Additionally, information from the breeder or grower can be helpful in getting a rough estimate of when a particular strain should be harvested. Handheld microscopes ranging from 30xx will work and can be purchased at any growing supply store. During their change from clear to opaque to amber, trichomes reach their maximum THC content.
After that, they begin to break down due to exposure to oxygen and UV rays. Strains from regions close to the equator—sativas—need a long, seemingly endless summer to fully ripen, while strains from harsh, cold climates—indicas—tend to finish earlier. That being said, some indicas take a long time to finish and some sativas finish on the early side. As cannabis buds pack on weight and the season changes from summer to fall, there will be fluctuations in the weather.
Depending on your climate, there might be cold snaps or rainstorms. But a hard freeze, any temps lower or for longer, can spell disaster. Frost can cause ice crystals to form in plant tissue, damaging their cells.
Leaves will appear wilted before turning dark and crispy. The deeper the frost, the more of the plant that will get damaged. Note that potted plants experience more severe temperature fluctuations than plants in the ground, making them more susceptible to frost damage. If the rain will be there to stay, mold awaits—cut your losses and harvest before things get soggy. Covering your plants will help, but there will still be moisture in the air. You can cover plants with a few tall stakes and a tarp, just be sure to remove the cover when the cold or rain passes to let plants warm up and get the sun and air they need.
When growing weed indoors, you can harvest as much or as little as you want. The sky—rather, your grow room—is the limit. Ideally, half of the trichomes should appear milky white and the others should be a vivid amber. Clear trichomes, on the other hand, indicate that it's a good idea to wait a little longer before harvest. Of all the signs to look for, trichome color is the most reliable. This color change might be hard to see with the naked eye, so make sure you have a magnifying glass handy.
Leaf color: Another reliable indicator of when a marijuana plant is ready to harvest is the changing shades of the fan leaves.
During the flowering stages, nitrogen gives the leaves their green color. When it's time to harvest, fan leaves will turn yellow and start to fall off as nitrogen decreases. Curling leaves: As the fan leaves turn from green to yellow, they may also curl and dry. The lack of moisture is a natural occurrence as cannabis plants take in less water when harvest time draws near. Brown pistils: For photoperiod cannabis plants , the pistils will turn brown at maturity.
The optimal time to harvest is when about half the pistils are shaded brown. Similar to checking trichome colors, you'll want to have your magnifying glass handy for this step. Bud shape: Though not as surefire a way to know when it's time to harvest as the trichome test, the shape of the buds can still offer a few hints about the plant's maturity.
If you believe your plants have a calcium deficiency, invest in a Cal-Mag calcium and magnesium supplement. As magnesium is a mobile nutrient, your plants can transport it from old leaves to new ones. The problem with this deficiency is that it can quickly cause your plants to lose many lower leaves. Your plants may have a magnesium deficiency if the bottom leaves on the plant have yellow or bright green edges that feel crisp to the touch.
The generic temperature range for OG Kush is between and degrees Fahrenheit. It handles lower night-time temperatures better than most strains, and you must drop the humidity during flowering. During the vegetative stage , keep the temperature close to 80 degrees. Once your OG Kush reaches the flowering stage, drop it to around 70 degrees.
Ensure there is no more than a degree drop between day and night temperatures throughout the growth cycle.
If your grow room is too cold for a prolonged period, you will shock your plants, slow down growth, and possibly kill the entire crop! Colder temperatures also increase the risk of mold. It is potentially harmful to allow your grow room temperature to exceed 80 degrees.
This slows down bud growth during the flowering stage and reduces the aroma and potency of the buds. Excess heat also increases the risk of attracting pests such as spider mites. Additionally, the leaves can wilt due to root oxygen deprivation.
The game changes when you add carbon dioxide enrichment to the equation. Marijuana plants breathe CO2 rather than oxygen because it is a vital part of the photosynthesis process. CO2 enrichment also ensures your plants are more resistant to heat and light stress. With CO2 enrichment, your crop grows in an environment where the air contains ppm of CO2. For it to work, you have to seal up the grow room and release more carbon dioxide into the air.
A CO2 generator is the most obvious choice, but you can also purchase compressed CO2. OG Kush is susceptible to these twin problems. Bud rot is a form of mold that develops on the stem inside of the bud. It spreads outwards and is notoriously tough to catch early on. If you catch the rot too late buds look grey and squishy , you may have to discard the entire plant. Bud rot loves an excessively humid environment and also thrives in poorly ventilated rooms. Purchase high-quality fans to promote good airflow and consider pruning your OG Kush plants if they become too thick.
If you find bud rot on a plant, remove the affected area and place the rest of the plant in a separate room.
