How to Grow Chemdawg 4 CBD
Chemdawg 4 is royalty: the selected fourth seed of the Chem line that fathered half of modern American cannabis. This version, listed as CBD Chemdog #4 at Blimburn Seeds, keeps the legendary genetics and dials the chemistry down to a gentle 1:1 ratio of 6-7% THC and 6-7% CBD, the softest member of the whole Chem family.
Interestingly, the flavor moved the opposite direction from the name. Where the classic Chem profile leans diesel and funk, this cultivar expresses the brighter side of its inheritance: lemon, citrus, pine, sweet and woody, like the forest edge of the Chem genome with the fuel turned off. Growers who want the original experience can still find the family patriarch as Chemdog Regular.

| Type | CBD Feminized (photoperiod) |
| Lineage | Chemdawg #4 x CBD |
| Phenotype | 55% Indica / 45% Sativa |
| CBD / THC | 6% – 7% CBD, 6% – 7% THC (1:1) |
| Climate | Temperate |
| Height | Up to 4.92 ft (1.5 m) |
| Flowering time | 8 – 10 weeks after the flip |
| Harvest month | October |
| Yield indoor | 1.15 – 1.31 oz/ft² (350 – 400 g/m²) |
| Yield outdoor | 3.53 – 5.29 oz/plant (100 – 150 g/plant) |
| Effects | Happy, relaxed, uplifted |

Indoors, 350-400 g/m² is honest, steady production for a plant this easygoing. Outdoors, 100-150 grams per plant tells you this cultivar holds back without the controlled conditions of a room or greenhouse, so plan it as an indoor project from the start and the numbers will never disappoint you.
Promos & Deals
Getting CBD Chemdog #4 Started
Germinate at 70-79°F using paper towels or starter plugs; taproots show within one to three days. Pot up progressively to a 3-5 gallon final container. Every feminized seed flowers female, and the seedlings carry the Chem family’s trademark vigor: fast, slightly stretchy early growth that settles once the frame fills out.
Veg under 18 hours of light at 68-81°F with humidity around 50-60% for three to four weeks. The 55% indica build produces a balanced plant with solid branching, and the forgiving temperament behind its beginner rating shows early; it shrugs off the small errors that mark fussier genetics.
Feeding CBD Chemdog #4 by EC
Chem-family plants feed confidently but hate excess late in bloom. Work by EC, keep pH at 6.0-6.5 in soil, and taper early rather than late.
| Stage | Weeks | EC | Notes |
|---|---|---|---|
| Seedling | 1-2 | 0.4 – 0.6 | Plain water or very light feed |
| Vegetative | 3-4 | 0.8 – 1.2 | Nitrogen-leaning base nutrients |
| Preflower | Flip + 1-2 | 1.2 – 1.4 | Transition feed through the stretch |
| Bloom | Flip + 3-8 | 1.4 – 1.6 | Bloom base, add PK booster |
| Flush | Final 1-2 | 0.0 – 0.4 | Plain pH-corrected water |
Hold the middle of the bloom range and watch the leaf tips; this cultivar signals overfeeding quickly and recovers just as fast if you respond. Supplement calcium and magnesium under LED lights, and let the natural late-bloom fade proceed without fighting it.
The flush earns its keep here. Lemon and pine are among the most fragile notes in cannabis, and two clean weeks of water are what keep them bright in the jar.
Training CBD Chemdog #4 and Flipping to 12/12
Top once above the fourth node in week 2 or 3, then shape with low-stress training into an even, open canopy. The branches bend easily and hold position well, and with modest yields per plant, maximizing lit bud sites is how you reach the top of the indoor range.
Flip to 12/12 when the canopy covers about two thirds of the footprint. The stretch is moderate, flowering runs its 8-10 weeks predictably, and the buds develop the classic Chem structure: medium-dense spears with generous resin. Keep humidity at 40-45% from mid-bloom with steady airflow, standard discipline rather than special treatment.
Harvesting and Curing CBD Chemdog #4
Start reading trichomes at week 7 of flower and harvest at full cloudy with the first ambers. With a gentle 1:1 ratio, timing is about keeping the lemon-pine brightness at its peak rather than chasing chemistry shifts, and the cloudy window delivers both. Outdoors in a temperate climate, the plant finishes in October.
Dry for 10-14 days at 59-68°F and around 55% humidity, then cure in glass for at least two weeks with daily burping early on. The pine settles first, the lemon sharpens through week two, and the sweet woody base ties them together by week three. It is a quieter jar than the diesel Chems, and a far more refreshing one.
What to Do With Your Trim
Balanced 1:1 trim at this gentle level is ideal kitchen material: infused oil or butter delivers mild, manageable edibles with the citrus-pine character carrying through. Hash makers get modest but clean returns. Process within a few weeks of harvest while the lemon notes are at their best.
Aroma, Flavor and Terpenes
Two terpenes anchor a five-flavor profile, and the math works better than it sounds. Pinene is the headline, delivering the pine and woody notes directly while lending the whole profile the fresh, resinous clarity that makes the citrus impression pop. Humulene works underneath with its dry, earthy, faintly hoppy depth, keeping the brightness grounded.
The lemon and citrus themselves are the Chem inheritance expressing through the blend, the same lemony edge that always lurked behind the fuel in Chemdawg 4, finally given the spotlight. Sweetness rounds the exhale. It is a simple, clean arrangement that cures into something far more elegant than the family’s rowdy reputation suggests.
Common Problems and Pro Tips
Chemdawg 4 CBD is a predictable, forgiving grow, but it is a balanced 1:1 CBD plant that performs best indoors, so plan for the harvest window and the space.
- Harvest on time for the balance: the value here is the even CBD-to-THC ratio, so follow the 8 to 10 week window and the trichomes rather than letting it over-ripen.
- Grow it indoors for the yield: its indoor yield is steady but light per plant outdoors, so a tent or greenhouse gets far more out of this one.
- Keep air moving: keep flowering humidity down and a fan moving air through the canopy so the buds finish clean as the plant ripens.
Expert tip: it offers Chem flavor in a session you can fully steer. The lemon and citrus over fresh pine with its sweet, woody base sharpens notably through a two to three week cure in jars.
Frequently Asked Questions
Is Chemdawg 4 CBD the same as the Chemdawg 4 strain?
It is the balanced counterpart. Classic Chemdawg 4 is a THC-dominant legend; CBD Chemdog #4 from Blimburn Seeds crosses it with a CBD cultivar to reach 6 to 7% THC and 6 to 7% CBD, keeping the genetics and much of the character at a fraction of the intensity, so you get the flavour without the weight.
Does CBD Chemdog #4 get you high?
Gently. The 6 to 7% THC is noticeable but soft, and the matching CBD share keeps the experience clear: happy, relaxed and uplifted without weight. It suits low-tolerance consumers and anyone who wants Chem flavor in a session they can fully steer, rather than a heavy, intoxicating high.
How long does CBD Chemdog #4 take to flower?
Flowering runs 8 to 10 weeks after switching to 12/12 indoors, standard Chem-family timing. Outdoor plants in a temperate climate finish in October. Keep air moving through the canopy across that window and check trichomes toward the end so you catch the CBD-to-THC balance where you want it.
How much does CBD Chemdog #4 yield?
Indoors, 1.15 to 1.31 oz/ft² (350 to 400 g/m²) of steady production. Outdoors it manages only 3.53 to 5.29 oz (100 to 150 g) per plant, so treat it as the indoor cultivar it clearly wants to be, where you can control the light and climate to make the most of that steady yield.
Is CBD Chemdog #4 a good strain for beginners?
Yes. It grows predictably, trains easily, signals problems early and forgives the fixes, while the gentle chemistry makes the harvest easy to enjoy regardless of tolerance. An indoor space is the one real requirement, since its yield and character both come through best in a controlled grow room.
What does CBD Chemdog #4 taste like?
Lemon and citrus over fresh pine, with a sweet, woody base, the bright side of the Chem genome without the diesel. The profile sharpens notably through a two to three week cure in glass jars, so dry slowly in a cool, dark space and give it that time before you judge the flavour.
