Your little canna-babies might be a work of love, but it is possible to love too much. Or not enough. Cannabis plants are just like other plants; they need to be properly tended and should be given a good and “steady” home. To thrive, cannabis needs a schedule to be fed and watered just the right amount. They need to have a strict curfew on their “bedtime" - consistent light allowance is critical. Cannabis plants are also very heat and light sensitive.

If your ganja grow sounds a bit like raising children, that is because it kind of is. And while this is a hardy plant, care and love always produces a better result.

The benefits of a well-tended grow? Happy plants and bountiful yields. And the penalty if you do not treat your plants just right? Smaller yields, if not popcorn buds – or even no buds at all. Not being treated right causes stress to cannabis plants. And stress does not bring out the best in your cannabis crop.

Here are some common types of stress and how they can be avoided.

Watering Issue Cannabis Plant

WATER STRESS

Every plant needs water. Cannabis is no exception. Water helps plants create their own “food” in the form of glucose. As such it is a key component of photosynthesis. The water turns into CO2 as it evaporates. Internally, water pressure also helps leaves keep their internal structure. Hydrated leaves do not wilt. Too much water, however, is just as stressful as not enough water - preventing nutrient uptake and resulting stunted growth. Keeping your plants in a warm, moist environment is key to ensuring happy, unstressed grows.

LIGHTING

When growing outdoors, lighting is not an issue, as things happen naturally. But move your plants indoors and you become the “sun” and the “moon.” It is critical to keep strict light schedules for your plants. They need both light and dark and on a regular schedule. During the vegetative stage, your plants will need 18 hours of light. During the flowering stage, plants need much less light. About 12 hours. Making the switch at the right time will definitely affect your yield.

Beyond light periods, it is also critical to design your interior lighting to give your plants what they need. If lights are placed too far or too close to the plant, it might not get enough light - too close also runs the risk of causing heat stress. If the canopy is not properly architected, lower buds will receive less light than they should to grow properly. Light access is also one reason why many growers implement ScrOG or other grow structure early. Training plants to grow in a certain way is also one way to ensure an even spread of light reaches every flower.

Indoor Growing Lightning And Temperature

TEMPERATURE

Plants which are exposed to cold get stressed. This means making sure that nighttime temperatures, where-ever you grow, do not sink too low. While plants exposed to cold can sometimes display unique characteristics – like turning purple, this is not good for them. Most outdoor cannabis must be harvested by October for that reason.

Likewise, if conditions get too hot, cannabis will suffer heat stress, which can permanently damage leaves, thus affecting overall growth performance.

As a general rule of thumb, 20-28°C is seen as the safe/optimal range for cannabis to grow. It can vary depending on the strain, but this is a good general target to aim for. If outdoors, temps can get colder at night, just try to make sure you never have plants growing when the weather begins to get frosty.

FOOD STRESS

Feeding your plants the right food and the right amount of it, is crucial to maintaining stress-free grows. Commercial plant food for cannabis plants is easy to find. However, the temptation to overfeed can also be high for new growers. Don’t think that “more” is always better. On the flip side, a regular feeding schedule is critical for plant health. Overfeeding can cause build up in the soil, which opens up a whole can of worms. Be sure to check out our guide to stress-free feeding.

PH Of Soil In Cannabis Cultivation

THE RIGHT PH

Cannabis plants require a soil pH of between 6 and 6.5. The pH level of soil is a measure of how acidic or alkaline it is. Higher numbers – above 7, show that the soil is more alkaline, while numbers below 7 are more acidic. Cannabis is just about in the middle. You must keep the soil in this general range otherwise the plant will experience stress. You should also make sure the water you feed your plants falls in this PH range. Note: for hydroponics, the ideal pH range is a little lower - between 5.5-6.5.

If cannabis falls outside of the pH range, it can cause nutrient lockout, which in turn, stresses the cannabis and causes problems.

TISSUE DAMAGE

Just like humans, plants feel stressed when they get bounced around. Or attacked by pests. Or dropped. Try to move your plants as little as possible and keep them in an area where they safe from pests. Planting companion plants, even indoors, can help create a natural shield around your plant. When pruning the plant, also try not to shock it by taking too much. While pruning is also important for overall plant health, it can be a source of stress.

So there you have it! You should now be aware of the main types of stress you cannabis can face. It is in every growers interest to try and prevent over stressing plants, so be sure to read our more indepth articles on each subject linked in the relevant paragraphs above.
