How to Grow Cr +
Cr + is a tall, very high-yielding, mostly indica strain with a Spannabis award behind it, built from the classic Critical Mass x AK47 cross. This 60% indica pairs a bright citrus and sweet flavor with a medium 20-22% THC and a happy, relaxed and talkative effect, finishing in 8 to 10 weeks. It is a productive, forgiving plant, as long as you plan for its size.
This is a feminized photoperiod strain that grows into a large, vigorous plant reaching up to 3 m. Despite being 60% indica it stretches tall, so managing its height is the main part of the grow, but in return it delivers one of the heaviest yields in its class, both indoors and out.

An Award-Winning Strain
Cr + has real pedigree: it took a Spannabis award in 2009, one of Europe’s most respected cannabis events. That recognition is part of why the strain has stayed in demand, and for a grower it is a useful signal that you are working with a proven, well-regarded genetic line rather than an untested novelty.
You can find it alongside our other decorated strains in the award-winning cannabis seeds collection. A strain with an award behind it tends to point to consistent results and a flavor profile that has already satisfied expert judges, which is reassuring when you are committing a full season to a plant this size.
Growing a Tall Hybrid
Although it is 60% indica, Cr + grows into a large, vigorous plant that can reach around 3 m, so managing its height is the single most important part of the grow. It is a feminized photoperiod strain, which means two things: every seed grows into a flowering female, so there is no need to sex the plants, and the plant flowers on light rather than age. Indoors you keep it under long days of around 18 hours while it grows, then switch to a 12/12 light cycle to trigger flowering once it has reached a workable size.
Because it stretches hard after the flip, flip to bloom earlier than you would with a compact indica and leave plenty of headroom. Topping early in veg, low-stress training and a trellis or screen all help tame that tall frame and spread light evenly across the many bud sites, which is how you turn its height into a big, even canopy of heavy colas.
Climate and Where to Grow It
Cr + does well in a warm, temperate climate with good sun and steady airflow. Its quick 8 to 10 week flowering means it finishes around October outdoors, before the wetter, colder weather of late autumn sets in, which helps in regions with a shorter or less predictable season. Given a settled run, it reaches its full, generous potential.
It is a genuinely heavy producer in both settings, which is unusual. Indoors it can reach 650-750 g/m² in a well-managed tent, among the highest yields you will find, while outdoors it gives 550-700 g per plant with room and sun. As a mostly indica that still stretches tall, it needs space either way, so plan for a big plant.
Whichever way you grow it, keep humidity under control through flowering to protect the heavy buds: around 55-60% early on, nearer 40-45% in mid-bloom and lower still toward harvest. Big, dense colas can trap moisture, so steady airflow and sensible humidity are the keys to a clean finish. Aim for daytime temperatures around 68-80°F (20-27°C).
Feeding Schedule (EC Guide)
A big, high-yielding plant like Cr + feeds steadily through its stretch and flowering, but it still pays to build nutrients up gradually and read the leaves rather than overfeed. Taper right off for the final flush so the citrus and sweet flavor comes through clean and the smoke finishes smooth. The ranges below are a starting guide; adjust them to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Light feed while the roots establish |
| Vegetative growth | 0.8-1.2 | Raise nitrogen as the plant stretches |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the heavy colas swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Cr + flowers in 8 to 10 weeks. Expect a strong stretch early in bloom, followed by long, heavy colas forming up the tall frame. As a yield-focused hybrid it rewards good canopy management, since keeping light on all those bud sites is what turns its size into a genuinely big harvest. Outdoors the harvest window lands around October in the northern hemisphere.
Yields are the headline here. Indoors it is exceptional at 650-750 g/m² under good light and a well-managed canopy, while outdoors it gives a strong 550-700 g per plant. Keep the lower growth tidy so energy goes to the main colas, support the heavier branches if needed, and harvest when most trichomes have turned cloudy for the fullest, most balanced expression.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry is especially important on a large harvest like this one, since it stops the denser inner buds staying damp while the outside dries out, protecting both the aroma and the trichomes.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings the citrus and sweet notes forward and smooths out the smoke, and with a yield this size it is well worth the patience to get the whole crop tasting its best.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Cr + carries a good coat of resin, so its trim works well for dry sift, bubble hash or rosin. On a harvest this big that adds up to a meaningful bonus run of citrus-sweet concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Cr + has a clean, approachable profile: a bright citrus note over a sweet, earthy base. It is a moreish, easygoing flavor rather than a sharp or gassy one, and a good cure really brings that citrus-and-sweet character forward in the jar and on the inhale.
Its terpene profile backs that up. Myrcene lays down an earthy, musky base, while limonene brings the bright citrus lift that defines the aroma. Caryophyllene adds a warm, peppery spice and linalool a soft, floral sweetness, with alpha- and beta-pinene giving a fresh, piney edge on top. Together they shape the citrus-sweet, earthy character Cr + is known for.
Effects and Best Use
With its medium 20-22% THC and 60% indica make-up, Cr + delivers a balanced, body-forward experience. It is reported as happy, relaxed and talkative: a good-natured, sociable lift that settles into a comfortable body relaxation. The medium THC keeps it enjoyable and approachable rather than overwhelming.
That balance makes it a versatile strain, relaxing and sociable without being heavy enough to shut you down, so it works well for unwinding with company in the afternoon or evening. The combination of an award-winning pedigree, an exceptional yield and a clean citrus-sweet flavor is exactly why this Critical hybrid stays a favourite.
Common Problems and Pro Tips
The main challenge with Cr + is its height. A plant that can reach 3 m will outgrow a tent fast, so manage the stretch from the start: top it in veg, flip to 12/12 before it gets too large, and use low-stress training or a screen to keep the canopy even. Getting on top of the structure early is the biggest thing that separates a tidy, high-yielding grow from an unmanageable one.
Watch the humidity through flowering, since the big, dense colas can trap moisture in a damp finish. Keep the air moving, bring humidity down as the buds mature, and support the heavier branches so they do not bend or snap under the weight of the flowers. Feed it steadily through the stretch but always read the plant rather than pushing nutrients.
As a pro tip, lean into what this strain does best: it is a yield monster, so give it the space, light and canopy work to earn that big harvest, indoors especially where it can top 700 g/m². Run a clean plain-water flush at the end, then follow the trichomes rather than the calendar and cure for three to four weeks to bring the citrus-sweet flavor forward.
FAQ
Has Cr + won any awards?
Yes. Cr + took a Spannabis award in 2009, one of Europe’s most respected cannabis events. That pedigree is part of its lasting appeal, and for a grower it is a good sign of a stable, well-regarded genetic line that delivers consistent, quality results, which fits its reputation as a reliable, high-yielding hybrid.
How tall does Cr + grow?
It grows very tall for a mostly indica hybrid, reaching up to around 3 m. That means height management is the key part of the grow: top it early, flip to 12/12 before it gets too large, and train the canopy. Give it the headroom and that size turns into one of the biggest yields in its class.
How long does Cr + take to flower?
Cr + flowers in about 8 to 10 weeks. Grown outdoors in the northern hemisphere it is usually ready to harvest around October. Give it a settled, dry finish to the season and harvest when most trichomes have turned cloudy for the best balance of aroma and effect.
How much does Cr + yield?
It is an exceptional producer. Indoors it can reach 650-750 g/m² under good light, among the highest yields available, while outdoors it gives 550-700 g per plant. Results depend on space, light and canopy management, so give it room to stretch and train the canopy to earn the biggest harvest.
How much THC does Cr + have?
It is a medium-THC strain, testing at around 20-22%. That gives it a strong but approachable, body-forward effect rather than an overwhelming one. Combined with its 60% indica genetics, the result is a happy, relaxed and talkative experience that works well socially in the afternoon or evening.
What does Cr + taste like?
It has a clean, bright flavor: a citrus note over a sweet, earthy base. Myrcene drives the earthy base, limonene adds the citrus lift, caryophyllene a peppery spice and linalool a soft floral sweetness, with pinene giving a fresh, piney edge. A good cure brings the citrus-sweet side forward.
