Hot, dry climates with clear skies don’t have to be kak for marijuana. Most plants in hot climates struggle because they don’t get enough water or have shallow roots which are toasted in the hot upper part of the soil.
If the weed plants are watered enough, the water will penetrate straight down into the soil and the roots will follow it down. During the summer, it’s important to never let the soil dry out. If the water source dries up, the leaves will start to lose the water from their cells.
the plant’s leaves will droop slightly during the hottest part of the day, even when it’s had enough water. This is a normal reaction and is a protective measure used by the plant to avoid getting burnt. When the sun gets too intense for the leaf, it shifts its angle by wilting so that it receives less sunlight.
Marijuana growers might be interested in a few commercial products to help with those sunny, hot, and dry climates. Anti-transpirant sprays will mitigate water loss during, particularly stressful periods. Directions on these sprays indicate that they’re useful for transplanting and for enduring stressful climatic conditions like hot, dry winds. You can find these products at many nurseries.
Another option is water-holders which are made from starch and polymers. They resemble corn flakes and are relatively lightweight when dry. You mix them into the soil and, when they contact the water, they sort of balloon to hundreds of times their weight in water. A single tablespoon of flakes can hold 6 to 8 ounces of water. When the soil dries, the particles start releasing their moisture. The soil maintains its dampness longer and less water is lost overall.
Growing in such hot climates has pros and cons. You do need to go the extra mile to make sure that your thirsty plants are getting the water and nutrients that they need, but a strong source of sun and a decent level of humidity will keep those plants growing upwards.
