Carbon dioxide is essential to the process of photosynthesis. Most plants grown indoors require a minimum co2 concentration to enable them to photosynthesise efficiently and produce energy in the form of carbohydrates. These concentrations of co2 are enough for plants to grow and develop normally. Lower concentrations can seriously impede plant growth and general plant health.

In fact, a drop of 25% in natural co2 concentrations can easily inhibit growth by over 50%. Consequently, the grow room should be set up to replenish co2 levels throughout the plants daytime. Natural ventilation [using convection or chimney effects] or forced ventilation [using intake/exhaust fans] can usually ensure that this objective is met adequately. When using airbombz – dependant on the light source – no air intake or extraction is needed. However if temperature problems do arise then a timed exhaust fan will usually correct any temperature issues… remember though higher temperatures are needed for co2 to be used correctly.

The cannabis plant has a history of medicinal use dating back thousands of years across many cultures. Medical cannabis ,or medical marijuana, is cannabis and cannabinoids that are recommended by doctors for their patients. The use of cannabis as medicine has not been rigorously tested due to production restrictions and other governmental regulations. Limited evidence suggest cannabis can: reduce nausea and vomiting during chemotherapy, improve appetite in people with hiv/aids and reduce chronic pain and muscle spasms along with helping many many ailments associated to other conditions such as M.S., parkinsons, seizures, epilepsy, fibromyalgia, anorexia, arthritis, migraine and glaucoma along with many other health problems. A 2017 review found moderate to high quality evidence for effectiveness of cannabis in relieving chronic pain in many many conditions.

Medical cannabis can be administered using a variety of methods, including liquid tinctures, vaporising or smoking dried buds, eating cannabis edibles, taking capsules, using lozengers, dermal patches, or oral/dermal sprays and oils. The medical use of cannabis is legal in a number of countries, some of which include Canada, Chile, Colombia, Germany, Greece, Spain, Ireland, Israel, Italy, Netherlands, Poland, Peru, Portugal and Uruguay and USA. Australia has passed laws to allow the use of cannabis for medical and scientific purposes in some states. In The United States,29 states and the district of Columbia have passed legislation permitting the possession, use, and distribution of medical cannabis in some form.

Medical organisations that have issued statements in support of allowing access to medical and recreational cannabis include the American Nursing Association, American public health association, American medical student association, National Multiple Sclerosis Society, Epilepsy Foundation and Leukemia and Lymphoma Society. These are just a small amount of medically recognised organisations and publications that support cannabis use around the world.
