It is a natural, odourless, aerobic process, much different from traditional composting. The deficient plants can be directly treated with a foliar spray without jeopardizing the other plants feeding schedule.Vermicasting, also called vermicomposting, is the processing of organic wastes through earthworms (Figure 1). This is especially useful if there are multiple plants in your system and only a few are showing signs of a deficiency. This way you don’t have to change your standard feeding regime. For example, if your plant starts to show signs of calcium and magnesium deficiency while you are running a nutrient-rich feeding regime, you could look to use a cal-mag foliar spray at lights off every five days to rectify the issue. Do Use Foliar Absorption to Your Advantageįoliar sprays are a great way to tackle nutrient deficiencies. There are also spray bottles that can be used upside down, which is great for getting into tight spaces and spraying the bottom of leaves. Again, the finer the mist, the better it will be for the plant to absorb. It may take you a few attempts to get it right.Ī great tip is to use a foliar sprayer that can be adjusted to expel a fine mist. If the leaves are dripping wet, you have used too much. Remember, less is always more as your plants need to absorb all this liquid before the lights come back on. This would have the same negative effects on the plant as if the foliar spray was applied when the lights were on as discussed previously.ĭo Use Proper Technique When Foliar SprayingĬover the plant’s leaves and stem with a light spray. If you were to spray your plants too close to lights on, the plant could still be wet when the lights come on. Spraying your plant at this point also means that it has the maximum amount of time to absorb the nutrients. It’s during this time-right after the lights turn off and before the leaves relax-that the stem and leaves are in their most effective absorption period. When a plant enters a dark period, its leaves take around 15 minutes to relax. The best time to use a foliar spray is at lights out.

When using a foliar spray, make sure you read the instructions twice and stick to the dilution rates on the label. Environment is such an important factor in modern hydroponics that I personally wouldn’t do anything to mess it up.ĭon’t Use an Overly Concentrated Foliar Spray During the flowering stage, your humidity is already high. While this is great while your plant is in its vegetative stage, it can be a problem when your plant is in flower. Don’t Use a Foliar Spray if it Will be Detrimental to Your Growing Environmentįoliar feeding increases the humidity within the growing environment. However, it will not be able to breathe or self-regulate if the leaf is covered in a liquid that is causing its surface to burn. Usually, when a plant gets too hot, its stomata open to release heat, gas, and water to cool down. The first thing that’s going to happen is that the liquid will act as a lens, amplifying the heat from the lights and burning the leaf. The plant cannot absorb the freshly sprayed liquid fast enough. If you are growing in an environment with a powerful artificial light source, the last thing you would want to do is to cover your plant in a liquid while the light is on.
