Foliar feeding can be incredibly beneficial for your marijuana plants. Although this tends to go against popular perception, marijuana plants require regular spraying and/or misting. Plants can and will absorb nutrients from their leaves with a nutrient solution mixture.
Foliar feeding provides a rapid boost to your marijuana plants, ultimately producing larger, better, and more bud-filled harvests. That being said, foliar spraying cannot replace a standard root feeding regimen. Instead, it provides a quick way to get supplementary nutrients to your plants.

What Does It Mean To Foliar Feed Cannabis
Foliar feeding essentially means that you spray fertilizer straight onto the leaves. It provides nutrients via foliage rather than roots. The process has been the subject of a number of scientific and anecdotal studies, prompting many growers to use it in their growing programs. A regular regimen of spraying feeds the plant via its stomata—microscopic openings situated in the middle of two guard cells—with direct nutrients. Regular spraying also provides clean and open stomata for your plant. Alterations in water content around the guard and other secondary cells force the stomata to open and shut as a basic response to water status changes.

Marijuana plants continue with the process of photosynthesis by mixing together a number of different ingredients in their leaves. Materials can be gaseous (e.g. carbon dioxide), liquid (e.g. water), and energy (light). Simply looking at the plant’s leaves gives you an insight into how they can create food. Stomata are vital for providing access to and from the plant for gaseous materials. Stomata are like tiny pores in the skin of your plant. If more carbon dioxide is necessary for photosynthesis, the stomata will open. If the leaves overheat and need to let water escape during transpiration, the stomata will open, allowing the water to leave.
The Benefits Of Foliar Feeding & When To Use It
Foliar feeding comes with several advantages. Fertilizers that are applied via foliar feeding are usually 3 to 5 times more effective than standard root fertilizers. Foliar feeding can also mitigate any stress that plants feel because of their nutrition. Nutrients from foliar sprays also make elements like iron more accessible to your plants when they would not otherwise be available in the soil, water, or hydroponic solution.
I started foliar feeding my cannabis plants and saw a major difference in the health of my plants. Foliar feeding is just one step in the growing process, starting out with quality cannabis seeds is an absolute must! Get premium marijuana seeds at my shop!
Clearly, foliar spraying is great for correcting nutrient deficiencies because of how fast absorption occurs through the leaves. The results will be almost immediate.

The Ideal Time For Folair Spraying
The ideal time for foliar spraying is the early morning if you’re growing outside and whenever the light turns on if you’re growing inside. The stomata are open when the light is on them. It should be noted, however, that a temperature of 80 degrees or more will make the spray less effective because many of the stomata will be closed.

When a marijuana plant enters
Any fertilizer that is created for soil or hydroponic systems is perfect for foliar sprays (especially ones that have trace elements, or micronutrients). In most cases, you should mix the fertilizers at reduced strength to avoid fertilizer or nutrient burn. A spray with a strong mixture of nutrients couples with bright, intense light can produce
