This is what the buds of a “true” landrace Sativa looks like – basically all foxtails! Most available “Sativa” strains are actually hybrids with at least a little Indica genes mixed in to help increase bud density and improve overall structure. Example of untrimmed, dried buds of a Blue Dream plant, a very popular Sativa-leaning cannabis hybrid that’s become well known for being easy to grow. Often have long, skinny leaves Generally stretchy appearance with lots of side branching and plenty of space between sets of leaves (as opposed to the short, squat Christmas tree shape of an Indica plant). Tend to grow tall and fast throughout their life, and may double or even triple in height after entering the flowering stage!
Buds often have “foxtails” and may be loose or airy compared to Indica buds, which tend to be solid and dense. However, a well-bred Sativa strain can still often out-produce an Indica in the same conditions because everything about the plant grows so big and so fast. Long, thin “fingers” on Sativa leaves, compared to Indica leaves which tend to be round and fat. Sativa plants tend to grow tall, with lots of stem between leaves and extensive side branching. Sativa buds tend to give a more cerebral “in-your-head” effect than the more “body-based” Indica effects. Sativa buds may feel more energizing, so some people prefer Sativa strains for daytime use or in social settings. A Sativa-based strain with a little bit of Indica genes.
The buds from another “pure” Sativa strain – Although the buds are airy and a little strange looking, some of these old Sativa strains produce unique mental effects that you just don’t find anywhere else. Only a few decades ago in the USA, this type of cannabis was common! Now you’ll almost never see buds like this unless you grow them yourself. Sativa plants generally respond well to high levels of light and don’t mind a little heat, but can easily get stressed by cold temperatures Can be nutrient-sensitive, especially in dry heat, low light levels or if a plant does not have many leaves. Not uncommon to see nutrient burn or Nitrogen toxicity at standard-strength nutrient levels. It’s a good idea to give lower levels of Nitrogen if you see an N toxicity, this will help encourage as much bud growth as possible. You don’t want to give zero Nitrogen, but be on the lookout for dark green leaves and curled tips! Example of buds on a Sativa plant that is suffering from a Nitrogen Toxicity (too much Nitrogen) in the flowering stage. Nitrogen “tells” the plant to focus on vegetative growth, and the plant keeps putting out more and more sugar leaves if given too much N in the flowering stage. These leaves will turn dark, bend, and eventually turn yellow again as the toxicity goes on. Sativa plants respond well to LST (low stress training), and are difficult to stress once they’re growing fast. If you’re naturally seeing a significant amount of stem between sets of leaves (as is common with many Sativa strains), defoliation can sometimes do more harm than good. With a stretchy plant, the buds and inside of the plant are often already as exposed as they need to be for optimum results. Defoliation is most effective at increasing yields of bushy plants where buds get hidden by leaves, which is much less common with Sativa strains than Indica strains! You might not want to choose Sativa-based strains if you’re using a small grow space like this! Example of a Sativa plant that’s 2 feet tall at only 5 weeks old, and already had to be topped to keep it short! This is a very typical vegetative growth structure for a Sativa plant. Some Sativa strains may need 3 months in the flowering stage to be ready to harvest on the standard 12/12 flowering light schedule. In order to “hurry them along,” they may need longer than average nights until harvest, for example, an 11/13, 10/14 or even 8/16 light schedule! Can be more common to get hermies, especially under stress or close to harvest if buds are not pollinated. If buds appear mostly done and suddenly throw out a bunch of bananas (a type of hermie), it could mean it’s time to harvest. Sativa plant in the flowering stage – may grow with lots of stem between sets of leaves. If you initiate the flowering stage when the plant is still very small, you may end up with just one long bud like this. Example of the power of Sativa cannabis plants when they’re trained to grow flat and wide during the vegetative stage – look at all those huge Sativa colas that are all the same distance from the grow light! These plants still have several weeks of fattening left to go before harvest! Sativa buds may be airier than Indica-leaning buds on average, but they make up for it with good yields, fast growth and soaring, memorable bud effects!
This Sativa-leaning Chem Dawg strain grows mind-altering buds that feel “up” but still relaxing! Some Sativa strains have trichomes that may never turn amber even after months of flowering.
If your plant has fully white trichomes, it’s possible it may be time to harvest even if no ambers are appearing. Harvest when trichomes are mostly cloudy with a few clears left for the most psychedelic effect Look below for two examples of trichomes from Sativa plants that are ready to harvest. Trichomes should be mostly milky white with just a few clears for maximum potency! These buds are ready to be harvested, but it’s still on the early side because there are quite a few clear trichomes left. These buds are smack in the middle of the harvest window.
