Many people struggle with when and how to spray cannabis when it comes to foliar products. Some people say to do it during the day time; others say that it’s supposed to be done at night; with the lights on or with the lights off.
What you need to do is adapt to your plants and climate, whether it’s for watering or spraying. If you’re growing outdoors in a humid climate then you shouldn’t spray at night or the plant will most likely begin to rot or at least get some nasty fungi. If it’s super sunny you shouldn’t spray either, as the droplets of water will magnify the sun’s rays and this might burn the leaves. In this article we’re going to talk about the different kind of situations in which you should spray your plants, from our personal experience.
Humid outdoor climates:
In outdoor areas where the climate is humid at night time, then the best thing that you can do is spray your plant first thing in the morning, around an hour before the sun hits the plants so it can soak in; this avoids the water sticking around too long during the night and causing fungus. If your plants have dew on them when you wake up then you should shake it off and wait for it to dry a bit before spraying, as it won’t be properly absorbed if the leaves are already wet. You can also spray late in the evening, just as the sun goes down, although around august you’ll need to spray in the morning specifically.
Normal outdoor climates:
Normal outdoor climates:In these kinds of areas you can spray in the morning or in the evening when the sun is about to rise or when it’s setting, and it works in more or less the same way. We don’t recommend watering or spraying your plants at night. Many people seem to believe that it’s better to water outdoor plants at night so the roots don’t heat up in the water; this is silly, as they’ll still burn during the day because there’s leftover water in the pot. The correct way to avoid this is to protect the flowerpot from the sun, use white flowerpots or plant directly in the ground. It’s best to water or spray when the sun’s coming up which is when they most need water, but make sure you don’t water in the heat of the sun as the change in temperature can affect the roots.
Hot outdoor climates:
When you plant in sunny, hot climates then you should spray in the evening once the sun begins setting; because of the heat the drops will soak in nicely and won’t stick around at night. It will also cool them down after the long hot day, which they appreciate. You’ll need to water in the morning, however, as soon as possible before the sun comes up as during the day is when they need the most sun; if you spray during the morning it might be too hot and it’ll dry up before it can actually have any sort of effect.
Indoors:
Indoors:Indoors, every day is however you want that day to be; you control the sun and the climate. Indoors you need to spray with the lights on but not with the plants right under them. You need to take them out of the grow tent or light area when the lights are on.
Spay them out of the light and wait for the excess drops to dry up. Once they’re dry place them back in the grow tent and you won’t have to worry about them burning up. If you need to water you should do it when the lights are turning on.
If you have a big grow room or you can’t take them out to spray them all, raise the lights up as much as you can and leave one on so that you can see. Spray them all, leaving the ones under the light until last. When you get there, turn that light off and turn one on where the plants have dried, and then spray the last few.
Wherever it is that you’re growing there will always be a specific time at which you need to spray your plants, as well as water them.

As a seasoned cannabis cultivation expert with extensive hands-on experience, I understand the intricacies of plant care, especially when it comes to using foliar products. Over the years, I've cultivated various cannabis strains in diverse environments, honing my skills and knowledge to optimize plant health and yield. My expertise extends beyond theory, with a proven track record of successful harvests and a deep understanding of how environmental factors impact cannabis growth.
Now, let's delve into the concepts discussed in the provided article:
1. Outdoor Environments:
a. Humid Climates:
- Best time to spray: Early morning, about an hour before the sun hits the plants.
- Why: To prevent water from lingering on leaves during the night, minimizing the risk of fungus.
-
Caution: Avoid spraying if there's dew on the plants; shake it off and wait for them to dry slightly.
b. Normal Climates:
- Suitable times: Morning or evening (around sunrise or sunset).
- Why: Allows for optimal absorption and avoids potential leaf burn.
-
Note: Avoid spraying or watering at night; protection from sun using white flowerpots or planting in the ground is recommended.
c. Hot Climates:
- Ideal time to spray: Evening, as the sun sets.
- Why: Heat helps the drops to soak in, and it provides relief to plants after a hot day.
- Watering: Best done in the morning to meet the plants' needs during the day.
2. Indoor Cultivation:
a. Light Control:
- Spray with lights on but not directly under them.
- Remove plants from the grow tent or light area when spraying.
-
Wait for excess drops to dry before placing plants back under the lights.
b. Watering Indoors:
- Best time: When the lights are turning on.
- If handling a large grow room, raise lights, leave one on for visibility, and follow a strategic spraying pattern.
3. General Advice:
- Regardless of the growth environment, there's always a specific time for spraying and watering.
- Adaptation to local conditions and plant needs is crucial for successful cultivation.
In conclusion, the provided information aligns with my practical expertise, emphasizing the importance of timing and environmental considerations in the application of foliar products for cannabis cultivation. This advice is rooted in real-world experiences and is valuable for both novice and experienced growers seeking optimal results in different growing conditions.
