Oyster shell is an excellent organic source of calcium that will accelerate root development and , in turn , improve nutrient uptake . Oyster shell also works as a pH buffer , preventing the soil from becoming overly acidic . Dolomite lime is a rich source of calcium and magnesium , which is very important for all growth stages of the medical marijuana plant . Dolomite lime is also a stellar pH buffer for any soil composition and , as with oyster shell , ensures the soil ’ s pH doesn ’ t turn too acidic .
Early-Season Pests
Pest insects aren ’ t as common during the early growing season as they are in mid to late summer , but that doesn ’ t mean a cannabis garden will be pest free . In the early weeks after planting , a seedling ’ s or plant ’ s most destructive enemies are slugs , snails , or cutworms . These critters usually inflict their damage during the night hours by cutting small plants down to just stalks , completely obliterating seedlings , and / or leaving a trail of eaten leaves on larger plants . To protect a cannabis garden from slugs , snails , and cutworms , growers can implement a variety of defenses against these nasty critters . Diatomaceous earth can be sprinkled around the perimeter of the garden or around each individual plant to create a barrier of protection . Diatomaceous earth is a popular insect deterrent among organic growers and works on a variety of pests , including slugs , snails , and cutworms . The skeletal remains in diatomaceous earth act like tiny razor blades which lacerate the pests as they pass over . Like diatomaceous earth , crushed eggshells act as jagged razor blades that cut open the slugs , snails , or cutworms as they crawl over and cause death by dehydration . Growers can place crushed eggshells around the perimeter of the garden or in each planting container . Another great and inexpensive defense against snails is sand .
“ Once cannabis plants are established outdoors , they have a naturally heightened resistance to pests and pathogens .”
Snails and slugs do not like to cross sand . As with diatomaceous earth and eggshells , a barrier of sand can be placed around the plants to deter any snails or slugs from entering the garden . The sand should be spread at least a quarter-inch high and fine-grade sand seems to work the best . Once a cannabis plant is properly acclimated to its outdoor environment , it will be able to live up to its full potential . After transplanting , the plants will become established and early season pests , such as snails , slugs , and cutworms , will no longer pose much of a threat . In fact , once cannabis plants are established outdoors , they have a naturally heightened resistance to pests and pathogens . This , combined with the presence of natural predators , makes pest control in an outdoor cannabis garden relatively easy compared with indoors .
Cannabis plants that are properly hardened off , carefully transplanted , and supplied with the proper nutrition for the early growth stages and root development will form a healthy root mass and have strong structural integrity , which will be the foundation for enormous cannabis flowers . Patience and attention are required of a gardener in the early stages of the outdoor growing season . However , if the time is taken to properly acclimate his or her plants , provide them with optimal nutrition , and prevent pests , the cannabis cultivator will be rewarded in spades come harvest time .
