Support: Some plant need trellising- knowing the average and max strain height ahead of time will help determine if your plant will need support with trellises and/or stakes.

The benefit of growing from a single phenotype is that all clones from that strain will grow the same way and produce the same characteristics with only very slight variation. Also, you will have knowledge about these strains if you choose to grow them again. Our strain catalog includes grow-tips generated from farmers who have grown our strains to offer first-hand knowledge on what to expect from our strain phenotypes.


Processing: How will it be processed once finished? Some strains need more attention when it comes to trimming and others can just be put through a trim machine like the tumbler.

If there is a spot on your property that stays shady for the majority of the day, don’t put your plant(s) there.

There are many soil amenities that can add benefits to your soil in pots or in the ground. Examples are coco coir, worm castings, seabird guano (poop), so you’ll want to consult your local “grow store” for suggestions on soil mixtures.

Drying and curing inevitably shape flavor and effect, for better or worse. Preserving and developing the cannabinoid and terpene profile is a delicate process. Temperature and humidity should be controlled and adjusted according to flowers’ density and terpene content. Flowers that are dried and cured correctly offer a smoother, more nuanced smoking experience. “The high of cured weed is always deeper and more introspective, often becoming a meditation and inner-vision tool,” says Franco. “The flower becomes much more complex and refined, gaining in depth as well as in variation of bouquet.”

Once plants have been harvested, they must be dried to reduce water content and remove chlorophyll. Plants should be hung in a climate-controlled room for 10 days to two weeks, although some claim that as few as five or six days can be sufficient and others insist that two weeks is the minimum. According to Franco, of Green House Seed Co., “The difference between drying 10 days and 14 days is not very evident to the novice, but creates a world of difference to the connoisseur.” Flowers that are dried too rapidly will have a harsh or bitter flavor, and flowers that are too moist will not burn.

Boutique farms are more inclined to dedicate extra time to produce a premium product. Nikki Lastreto of Swami Select says, “We like our flowers best around April. Some strains take longer to ripen — full Kush strains aren’t quite ready until July.”

The Impact of Harvesting, Drying, and Curing Decisions on Seasonal Cannabis Availability

When flowers ripen in the fall, farmers must choose the most opportune moment to harvest. Flowers that are harvested early induce a lighter, more cerebral high, and flowers that are harvested late have a more narcotic body effect. A later harvest also leads to increased risks from mold, mildew, pests, and damage from frost or storms.

Cultivation techniques, strategies, and preferences affect the growing season as well, and farmers make calculated decisions based on their experiences and objectives. Many believe it is better to plant when the moon is waxing and harvest when the moon is waning. Guerilla growers sometimes plant later in the season, a strategic decision resulting in smaller plants that are easier to conceal from law enforcement. Regulations such as plant count limits incentivize some legally permitted cultivators to plant early in order to grow larger plants.

Connoisseur-quality cannabis should be cured after drying, but commercial growers rarely take the time to do so. “In a perfect world, there would be about six to eight weeks between cutting the flowers, hanging to dry, trimming, and then stabilization,” says Kevin Jodrey, the cultivation director at Wonderland Nursery in Humboldt County. “The reality is that the grower prays for a quick drop as soon as it is dried and trimmed, which could be as short as 10 days from chop to sale.”

In the northern hemisphere, seeds are planted as early as March or as late as May, and flowers are harvested from September through November. Seasons are reversed in the southern hemisphere, so planting takes place from September to November and harvest time is March to May. In the tropics, near the Equator, it is actually possible to harvest outdoor cannabis throughout the year.
