You’re going to do everything you normally do when it comes to watering, except without any additional nutrients or supplements. Don’t give more water at a time than normal, because this increases the chances of your plants getting overwatered and showing deficiencies/symptoms caused by that problem.
You’ve done everything you could to ensure the smoothest buds, so now it’s time to enjoy the fruits of your labor!

During the flush before harvest, your plant can lose its green color very quickly. Although it’s normal to see some amount of yellowing before harvest, it’s important to harvest before the sugar leaves on the buds themselves have turned yellow. Although this doesn’t affect the quality of the buds, it does affect the appearance and buds aren’t as pretty. Additionally, once all the leaves have turned yellow your plant won’t really mature a whole lot more, and buds can start to deteriorate quickly.
Flushing is Simple & Free!
The idea behind flushing is to let your cannabis plants “use up” any extra nutrients contained in the plant and buds. This way there is a much lower level of nutrients left over after harvest, and it’s those extra nutrients that can change the smell, taste or (most often) “smoothness” of your buds in a negative way.
Plus it makes sense that growers who have only been providing water to their plants the whole grow don’t have any need to flush – what would they do different anyway?
If you let the flush go this long, where buds are getting crispy and brown without any sign of green, it means the actual potency of your bud is starting to degrade. This bud needs to be harvested immediately so you don’t lose further potency!
Why avoid flushing buds early? You can read the full explanation here, but basically buds harvested on the early side tend to be more “racing” or possibly have a paranoia-inducing effect, while waiting longer to harvest increases THC levels and intensifies the psychoactive properties of your buds. Waiting even longer makes buds that are still potent and psychoactive, but the extra time in the flowering stage also starts to add a more relaxed,”couchlock” effect as some of the THC degrades to CBN.
Flushing before harvest can increase the quality of your buds, but it can also hurt your yields and even REDUCE the quality of your buds if you do it too early! Learn how to flush properly!
Plants could harbor powdery mildew or another disease within their tissue. This disease is impossible to detect without laboratory analysis. Such diseases weaken plants and could also play a part in the deterioration of fragrance.
The aroma, taste and ultimately effects of smoked cannabis depend upon the mix of terpenes and cannabinoids. Often cannabinoids and terpenes volatize and are destroyed during flowering harvest and storage as a result of high temperatures and maltreatment. The absence of these compounds diminishes bouquet and taste. It can also affect the overall effect of the cannabis.
“Terpenes, or terpenoids, are the compounds in cannabis that give the plant its unique fragrance. THC and the other cannabinoids have no odor, so marijuana’s compelling fragrance depends on which terpenes predominate. It’s the combination of terpenoids and THC that endows each strain with a specific psychoactive flavor.” Martin Lee
Avoid the taste of chemical and organic fertilizers in harvested buds by leaching with plain water or a clearing solution to remove any residuals and chemicals that have built up in soil or plant foliage. Five to six days before harvesting, leach the growing medium with clean tap water or reverse osmosis water. Use a clearing solution such as Final Flush® to remove any built-up nutrients in soil.
2. Leaves are brittle at harvest
Terpenes and cannabinoids evaporate into the air in a wide range of temperatures, 119-435º C. As temperatures climb, more and more terpenes evaporate into the air. Terpenes can also be destroyed with high temperatures, humid weather, wind, rain, fondling and rough handling. The terpinoids may also not have a chance to develop properly on plants that grow under stressful conditions including climate, care and disease and pest attacks.
Plenty of air circulation and ventilation is necessary to promote manicured flower buds to dry. The buds in these net trays are turned once or twice a day by hand so they dry evenly.
When poorly dried and it stays too wet, as if in a compost pile, cannabis starts anaerobic decomposition. This process causes cannabis to smell like wet hay and extreme cases have an ammonia-like odor.
Cannabis plants lose their fragrance for a combination of reasons, all of which involve destruction of terpenes or the creation of a poor environment for terpenes to develop. During flowering plants that are subjected to heavy weather including wind, rain and hot sunlight or artificial light, are often less fragrant. Outdoor plants also accumulate surface dust, bacteria and other bad stuff. When allowed to remain on the plant these pollutants can smell and possibly speed cannabinoid and terpene degradation. Often indoor environments are more polluted than the great outdoors. Such pollutants could also play a role in diminishing fragrance.
Before Harvest Watering is important when plants are flowering. Continue regular irrigation as needed. Make sure to check the soil moisture daily to avoid overwatering. Always irrigate in
