As a versatile substance in a cultivator's arsenal, baking soda can be applied as a diluted foliar spray or used directly in the soil. Furthermore, it can be used post-harvest to help remove contaminants from your buds (more on this below).
Baking Soda: To control powdery mildew on plants with a baking soda spray, mix the following in a spray bottle: 1 tablespoon of baking soda, 1/2 teaspoon of liquid non-detergent soap, and 1 gallon of water. Evenly coat the affected plant including the underside of leaves and stems.
Cannabis growers use a neem oil foliar spray together with aloe vera juice and some type of emulsifier like potassium silicate to dissolve the oil. Weekly sprays during the vegetative phase can strengthen plants and increase their resistance against pests and pathogens.
Dissolve 1/4 cup Lemon Juice and 1/4 cup Baking Soda into the 1st bucket. Gently dip, swish, and swirl your freshly cut colas into Bucket 1, then rinse them off by swirling them in buckets 2, then 3. Be careful not to smash them into the sides or bottoms of the buckets. Drip dry, and cure as normal.
Baking soda (sodium bicarbonate) is an antifungal agent and can even kill some established forms of fungus. Research has shown it's effective against some kinds of black spot and powdery mildew. 3 Best of all, baking soda is completely non-toxic for mammals, readily available in any grocery store, and inexpensive.
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
On the other hand, the baking soda and lemon juice used to wash cannabis can kill mold spores and therefore may help prevent mold from growing during drying, curing and storage. However, washing cannabis will not remove advanced mold or “bud rot” that is already present at the time of harvest.
Lack of light is perhaps the most common reason that cannabis produces fluffy, light buds. You may have noticed the lower, puny 'popcorn' bud sites that form below the main canopy. Often these buds are discarded by growers allowing the plant to focus biochemical energy on the main blooms.
Baking soda and Potassium Bicarbonate can help prevent bud rot and can also slow down its spread. Bicarbonates or Baking Soda is a proven method to control powdery Mildew. Its high pH and buffering capacity are also effective against Botrytis Cinera.
To some degree, more light translates to fatter buds and higher yields (you'll need to pay attention to the distance between your grow light and plants or your plant may suffer from light burn). Increasing light intensity is the most effective way to fatten up buds.
Increasing the amount of CO₂ in your grow room can help you grow bigger, denser buds. By doing so, you'll help plants photosynthesise faster and encourage them to take up more nutrients and water.
If not treated early, powdery mildew will continue attacking your crops by damaging the leaves, petioles, stems and buds. If left to progress, your plants will be unsuitable for smoking. Powdery mildew is a common fungus for cannabis crops.
Powdery mildew can be mitigated by spraying the plant's foliage with either baking soda or milk, and both methods are effective. Nonetheless, a 2007 study found foliar milk sprays were more effective than baking soda in preventing powdery mildew.
Baking soda itself isn't normally effective as a powdery mildew treatment, but when it's combined with liquid soap and water, it can be a powerful weapon. It's normally most beneficial if used as a preventative measure rather than a treatment.
The last three weeks is when your buds can actually gain the most weight – that is if you feed them Overdrive®. After your peak bloom phase, your plants enter their late bloom phase (the precise timing and length of which depends on the strain of cannabis you're growing).
If the pH of the growing medium becomes too low or too high, plants lose the ability to absorb nutrients. Low levels of molecules such as iron and magnesium—important for chlorophyll formation and enzyme synthesis—can lead to crispy, dry leaves. A nutrient surplus can also cause dry and damaged fan leaves.
Technically, yes. But practically speaking, it's not ideal. Because high concentrations of sodium are toxic to plants, if you dump a bunch of dry baking soda onto a small plant, it will probably die. Also, because sodium is soluble, it's likely to hurt or kill nearby plants that you didn't want to harm.
Before eating, rinse your mouth with tea, ginger ale or water with baking soda. This will help clear your taste buds. If you have a metal taste in your mouth, try using plastic forks and spoons.
Baking soda contains sodium and sodium is toxic to plants. So yes, if you dump enough sodium onto a plant, it will die. However, sodium is very soluble in water. So when it rains, the sodium is washed into the rest of the soil, where it might kill plants that are not weeds.
Baking soda diminishes the effects of fungal diseases on common ornamental and vegetable plants. Use the mixture on roses (for black spot fungus) and also on grapes and vines when the fruit first begins to appear.
Baking soda is pure sodium bicarbonate, a fine white powder that has many uses. You may wonder about bicarbonate of soda vs. baking soda, but they are simply alternate terms for the same ingredient. If your recipe calls for bicarbonate of soda, it is simply referring to baking soda.
Aside from the anecdotal evidence about human benefits, Epsom salt does seem to help plants. Generations of gardeners have said it helps their plants grow bushier, produce more flowers and have better color. It's also said to help seeds germinate and repel slugs and other garden pests.
