It is advisable to take proper precautions to protect your plants from excessive wind or airflow damage. Moving air can provide numerous benefits for cannabis plants, including making the stems stronger. However, too much of it can cause significant structural damage, affecting health and yield in kind. In strong enough winds, plants can be toppled over or completely uprooted.
Stems and branches can also be broken or bent from the utilisation of growing techniques like low-stress and high-stress training methods. Techniques that bend or otherwise stress branches inherently have the potential to lead to stem complications. Even if branches don’t split or break completely, the damage caused by bending them too much can harm plant vigour and production.
Stems can be damaged by something as simple as moving plants carelessly. This can especially be a problem with plants that are more rigid and upright. Moreover, damage from wind or excess airflow can similarly damage branches and stems.
HOW TO FIX BENT STEMS
Tip: Be sure to wrap the tape around the branch as tightly as possible. Packing everything together will greatly assist the healing process. When removing the tape, take care so as to not damage the stem again. Sometimes the stem may still be fragile or may not have fully healed. In these situations, it is easy to retear the stem unintentionally.
This is the most common type of stem damage that occurs. When branches are bent or stressed too much by training techniques, permanent damage can occur. Bent or folded stems are unable to support themselves. Bends or folds can make it more difficult for branches to receive water and nutrients from the plant. These stems will continue to grow, but at a slower pace than the rest of the plant. This is not just because they are bent, but because their bending makes them hang lower, potentially blocking their exposure to light.
Similarly to fixing broken or detached stems, be very careful when removing the tape. Bent stems can be easily damaged again if not careful.
Bent stems can be fixed with support structures. Follow these steps to fix a bent stem:
To determine the sex of your cannabis plants, you will have to wait until the pre-flowering stage when plants begin to put their energy into reproduction. Female cannabis plants show their gender signs later than males. At the location where they will soon grow their buds (the nodes between the stalk and the stem), females will show wispy white hairs.
Pollination requires the presence of males or intersex (hermaphrodite) plants, which are females that will also produce pollen. The first thing you want to do to keep the risk of pollination low is to remove as many males or “hermies” as as you can. Especially during the first three weeks of flowering, it’s important to frequently check for possible male specimens in your garden.
Another indication of pollination can be the colour of her pistil hairs. When a female has been pollinated, the previously white hairs will soon shrivel and become darker.
WHAT TO DO WHEN YOUR FEMALES GET POLLINATED?
Spotting male cannabis plants and pollinated females early can save you from investing further time and effort into an entire growing season that will be for naught. Most of the time, the best course of action is to get rid of the males along with your pollinated ladies and just start a new grow.
Pollination of your female cannabis plants will make them produce seeds and spend less energy on producing quality buds. But when you recognise the signs of pollination early, you can avoid putting time and resources into a poor harvest.
A good test to see whether the bracts have swollen is to take a pair of tweezers, grab one bract, and open it up. If there is a seed inside, you have a pollinated plant.
