifetime.

Week 4  - Vegetative stage

The fourth week marks the week before the pre-flowering stage and by now you will see the flowering sites slowly turning light green, as you will in the images further down, the grower tied the branches to expose all of the flowering sites so the light can reach them equally.

 

Height: 12.7cm
pH: 6.0
Humidity: 50%
Temperature: 25°C
Watering: 500ml

 

A lot of growth happened this week. She is transitioning to flower. I have been tucking leaves and lsting her for the last two weeks. I was able to get 8 to 9 colas come up. She is a short one though. Hope the stretch will get her over a ft tall will see -Cbalderson


If you´re growing feminized seeds like the ones being grown in this grow journal, there's no need to worry but if you´re growing regular seeds (meaning they can be male or female) you should keep an eye on all of your plants because male plants will develop pollen sacs and can end up pollinating all of your buds, producing seeds.

 

Chemdawg auto guide: week 4

Also, it's completely normal for the flowering sites to turn light green at this stage, if this was happening during any other part of your plant´s grow cycle you should worry but if you´re nearing the pre-flowering stage it's completely normal, it's a sign that your plant is getting ready to develop stigmas which are the white hairs that appear when your plant is starting to flower.

Week 5  - Pre-flowering stage

The fifth week marks the pre-flowering stage and this stage marks the transitioning from the vegetative to the flowering stage. 

As soon as you see the first stigma appearing you should slowly start feeding a low dose of Bloom nutrients because after the first stigmas appear your plant will start to develop the flowers and Bloom nutrients provide Phosphorus and Potassium which are the macronutrients your plant needs at this stage.

 

Height: 30cm
pH: 6.0
Humidity: 79%
Temperature: 23°C
Watering: 800ml

 

This week was just to feed her and let her grow. I didn't do any training this week. She’s stretching nicely...Hope to get a bit more stretch out of her next week then defoliate towards the end just to get more light to bottom. -Cbalderson60

As you can see in the pictures, white hairs started developing all over the flowering sites, now, this may take a while with other strains but this one grows relatively faster so from a week to the other the growth is easily visible.

As the grower commented, at this stage you should stop training your cannabis plant because it may end up stressing her and at this stage, it can compromise the yields so make sure that you don’t do it and if you do, do it very carefully.

Week 6  - Flowering stage

By week 6 from germination, your plant is in full-flowering mode and it should be reeking of a delicious smell but unfortunately, not everyone enjoys it so you should get your carbon filter and exhaust fan ready to install if you haven’t already.

 

Height: 38cm
pH: 6.0
Humidity: 74%
Temperature: 24°C
Watering: 1000ml

 

She is officially in the early stage of bloom when flowers are forming. I did a little defoliating this week just a few leaves here in there just to get more airflow through her and light. Also, feed her grow nutrients halfway through this week then dropped to 1/4 tsp. I'm trying to get this short autoflower as big as I can. -Cbalderson60

 

The smell is due to the trichomes that should already start to appear in abundance, the trichomes are where the terpenes, cannabinoid, and flavonoids are produced and stored so the more trichomes your plant produces, the stronger the smell.

 

Chemdawg auto guide: week 6

Usually, the sweet weed smell attracts all types of bugs so if you’ve grown in the same space before and have had problems with bugs, it’s better to take preventive measures to avoid them and finish your grow cycle without any kinds of problems.

So you can place yellow sticky traps all over or spray your grow tent with a bit of organic insecticide to prevent, also, it’s essential you keep the humidity at the right levels because buds are mostly made out of water and if the humidity increase drastically, you may end up with bud rot or powdery mildew.

Week 7  - Flowering stage

The seventh week marks the second half of the flowering with our Chemdawg Auto, by now the buds should be almost completely formed and you will see a lot of resin all over the buds and surrounding foliage.

 

Height: 43cm
pH: 6.0
Humidity: 59%
Temperature: 22°C
Watering: 1200ml

 

Have in mind that apart from the macronutrients, cannabis plants also need micronutrients (aka “trace elements”) which are also essential but needed in much smaller amounts so depending on the type of medium you’re growing in, you should provide them.

These micronutrients can be easily found in grow shops and usually come as a supplement that provides Calcium, Magnesium, and other important trace elements.

As you can see, the buds look like they’re ready to be chopped but don’t get anxious, even though the buds are dense they will get even denser so be patient, there’s only a couple of weeks left.

Week 8  - Flowering stage

Week 8 from harvest marks the week before the last an should be extremely frosty, with some of the stigmas already turning brown but wait, the standard practice to harvest at the correct time is to check the state of the trichomes so even though some of the pistils may be turning brown, don’t harvest yet.

 

Height: 44cm
pH: 6.0
Humidity: 51%
Temperature: 21°C
Watering: 1300ml

 

To see the trichomes clearly you will need a jeweler’s loupe or a microscope but don’t worry if you don’t have one, you can use your phone's macro mode, even though it won’t be the same it should give you an idea.

Also, depending on the type of nutrients you’re using (synthetic or organic), you should think about starting the flushing process, flushing will remove the excess nutrients on the roots and medium and will result in a smoother smoke, better flavor, and stronger aroma.

As you can see in the photos, some stigmas have already turned brown and the plant looks ready for harvest but as you will see in the next week (which is the last) the buds still have to ripen and fatten up a bit more.

Week 9  - Harvesting

This is the last week, you’ve made it. At the end of this week, you’ll be harvesting your long-awaited Chemdawg Auto, now, if you’ve already started the flushing process most fan leaves can start to yellow and die but don’t worry, this is a sign that you’ve flushed properly.

 

Height: 44cm
pH: 6.0
Humidity: 51%
Temperature: 21°C
Watering: 1400ml

 

As specified in the second topic, this strain grows around 90cm but due to the training performed, it stayed at 43cm, now, this shouldn’t be a problem at all because if you LST properly, all the buds should have received proper light and should be really dense and covered in resin.

 

Chemdawg auto guide: week 9

Now that your plants are ready for harvest you can clearly see how the bigger fan leaves have yellowed and how most of the stigmas are brown, at this stage you should think whether you prefer a cerebral effect or a more corporal one, and depending on which one you want, you should harvest accordingly, remember that cloudy trichomes provide a more cerebral high while amber a more relaxing body effect.

4. What To Expect?

Now that your plants are already drying you’ll only have to wait a couple of weeks before smoking them for the first time, but if you are curious to know what to expect, here are our growers’ reports.

As you may have smelled throughout the growing cycle, this is a true representation of chemical, gassy, and diesel terpene profiles thanks to the following main terpenes:

  • Pinene
  • Humulene
  • Myrcene
  • Caryophyllene

Our Auto Chemdawg effects is a fusion of chemicals with earthy essences that will leave a long-lasting gassy concoction in your mouth with a kushy aftertaste.

The terpene blend results in a 80% Indica and 20% Sativa effect that provides a nice sense of relaxation and can alleviate pain,  growers have reported feeling creative,uplifted and an overall happiness with the negative effects only being a really dry mouth.

5. In conclusion

If you’re looking for truly gassy genetics, this strain is a must for you! The good blend of Indica and Sativa genetics provides a really pleasant high that will leave your whole body melting and will put you in a cannabis coma, perfect for after a long day of work or when you want to relax or meditate.
