Open the jars every so often to check on the state of the buds. If they're getting too dry, you need more humidity; if they're beginning to stick together or smell musty, you need less. The ideal range is 60-65%. Consider investing in a hydrometer to help you manage the humidity with precision.
This plant produces a pungent, skunk-like odor that is pleasing to some but repulsive to others. Now, researchers reporting in ACS Omega have discovered a new family of prenylated volatile sulfur compounds (VSCs) that give cannabis its characteristic skunky aroma.
Cannabis plants need light to create energy. However, depriving your plants of light close to harvest serves as a last-minute method to boost terpene levels. Shut off your lights 24–48 hours before harvest to add a flavourful kick to your buds.
Before harvesting, essential oils and food-grade extracts might penetrate your buds via your plant's roots. To prevent an unpleasant taste in your buds, use edible essential oils. Combine 15 mL of extracts or essential oils in 20 liters of water and pour the solution onto the soil for up to 5 hours before harvesting.
Quality cannabis has a healthy green color and can have touches of red, orange, and purple all depending on the strain. Bad buds look old — it's a muted green, brown, tan or even yellow, and if you spot anything that looks like mold, don't buy it.
Lack of light is perhaps the most common reason that cannabis produces fluffy, light buds. You may have noticed the lower, puny 'popcorn' bud sites that form below the main canopy. Often these buds are discarded by growers allowing the plant to focus biochemical energy on the main blooms.
Bud structure
High quality, developed flower from a healthy plant has a sturdy, fully three-dimensional structure. The buds should be solid, with no gaps that you can look through. It's properly cured: not too soft, but not so dry that it grinds down to dust. Flower with poor structure will appear flimsy and flat.
The last three weeks is when your buds can actually gain the most weight – that is if you feed them Overdrive®. After your peak bloom phase, your plants enter their late bloom phase (the precise timing and length of which depends on the strain of cannabis you're growing).
A bud hardener is an additive you can use at the end of the flower cycle to tighten up your flowers and pack on weight. They are typically used in the final 3 weeks or so of the grow cycle and contain a mix of macronutrients, micronutrients, minerals, essential oils, etc.
Bud rot has a very distinct smell and once you know it, you can't forget it. Have you ever left your wet clothes in a pile for too long, only to remember they exist when your house stinks? Moldy weed can be compared to that smell. It may also be compared to rotting fruit, sweat, wet hay, and urine.
So how do you know when it's time to harvest? The telltale sign of harvest-ready weed is when the hairs of the plant, or pistils, have fully darkened and curled in. If your buds are looking thick and dense, but there are still some straight white pistils, it's not time yet.
In most circumstances, overripe buds are still usable. But less potency and poor smoke quality, but they'll still get you high. The only way to tell if your bud is ready to smoke is by looking at the color of the leaves: if they're brownish, your bud is overripe.
And according to the results, vanilla is the most pleasing smell around, followed by ethyl butyrate, which smells like peaches.
Over time, many of the cannabinoids and terpenes found in cannabis slowly break down and lose potency. As the terpenes break down, your bud loses flavor and scent. As a result, old bud is relatively tasteless and lacks that distinctive, sharp odor that fresh weed is supposed to have.
While the process to harvest your plants isn't all that complicated, knowing the perfect time to do so is less clear. And the timing is critical. If you wait too long, your buds will be overripe and possibly ruined. If you harvest too early, the buds may not have finished growing (and developing their potency).
If you're growing in soil, begin flushing between one and two weeks before harvest. If you're growing in coco, flush your plants for up to one week prior to harvest. If you're growing in hydro, your plants only need to be flushed for one to two days.
Timing the harvest is Paramount to the final quality. Harvest your precious buds in the dark, just before the lights normally come on. If possible, do not allow the plants to see direct light as long as their roots are attached. Direct light on a plant will draw up stored starches and sugars from the root system.
Cut the branches with buds into manageable sizes.
Similarly to wet trimming, you'll start by using your large shears to cut through the thicker branches. It's pretty simple — just make sure the branches attached to the buds aren't too short or too long for you to easily handle them.
It can be dust, dirt, bugs, all of which will affect the final flavor and quality of your buds. To get a good clean product, you can wash your buds after harvest, to remove these contaminants from your flowers. It is easy to do, it doesn't wash off any of the oils, cannabinoids or terpenes.
Treatment. After bud rot has set in, there's not much you can do to reverse the spread of the fungus. If you notice a section of your garden has bud rot, there's a strong possibility that the rest of your garden is infected too. To prevent the fungus from spreading, remove all infected plants.
An ideal time to dry cannabis is around 5-7 days. However, the time it takes to reach the ideal dryness (explained below) will vary depending on your climate and drying location. Also, the condition of your plant will play a role, such as how fat the buds are, how many fan leaves are still attached, and so on.
Cannabis plants are happiest when they get between 10–12 hours of direct sunlight per day. As you'll likely have witnessed with your own eyes, weed plants grow really vigorously, and hence need a ton of solar energy to fuel their growth.
