Marijuana has evolved over thousands of years to process certain wavelengths (colors) of light that the sun provides, while reflecting most others. The wavelengths it processes for photosynthesis are 439nm and 469nm blue, and 642nm and 670nm red, which are converted by Chlorophyll A and B. HID Grow Lights emit low amounts of light at these wavelengths, focusing the majority of their output in the 500-600nm region (outside of the photosynthesis wavelengths). It is for this reason that HID Grow Lights are quickly being replaced by LED Grow Lights, as LED’s are able to focus their spectrum on the wavelengths plants use most efficiently.
LED Grow Lights
LED Grow Lights are comprised of multiple low-wattage diodes (normally 1W-5W) that work together to create the complex spectral varieties that marijuana requires to grow properly. LED Grow Lights work almost like a puzzle, with each LED wavelength playing a specific role in determining how the plant will grow and produce. By fine-tuning the wavelengths and ratios of a LED Grow Light properly, up to 100% of the light being produced can be efficiently absorbed marijuana plants. This gives LED Grow Lights a huge efficiency advantage over HID Grow Lights, allowing the end user to consume far less energy to achieve similar or better results.
LED Grow Lights provide many additional benefits that HID lights do not. LED Grow light contain no mercury or harmful elements, and as such can be fully-recycled. HID bulbs on the other hand, must be changed at least once per year at a cost of $100-$200! LED Grow Lights also consume about 60-70% less energy, putting money back into your pocket with each power bill. LED Grow Lights also operate up to 600 degrees colder than HID Grow Lights, virtually eliminating the need for ventilation and A/C equipment.

After marijuana became legal in almost 14 states in the US, growing marijuana has become an American pastime. There are many reasons for this and one of the main reasons is for medical purpose. With the increased interest in growing marijuanaindoors, there are many guides available on the internet that people can use to grow marijuana on their own. However, growing, possessing or making use of marijuana is still a criminal offense and is punishable under the federal law. Although the 14 states have legalised the use of medical cannabis, it must be understand that growing is only legal to those who have acquired a license to do so. A license is only issued to patients of serious medical conditions who have the need to usemarijuana in the treatment of their conditions. Apart from the patients, it is those group of people who have acquired a license to operate a medical marijuana dispensary may grow the substance. In this article, I am not going to go into the details of growing this substance at home, but I will simply give an overview of how the process works. This may be useful for those who have acquired a medical marijuana registry card and are looking to grow marijuana at home.
There are four basic steps of growing medical marijuana indoors. These include the following:
1. Getting the seeds – the first and the most essential thing you need to grow marijuana is the seeds. There are many people who have a seed collection of one kind or the other and you can ask your friends whether they have the seeds you use to grow the plant.
2. Germinating the seeds – germinating the seed is a simple process. Although it is possible to get the plants by simply dropping the seeds in moist soil, it is recommended to germinate the seeds first so you can be sure of getting the plants. To germinate the seeds, you can use moist paper towels or a moist sponge.
You can place the seeds in between the paper towels or moist sponge and leave them for a day or two. In a day or two, you will notice that the seeds have already germinated.
3. Planting – once the seed has begun to sprout, you can plant it in moist soil.
4. Lighting – lighting is really important so make sure that you supply enough light to the plants. You can use artificial lights and hang them two inches above the soil.
These are the four basic steps for growing marijuana indoors.
A grow room is a popular home feature for gardeners who want to grow plants indoors without the use of a greenhouse. While some homes come with sun rooms for growing plants, a grow room typically has no windows. The advantages of such a feature are that the gardener can precisely control the amount of light that the plants are exposed to.
Since grow rooms have no natural light, all light must be supplied artificially by specially constructed electric lights that simulate the lighting color temperatures given off by the sun. LED grow lights require no ballast, produce very little heat, and are very inexpensive to operate. These lights are usually placed on a timer so that the plants receive an optimal amount of light. The 600w 3w LED grow light will offer the best canopy penetration if the lights are hung at a height of approximately 4’. At this height, growers will have over 24 square feet of grow space. Closer is better with LED grow lights for hydroponics, if you don’t need 24 sqft, hang it closer for more intensity. If you are switching out your old school HPS or MH for LEDs, do it slowly by weaning your plants off 30 minutes per day until all you have is LED light coverage. This will help avoid shock in your crop. Some growers add LEDs to a traditional HID to create and effective hybrid system.
In most all indoor plant systems including grow rooms, grow boxes and greenhouses, ventilation is an essential component. Plants can only thrive when kept within a certain minimum and maximum temperature range. In a grow room, the heating system controlled by the rest of the building prevents the temperatures from dipping into ranges that are too cold for the plants to survive, but a grow room requires a ventilation system to remove heat from the grow room if needed. This is not as big an issue when using 600w LED grow lighting since the units don’t produce an inordinate amount of heat. Some form of ventilation includes exhaust and circulation fans and vents. Plants really appreciate a gentle breeze in a grow room. This breeze prevents stale pockets of moisture and heat from building up, while also providing a gentle and stimulating exercise for plant stalks. Really. A gentle breeze will strengthen plants and help them to grow better.
Because many of the grow rooms today are sealed against light and insulated for temperature changes, they require internal air filters. Just as humans can become sick when exposed to old, breathed air, plants can grow poorly when grown in stale greenhouse air. Air filters help to recycle the air by pulling it through carbon filters filled with activated charcoal. These filters remove impurities from the air, including spores, dust and mildew that can harm a plant before returning the air to the grow room.
Carbon Dioxide, known as CO2 is a much needed resource for your plants’ development and overall growth. Plants use CO2 in their respiratory cycle, much like we depend on oxygen. Plants can absorb much more CO2 than that which is available at natural atmospheric pressure levels. In most outdoor environments, CO2 is available at 450 parts per million (ppm). Most plants can use anywhere from 1300 to 1600 ppm. This is roughly up to 4X the amount that is available outside. If you give your plants these elevated levels of CO2, you will immediately notice a vast increase in plant growth, development and fruit/production.
The first thing to decide is what method you want to use to enrich your room. The goal is to fill a room with the desired level of CO2 as quickly as possible.
A CO2 Injection System runs off of CO2 gas, (much like a soda dispenser) and is a good choice for a small room. The drawbacks to this kind of enrichment system is the need to consistently change CO2 tanks, and the fact that it can often take a long time to enrich a room. It’s a great choice for smaller systems.
CO2 generators come in one of two ways. You can choose to run it off of liquid propane tanks or a natural gas line. Liquid propane is fine, but the tanks need to be regularly refilled (this can be a real pain). Natural gas runs off of a natural gas line, which once installed properly, is safe, low maintenance and easy to use.
CO2 emitters do not add any extra heat to a grow room, although CO2 generators do. Depending on the size of generator you choose, you may be adding a considerable amount of heat to you grow room.
There are other DIY methods of creating CO2 including, brewing with yeast and using a fungus cultivation system. Do your research and have fun.
