Growing Tips for Our Critical Purple Seeds
Critical Purple seeds are easier to grow than your average cannabis strains. If you are looking for high yields and taller plants then Critical Purple is the strain for you! You can expect plants as tall as four feet so you don’t need a ton of room to grow. The strain requires a warm and sunny environment for optimal harvesting which you can artificially produce in an indoor setup or if you live in a warmer climate you can get from naturally occurring air and sunlight. Beginner growers may find this strain especially easy to cultivate indoors where they have more control over elements such as temperature, light, and humidity. Because the outdoor grow time is shorter if you time it right you can grow this bud in cooler climates as long as you have warmer Summers.
Dial in Your Growing Conditions
- Indoor or Outdoor: Growing Critical Purple plants indoors is easier than outdoors since the lighting, temperature, and humidity can be easily controlled. If the temperature is the desired temperature for this strain you can count on typically higher yields. In an indoor and outdoor setting, you will need to sustain temperatures between 70-80 degrees Fahrenheit for optimum growth. Proper airflow and ventilation are needed to prevent mold from ruining your plants.
- Moisture control: During the vegetative state you are going to want to keep the humidity between 40-50%. Critical Purple benefits from an environment that doesn’t change drastically in temperature and humidity. When grown in soil, be sure to use a rich, well-draining mix with added organic matter.
- Training Techniques: Critical Purple plants need low-stress training and/ or topping to control the height and size of your buds. Consider gently bending and adjusting/tying your stems to promote light exposure and more lateral growth. LST and topping will help create an even canopy which will ensure light gets to all of the buds. Regardless of the grow, higher light penetration is key to making sure each bud is harvested at its peak.

Before you even plant your Critical Purple female cannabis plants, you will first need to germinate these mostly indica seeds. To do so, refer to our free germination guide, knowing that they are backed by our impressive 90% germination guarantee.
Yields, Flowering Time and Harvest
- Flowering Time: This strain has a flowering time of around 10 to 12 weeks when grown indoors and outdoors. Outdoor growers can expect to harvest in late September to mid-October depending on when you planted your seeds in the Spring. This plant requires a steady temperature so you may want to stick to an indoor grow if the temps tend to drop at night where you live.
- Yields: Indoor yields are up to 350 grams per square meter while outdoor grows typically harvest 400 grams per plant. Even though the harvest may seem lighter the ease with which these plants grow makes it worth the time and effort.
Dominant Terpenes in Critical Purple: Skunky and Fruity
Critical Purple’s coffee-esque taste and aroma are created by its dominant terpenes. Everything from the scent to the effects can be attributed to its chemical makeup. The science behind this strain is especially unique and a better understanding of the build of the plant can ensure you get the right flavor notes and scents.
- Beta-Caryophyllene: Spice Up Your Life – Caryophyllene is recognized for its spicy and peppery scent and taste. Known for being super relaxing and relieving stress.
- Beta-Myrcene: Sweet and Herbal – This is a monoterpene hydrocarbon that is found in lemongrass, basil, and hops. This terpene gives Critical Purple a hint of hops and sweet flavor profiles and can also have analgesic and anti-inflammatory effects.
- Alpha-Pinene: Breathe Easy – Helps to enhance focus and memory in Critical Purple plants. This terpene is abundant in conifer trees and is known for its bronchodilator properties.
Dominant Cannabinoids in Critical Purple:
Cannabinoids are the background players in Critical Purple and can be attributed to the many effects the strain has to offer. That feeling of euphoria is in large part due to THC and CBD. The Cannabinoids in Critical Purple are linked to the effect it has to clear the mind and make you sleepy making it the perfect nighttime weed.
- THC: The Main Character – THC is the most dominant cannabinoid on the molecular level of Critical Purple. The crystalline compound tetrahydrocannabinol is the main ingredient of cannabis. Topping out at 18%, the THC in the Indica dominant strain is responsible for the euphoric head and body high and relaxing effect. The THC in Critical Purple will give you a clear head, a relaxed body, and an overall happy feeling.
- CBD: Lower Levels – With around 1% of the chemical compound of Critical Purple being CBD the Cannabidiol in this strain won’t affect your mood or body heavily. This amount of CBD will, however, help with aches and pains and acts as an anti-inflammatory for your tired muscles after a long day.

The buds came out looking like tiny purple-and-green jewels dusted in frost, genuinely one of the more satisfying harvests I’ve pulled off.
stephen_music09 Verified Buyer
This strain’s official tall label felt kind of inaccurate honestly, staying genuinely compact and manageable at around four feet by the time harvest rolled around.
the_real_climbing35 Verified Buyer
Harvest timing felt so intuitive once the trichomes hit that milky balance, and the resulting buds were dense, colorful, and genuinely satisfying to trim.
realFloyd7 Verified Buyer
This plant’s structure genuinely impressed me given how little intervention it needed, staying even and well-formed without any training, matching what I’d read from other growers who skipped it entirely. Flowering time proved genuinely unpredictable beforehand, with published estimates spanning a wide range, and my own timeline landed somewhere reasonable in the middle of all of it. Height stayed modest, around four feet, a pleasant surprise given its official tall classification. I kept temperatures steady in the 70s and avoided any major swings in humidity throughout the cycle. The buds finished dark green against genuinely striking deep purple foliage, the color deepening further after a cooler stretch late in flower. Aroma developed into something fruity and sweet with a distinctive coffee note and light skunky, woody undertones beneath it. First smoke opened with a soft, clear euphoria that eased into a deeply relaxed, calm evening, genuinely one of the gentler highs I’ve experienced this season.
GalloS Verified Buyer
Genuinely appreciated how little intervention this plant needed, structure staying even and solid without any training at all through the entire flowering cycle.
Luca_R Verified Buyer
Flowering duration data for this cultivar showed considerable inconsistency across published sources, ranging from approximately eight to twelve weeks depending on reference material, a notable discrepancy worth flagging for growers planning around a specific timeline. Structural development demonstrated notable self-sufficiency, with even canopy formation achieved without training intervention. Height remained notably compact relative to documented tall classification. Environmental management required temperature and humidity stability throughout the cycle. Bud morphology developed dark green coloration against pronounced purple foliage. Aroma profile consolidated into a fruity, sweet combination with a distinctive coffee-adjacent secondary note, distinguishing this cultivar within a broader collection of comparison strains grown this season.
jules_c Verified Buyer
This plant treated my complete lack of training like it wasn’t even a factor, structure staying even the whole way through regardless.
CoffeeVector Verified Buyer
That coffee note in the smell genuinely surprised me, such a distinctive layer underneath the fruity sweetness that I really wasn’t expecting going in.
matcha_local53 Verified Buyer
Curing brought real depth to the flavor, the fruity sweetness rounding out while that distinctive coffee note became more pronounced over several weeks.
GoldenBison92 Verified Buyer
Trichome coverage was heavy by harvest, giving these dark green, purple-tinged buds a genuinely frosted look that held up beautifully through curing.
